What to do with Mossmorran? The answer is obvious but there is no one in Scotland with the vision or drive to understand and act on the obvious. 
From Flares to Fuel: Why Mossmorran Could Become Scotland’s Power-to-Gas Flagship
For decades, Mossmorran has been a byword for heavy industry. The vast gas and petrochemical complex in Fife has powered parts of the Scottish economy, but it has also become one of the country’s most controversial industrial sites — associated in the public mind with flaring, emissions, and a fossil-fuel past that no longer fits comfortably with Scotland’s climate ambitions.
Now, with parts of the complex winding down and hundreds of skilled jobs already lost, a serious question faces policymakers, industry and the local community: what comes next?
One compelling answer is bold rather than timid — the development of a very large Sabatier reactor, turning Mossmorran into a centre for carbon recycling and renewable energy storage.
Turning CO₂ from liability into asset
At its simplest, a Sabatier reactor combines carbon dioxide with hydrogen to produce methane and water. The chemistry has been known for over a century and is robust enough to be used on spacecraft. What has changed is scale and context.
In a modern, industrial setting, the process allows captured CO₂ to be converted into synthetic methane using hydrogen made from renewable electricity. Instead of venting carbon into the atmosphere, emissions become a feedstock. Instead of wasting excess wind power, electricity is stored in the form of gas.
Mossmorran is uniquely well-placed for this transition. It already handles large volumes of gas, already connects to the national gas grid, and already has the utilities, land and planning footprint that new low-carbon industries struggle to secure elsewhere.
A natural fit for Scotland’s energy system
Scotland’s renewable energy success is, increasingly, also a systems challenge. On windy days, turbines generate more electricity than the grid can absorb. Curtailment — paying wind farms to switch off — is becoming routine.
A large-scale Sabatier reactor would turn that problem into an opportunity. Surplus electricity would be used to produce green hydrogen, which would then react with captured CO₂ to create synthetic natural gas. That gas could be injected straight into existing pipelines, stored seasonally, or used by industry and power stations when renewable output drops.
Unlike batteries, methane storage works at national scale and over months, not hours.
Re-using infrastructure, not abandoning it
One of Mossmorran’s biggest strengths is also its greatest political advantage: this would not be a greenfield development. The site already hosts compressors, pipelines, grid connections, safety systems and an experienced workforce. Repurposing that infrastructure is cheaper, faster and more socially responsible than letting it rust while new facilities are built elsewhere.
Crucially, it offers a pathway for industrial workers to transition, rather than be displaced. The skills needed to operate high-temperature reactors, manage gas flows and maintain process safety are already present in Fife.
From controversy to leadership
Mossmorran’s environmental record has long strained community relations. A visible commitment to carbon capture and reuse would not erase that history, but it would signal a clear change of direction.
Instead of being known as one of Scotland’s largest emitters, the site could become a national demonstration of how heavy industry decarbonises without disappearing. Countries across Europe are racing to build power-to-gas plants at the 100–200 megawatt scale. Scotland has the renewable resources, the policy ambition — and at Mossmorran, the perfect industrial host.
A choice about the future
Doing nothing is still a decision. It risks leaving Mossmorran as a symbol of industrial decline, with lost jobs and stranded assets.
Choosing a large Sabatier reactor would be different. It would be a statement that Scotland intends not just to shut down high-carbon infrastructure, but to transform it — using science, engineering and existing communities as part of the solution.
From flares to fuel, Mossmorran could once again sit at the heart of Scotland’s energy story — this time pointing firmly toward net zero.
