If the gas networks still can't contain methane after more than a century of practice, why should we trust them with hydrogen?
Keeping a congregation warm with a heat pump carries more social proof than any editorial can ever muster.

China is now the leading clean energy powerhouse with the West falling behind.
The transition is inevitable; the key question is where and how fast it happens.
I look forward to discussing this in Davos next week at the World Economic Forum, facilitating a live-streamed session on electrostates.

My fav part of London's New Year's Eve 2026 celebration was the scene with The Lionesses 👏

"Caribbean barbers with the sharpest trims
Christian neighbours saying happy Hannukah mate
And Muslim mums saying merry Christmas love"

I've found that gas engineers are always friendly and happy to chat.
The leak is coming from a 10 inch cast iron main. His words: "It stinks!"
SGN have apparently visited this road many times (pointing to the various new bits of tarmac all over the shared path).

This is one of the reasons hydrogen won’t be piped simply through existing gas lines, despite what fossil gas companies claim. Hydrogen behaves very differently — it can leak through solid metal

I've put a "what are you using this for?" form on the site.
Do people fill it in? No. Rude.

Energy companies injected green hydrogen into Britain's gas grid and generated electricity - a "landmark development for the UK's climate ambitions."
So we can just use blended hydrogen to power our old gas turbines? Problem solved?
Not quite.

In the plots below, I've summed up the total HDD for each year. I've then compared some 30 years periods (1940 to 1969 and 1995 to 2024). It's not just a little bit warmer in the winter. It's significantly wamer.

More evidence of gas leaks at Seabank Power Station
Why is £22bn of taxpayers' money being allocated to carbon capture when methane leaks are clearly not under control at our power stations?

In 2005 I spent 5 months in Ecuador investigating oil extraction.
Around then German bank WestLB funded a new Andes pipeline despite past spills.
What I saw was shocking and mostly unseen. This 2022 video shows just one example of repeated spills poisoning rivers and communities.

Read the correspondence on my FOI between the Environment Agency and seabank power station, you'll see that nothing happens. There's a collective shrug and things continue as they were.
GHGSat is a private company; they need revenue to pay for those satellites

Yet another(!) is GHGSat but unlike the others this is a commercial start-up founded in 2011. It flies a fleet of greenhouse gas-detecting satellites, including ones mapping methane. The European Space Agency and the UK Space Agency both buy data from them to make available to researchers e.g.

This is a methane plume detected over a seabank power station. I had to extract this image via a freedom of information request.
Fossil fuel companies will tell you that they can safely bury carbon dioxide from burning gas. How? They're not even handling methane competently.

Here's a church getting a heat pump.
This is my local church. I was married here. The graveyard is filled with names that I know. One day I'll probably join them.
Until then, I'll work on decarbonisation.

Do some reading on "leveraged buyouts and UK national infrastructure".
It's absolutely maddening.
Private equity has managed to turn the water and gas networks into interest-only buy to lets, and we're all paying the bills... financially and environmentally.
