400C Energy
400C Energy is developing all-metal multistage hydraulic fracturing technologies capable of operating at extreme geothermal conditions, exceeding 400°C and 15,000 psi. With TomKat support, the team will lab-test these technologies at superhot rock conditions to validate their mechanical performance and reliability. This testing represents a critical step toward enabling controlled reservoir stimulation and flow management in high-temperature enhanced geothermal systems (EGS). The validated technologies will be deployed in a pilot well on 400C Energy’s leased acreage in Utah, just four miles from the DOE-funded Utah FORGE site. This work builds on the founders’ doctoral research in EGS techno-economics and aims to accelerate the commercialization of EGS as a reliable source of 24/7 carbon-free power.
