Abstract:

If global warming is to be avoided, the world must accelerate the transition to net-zero emissions. The pathway for decarbonization of electricity can replace fossil fuels in many segments of economic activity while, at the same time, electricity itself is undergoing decarbonization, facilitating the transition to net-zero. Green hydrogen, or hydrogen produced from renewable sources, has the potential to help decarbonize other difficult-to-decarbonize industrial sectors that aren't receptive to electrification. Green hydrogen is more expensive than electricity because it is made from renewable energy. As a result, it has the potential to be used in situations when electricity cannot replace fossil fuels.
