The use of „clean hydrogen“ could lower the costs of worldwide decarbonization by 15 to 22 percent, as concluded by a recent study. Researchers achieved this result by further developing the Global Change Analysis Model (GCAM) and analyzing the costs and benefits of deploying hydrogen in 24 scenarios aiming for a climate-neutral energy system by 2050. These scenarios vary in assumptions regarding socio-economic development as well as the availability of hydrogen, batteries, and net-negative technologies (DACCS and BECCS).
