Keynote presentation at 5th IMPRES 2019
At the 5th IMPRES 2019 (October 2019), we gave a keynote lecture entitled "Commercialization of Lithium Chloride-Modified Magnesium Hydroxide for Chemical Heat Storage".
Magnesium Hydroxide Based Heat Storage Material
Mg(OH)2-based Chemical Thermal Storage Medium that makes an exhaust heat utilization below 300℃ available
The CHARGEMAG® PM-1 Mg(OH)2-based Chemical Thermal Storage Medium has been developed through the collaborative research with the associate professor Junichi RYU of Chiba university. Though a normal magnesium hydroxide can only utilize waste heat above 350 °C, CHARGEMAG® PM-1 can make an exhaust heat utilization at the low temperature zone (about 300℃) available which could not be used before. The chemical heat pump using CHARGEMAG® PM-1 can be a system that effectively utilize waste heat at a low temperature which has not been effectively utilized so far. We will contribute to the realization of a low-carbon society by using this technology.
It can make an exhaust heat utilization at the low temperature zone (about 300℃) available which could not be used before.
It is an reversible chemical reaction.
It’s stable so it can be transported by vehicles.
By supplying water vapor at about 80℃, it can radiate heat.
• CHARGEMAG® store and radiate heat by using heat absorption / heat generation when magnesium hydroxide and magnesium oxide convert each other by chemical reaction.
• Magnesium oxide has an excellent stability under normal temperature and normal pressure, so CHARGEMAG® can store heat for a long time.
• This technology can effectively utilize factory waste heat throughout the country. Therefore, it can contribute to energy cost reduction at each factory.
• This technology can also utilize waste heat from cogeneration system, so it can offer energy saving services to energy operators etc. in addition to business owners who own factories.
Form: granulate
By combining metal salts, we succeeded in developing CHARGEMAG® PM-1, which starting temperature and peak temperature of thermal storage are about 50 °C lower than normal magnesium hydroxide.
Tateho is also developing products with lower storage temperature than CHARGEMAG® PM-1. Please inquire for detail.
