Hydrogen could play a central role in helping the world reach net-zero emissions by 2050. As a complement to other technologies, including renewable power and biofuels, hydrogen has the potential to decarbonize industries including steel, petrochemicals, fertilizers, heavy-duty mobility (on and off-road), maritime shipping, and aviation, as well as to support flexible power generation (among other applications). In 2050, hydrogen could contribute more than 20 percent of annual global emissions reductions.
