Idemitsu Kosan Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and CEO: Shunichi Kito) has invested in Thea Energy Inc. (Headquarters: USA; CEO: Brian Berzin) through Idemitsu CVC. Thea Energy is a startup working on the commercialization of fusion power using its proprietary stellarator device. Fusion is expected to be an innovative technology that supports sustainable energy supply. This investment aims to accumulate knowledge on technological trends and commercialization at an early stage.
Fusion is a technology that uses the enormous energy generated when light atomic nuclei fuse, similar to the reactions occurring inside the sun. It emits almost no CO2 and is considered safe as it does not cause chain reactions. In recent years, R&D has accelerated worldwide, and the Japanese government is also aiming for power generation demonstrations in the 2030s.
Thea Energy is a startup originating from the Princeton Plasma Physics Laboratory. While conventional stellarator devices have complex designs, the company significantly reduces equipment costs by using planar electromagnetic coils. It plans to build and operate a demonstration unit after 2027 and a commercial unit after 2030. Idemitsu will explore the possibility of using the electricity and heat generated from fusion for the production of synthetic fuels, ammonia, and hydrogen.
