Register for SOSV HAX Investor Showcase – April 1, 2026

One of the most promising solutions to the surging energy demand lies beneath our feet: geothermal energy. But drilling to the super hot rock many miles down is a vexing technical challenge and is one reason why geothermal provides less than 1% of global electricity.

Join us for a fireside chat with Carlos Araque (CEO, Quaise Energy), a spinout from the MIT Plasma Science & Fusion Center, that is pioneering a radically new drilling technology. An MIT-trained engineer, Carlos spent 15 years on complex energy systems at SLB (Schlumberger), before joining MIT’s The Engine to commercialize tech.

In this conversation, moderator Duncan Turner (General Partner, SOSV & Managing Director, HAX) and Carlos will explore: 

  • Why conventional geothermal stalled: the drilling physics & cost curves that historically confined geothermal to volcanic regions
  • Designing for superhot resources: what fusion-derived millimeter-wave technology reveals about reaching deeper, hotter rock
  • The realities of superhot rock: why higher temps dramatically increase power density & project economics
  • Partnering with Oil & Gas: lessons partnering with incumbents to accelerate geothermal deployment
  • Building the first superhot geothermal power plant in the U.S.: an inside look at Quaise’s Oregon pilot project & its upcoming commercial-grade flow test

If you’re building for the energy sector, this conversation is for you. Don’t miss it!
