Hydrogen production by high temperature electrolysis coupled with an EPR, SFR or HTR: techno-economic study and coupling possibilities
Hydrogen production by high temperature electrolysis coupled with three nuclear reactors (the European pressurised reactor, the sodium-cooled fast reactor and the very high temperature reactor) was studied in terms of perspectives and hydrogen production costs. Firstly, we present the features of producing water steam by using the three nuclear reactors. Secondly, we present the hydrogen ...

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 ...

Reviewing the factors affecting regenerative molten carbonate fuel cells
To evaluate the possibility to use molten carbonate fuel cell technology for high temperature electrolysis, the factors affecting the electrode reactions have been examined by surveying the published literature. The literature results showed that H2, CO2 and CO evolved as cathode off–gases and O2 as anode gas. At low polarisation, the discharge of oxide ions to O2 was the only anodic process; ...

The US Department of Energy research and development programme on hydrogen production using nuclear energy
As part of the Hydrogen Fuel Initiative proposed by President George W. Bush in 2003, the Nuclear Hydrogen Initiative is developing technologies to provide large amounts of hydrogen without pollution or greenhouse gases. The Nuclear Hydrogen Initiative is a research and development programme within the Department of Energy's Office of Nuclear Energy, Science and Technology that is using a series ...

Green hydrogen energy production and its critical importance on clean water
As the global economy starts to fully integrating other sources of energy in addition to fossil fuel, solar and wind, green hydrogen is starting to gain momentum. Global leaders across industry and governmental agencies are developing aspiring and potentially paradigm shifting ways to produce lower carbon energy fuels such as hydrogen. In the interim, other companies are evaluating how hydrogen ...

Key Questions for Analysts of Energy Balances and Other Policy Analyses
Untitled Document The United States imports approximately one third of its energy sources, mostly in the form of petroleum. 1 Heightened interest in finding alternative fuels, and thus reducing the U.S. reliance on imported oil, was reflected in the 2005 Energy Policy Act.2 However, in some cases, the production of alternative fuels may itself require a ...

For the Green Deal, hydrogen also needs to be green
The new European Commission is planning a European Green Deal. The goal is to create the first climate-neutral continent by 2050. This cannot happen without using much more hydrogen than at the moment because hydrogen is a zero-emission fuel when burned with oxygen. However, not all forms of hydrogen are alike. We need to shift from grey hydrogen, the production of which causes CO₂ ...

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 ...

Renewables boom in North Africa Still pending.
In North Africa, the renewables sector has great growth potential, but the market needs to be improved: rules, political stability and depowering the fossil sector. The Benban Solar Park in Egypt is the fifth largest in the world. A pharaonic project, so to speak, built about 40 km from the great Aswan Dam, a marvel of modern engineering. Located in the heart of Egypt's southern desert, the ...

Sources and technology for hydrogen production: a review
A comprehensive review of various processes and possible sources of hydrogen production are discussed in this paper. The various process for hydrogen production reviewed includes industrial process i.e. steam reforming, thermal cracking, partial oxidation of fossil fuels, coal gasification, electrolysis, thermochemical etc. and new emerging processes like photolysis, photo-voltaic electrolysis, ...

Producing hydrogen using nuclear energy
The earliest means of separating hydrogen from water was by electrolysis using electrical energy that usually had been produced by low-efficiency thermodynamic processes. Substitution of thermal energy for electrical energy in high-temperature electrolysis gives a somewhat higher overall efficiency, but significantly complicates the process. Today, the vast majority of hydrogen is produced by ...

Producing Hydrogen via Electrolysis
Electrolysis has been gaining momentum in recent times as an option for carbon-free hydrogen production from both nuclear and renewable sources. Electrolysis uses electricity to separate water into hydrogen and oxygen inside a unit called an electrolyzer. This article will outline the process of electrolysis, how it works, and its ...

Exergy analysis and environmental impact assessment of a photovoltaic-hydrogen production system
In this study, exergy analysis and environmental impact assessment of a Photovoltaic (PV)-hydrogen production system and its components are carried out. Actual data measured in the system are employed for analysis purposes. Daily hydrogen production amount from solar energy through water electrolysis is 4.43 kg. The average system exergy efficiency is determined to be 3.18%. It is found that the ...

The importance of clean water, a foundation for green hydrogen energy production
As the global economy starts fully integrating other sources of energy in addition to fossil fuel, solar and wind, green hydrogen is starting to gain momentum. Global leaders across industry and governmental agencies are developing aspiring and potentially paradigm shifting ways to produce lower carbon energy fuels such as hydrogen. In the interim, other companies are evaluating how hydrogen ...
