UK Gas Plans A Carbon-Free Future With Hydrogen

The title of this post is the same as that of this article on Eco Business.

This is the introductory paragraph.

A mixture of green hydrogen produced by surplus solar and wind power and bio-methane coming from farms and waste food will ensure the British gas industry a carbon-free future in 30 years, according to the country’s gas network operators.

It’s all part of a programme called Gas Goes Green.

It’s all part of a plan for the UK to go carbon-neutral by 2050, which is enshrined in UK law.

But there is competition to a hydrogen gas grid, as this paragraph from the article explains.

This ambitious plan faces some competition from the advocates of ground-source heat pumps as an alternative for heating homes. The pumps have the advantage of running on green electricity, and cut out the need for gas entirely, but they need to be installed in large numbers.

We should use every trick in the engineering locker to avoid generating carbon-dioxide. Ground source heat pumps, are ideal for new build properties.

I used a ground source heat pump for our indoor swimming pool at our house in Debach in the late 1980s. It was no trouble.

  1. Not my experience of GSHP. We have a Nibe at the Eco Lodges in Clophill, and it uses far more electricity that was estimated by the designer of the system. This arises from the typical intermittent demand for hot water, as the heat pump can’t supply peaks and resorts to using large immersion heaters to make good the shortfall. Reliability is another issue, and the first indication that the pump has failed is when a huge electricity bill is received. The latest ASHPs are now much quieter, have a higher CoP, can generate hot water at a higher temperature, and if used with phase change heat stores that can also be fed by PVs or solar panels, then a solution with a higher performance at half the cost can be provided. GSHPs and their large low temperature water storage cisterns take up an enormous amount of space that needs to be added to their initial cost.

    • Did my system, use the heat capacity of the pool creatively? It did also take heat from the boiler in the house!
