Developers in the United States are planning a significant shift towards expanding hydrogen production using electrolysis technology, departing from conventional methods like steam methane reforming (SMR) that contribute to carbon emissions. The U.S. Energy Information Administration projects a potential surge in the country's hydrogen production capacity from 116 MW to 4,524 MW annually, generating around 0.72 million metric tons of hydrogen via electrolysis. This move towards electrolyzers is part of a broader energy transition to cleaner and sustainable practices. While current hydrogen production heavily relies on SMR from natural gas and coal, efforts are being made to reduce carbon emissions through carbon capture and storage (CCS), giving rise to 'blue hydrogen.' The article also highlights the critical role of hydrogen in industries like petroleum refining and fertilizer production, as well as its potential application as a fuel for power generation. Challenges exist in blending hydrogen with natural gas in power plants, signaling the need for technological advancements. It stresses the importance of sourcing electricity for electrolysis from renewable or clean energy sources to ensure the carbon-neutrality of hydrogen production. The International Energy Agency (IEA) notes the commercial deployment of two electrolyzer technologies, PEM and Alkaline, which require further development to enhance competitiveness and efficiency.
