Wales as a country can lay claim to a special place in the hydrogen economy, with the fuel cell being invented in 1842 by none other than William Grove of Swansea. Sir William (as he became known) may have been underwhelmed by our reliance on coal, oil and gas over the past 180 years - and he would also probably have to accept that the 2050 picture of a decarbonised economy is likely to be composed of a blend of energies working in harmony to meet the many needs of individuals, communities, industries and infrastructures. But, on thing is sure, low carbon Hydrogen will undoubtedly be a significant feature in that picture, as its potential for reducing Green House Gas emissions is increasingly being recognised by Governments around the world; and it’s already being mooted as a key pillar in the Welsh Government’s Low Carbon Delivery Plan (LCDP) due to be unveiled in November 2021.
