About Hephae Energy Technology

Hephae Energy Technology, established in 2020, is a specialized developer of drilling technology designed to expand the viability of geothermal energy. The company was founded by Steve Krase (CEO) and John Clegg (President & CTO), who both transitioned from the oil and gas industry after recognizing the global potential of geothermal heat, particularly from hot dry rocks. Their shared background in developing downhole tools for harsh environments directly informs the company's approach. Hephae is focused on overcoming the temperature limitations of existing drilling equipment, which often cannot operate reliably above 200°C.

The company's core business revolves around engineering and manufacturing ultra-high temperature robotics, sensors, and integrated drilling systems for the geothermal industry. Its target clients are geothermal developers and drilling operators who need to access deeper, hotter rock formations to improve energy output and reduce the levelized cost of energy. By enabling access to these superhot rock resources, Hephae aims to make geothermal power a globally accessible, baseload energy source, independent of specific volcanic locations. Revenue is generated through the sale and deployment of its specialized drilling technologies.

Hephae's flagship product under development is the Pandora™ series, an integrated drilling system. The first iteration, Pandora210™, is a Measurement While Drilling (MWD) system rated to operate reliably at 210°C, with field trials scheduled for the second quarter of 2025. This system has been de-risked by demonstrating that its electronics can function for over 200 hours at temperatures exceeding its rating. The product suite is built on multiple pending patents for its electronics packaging and design, which includes a specially designed brushless DC motor and a board configuration optimized for heat flow. The company has a clear technology roadmap, planning to add Rotary Steerable System (RSS) technology in 2026 and release a 300°C-capable tool, the Pandora 300, by 2030.
