Mazama Energy is a Frisco, Texas geothermal developer building Enhanced Geothermal Systems that tap superhot rock (SHR) - underground formations above 374 C - to deliver low-cost, round-the-clock, carbon-free electricity. Incubated by Khosla Ventures and backed by Gates Frontier, the company reached a world-record 629 F (331 C) bottomhole temperature at its Newberry Volcano pilot in Oregon and aims to produce power at under 5 cents per kWh, with 10x the power density, 75% less water, and 80% fewer wells than conventional geothermal.

Sriram Vasantharajan is the President and CEO of Mazama Energy, a Khosla Ventures and Gates Frontier-backed startup drilling into Oregon's Newberry Volcano to prove that superhot rock geothermal can deliver round-the-clock, carbon-free power at fossil-fuel prices. A former ExxonMobil engineer and CEO of oilfield services firm Blade Energy Partners, he is now applying decades of drilling and well-stimulation know-how from the oil patch to the geothermal industry, chasing rock hot enough to make a volcano's flank into a power plant.
