Increasing concerns about carbon emissions and the need to decarbonize the industrial, commercial, transport, and power sectors have forced countries to reduce their dependency on fossil fuel-based systems and increase deployment of renewable energy sources (RES). To meet the 1.5-degree Celsius target, global renewable energy capacity should increase from about 2500 GW in 2019 to more than 15,000 GW in 2050, a near 6-fold increase. However, total decarbonization of certain sectors, such as transport and industry, cannot be achieved solely by electrification. This challenge can be addressed by green hydrogen produced through electrolysis from RES, wind and solar, in particular. Green hydrogen produced through electrolysis can then be used downstream as a chemical feedstock material in high-carbon sectors that are difficult to decarbonize through electrification alone.
