As pressure to find alternatives to climate-harming fossil fuels increase, hydrogen is emerging as a potential source to decarbonize everything from electricity production to transportation.
Advancement in technologies that make it possible to produce hydrogen with zero or little greenhouse gas emissions is fueling much of its popularity, along with help from some hefty U.S. government subsidies and investments. The U.S. Department of Energy (DOE) also recently set national goals to increase annual “clean hydrogen” production from nearly zero to 10 million metric tons by 2030; and to 50 million metric tons by 2050.
