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.

Are gas companies marking their own homework?
Yes, yes they are.

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

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.

If Ed Miliband really has decided against zonal pricing, he has just cost Labour 100 seats at the next election. Zonal could be introduced by 2028 and would instantly stop natgas setting wholesale power prices across the UK 96% of the time. Should be a no-brainer.
