The Hydrogen Economy

Hawaii Integrated Biofuels Research Program: Final Subcontract Report, Phase III

“…Also, hydrogen has the highest utilization diversity and can be used in every application where fossil fuels are used nowadays, including domestic heating, automotive and air transportation, powering industry, and electricity generation (Veziroglu, 1990;Johnson, 1975;Gregory, 1973).…”

The kinetics of the reverse deacon reaction

“…In the recent years the concept of a "Hydrogen Economy" has been introduced (32,44,62). The use of hydrogen plays an important role in our present economy and has the potential to play a major role in the future.…”

“…The major problems involved in using hydrogen as a common fuel are storage and transportation. Storage is possible as a gas under pressure, or as a cryogenic liquid or as a metal hydride (44,54).…”

“…However, it has been reported that the exhaust from an internal combustion engine running on the hydrogen-air system contained 220 ppm of HgOg (45). It can be used for supersonic airplanes (61), for ordinary boilers and for household appliances (44). Burned with pure oxygen, the only product is water (HgO) , and there is no pollutant at all; and therefore, is attractive for produc tion of electricity from fuel cells (83).…”

Protons and the hydrogen economy

“…The idea of the hydrogen energy economy is almost 100 years old 8 and is based on the calculation that transporting energy as H 2 gas 2 n mRS eneRgy & SUSTAInABIlITy // V O L U M E 4 // e 1 4 // www.mrs.org/energy-sustainability-journal through pipes is less costly than by electricity running through electric cables. 9,10 Artificial photosynthesis for the production of solar fuels, inspired by Ciamician over 100 years ago, 11 took center stage in the early 1970s in response to the first Arab Oil Crisis. 12 The interest in solar fuels faded away when oil prices came down again.…”
