Renewable gases – Biomethane and Hydrogen


Role Description
I work for Nortegas Green Energy Solutions. Nortegas is a gas distribution company in the North of Spain. My mission is to develop the renewable gas market in Spain to displace the natural gas and replace it with renewable gas.

In the past I have worked in resource recovery and over the last 15 years I have focused in developing anaerobic digestion plants. Given this experience my focus within Nortegas is biogas but I am taking the opportunity to also get involved in the Hydrogen market when I can. I also represent the World Biogas Association in Spain.


Why is female representation in biogas important?

Within the biogas industry there are lots of different roles and disciplines. Some of them have a strong female representation but others have a very thin female presence, for instance in construction or plant operations. This is not only a missed opportunity as women have so much to offer but the imbalance also makes more difficult for those women already in the industry. Having a balanced representation ensures that everyone is listened to and ensures that women´s needs are considered. Something as simple as having a female toilet is not a given on a construction site!

London, United Kingdom

Area of Work
Strategy and business management, stakeholder engagement, business development


Role description

I lead our team at the World Biogas Association, working hard to ensure that the work we do will have the biggest impact, engaging with our Council and members to understand their challenges, how we can best support them through our work and facilitate collaboration with third party stakeholders. I frequently make presentations at conferences and attend meetings with global organisations such as the UNFCCC, CCAC, IEA, GMI and participate in COPs on behalf of the association. 

Why is female representation in biogas important?

As so many studies show, a minimum of 20% of women at board level improves business performance. Meeting the Global Methane Pledge will require all businesses in the biogas industry to outperform and grow exponentially, so they will need to ensure as diverse an employee base as possible, including women.

Career path

Following a gap year in Guatemala leading a weaving programme for Highland Indians I started my legal training to become a solicitor in the UK. After practicing as a solicitor for 10 years, latterly for a US law firm, and completing an MBA at London Business School, I set up my first business, WhizzGo, which offered cars for hire by the hour near you to reduce car ownership. Following the financial crash, which resulted in the business being acquired by a global car hire firm, I was asked to set up the business side of the UK’s anaerobic digestion association (ADBA). A few years ago the need for a global association to represent this critically important industry became apparent, which lead to the establishment of the World Biogas Association, and I am now in the process of moving over to run that full time.

Educational background

  • A degree in English and French Law from the London School of Economics and Political Science (LSE)
  • Diplome d’Etudes Juridiques Francaises, University of Strasbourg

I am involved in creating the strategic and sales plans for the company. I have been involved in expanding global production capacity to keep up with our rapid growth.

Why is female representation in biogas important?

Studies show that organizations with women in leadership roles outperform those with only males. The global biogas sector has a strong role to play and needs to scale rapidly to mitigate methane emissions in addressing the climate crisis. Women can play a major role in accelerating this growth in the sector, addressing the inequality gap of women in green tech.

Elnaz Bahadori

Project Leader & International Business Developer, Renergon
Lengwil, Switzerland

Area of work
Biogas, biomethane and biochar markets


Role description

I started my career path in the biogas industry in Spring 2020 with Renergon in Switzerland. Renergon is one of the pioneers in the solid-state anaerobic digestion and with its own patented RSD® technology is offering one of the most innovative ways to treat organic waste with the aim of biogas & high-quality compost production.  Since last year, I focus mainly on company’s business development strategies worldwide. My main role is to seek new market opportunities and to develop new short/long term strategies in the field of Biogas, Biomethane & Biochar.

The outcome of these business strategies is to lead the company’s goal toward Biogas upgrading & Biomethane production. In this regard, with the support of our technical & engineering department we are developing the Biogas upgrading unit based on PSA technique with the relatively low investment & operation cost. This could be an interesting alternative for many biogas plants which are currently running with CHP units.

In the framework of my business development activities, I am also responsible of Renergon’s carbon market group. We have established together a working group for screening the different carbon markets, CO2 emission saving calculations and CO2 emission certificates, mainly for AD biogas plants. The aim of this group is to find the most profitable business model for biogas production not only for company’s future strategies, but also for our existing clients in the biogas sector. We believe that the impact of the carbon credit revenues will be an important booster in the biogas sector.

Why is female representation in biogas important?

Women are more patient in their job, and they are prouder of their accomplishments and the honor and feeling of satisfaction which their role can bring to them. The biogas industry is a mix of engineering details and creativity in finding the most sustainable way for waste treatment and reducing carbon footprint. Both can be a perfect match for an engaged woman driven with a sprit of environmental respect.

Career path

In 2014 I received a full fund scholarship from the University of Politecnico di Torino in Italy, to pursue my higher education career as a PhD in Materials Science. My focus was on nanomaterial synthesis & surface characterization. Within my PhD career I did several research collaborations with Italian & Swiss universities. The aim of these collaborations was to find out the best applications for wastewater treatment or CO2 adsorption for specific type of nanomaterial synthesised by our research group. The outcome of my PhD career was several publications in high impact factor journals.

My PhD career opened many doors of opportunities for me, from which I have been selected as a winner of Postdoctoral fellowship at the University of Milan. There I had an opportunity to work in department of material engineering & Industrial chemistry with an expert high level academic group. I was responsible for several research projects in a collaboration with the University of Genova, Politecnico di Milano and University of Stuttgart.  The focus of my research activities was photocatalytic Synthesis of Robust Catalyst to Upgrade Low-Value Biomass Stream & photocatalytic H2 production from waste carbohydrates.

The postdoctoral period opened my eyes towards waste management and in particular biofuels formation from waste. I consider this period as a successful transition in my career path from academy to industry.

Below are the summary of my achievements withing 2 years of my postdoctoral career:

  • I have Published at least 16 articles in peer reviewed journals, from which in 6 I was the first author.
  • I won the award of “The most innovative ideas to manage the problems related to the nitrogen cycle” in the ICS2019 winter school
  • I authored the 15th chapter of the book named “Nanomaterials for the Detection and Removal of Wastewater Pollutants” from Elsevier.

After moving to Switzerland, I was so determined to continue in waste management & biofuel sector. There I was so delighted to start my industrial career path in biogas industry with one of the most innovative companies Biogas sectors on Spring 2020. For the last 2 years that I am working with Renergon, I have been Involving in various disciplines within the company structure, from engineering & technical specifications to project management both in national and international projects.

One of the great honors & career achievements for me as a woman in the biogas industry, was being a leader of our company’s engineering team for designing & engineering the largest biogas plant in Gaziantep city in Turkey on Sep 2020. We were able to follow the project from remote for about 15 months from initial steps to the end of construction.

The Gaziantep Mechanical Biological Treatment and Biogas Facility (MBT) has been realized under the UNDP’s “Turkey Resilience Project in Response to Syria Crisis. With about 10 million USD investment cost, this project is one of the largest projects of UNDP for improvement of city’s infrastructural and municipal waste management service.

The Renergon designed the solid-state biogas facility which can treat 22,000 t/year municipal organic waste (MSW). The biogas yield has been estimated c.a. 2,000,000 Nm3/year & correspond methane of yield c.a. 1,200,000 Nm3/year. Apart from its economic benefits, this facility is also expected to play a vital role in the reduction of greenhouse gas emissions (GHG) through avoiding fugitive methane in landfill and replacing fossil fuel use by biogas. Thanks to these, the facility is aimed to reduce 9,309 tCO2eq emission per year.

This Plant is ready to start running with organic substrate in March 2022.

Educational Background

I did both my bachelor’s & master’s degree in Iran. Thanks to my parents’ support & their sensibility for my future success, I was able to attend to one of the best universities in Iran. After finishing my master’s degree in 2012, I was determined to continue my higher education abroad, therefore I applied to several positions in the USA, Canada & Italy. Now looking back, I am so happy that Italy was my destination for higher education.

Microbiology, Process Development


Role description
Managing the microbiome department which optimizes the waste treatment process by analyzing the active microorganisms by molecular biology and bioinformatic tools.

Why is female representation in biogas important?

I think that anaerobic digestion processes are perceived as being physical labor and therefore fewer women choose biogas as a career path. However, today thanks to automation, in-line sensors, analytic analysers and AI, enable to manage the processes with high precision and the operation and maintenance has become much easier to handle. This change in operations made it possible for more women to join and take part of the biogas development. As an example, at SGTech, I was the 3rd female to join (out of 18) back in 2018. Today, I manage an all-female department, 6 team members from different disciplines, chemistry, engineers, microbiology and data analyst. We work together and set the tone at discussions and decisions making. The change that I see at SGTech can and should be in every biogas company.

Katharina Pröstler

Gender, Environmental and Social Safeguards Specialist,
Also Gender and Youth focal point, Department of Energy at the United Nations Industrial Development Organization (UNIDO)

Vienna, Austria

Area of Work
Gender diversity, Environmental and Social safeguarding


Role Description
Katharina is responsible for promoting gender equality and the empowerment of youth and women, as well as for ensuring compliance with social and environmental safeguards of sustainable energy, climate change mitigation and adaptation projects. Her current focus is on catalyzing action to enhance gender equality and women’s empowerment for a just, inclusive and equitable energy transition.

Why is female representation in biogas important?
Energy is very important in women’s daily lives. Billions of women around the world still lack basic access to affordable, reliable, sustainable, and modern energy, negatively impacting their enjoyment of all their fundamental human rights, including their health, well-being, livelihoods, and local environment. Achieving sustainable energy for all is critical to the achievement of women’s human rights. At the same time, women have a critical role to play in achieving sustainable energy for all, but barriers in access to education, finance, career advancement, and insufficient involvement in decision making processes prevent them from leading, innovating, participating in, and benefitting from the clean energy transition on a level playing field with men. Ensuring access to clean, modern and sustainable energy solutions, such as biogas for women is a fundamental element of a just and inclusive energy transition.

Women should have equal opportunity to lead, participate in and benefit from biogas. It is well-documented that women in leadership positions enable companies to be more innovative, helping them to improve their overall performance. S&P 500 companies with higher numbers of women in senior management saw a 30% higher return on equity and a 30% lower earnings risk relative to lower-ranked peers.   Therefore, enhancing gender diversity is not only a human right, but it also makes business sense.

Career Path
Katharina has over 11 years of professional experience as a project manager and in promoting sustainable and inclusive development, in particular climate change mitigation and adaptation. Katharina has worked in the private, public, and academic sector and at UNIDO she implemented projects in the area of cleantech innovation entrepreneurship and sustainable energy technologies in Thailand, in Lao PDR, in Cambodia, and in Vietnam. She has worked on promoting biogas in Cambodia and helped to set up a Biogas Technology and Learning Centre in the country.

Moreover, she has studied, lived, and worked in many countries, including Austria, Belgium, Cambodia, Ecuador, England, Germany, Laos PDR, Spain, and Thailand. She also acts as mentor for women and youth supporting the Global Women’s Network for the Energy Transition (GNWET) and the SDG7 Youth Constituency.

Lily Bernadet

New Business Development, Storengy
Northwich, United Kingdom

Area of Work

Business Development – Investments in Anaerobic Digestion Infrastructure


Role Description

Lily works for Storengy, part of the ENGIE Group, which is very active across the green gas supply chain from research and development through to the production, optimisation, and trading of the biomethane and associated co-products such as CO2.

“Whilst we are a very small team in the UK, we are supported by the wider ENGIE group expertise and ambition to play a significant role in the production and development of biomethane production sites in the UK.

“Storengy is currently storing and trading natural gas from its underground storage site in Northwich, UK. The process of producing biomethane is thus a new market for us and as such, the role is very versatile. It is like working for a start-up – we need to define and implement the strategy, grow, and transform the business as we start developing a portfolio of production sites – with sustainable investment in biomethane production infrastructure as our prime objective to actively contribute to the decarbonisation of the UK gas network”.

Why is female representation in biogas important?

I believe in equality. Everyone should have equal chances to learn, work, and be successful. Gender equality at work, especially in engineering and energy production is lacking behind. Regardless of our gender and personal background we should all have equal opportunities.

Linda Nordin

Senior Waste, Resource and Circular Economy Consultant, GHD

Queensland, Australia 

Area of work
Development of circular, sustainable and financially efficient business models


Role description
I have both local and international experience having worked for Local Government Authorities in Australia, UK and Sweden and I have an exceptional understanding of risk mitigations with waste and recycling collection and treatment services, alternative waste technologies and the governance frameworks for the development and implementation of waste and resource recovery strategies. I also work with the mindset that there is not one solution fits all, but there is one solution for all.

In my current role, central to development and implementation has been a focus on developing circular and sustainable business models suitable that meets the clients’ needs in a financially efficient way.

Why is female representation in biogas important?

Technical categories usually has a high percentage of male representatives and the discussion can become very technical. I have found that you have to work harder as a female to be respected. This can also be positive as when you work hard you also become more and more knowledgeable over the years. Females very often work in this field, myself included, to support a bigger cause such as reducing the impacts of climate change. This is very important for the future and I believe that us females have a big role to play when it comes to communicate the role of biogas and the impact it can have on our communities (the world).

Career path
2020 – present
GHD – Australia

City of Gold – Queensland, Australia
Business Efficiency Officer then from 2017, Senior Waste Project Officer

Täby kommun – Täby, Sweden
Project manager Waste and Recycling

Sita UK (Suez) – London, UK
Recycling Coordinator & Manager

I have 18 years’ experience in waste management and practical understanding of how to build up a circular economy. I have long experience in planning and implementing Waste and Recycling services, focussing especially on developing a circular economy for Organics. I launched a green organic collection service in the UK in 2006, and food organic collection for Anaerobic digestion in Stockholm, Sweden in 2010. More recently, in 2018-19 I undertook a feasibility study and road map for FOGO services and implemented the first Council-operated commercial food waste service in QLD for City of Gold Coast to produce AS4454-compliant compost. Furthermore, I have participated in the development of sustainable precincts where modern technologies were used for example Insinkerators, Waste vacuum system, Dehydrators, Composters.

Over the years, I have worked with applying mathematics on waste management solutions to try and find cost-efficient yet innovative and circular solutions that can divert waste away from landfill, help us achieve net-zero and reduce human impact on climate change. I have found an particular passion closing the loop around Organics and how this material can be used for production of renewable energy, biofuel and a biofertilizer. I am excited to help Australia start its journey in this sector and to understand and explore more on how and if biogas also can be used to produce green hydrogen in the future.

I love seeing how society (over the last decade) is slowly changing from thinking that sustainability solutions and climate change is “just for green hippies” to now becoming part of the new norm and a must for our society to survive. Biogas production is part of this evolution.

Educational background

I work as a consultant in the areas of stakeholder engagement, gender equality and social inclusion, communication, and international relations. I am one of the founding leaders of the network “Mulheres do Biogás” (Women of Biogas), an initiative supported by Instituto 17, an NGO in Brazil.  

Why is female representation in biogas important?

Like in any area in society, women’s participation in the biogas sector is what makes it possible to reach its full potential. If we are to continue debating sustainable development and energy transition, women must be part of the discussion. Increasing female representation within the biogas industry requires the involvement of women from all over the globe and from diverse backgrounds.

Career path

I started my biogas career while still in college, becoming part of the International Center for Renewable Energies and Biogas (CIBiogás). In this institution, I was an Institutional Relations and Communication intern for two years. After graduation, I worked as a freelancer Communications Assistant for the Latin American and Caribbean Biodigesters Network (RedBioLAC). Between 2020 and 2022, I was a consultant on Stakeholder Engagement, Communication, and Gender Equality and Social Inclusion at the Brazil Energy Program (a British government programme) in the waste to energy component via Instituto 17.

Paola Petry

Product Manager of Clean Energy and Renewables, Comgas – Natural Gas Distribution Utility

São Paulo, Brazil

Area of work
Open Innovation, research, biogas, biomethane, gender equality


Role description
With the Comgas, I am part of the “Plugue” team. This is an open innovation hub that seeks to help innovative projects come to fruition, connecting partners, startups, investors, universities and people from around the world to transform the gas and energy sector in Brazil. I am responsible for managing projects related to clean energy and renewables. Many projects I follow are in the area of ​​biogas and biomethane, decarbonization and waste to energy. I am one of the founding leaders of the network “Mulheres do Biogás” (Women of Biogas), an initiative supported by Instituto 17, an NGO in Brazil

Why is female representation in biogas important?
The biogas sector, as well as others related to renewable energy, was born with greater ease to be more diverse and provide gender equality, as it is more connected with modern trends. However, there are still barriers for equal opportunities and recognition between men and women. Thus, initiatives such as this working group are important to dialogue with the biogas sector and build agendas to enable the continued growth together with actions for equality. Women need to have their skills recognized and expanded to be able to help the biogas sector to develop and also to pave the way for other productive segments that need to improve in terms of social inclusion, gender and diversity. This is a path to be traced collectively, showing that inclusion is fundamental for sustainable development.

Career path
At the University of Sao Paulo, I experienced different technical work themes involved with research and development projects. This base was important to work in the management of innovation projects, which I currently exercise at Comgas, the largest natural gas distribution utility in Brazil. During my master’s degree I started my studies in the area of ​​energy planning and biofuels and taught classes related to energy transition and regulatory aspects. Subsequently, I worked together with projects and companies with consultancy and support for publications about biogas and biomethane sector in Brazil. I am currently in my PhD doing experiments with co-digestion of different substrates to optimize biogas production and I am part of the Brazilian “Women of Biogas” initiative, that also seeks to promote gender equality.

The first dedicated rDME plant will be built in the UK in 2023, producing 50ktonnes/year of rDME for the LPG sector. This multimillion GBP investment will dramatically accelerate the ability of the LPG industry to reduce its greenhouse gas emissions. From a first commercial plant in the UK, Circular Fuels Limited already has plans to develop 5 other plants across Europe and North America over the next 5 years. 

Why is female representation in biogas important?

Gas – particularly in easily transportable safe, efficient liquid form – is an essential part of the energy mix today.  Our challenge and opportunity is to make the best use of all available feedstock and resources to produce biogas that can completely replace poor air quality and carbon intense fossil energy sources. This will take collaboration, perseverance, creativity and communication.  Above all it will take the best brains and at least 50% of these are owned by females! 

Career path

I’m currently enjoying my 27th year in industry having followed a rather eclectic career path.  The first 11 years were in FMCG both on client and agency side learning how to get things done creatively, with multiple stakeholders and with a diverse team on time and in budget.  Then the love affair with energy began when I joined GE Oil & Gas in 2006.   I cut my teeth on subsea engineering and the wonderful complexity of energy.  In 2012 I moved over to focus on renewable energy at the Dutch research lab TNO (called Energy Research Centre at that point) where I led Business Development for Biomass and Energy Efficiency in Industry.  I joined SHV Energy in January 2018.

Educational background

  • BA Hons Japanese & Business Studies
  • Postgraduate Chartered Institute of Marketing accreditation
  • Leadership courses including “Taking the Stage” which I would recommend to all Female Leaders
  • Specialism in Non-Executive Director Governance

Why is female representation in biogas important?

Female representation has increased over the years in the biogas industry, but there is room for improvement.  The biogas industry is dynamic and offers a career path that aligns with core values that prioritize a brighter future, such as reducing negative impacts on the environment and proliferating the use of clean technology.

Career path
My previous technical experience lends well to my current role in the biogas industry.  During my time at the University of Waterloo, I had co-op jobs in different industrial laboratories which helped me get my first job out of university at a waste-to-energy plasma gasification plant.  I worked at the full-scale demonstration plant, setting up the on-site testing lab, and sampling and testing material from the plant during operation runs. This experience fostered an interest in waste-to-resource technologies, and I sought out more experience by working on relevant projects for private and public agencies in technical, research, and business development capacities. These experiences led me to the CBA where I have been working since 2017. My familiarity of the technology and overall knowledge of the waste-to-resource sector is a key part of appreciating where biogas fits in the circular economy and renewable energy space and understanding the challenges our members face to identify potential solutions

Why is female representation in biogas important?

I gained most of my experiences in the biogas sector through the international visits to many international biogas production plants and companies specialized in this field in different countries, which I learned over time the importance of female interaction in this aspect, and their high ability to gain and share knowledge. The biogas sector, like any other sector, must thrive, with Gender-balanced experiences, which provide diversity of thought in work and promote knowledge sharing in large scale.

Role Description

As bioenergy advisor, I am the focal point and person in charge of bioenergy related activities at GIZ Indonesia. The project I am working on is one of GIZ Indonesia’s energy programme. Our strategic partner is Directorate Bioenergy, Ministry of Energy and Mineral Resources. Here, I am responsible to do research and study related to bioenergy technologies under Indonesian market condition. I also initiate and develop cooperation with national and international stakeholders in promoting bioenergy development in Indonesia.

Why is female representation in biogas important?

I personally think that women’s representation in biogas sector is essential. This is not only a matter of fairness, but also, I believe women could provide valuable perspectives especially in the decision-making process. The representation of women in biogas in particular – technical roles is also important to erase the knowledge gap between male and women. Furthermore, it could potentially give positive impact to the development of social and economic aspect.

Career path

My first professional job was to be a project coordinator at PT AES AgriVerde in Jakarta for one year. It is a company that focused on biogas technology. The company has several biogas installations in palm oil mills in which the feedstock come from palm oil mill effluents (POME). Initially, the revenue stream was generated from certificate emission reduction through the clean development mechanism (CDM). However, since the CO2/ton price dropped significantly, the business shifted to selling biogas to be sold to electricity grid.

During my master’s degree, I had the opportunity to do my master’s thesis at the Helmholtz Centre for Environmental Research (UFZ) in Leipzig for 8 months. The main topic of my thesis is on nitrogen removal using partial nitritation/anammox method in a pilot scale reactor.

To date, I am working as bioenergy advisor at GIZ Indonesia in Jakarta since 2020.

Educational background

I did both my bachelor and masters studies in environmental engineering study programme. I obtained my master’s degree at the Technical University of Munich in 2019 which focuses on two major topics: urban water system engineering and water food energy nexus.

Why is female representation in biogas important?

Career Path

Before I start on my professional career, I would like to note that I started part time work whilst still in education. From 16 I had two part time waitering jobs which empowered me to have financial independence and start building on the non-academic qualities that are vital for a professional career such as confidence, people skills, time keeping etc. Whilst the balance between education and part time work is very important, do not underestimate the importance of having experience outside of academia as ultimately, I have been told that this attitude to work is what helped my current employer make the decision to hire me.

My first professional job from university was as a Trainee Proposals Engineer with Clarke Energy. Clarke Energy supply, install and maintain reciprocating gas engines that are installed for various industry applications and on a large range of gases. A proposals engineer is responsible for reviewing customer specifications, starting to put together a concept engineering design then costing/presenting this design to the customer. The training for the role was very much a learn on the job type of scenario which in my opinion is the best way to learn! I progressed quickly from trainee proposals engineer (2013) to proposals engineer (2014-2016) and then to senior proposals engineer (2016-2021) who was responsible for all the proposals into Africa and the US. The nature of the proposal’s role is that it is multidisciplined and you require as much commercial knowledge as you do technical knowledge, and it really is a jack of all trades type of position. During my time as a proposal engineer, I had exposure to many varying types of applications but the one that interested me most was the biogas applications.

Educational Background
During primary and secondary education I was quite the know it all, I seemed to excel quite easily and was always in the upper percentile of the class. I first received a shock to the system when moving to college, the shift in the intensity of the subjects that I had chosen (Biology, Chemistry and Maths) was quite a difficult thing to deal with and certainly didn’t marry up with my high aspirations of becoming a medical doctor! During college there was a realisation of what my strengths where and it turns out after a shaky start, that was maths. With this realisation once I had received my A-Levels I applied for a maths degree and was successful with Manchester Metropolitan University (after going through the clearing process which was certainly a knock to my self-confidence!).

I had a good start on the BSc Mathematics course, but something did not feel like a good fit. I was used to dealing with pure maths and the course was starting to introduce applications such as finance/programming. After some careful consideration I decided this was not for me and I applied for a place on Manchester Metropolitan’s BEng Mechanical Engineering course. I was successful on the course and received a 2.2 Honours degree in the end (the dissertation was not my favourite!) and quite shortly after moved into my first role with Clarke Energy.

If there is anything that I take from my education is that whilst it is important and it introduces you to a vast amount of knowledge, ideas and skills, I was not in fact as academic as I initially thought. But with perseverance, I was ultimately successful with my grades and there were even greater qualities that I built on and these turn out to be a lot more important in your career path.
