Basic Production

The way to decarbonization will be characterized by the huge production of hydrogen through sustainable routes. Thus, the basic production way is water electrolysis sustained by renewable energy sources allowing for obtaining “green hydrogen”. The present paper reviews the main available technologies for the water electrolysis finalized to the hydrogen production. We describe the fundamental of water electrolysis and the problems related to purification and/or desalinization of water before electrolysis. As a matter of fact, we describe the energy efficiency issues with particular attention to the potential application in the steel industry. The fundamental aspects related to the choice of high-temperature or low-temperature technologies are analyzed.

Test Reactor

The Japan Atomic Energy Agency (JAEA) initiated a high-temperature engineering test reactor (HTTR) demonstration program in accordance with recommendations of a task force established by the Ministry of Education, Culture, Sports, Science and Technology according to the Strategic Energy Plan as of April 2014. This paper explains the outline of the HTTR demonstration program with a plant concept of the heat application system directed at establishing a high-temperature gas-cooled reactor (HTGR) cogeneration system with 950°C reactor outlet temperature for production of power and hydrogen as recommended by the task force. A commercial deployment strategy including a development plan for the helium gas turbine is also presented.
