Stoke-on-Trent is home to a cutting-edge trial attempting to green-up the UK's gas cooking and heating supplies, with the boilers and burners of Keele University now huffing on natural gas that's been cut to include 20 per cent hydrogen.
This is the first trial phase of the UK's HyDeploy scheme, a trial examining the cost and performance vectors of using a blended hydrogen and natural gas mix. It burns just the same, they say, with the burning of hydrogen producing nothing but water as its by-product. And from what we remember about science, there's lot of hydrogen in the universe, so that's good too.
Keele University has its own private gas connection, and with the simple installation* of an electrolyser, a power supply unit, a buffer, pipework and a grid entry unit, it's been switched over to the hydrogen blend. Campaigners hope this puts the UK on course to add hydrogen to the entire natural gas network in the future, with new gas boilers already being sold in hydrogen-ready configurations, pending any future mandated supply switchover.
