Researching the Ultimate Fireless Steam Locomotive – Part II 

Chemical Thermal Energy Storage

Over the past decade, research was undertaken in Japan into high-temperature chemical thermal energy storage using metallic oxides. This research was aimed at storing thermal energy at thermal power stations during off-peak periods, then using that stored energy to generate extra electric power during peak demand hours. A team of research scientists based at the Tokyo Institute of Technology included Dr Yukitaka Kato, Dr Yamashita and Dr Yoshizawa who undertook research into the thermal reaction of magnesium oxide with steam. Another research team that included Dr Matsuda, Dr Kyaw, Dr Masanobu and Dr Hasatoru at Nagoya University based their investigation on the thermal reaction of calcium oxide and carbon dioxide. Information pertaining to this research can be accessed online at http://www.scej.org/ronbun/JCEJe/e29p0119.html . (LINK dead)

The injection of steam [H₂O] into a container containing powdered magnesium oxide [MgO] produced magnesium hydroxide [Mg(OH)₂] at a temperature of 300-degrees C to 350-degrees C (570-degrees F to 660-degrees F). The reaction released between 391-KJ/Kg and 556-KJ/kg or 168-BTU/lb to 239-BTU/lb of heat. The reverse reaction (decomposition) involved heating the magnesium hydroxide until it released the water vapour, leaving behind powdered magnesium oxide. Japanese researchers used a heat pump to transfer heat from a low-grade source and raise its temperature to enable magnesium hydroxide to decompose into the metallic oxide and water vapour…..
