# Quaise Energy

> Quaise Energy is an MIT spinout commercializing millimeter wave drilling, a technique that uses powerful gyrotrons to vaporize rock and bore holes up to 20 km deep - far deeper than conventional bits can reach. The goal is to tap superhot geothermal heat (up to ~500 C) almost anywhere on Earth, turning geothermal into a scalable, carbon-free baseload power source that can be delivered through existing power plant infrastructure.

- **Founded:** 2018
- **Headquarters:** Cambridge, Massachusetts, United States
- **Founders:** Carlos Araque (Co-founder, President & CEO), Matt Houde (Co-founder, Chief of Staff), Paul Woskov (Scientific Co-founder (MIT Plasma Science and Fusion Center)), Aaron Mandell (Co-founder)
- **Team size:** ~70 employees
- **Products:** Millimeter Wave Drilling, Superhot / Deep Geothermal Wells, Fossil Plant Repurposing
- **Notable:** Spun out of the MIT Plasma Science and Fusion Center in 2018 to commercialize Paul Woskov's millimeter wave drilling research., Raised over $90M in total funding to develop the technology., Demonstrated millimeter wave rock vaporization in the field, drilling a 118-meter borehole in 2025.

## Products & services

- **Millimeter Wave Drilling** — A drilling system that uses a high-power gyrotron to direct millimeter wave (microwave) energy down a borehole, vaporizing rock without any downhole hardware. This enables drilling through hard, hot rock like granite and basalt at depths up to ~20 km, far beyond conventional mechanical drilling.
- **Superhot / Deep Geothermal Wells** — Ultra-deep boreholes that reach temperatures up to ~500 C, accessing supercritical geothermal resources capable of producing renewable baseload power nearly anywhere on the planet.
- **Fossil Plant Repurposing** — Converting existing fossil fuel power plants to run on geothermal heat, reusing turbines, grid connections, infrastructure, and skilled workforce to deploy clean power quickly.

## Achievements

- Spun out of the MIT Plasma Science and Fusion Center in 2018 to commercialize Paul Woskov's millimeter wave drilling research.
- Raised over $90M in total funding to develop the technology.
- Demonstrated millimeter wave rock vaporization in the field, drilling a 118-meter borehole in 2025.
- Achieved drilling rates of up to five meters per hour through some of the hardest rock on Earth.
- Targeting a pilot geothermal power plant in the Western U.S. as early as 2028.

## Latest updates

- **2025-08** — Announced live demonstrations of its superhot geothermal drilling technology.
- **2025-07** — Achieved a drilling milestone, boring a 118-meter hole using millimeter wave technology in the field.
- **2024-03** — Closed a $21M Series A1 round led by Prelude Ventures and Safar Partners, with Mitsubishi Corporation and Standard Investments joining.
