This week on RNG Girls, Lisa Kitt and Skye Austin are joined by James Earl, Chief Executive of Future Energy Networks, for a conversation on gas infrastructure, biomethane, home heating, data centers, energy security and the future of the UK energy system.

Future Energy Networks represents Britain’s gas networks and works across policy, regulation, technical issues and long-term energy strategy.

This episode looks at the energy transition through a whole-system lens.

We hear a lot about electrification, and rightly so.

Electrify transport.
Electrify heat.
Build more renewable power.

But as electricity demand grows across homes, industry, transport, AI and data centers, the question becomes more complicated:

What happens if we try to electrify everything at the same time?

Britain already has an enormous gas system beneath its streets. It heats homes, serves industry, stores energy and supports the electricity system during peak demand. As the molecules moving through that system become increasingly renewable, could gas infrastructure become part of the solution rather than something we simply leave behind?

The conversation gets practical:

🔹 Why Britain’s gas network still matters
🔹 How biomethane could support UK energy supply and security
🔹 What bio-hybrid heating could mean for hard-to-electrify homes
🔹 Why winter peak demand changes the infrastructure debate
🔹 How data centers are adding new pressure to the electricity grid
🔹 Why gas infrastructure and biomethane could support flexible, reliable power
🔹 Why the future may be less about gas or electricity, and more about using both well

James also explains why policy clarity matters if the UK wants to unlock the next wave of biomethane projects, and why a truly integrated energy system needs to start with the infrastructure we already have.

It’s a strong listen for policymakers, energy networks, biomethane producers, developers, utilities, infrastructure leaders, data center operators, investors and anyone interested in what a practical, resilient Net Zero energy system could look like.

This week on RNG Girls, Lisa Kitt and Skye Austin are joined by Ashley Remillard, Executive Vice President of Legal & Government Affairs and General Counsel at Hexagon Agility, and Executive Team Member at The Transport Project.

Ashley works at the intersection of renewable natural gas, transportation, policy and global market development, helping shape conversations in the United States and beyond.

This episode looks at RNG through a transportation lens, exploring how smart regulation, market design, infrastructure investment and government-industry collaboration can accelerate real-world adoption.

Because RNG is no longer just an environmental story.
It is becoming a transportation story.

From California to Europe, India, the UK and beyond, fleets are using renewable natural gas to reduce emissions, improve fuel security, support heavy-duty transport, and create cleaner operations with technology that is available today.

The conversation gets practical:

🔹 Why heavy-duty transportation is such an important market for RNG
🔹 What the US can learn from global approaches to RNG-powered transport
🔹 Why lifecycle emissions matter when measuring real impact
🔹 How California helped show what is possible through the LCFS
🔹 Why refuse trucks, transit buses and long-haul fleets are strong use cases for RNG
🔹 How energy security and fuel resilience are becoming part of the transport conversation
🔹 Why regulatory certainty can be as important as financial incentives
🔹 Why smart policy should focus on outcomes, not picking winners

Ashley also shares why RNG has such a powerful role to play in decarbonising transport, particularly in heavy-duty applications where the technology, infrastructure and fuel are already available.

It’s a strong listen for fleet operators, policymakers, developers, infrastructure providers, investors, transport leaders and anyone interested in cleaner, more resilient transportation systems.

This week on RNG Girls, Lisa Kitt and Skye Austin are joined by Brad Pleima, President of EcoEngineers and Co-Vice Chair of the American Biogas Council, for a conversation that looks beyond RNG, and into the wider low-carbon economy.

Through EcoEngineers, Brad works across renewable natural gas, sustainable aviation fuel, renewable diesel, ethanol, hydrogen, carbon markets and emerging low-carbon technologies.

That broader perspective gives him a unique view of what RNG is doing well, where the industry still has room to grow, and what lessons can be taken from the markets developing alongside it.

Because renewable natural gas no longer exists in a vacuum.

It is part of a much larger low-carbon economy where projects are competing for capital, customers, policy attention, talent, public trust and long-term demand.

This episode explores what it will take for RNG to become stronger, more competitive, and more resilient as the market moves into its next phase.

The conversation gets into:

🔹 Why RNG is becoming a more global market
🔹 Why execution and operational excellence are becoming major competitive advantages
🔹 What successful companies do differently as markets tighten
🔹 Why compliance, data and regulatory discipline matter more than ever
🔹 How RNG can learn from renewable diesel, ethanol, SAF, hydrogen and carbon markets
🔹 Why the industry needs more markets, more demand and stronger offtake
🔹 Why RNG needs to tell the full story — not just economics, climate, jobs or energy, but all of them together
🔹 Why the future of RNG depends on collaboration, trust and learning from projects already in the ground

Brad also explains why RNG’s versatility is one of its biggest strengths: from pipeline-quality gas and electricity to hydrogen, SAF, bio-LNG, biomethanol and lowering the carbon intensity of other energy products.

It’s a strong listen for developers, operators, investors, policymakers, technology providers, fuel market participants, and anyone thinking about what it really takes to build an industry that lasts.

This week on RNG Girls, Lisa Kitt and Skye Austin are joined by Corina Sheridan, Executive Vice President of Business Development at Viridi Energy, for a practical conversation on what the next generation of RNG development needs to look like.

Corina brings more than 20 years of experience across energy and sustainability, with work spanning municipalities, utilities, private partners, landfills, digesters, organics diversion and agricultural waste sectors.

Together, they explore what happens as the RNG market moves beyond incentive-driven growth and into a more disciplined, long-term phase of development.

Because incentives can help projects pencil.

They can help attract capital.

They can move some projects from interesting to buildable.

But they do not replace good projects.

This episode gets into the real work behind renewable natural gas development, from deciding whether a project should be built, to understanding whether it can be built successfully.

The conversation covers:

🔹 Why RNG development is about more than finding projects
🔹 How developers align municipalities, utilities, landfill owners, investors, operators and communities
🔹 Why trust, communication and relationship-building matter across long project timelines
🔹 What makes a project attractive — and what early warning signs developers need to watch for
🔹 Why saying no, or “not right now,” can sometimes be the best development decision
🔹 How longer timelines, changing economics and evolving incentives are reshaping project strategy
🔹 What has to replace incentive-driven development as the market matures
🔹 Why the future of RNG depends on stronger projects, stable demand, disciplined execution and long-term value

Corina also shares why RNG is still one of the most versatile resources in the renewable energy transition, supporting methane reduction, waste management, agriculture, local economies, domestic energy security and reliable renewable energy.

It’s a strong listen for developers, operators, municipalities, utilities, investors, policymakers, technology providers and anyone trying to understand what it really takes to move RNG projects from idea to operation.

This week on RNG Girls, Lisa Kitt and Skye Austin are joined by Jan De Clerck of Poul Schmith, Nichlas Rasmussen of Green Giraffe Advisory, and Line Lundbye of EIFO for a conversation on one of the biggest questions facing the European biomethane market:

How do we close the gap between ambition and reality?

The conversation originated at the Biogas Capital Forum in Copenhagen and looks at Europe’s goal of producing 35 billion cubic metres of biomethane, an ambitious target, but one that depends on more than policy ambition.

Because targets don’t build projects.

People do.
Capital does.
Execution does.

Together, Jan, Nichlas and Line explore what it actually takes to move biomethane projects from idea to investment-ready infrastructure, and why the industry now needs stronger alignment between developers, financiers, lawyers, offtakers, regulators, farmers and technology providers.

The conversation gets practical:

🔹 Why Europe’s biomethane market is attracting attention from investors, lenders and policymakers
🔹 Why capital is available, but not every project is structured in a way that capital can support
🔹 The gap between policy ambition, regulation, certification and projects reaching financial close
🔹 Why developers need to think about bankability from day one — not when the project is “ready”
🔹 How feedstock security, offtake, certificate pricing and cross-border regulation affect investor confidence
🔹 Why the industry needs to balance flexibility with the certainty lenders need
🔹 Why proven, repeatable and “boring” projects can often be more financeable than overly complex ones
🔹 How future value streams such as CO₂ liquefaction, CCS, SAF, e-methane and other pathways are shaping project design

It’s a strong listen for developers, investors, lenders, lawyers, advisors, operators, policymakers and anyone trying to understand what needs to happen for Europe’s biomethane ambitions to become real, investable projects.

This week on RNG Girls, Lisa Kitt and Skye Austin are joined by Chris Negus and Andrew Rice for a practical conversation on one of the RNG industry’s most important, and often least understood areas: project finance.

Chris Negus is Managing Partner & Chief Executive Officer, with more than 10 years’ experience across banking, commercial lending, business development, M&A and biogas project finance. He has helped facilitate over £160m of debt and led ten M&A transactions worth £400m.

Andrew Rice is Managing Partner & Chief Operating Officer, with more than 30 years’ experience in retail and commercial finance, including leadership roles at HSBC, NatWest, Citibank and BMW. He has refinanced over £175m and brings extensive relationship management and restructuring expertise.

Together, they explain what makes an RNG project investable — and why even the strongest technical project cannot produce a molecule without funding.

The conversation covers:

🔹 How project finance differs from corporate finance
🔹 Why lenders assess the team as closely as the project
🔹 The importance of feedstock security, offtake, contracts, operators, counterparties and sponsor experience
🔹 Why trust, transparency and relationships matter as much as spreadsheets
🔹 Why technically strong projects can still be unfinanceable
🔹 How weak assumptions are exposed in difficult markets
🔹 How developers should approach optionality, molecule value, SAF, marine fuel, bioCO2, carbon capture and future pathways

This episode is for developers, operators, investors, lenders, farmers, technology providers and anyone interested in how RNG projects move from concept to infrastructure.

Before the steel, concrete, compressors, membranes or pipelines arrive, someone must believe in the project enough to fund it.

This week on RNG Girls, Lisa Kitt and Skye Austin are joined by Charlotte Morton OBE, Chief Executive of the World Biogas Association, for a special bonus episode celebrating 10 years of WBA and the upcoming World Biogas Expo / ADBA Conference.

Charlotte has spent nearly two decades working in biogas and has helped build the World Biogas Association from its launch at COP22 in Marrakesh in 2016 into a global voice for the industry.

This episode takes the conversation beyond local markets and looks at biogas through a global lens, as a climate solution, methane mitigation tool, renewable energy source, food production support system, waste management solution, and driver of circular economy policy.

Charlotte shares how the conversation around biogas has changed over the last decade, from asking people to take the industry seriously, to a much more urgent question: how quickly can it scale?

The conversation gets practical:

🔹 Why biogas has moved from a niche technology to a recognised global climate and energy solution
🔹 How WBA has helped raise the profile of biogas with governments, investors and international organisations
🔹 Why visibility and fragmentation were two of the biggest problems the industry needed to solve
🔹 What different countries and markets can learn from each other as the sector grows
🔹 Why policy certainty, permitting, skilled people, public understanding and digestate still matter everywhere
🔹 Why the next decade is not about proving biogas belongs in the conversation, but scaling it fast enough

It’s a strong listen for anyone working in biogas, RNG, energy, policy, climate, waste, agriculture, or infrastructure and anyone who wants to understand why biogas is becoming part of the global conversation on methane, energy security and circular economy.

This week on RNG Girls, Lisa Kitt and Skye Austin are joined by Bryan Sievers and Bernie Sheff for a post-Biogas Americas conversation on where the biogas and RNG industry really is right now.

Bryan is a farmer, RNG developer, policy advocate, and a leading voice in rural agriculture and DC. Bernie recently wrapped his time as Chair of the American Biogas Council after helping lead the organisation through 14 years of growth and industry evolution, and is now stepping into the Chair of the United Biogas Alliance.

Together, they reflect on the energy coming out of Biogas Americas, why the event felt less like “gold rush” growth and more like operational maturity, and what the conversations on the floor revealed about the next phase of the market.

The discussion gets into the harder, more practical questions now facing the industry: operational discipline, financing, offtake, PFAS, electricity, data centres, distributed energy, marine fuels, and the need to keep widening the “big tent” for biogas.

Bernie also shares why the next phase is about expanding offtake and widening the opportunity, from small landfills, dairies, hog farms and poultry facilities to marine fuels, electricity, fertiliser, air quality and water protection. His view is clear: the industry is still building its foundation, but the demand is coming.

Key takeaways

🔹 Why Biogas Americas felt like a pulse check for an industry moving into maturity
🔹 How operational discipline, financing, offtake and resilience are shaping the next phase
🔹 Why electricity is coming back into the conversation, especially around data centres, grid reliability and energy security
🔹 Why smaller opportunities, landfills, dairies, hog farms and poultry facilities could matter more than people realise
🔹 Why marine offtake and a global RNG price point could change the scale of the industry
🔹 What the American Biogas Council needs to become as the industry grows into a connected “big tent”

It’s a strong listen for anyone tracking where biogas and renewable natural gas go next, beyond the headlines, beyond the hype and into the harder conversations that will shape long-term trust, delivery and scale.

RNG Girls is a podcast on the people, projects and politics of Renewable Natural Gas.

Bold voices with real impact are powering the future of biogas and women are leading the charge.

In this special live episode recorded at the Women in Biogas & RNG Luncheon (presented by DTE Energy), RNG Girls hosts Lisa Kitt and Skye Austin are joined by Cyn S. French, MacKenzie Bernhard, and Christie Ings, P. Eng. for an honest conversation about what it takes to build a career and stay in it, in a fast-moving, often male-dominated industry.

The room was full of connection and community, but the discussion stayed grounded: discipline, resilience, self-care, real support, and the leadership habits that matter when the market feels uncertain.

Key takeaways

🔹 Why “mental strength and discipline” are leadership strategies, not optional extras

🔹 The role of team, time-management, and showing up for others (especially when you’re on the road)

🔹 Why emotional self-care matters, and why being human doesn’t make you less credible

🔹 What real support looks like (and the behaviours that build trust when someone isn’t in the room)

This week on RNG Girls, Lisa Kitt and Skye Austin sit down with Paul Greene, an advisor to the biogas and RNG industry with a robust 30-year career across the water, wastewater, energy, and environmental industries, for a true “Biogas 101” conversation (no background required).

Paul shares how he found his way into biogas through water and wastewater, project delivery, development, and project finance, before becoming a founding member of the American Biogas Council and building a national view of what makes projects succeed (and what makes them struggle).

We also talk about Biogas TV and why video storytelling has become such a powerful way to make the industry more understandable, not just in the US, but globally.

From there, the episode gets practical: what biogas actually is, why digesters are “living systems,” how landfill gas differs from digester gas, and why the industry still has work to do around perception, safety, and project timelines.

Key takeaways

🔹 Biogas explained simply: waste in → methane + CO₂ out, with energy and fertiliser benefits

🔹 Why digesters behave like living systems (and why overfeeding/underfeeding matters)

🔹 Digesters vs landfill gas: efficiency, methane concentration, and why cleanup differs

🔹 The biggest misconception: the “odor/ick factor” and what being a “good neighbour” really means

🔹 Giants of Biogas: why the industry should celebrate the people driving it forward
