The U.S. Department of energy funds projects to convert nuclear energy into clean hydrogen energy

the project will be led by PNW hydrogen LLC and will establish a hydrogen production facility at the Palo Verde nuclear power plant site in Phoenix, Arizona. There will be enough storage tanks on site to hold 6 tons of hydrogen, equivalent to about 200mwh of energy. When the demand is large, it can be converted into electricity and input into the power grid

hydrogen will also be “used to make chemicals and other fuels”, and the project will explore how nuclear power plants export and sell excess energy as an additional source of income. In the future renewable energy based energy ecosystem, benchmark power suppliers such as nuclear power plants are needed only in the absence of sunlight or wind. Therefore, hydrogen production may be a beneficial way to take advantage of its downtime

this is part of the U.S. Department of energy’s “hydrogen shot” goal, that is, to reduce the price of green hydrogen from about $5 per kilogram to $1 per kilogram within ten years. How does the use of expensive nuclear energy, rather than much cheaper solar energy, to produce hydrogen help this goal? If the use of hydrogen energy as a liquid grid battery is economically feasible or even almost feasible for the power station, the excess hydrogen gas flow can be sold cheaply once the main tank is filled. The project will test the economics of the idea
