The Scottish Government’s Farm Advisory Service (FAS) recently held a workshop on opportunities in hydrogen from farm renewables in Aberdeenshire. While wind and solar electricity have been among the most popular technologies for the production of renewable energy, speakers at the event believe that hydrogen is set to become more mainstream – with land one of the main resources required to produce the fuel.

Hydrogen is the most abundant element in the universe and it is highly combustible. The majority of the current industrial production of hydrogen involves reforming hydrocarbon fuels, such as natural gas. But hydrogen can also be produced by electrolysis of water and in cases where renewable electricity is used for this process, the resulting “green hydrogen” is carbon-free.
