21st Century’s energy: Hydrogen energy system

Energy Conversion and Management, 2008
Fossil fuels (i.e., petroleum, natural gas and coal), which meet most of the world's energy demand today, are being depleted fast. Also, their combustion products are causing the global problems, such as the greenhouse effect, ozone layer depletion, acid rains and pollution, which are posing great danger for our environment and eventually for the life ...

Hydrogen as an energy carrier: scenarios for future use of hydrogen in the Danish energy system

International Journal of Hydrogen Energy, 2004
Scenarios for a transition to a hydrogen society are constructed for Denmark. The physical basis for the scenarios is the exploitation of renewable energy resources already in progress in Denmark. Hydrogen is proposed as a convenient energy carrier due to its versatility in use, transmission and as an energy storage medium.

Hydrogen: the future energy carrier

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010
Since the beginning of the twenty-first century the limitations of the fossil age with regard to the continuing growth of energy demand, the peaking mining rate of oil, the growing impact of CO 2 emissions on the environment and the dependency of the economy in the industrialized world on the

The energy of hydrogen in zirconium–rhodium

Physica Status Solidi (a), 1979
Calculations previously made for α-zirconium are extended to determine how the introduction of rhodium into zirconium affects the energy of absorbed interstitial hydrogen. The predicted change in energy of 0.05 Ryd on alloying is in reasonable agreement with the estimated experimental result.

The hydrogen/hydride energy concept

International Journal of Hydrogen Energy, 1978
Abstract With technology at its present stage, hydrogen is a very convenient secondary energy source (fuel, propellant) at the end of the oil era, as hydrogen (given the necessary primary energy, e.g. coal, nuclear energy for hydrogen production) is available in water in practically inexhaustible quantities and its distribution in the form of pure ...

The fusion-hydrogen energy system

Applied Energy, 1994
Abstract This paper will describe the structure of the system, from energy generation and hydrogen production through distribution to the end users. It will show how stationary energy users will convert to hydrogen and will outline ancillary uses of hydrogen to aid in reducing other forms of pollution.

Hydrogen energy

2002
Kao ekološki čisto gorivo vodik se izvrsno nadopunjuje s obnovljivim izvorima energije i omogućuje njihovo šire korištenje. Mogućnost skladištenja riješava problem stohastičke prirode energije sunca i vjetra. Vodik se iz obnovljivih izvora energije može proizvesti elektrolizom vode ili iz biomase.
