Hydrogen production technology for powering civil and industrial systems: a review
Partial use of alternative energy exemplified by hydrogen energy is expected to reduce negative impacts associated with the current dependence on fossil energy and bring net gain to regional and national economies. Hydrogen has emission levels that are far below the existing and possibly, future standards. Hydrogen energy may enhance energy security and perhaps allay concerns some concerns about ...

Is nuclear power more competitive producing electricity or hydrogen?
Steam methane reforming is the world's dominant hydrogen production technology, using natural gas as both feedstock and fuel, but producing more than 9 kg of CO2 for each kilogram of H2. Natural gas prices between $6 and $8/GJ yield an average hydrogen production cost between $12 and $15/GJ, excluding the cost of CO2. High-temperature gas reactors, e.g. the modular helium reactor, can be ...

Cost-Effective Nitrogen for Electronics Production Using Modern Hydrogen Technology
The Product Quality Can Be Increased by the Self-Generated Nitrogen Nitrogen is needed in the production of electronic assemblies. Nitrogen therefore features in common soldering processes such as selective, wave and reflow soldering. Its use serves to prevent oxidation on printed circuit boards and ensure high-quality soldered connections. Using generators to produce nitrogen on site thus helps ...

A combined graph theory and analytic hierarchy process approach for multicriteria evaluation of hydrogen energy systems
Hydrogen is a renewable energy source and has the potential to mitigate the green house gas effect and to meet the increasing global electricity demand. In the present study, a multicriteria methodology is developed by combining graph theory and analytic hierarchy process methods for the evaluation and selection of hydrogen energy systems. The hydrogen energy system alternatives are assessed ...

Laboratory scale tests of coal-based hydrogen production with CO2 capture in the aspect of clean coal technologies
In the light of continuously increasing oil prices as well as stronger environmental regulations, an important issue becomes finding an alternative to fossil fuels. Scientists agree that hydrogen seems to be an ideal, price-competitive and environment-friendly future energy carrier. One of the most effective methods of hydrogen production is the process of steam gasification of coal to ...

US work on technical and economic aspects of electrolytic, thermochemical, and hybrid processes for hydrogen production at temperatures below 550°C
Hydrogen demand is increasing, but there are few options for affordable hydrogen production free of greenhouse gas emissions. Nuclear power is one of the most promising options. Most research is focused on high-temperature electrolytic and thermochemical processes for nuclear-generated hydrogen, but it will be many years before very high temperature reactors become commercially available. For ...
