Electricity is key to decarbonise most sectors of the economy. But, for some of them, such as aviation and maritime transport, electricity alone will not be appropriate. For those, new energy solutions – based on low-carbon electricity, low-carbon hydrogen, carbon dioxide (CO2) and careful use of biomass – must be developed.
While hopes remain high that the evolving hydrogen economy will eventually lead to a point at which hydrogen fuelled vehicles and aircraft will one day be common, there are those who believe it is more.
