en.Wedoany.com Reported - Japanese energy company Idemitsu Kosan has invested in Quaise Energy to accelerate the development of next-generation geothermal technology. The investment was made through its wholly owned subsidiary, Idemitsu Americas Holding Corporation (IAH).

Idemitsu Kosan has a long history in geothermal power generation in Japan, beginning in 1996 with a steam supply contract with Kyuden Mirai for the Takigami Power Station. In 2017, Idemitsu Kosan began independently operating the 5 MW Takigami binary geothermal power plant. Currently, the company is collaborating with INPEX and Mitsui Oil Exploration to build the 14.9 MW Katatsumuri Yama geothermal power plant in Akita Prefecture, which is expected to commence operations in 2027.

Quaise is developing a proprietary millimeter-wave drilling technology that is expected to be applied in next-generation geothermal systems. The company recently announced that it will soon begin drilling for a 50 MW geothermal power project in Oregon, aiming to utilize its innovative technology to access ultra-high-temperature geothermal resources. Through its partnership and investment in Quaise, Idemitsu Kosan stated that it will further consider participating in next-generation geothermal projects.

Keitaro Sugihara, President and CEO of Idemitsu Americas Holding Corporation, stated that combining Idemitsu Kosan's resource development expertise with Quaise's millimeter-wave technology will strengthen global energy security, and the investment in Quaise will accelerate the development of next-generation geothermal technology, marking an important step toward achieving stable energy supply. Carlos Araque, CEO and President of Quaise, added that they welcome Idemitsu Kosan as a strategic investor to jointly develop more powerful and economical geothermal energy globally using millimeter-wave technology, noting that Idemitsu Kosan has decades of experience in resource development and geothermal operations, and both parties share the goal of providing reliable, affordable, and sustainable energy worldwide.
