What happened
Mazama Energy raised $135M in an oversubscribed Series B to develop horizontal wells in super-hot-rock geothermal, targeting depths of ~15,000 feet where 750°F heat creates supercritical fluid yielding up to 10x more power per well than traditional geothermal. The company's Oregon site is now estimated at 10 GW potential (up from 5 GW last year), with plans to generate electricity next year and reach 200 MW by 2030.
Why it matters
Enhanced geothermal is emerging as a contender for powering AI data centers, which matters if you're sizing infrastructure or evaluating where compute capacity will expand. For Malaysian builders, this is background signal: geothermal won't directly affect local power mix, but data center power constraints are a global bottleneck for AI services, and alternative energy sources like this could shift where new capacity gets built.
Discussion angle
Whether geothermal's 10x-per-well improvement and 63 TW global potential makes it a credible near-term answer to AI data center power demand, or just another deep-tech bet that won't ship at scale before 2030.
