Sustainable Energy Transition for Renewable and Low Carbon Grid ... frontiersin.org Mar 23, 2022 3 facts
procedureElectrolysis uses electricity to split water molecules into hydrogen fuel.
claimHydrogen production is achieved through electrolysis and steam methane reforming.
claimElectrolysis is more expensive than methane reforming, and for sustainability, the electricity used must come from green sources, which remains a challenge in many parts of the world.
Hydrogen in Oil and Gas: Decarbonizing the Industry Through ... - JPT jpt.spe.org Oct 10, 2025 2 facts
claimElectrolysis using renewable electricity, including PEM, alkaline, and SOEC technologies, is a scalable and environmentally friendly method for hydrogen production, though it is energy-intensive and more expensive than other production methods.
claimCombining offshore wind with electrolysis on oil and gas platforms allows for offshore hydrogen production while avoiding grid constraints.
Impact of carbon dioxide removal technologies on deep ... - Nature nature.com Jun 17, 2021 2 facts
measurementThe REGEN model assumes electrolysis capital costs of $200/kW, which represents the lower range of current estimates.
claimThe 100% CO2 cap case without Carbon Dioxide Removal (CDR) results in net energy storage losses that are over an order of magnitude higher than the electricity use of Direct Air Capture (DAC) in the 100% DAC Only case, because gas turbines are replaced with hydrogen and electrolysis, which have low roundtrip efficiencies.

claimResearch using the Sifre tool demonstrated that regional urban design can benefit from technologies like biofuel generation, fuel cells, and electrolysis to achieve sustainability goals.
Hydrogen Energy Storage Market to Reach USD ... - PR Newswire prnewswire.com Mar 25, 2026 1 fact
claimHydrogen energy storage balances intermittent renewable energy sources like solar and wind by converting excess electricity generated during peak production into hydrogen through electrolysis for later use, which enables grid stabilization and long-duration energy storage.
Advancing energy efficiency: innovative technologies and strategic ... oaepublish.com 1 fact
claimGreen hydrogen is produced through electrolysis, which uses renewable energy sources to split water into hydrogen and oxygen, and can be used in fuel cells as a clean substitute for fossil fuels in industrial processes, transportation, and heating.
Hydrogen Can Immediately Reduce Emissions for Heavy Industry rmi.org Jan 28, 2020 1 fact
claimIn developed economies with less CO2-intensive power grids, such as the European Union and the United States, hydrogen produced through electrolysis can immediately begin decarbonizing the steel industry.
