6. What is the Hydrogen Economy?
This is a term coined decades ago to promote the use of hydrogen as the primary energy carrier for the entire economy: transportation, industrial, and home applications. The term encompasses the production, storage, transportation, and use of this versatile resource.
The hydrogen economy is a
The hydrogen economy is a proposal for the distribution of energy using hydrogen. Hydrogen (H2) releases energy when it is combined with oxygen; however in practice, production of hydrogen from water requires more energy than is released when the hydrogen is used as fuel. Free hydrogen does not occur naturally, and thus it must be generated by electrolysis of water or another method. A reduction in carbon dioxide emission connected with hydrogen fuel is directly achieved only if the energy used to make hydrogen is obtained from non carbon-based sources. Nowadays (2009) the majority of hydrogen produced on earth comes from fossil fuels.
