Using Electrolyzers to Produce Renewable Hydrogen |
Hydrogen is gaining popularity across the world as a source of clean energy with applications in transportation, stationary power, aviation, shipping, and more. When used as a fuel for a fuel cell system, the only by-products of the reaction are electricity, heat, and water, demonstrating the dramatic potential for emissions reductions across market sectors. In addition to decarbonizing these end-use applications, there is also much work underway to reduce the carbon intensity of hydrogen production itself. These methods include producing hydrogen from biomass or biomethane, as well as using renewable electricity from wind or solar power to power an electrolyzer. Electrolysis is the process of using electricity to split water into its component parts of hydrogen and oxygen. That hydrogen can then be stored for later use as fuel in a fuel cell vehicle, to power a stationary fuel cell system, or for power-to-gas applications. Using hydrogen to store excess power generated from renewables is showing great potential. According to the International Renewable Energy Agency, renewable hydrogen produced from electrolysis is projected to grow rapidly, citing a current growth trend from megawatt to gigawatt scale in Europe.
