Current research

Under the aim of building a highly efficient energy system, comprehensive energy-circulation technology will be used to create a new energy cycle by adding "absorption" to "generation," "transmission," "store," and "utilization."

To create a new energy cycle, currently unused exhaust heat must be absorbed and converted into cold heat and electricity to circulate energy.

To achieve this aim for example, we are developing (i) technologies for transporting heat and generating cold heat by using as little energy as possible (by utilizing exhaust heat from data centers, etc.) and (ii) technologies for highly efficiently converting heat to electricity by utilizing higher temperature exhaust heat from factories and other sources.

It is said that unused thermal energy accounts for about 60-70% of primary energy in Japan ^[1], and it is generated in various places other than the above-described usage scenarios. By expanding the application areas of the technologies we have developed, we will contribute to the creation of a new energy cycle.
