A ''hydrogen economy'' is an essential secondary energy economy to realizing a majority renewable energy society. Early implementation of green hydrogen will be in the current chemical synthesis market.
In this commentary, a panoramic view of research, development, demonstration, and deployment needs for production, transportation, storage, and use of hydrogen in United States is discussed, accompanied by key policy recommendations to create a hydrogen economy.
Hydrogen is a clean-burning molecule that could become a zero-carbon substitute for fossil fuels in hard-to-abate sectors of the economy. The cost of producing hydrogen from renewables is primed to fall, but demand needs to be created to drive down costs, and a wide range of delivery infrastructure needs to be built.
Hydrogen is mostly used for oil refining and chemical production. This hydrogen is currently produced from fossil fuels, with significant associated CO2 emissions.
Hydrogen produced from fossil fuels is a versatile energy carrier and can play an important role in a transition to a low-carbon economy. Hydrogen (H 2) is the simplest and most abundant element in the universe, and it only occurs naturally on Earth when combined with other elements.
Introduction. A future economy using hydrogen as an energy carrier1 and fuel has been a topic among policymakers evaluating whether hydrogen could offer an alternative to the prevalent combustion of fossil fuels now
The Future of Hydrogen provides an extensive and independent survey of hydrogen that lays out where things stand now; the ways in which hydrogen can help to achieve a clean, secure and affordable energy future;
Although hydrogen will likely play a role, the real question is just how big a role will it assume. Delivering a hydrogen economy relies upon four interdependent elements: demand, production, storage, and distribution, and every link in this value chain needs to be developed and scaled coherently.
The price of renewable energy must decrease to make green hydrogen competitive, new distribution networks, refuelling stations and transport pathways must be developed to carry hydrogen to the nal destination; and equipment and. infrastructure must be
Hydrogen is an indirect climate gas which induces perturbations of methane, ozone, and stratospheric water vapour, three potent greenhouse gases.
