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; ...

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 ...

Optimizing Water Treatment for Green Hydrogen Production
As the world intensifies its focus on green hydrogen production, a critical factor that often goes unnoticed is water treatment. The process of producing hydrogen through electrolysis involves complex chemical reactions and precise atomic calculations, making water treatment an essential part of the equation. In this article, we will discuss how understanding the atomic composition of water can ...

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 ...
