Gas Security Is Energy Security — and Bio-Methane CCHP Is the Missing Half
Sep 28, 2026 · @John C Burke
Britain's gas system is the foundation of its energy security, and policy has been treating it as a problem to retire rather than an asset to secure. That is the core finding of Gas Security: The Foundation of Energy Security, published in September 2026 by Kathryn Porter of the independent consultancy Watt-Logic. [Download her Full Report HERE]
For readers of Sun Earth Energy, the report is welcome confirmation of arguments we have made for over a decade. Porter supplies the market diagnosis. This article sets out the prescription her report leaves out: bio-methane in the gas grid, burned in high-efficiency combined cooling, heat and power (CCHP), inside an integrated urban energy system.
The two halves belong together. Her work shows why the gas network must be kept strong. Ours shows how to make it domestic, renewable and far more efficient.
The diagnosis: what Porter's report finds
Porter's central finding is that gas's role is more enduring, and the gas system more fragile, than current policy assumes. Her evidence falls into six points.
- Electricity is only part of the story. Even fully decarbonised, electricity meets only about a fifth of UK final energy demand. Space heating and industrial process heat remain on gas for decades.
- The heat-pump arithmetic does not work on current timescales. Around 23–24 million homes use gas boilers. The UK installed about 105,000 heat pumps in 2025, a record year. Even at the reduced target of 450,000 a year, replacing the boiler stock would take around 50 years.
- Networks, not gas, are now driving bills up. Wholesale and network costs have both roughly doubled since 2017. Constraint payments more than trebled to £1.9 billion in 2025–26, and the National Audit Office has criticised the Connect & Manage approach.
- The North Sea could fall off a cliff, not a slope. Offshore pipelines such as CATS, SAGE and FLAGS need a minimum throughput to stay viable. The 2018 Theddlethorpe closure stranded 22 Southern North Sea fields at once.
- Storage is thin. Britain holds around sixteen days of gas demand in storage, and the future of Rough still awaits a funding decision.
- Imports are not guaranteed under stress. Norwegian reservoirs are at twenty-year lows, the French nuclear fleet is ageing, and cold, still weather tends to hit Britain and its neighbours at the same time.
Her recommendations follow: fix the misunderstanding of how gas is priced, raise domestic production, cut reliance on electricity imports, model gas and electricity together, focus on cheap energy, and treat energy security as national security.
RCP8.5 as Implausibility Sinks In

The fallout from the recent Intergovernmental Panel on Climate Change (IPCC) ruling that computer model high emissions pathway RCP8.5 is “implausible” is only just beginning. Most mainstream media fearmongering stories over the last 15 years need to be moved into the junk file, as do the increasingly shrill sandwich-board pronouncements of King Charles and Sir David Attenborough. But the rot goes much deeper than ill-informed public comment, although that alone has been enormously influential in promoting the Net Zero fantasy. Activist-ridden science bodies such as the UK Met Office have brazenly used RCP8.5 to flam up weather predictions which in turn has led to onerous requirements being placed on British industry and finance. Politicians have been convinced by patently ridiculous claims and Net Zero rules and regulations have cascaded through the economy and society.
All the politicised predictions need to be junked and all the resulting regulations reconsidered with a view to abolition. They are all based on assumptions that many at the time said were ridiculous and have now been officially marked as not wanted on voyage. Those inclined to be uncharitable might suggest it was all a hoax from start to finish.

Scotland's Looming Energy Crisis — Key Points
1. The "electricity superpower" myth Porter opens by challenging the popular notion that Scotland is an energy superpower. In reality, Scotland's grid is held together by just two power stations — Torness (nuclear) and Peterhead (gas) — and the National Energy System Operator (NESO) will not allow both to go offline simultaneously for maintenance.
2. How electricity grids actually work She gives a detailed explanation of why grid stability is a physics problem, not a political one. Conventional power stations maintain grid frequency (50 Hz) and voltage through natural electromagnetic "inertia" — they resist fluctuations automatically. Wind and solar, by contrast, use inverters that are "grid following": they need a stable grid to operate and cannot form or stabilise one themselves.
3. Why batteries and renewables cannot fully replace conventional generation Batteries and inverter-based technologies can provide some support services, but only through complex, expensive control systems — not naturally. Grid-forming inverters remain experimental, with none proven at operational scale anywhere in the world.
4. The Iberian blackout of April 2025 Porter argues clearly that this blackout — which cost 11 lives and caused an estimated 165 excess deaths — was caused by renewables. A cascade failure began with a faulty solar inverter, was worsened by wind and solar generators failing to meet grid code obligations during a frequency drop, and resulted in the entire grid collapsing within seconds. She uses this as a direct warning for Scotland.
5. Scotland's specific vulnerability Scotland already experiences voltage control issues and sub-synchronous frequency oscillations since the premature closure of Longannet coal station in 2016. The closure of Torness is scheduled by March 2030–2032, and Peterhead is ageing. With lead times for new gas turbines at 7–8 years, there is a realistic scenario where Scotland has no major conventional generator — a situation she describes as "a recipe for disaster."
6. Geography and transmission challenges Most electricity demand is in England, while most new renewable generation is in northern Scotland. Long transmission distances make voltage control harder, amplifying the need for strategically located synchronous generators.

ADDENDUM: The Energy Policy Dimension:
How the Net Zero and Decarbonisation Agendas Compound the Built Environment Crisis —
and Why Decentralised Bio-Methane CCHP and Urban Integrated Metabolism Represent the Correct Alternative February 2026 | Companion document to: The Deferred Reckoning
Introduction: A Compounding Error
The main report demonstrated that the UK faces an inherited infrastructure maintenance liability of £520bn to over £850bn — the result of generations of political short-termism, deferred maintenance, and misdirected spending. This addendum addresses a further and perhaps more consequential layer of the same problem: that the current energy policy framework, built around Net Zero and Decarbonisation orthodoxy, is now being imposed upon a building stock and infrastructure network for which it is profoundly unsuited.
The consequences are severe. An already creaking built environment is being asked to carry the additional burden of an energy transition designed around assumptions that do not reflect the reality of 30 million ageing buildings, Victorian utility networks, and a construction industry already overwhelmed by the maintenance backlog documented in the main report. The result is not transformation — it is the addition of one very expensive mistake upon another.
The central argument of this addendum: the UK's Net Zero strategy imposes maximum cost and disruption upon minimum-efficiency solutions, whilst ignoring a thermodynamically superior, economically self-funding, and practically deliverable alternative that has been available — and partially operational — for decades.
1. The Built Environment and Net Zero: A Fundamental Mismatch
The UK government's Net Zero strategy for buildings rests on several assumptions, each of which fails to withstand engineering scrutiny when applied to the actual housing and commercial stock described in the main report.
