hydrogen economy
1Hydrogen economy — The hydrogen economy is a proposed system of delivering energy using hydrogen. The term hydrogen economy was coined by John Bockris during a talk he gave in 1970 at General Motors (GM) Technical Center.[1] Hydrogen advocates promote hydrogen as… …
2hydrogen economy — noun A hypothetical future economy in which the primary form of stored energy for mobile applications and load balancing is hydrogen (H2), and, in particular, hydrogen replaces fossil fuels in automobiles …
3hydrogen economy — /haɪdrədʒən əˈkɒnəmi/ (say huydruhjuhn uh konuhmee) noun an economy relying on hydrogen rather than carbon fuel, particularly as an energy source for motor vehicles, so as to reduce greenhouse gases …
4Hydrogen storage — describes the methodologies for storing H2 for subsequent use. The methodologies span many approaches, including high pressures and cryogenics, but usually focus on chemical compounds that reversibly release H2 upon heating. Hydrogen storage is a …

6Hydrogen damage — is the generic name given to a large number of metal degradation processes due to interaction with hydrogen.Hydrogen is present practically everywhere, in the atmosphere, several kilometres above the earth and inside the earth. Engineering… …
7Hydrogen production — Hydrogen is commonly produced by extraction from hydrocarbon fossil fuels via a chemical path. Hydrogen may also be extracted from water via biological production in an algae bioreactor, or using electricity (by electrolysis), chemicals (by… …
8Hydrogen embrittlement — (or hydrogen grooving) is the process by which various metals, most importantly high strength steel, become brittle and crack following exposure to hydrogen. Hydrogen cracking can pose an engineering problem especially in the context of a… …
9Hydrogen safety — covers the safe use and handling of hydrogen. Hydrogen poses unique challenges due to its ease of leaking, low energy ignition, wide range of combustible fuel air mixtures, buoyancy, and its ability to embrittle metals that must be accounted for… …
10Hydrogen technologies — are technologies that relate to the production and use of hydrogen. Hydrogen technologies are applicable for many uses.Some hydrogen technologies are carbon neutral and could have a role in preventing climate change and a possible future hydrogen …
