'Green hydrogen' could be used to power Ireland's islands 

Irish researchers will take part in a major European project aimed at bringing so-called "green hydrogen" into the renewable energy mainstream, including powering the likes of Valentia and the Aran Islands.

Green hydrogen is described as producing energy through the electrolysis of water, while eliminating emissions by using renewable energy. Its supporters say it could completely revolutionise clean energy, while its detractors say it is too cumbersome to achieve on a mass scale.
