Geothermal Energy Use in Hydrogen Production
(Yildiz Technical University, 2016-04)
We propose the use of geothermal energy for hydrogen production and liquefaction, and investigate six possible models for accomplishing such a task. The models are studied thermodynamically in order to assess their performance ...
Performance assessment of an integrated PV/T and triple effect cooling system for hydrogen and cooling production
(2011-08)
In this paper we study an integrated PV/T absorption system for cooling and hydrogen production based on U.A.E weather data. Effect of average solar radiation for different months, operating time of the electrolyzer, air ...
Economics of hydrogen production and liquefaction by geothermal energy
(2012-01)
Seven models are considered for the production and liquefaction of hydrogen by geothermal energy. In these models, we use electrolysis and high-temperature steam electrolysis processes for hydrogen production, a binary ...
Coupling of copper-chloride hybrid thermochemical water splitting cycle with a desalination plant for hydrogen production from nuclear energy

Exergy analysis of heat exchangers in the copper–chlorine thermochemical cycle to enhance thermal effectiveness and cycle efficiency
(Oxford University Press, 2011)
Most existing nuclear power plants in North America are typically water-cooled and operate at 250–500°C. For this temperature level, the copper–chlorine (Cu–Cl) cycle is one of the most promising cycles that can be integrated ...
Process simulation and analysis of a five-step copper–chlorine thermochemical water decomposition cycle for sustainable hydrogen production
(Wiley, 2014)
A process model of a five-step copper–chlorine (Cu–Cl) cycle is developed and simulated with the Aspen Plus simulation code. Energy and mass balances, stream flows and properties, heat exchanger duties, and shaft work are ...
