WebMar 16, 2024 · Green hydrogen is also incredibly challenging and expensive to store and transport. It is a highly flammable gas with a low volumetric density, requiring investment in specialized pipelines and carriers. 3. High energy losses. Green hydrogen loses a considerable amount of energy at every point in the supply chain. WebOnce purified, the methane reacts with steam to form a synthesis gas containing carbon monoxide (CO) and hydrogen (H2). Then, the water vapor reacts with the carbon monoxide of the synthesis gas to form carbon dioxide (CO2) and more hydrogen. This blend, rich in CO2 and H2 , is then purified to obtain about 99.9% hydrogen. WebJan 20, 2024 · Hydrogen fuel cells produce electricity by combining hydrogen and oxygen atoms. The hydrogen reacts with oxygen across an electrochemical cell similar to that of a battery to produce electricity, water, and small amounts of heat. ... and companies won't build refueling stations if they don't have customers with hydrogen-fueled vehicles.
