A small town in central Utah is set to be the home of a new underground “battery” that will store hydrogen as a clean energy source.
According to The New York Times, developers are creating two caverns as deep as the Empire State Building is tall from a geological salt formation near Delta, Utah. These caverns, which are expected to be complete next year, will be able to store hydrogen gas.
The hydrogen will be produced nearby through a process called electrolysis. This will be done using excess solar and wind power in spring and fall, when demand for energy is low. Then it can be stored until peak energy demand hits in the summer — at that time, it would be burned at a power plant as a blend of hydrogen and natural gas.
