How should policymakers balance decarbonization, affordability, and energy security in the energy transition?
Energy policy cannot focus solely on decarbonization—it must navigate the trilemma of decarbonization, affordability, and supply security simultaneously. Rather than rushing to decommission existing gas infrastructure, policymakers should leverage world-class gas networks in partnership with electrical systems to deliver the best outcomes for customers across all three priorities.
Why the energy transition is not simply about emissions
The conversation around energy policy often emphasizes decarbonization as the primary goal, but James Earl stresses that this framing misses two equally critical dimensions. Affordability matters because energy is fundamental infrastructure—unaffordable energy undermines economic stability and public support for the transition. Supply security is equally non-negotiable: gas networks already achieve 99.9999% reliability, with interruptions expected only once every 40 years, and they are engineered to the 1 in 20 resilience standard, meaning they can withstand the coldest weather conditions expected in any 20-year period.
This reliability is not incidental—it is by design. Cold weather and peak demand are precisely the scenarios that gas infrastructure was built to handle. As James Earl explains in the episode, gas networks are not a temporary safety net but have a fundamental role to play in power generation when renewables output is low and in industry requiring high-temperature processes.
The case for integration, not replacement
The core insight is strategic: partnership between gas and electrical infrastructure delivers better outcomes than choosing one over the other. Rather than viewing the two networks as competitors or assuming one must eventually disappear, policymakers should design the energy transition to use both systems where they add the most value.
This approach has immediate practical benefits. Data centers, for instance, are increasingly connecting to gas networks because they face electricity connection wait times of up to 15 years—a timeline that defeats the purpose of infrastructure investment. Gas networks, by contrast, offer capacity and speed. Similarly, industries with sustained high-temperature heat demand cannot realistically be powered by electricity alone in the near term. A balanced policy framework would recognize these constraints and build strategy around them rather than against them.
"It has a fundamental role to play across a lot of different end uses, whether that be in power generation when renewables output is low, or in industry that need really high temperature processes."

James runs the membership organisation representing the UK's national gas transmission company and four gas distribution networks in Great Britain, as well as Northern Irish Gas Networks. With expertise spanning both gas and electricity sectors, he brings deep insight into how the two energy vectors can integrate in future systems.
The conversation about gas decommissioning often starts from the wrong place. As discussed in the podcast, the industry has not yet reached a point where decommissioning is the logical next step. Instead, the conversation should focus on how to optimize existing infrastructure and introduce new energy vectors—including green gases—into established networks.
Green gases expand the solution space
Notably, the energy transition is not limited to fossil gas. James Earl emphasizes the distinction between "gas" and "gases"—a shift in language that reflects a shift in strategy. Biomethane and other green gases are already entering the grid today, currently representing about 1% of gas use. These renewable alternatives could meet between a fifth and a sixth of current gas demand in the future, providing a decarbonization pathway that does not require wholesale network replacement.
This is significant because it means existing gas infrastructure can serve decarbonization goals without requiring the enormous capital investment and timeline disruption that wholesale electrification would entail. The episode explores how green gases fit into this broader energy strategy, illustrating that the trilemma can be solved by expanding the toolkit rather than narrowing it.
Key takeaways
- Energy policy must satisfy three competing priorities simultaneously: decarbonization, affordable energy, and secure supply—not prioritize one at the expense of others.
- Gas networks achieve extraordinary reliability (99.9999%) and are engineered for peak demand and extreme weather, making them integral to system resilience.
- Partnership between gas and electrical infrastructure delivers better outcomes than replacement; each system excels in different scenarios and geographies.
- Green gases like biomethane can meet significant future demand (potentially a fifth to a sixth of current use) while keeping existing networks in service.
- Connection timelines matter: electricity infrastructure faces 15-year wait times in some cases, while gas networks offer immediate alternative capacity.

What is the current status of gas network decommissioning in the UK?
James Earl emphasizes that the starting point for the conversation about getting rid of gas and decommissioning is not where the industry is at the moment. The focus should be on how existing gas infrastructure can partner with electrical systems to deliver the best outcomes.
Why are data centers increasingly connecting to gas networks instead of waiting for electricity connections?
Data centers are looking at the gas network because they are being quoted up to 15 years for electricity infrastructure connections, which simply doesn't support their operational timelines. Gas networks offer immediate alternative connectivity.
How can green gases like biomethane complement renewable electricity in future energy systems?
According to James Earl, biomethane is already in the grid today at about 1% of gas use, and could potentially meet between a fifth or a sixth of current gas demand in the future, providing a renewable alternative to fossil fuels.
