Five myths of H2 via rmi

ne of the factors constraining global decarbonization is the scarcity and value of renewable electricity, which is used to produce “green” hydrogen. Already the world needs vastly more clean electricity infrastructure, as power consumption in 2050 is expected to double from population and economic growth alone — and only 10 percent of electricity today comes from solar and wind. Add in the electricity required to make green hydrogen to decarbonize heavy industry and transport, and power consumption could triple. Given this backdrop, at a macro level, it is important to prioritize reducing electricity consumption and using renewable electricity most efficiently. As such, many of today’s micro-level business cases of hydrogen for heating buildings, generating power, or fueling light-duty vehicles are better suited for investments in energy efficiency or direct electrification (see Exhibit 1 below). https://rmi.org/five-hydrogen-myths-busted/
