Hydrogen production from water by thermochemical cycles

The enthaply of formation of potassium chromate(V), K3CrO4(c)

“…For example, such processes can be utilized in obtaining maximum useful energy from nuclear reactors (1). There is also potential value in using therrnochemical cycles that result in decomposition of water to yield hydrogen in fields where hydrogen may be needed as a chemical reactant, such as in bitumen processing and coal gasification.…”

Experiment and numerical analysis for sulfuric acid decomposition reaction for applying hydrogen by nuclear

“…A nuclear hydrogen system consists of a VHTR system, an intermediate heat exchange system, and a hydrogen production system [1,2].…”

Two-dimensional simulation of hydrogen iodide decomposition reaction using fluent code for hydrogen production using nuclear technology

“…In addition, in recent years, interest in and research on nuclear hydrogen technology, which involves direct decomposition of water to produce a large amount of hydrogen at high temperatures in a nuclear reactor as the heat source of the thermochemical cycle, has increased [30,31]. In particular, following the successful continuous operation of a bench-scale closed cycle gas turbine by the Japanese Atomic Energy Agency, SI thermochemical hydrogen production technology has taken center stage as one of the high-practical-potential hydrogen production technologies that could be coupled with the very high temperature reactor (VHTR) [32e36].…”
