Hydrogen

As long as hydrogen production relies heavily on fossil fuels, the policy will distract South Korea from its 2050 carbon neutrality strategy and end up emitting enormous additional greenhouse gases. To keep the net-zero pledge on track, South Korea should adopt a renewable-energy based hydrogen scheme by drastically cutting down its reliance on fossil fuels.

Nearly every country has enough solar and wind to generate its required energy. Pumped hydro makes large-scale energy storage a solved problem. Australia is a global pathfinder in solar photovoltaics. Clean hydrogen, imported from Australia, is frequently touted as a major player in the decarbonization of East Asia’s industrialized countries such as Japan and South Korea. But some of the proposed export markets for hydrogen energy are largely illusory, argues Australian National University engineering professor Andrew Blakers.
