A hydrogen fuel cell power plant is a type of fuel cell power plant (or station) which uses a hydrogen fuel cell to generate electricity for the power grid. They are larger in scale than backup generators such as the Bloom Energy Server and can be up to 60% efficient in converting hydrogen to electricity. There is little to no nitrous oxide produced in the fuel cell process, which is produced in the process of a combined cycle hydrogen power plant. If the hydrogen could be produced with electrolysis also known as green hydrogen, then this could be a solution to the energy storage problem of renewable energy.[1][2]
