Quaise Energy Expands Series A to $52M to Unlock Terawatt-Scale Geothermal Energy

Expanded Series A funding enables new strategic partnerships

CAMBRIDGE, Mass.--()--Quaise Energy, Inc. (“Quaise Energy” or the “Company”), the company unlocking terawatt-scale geothermal, announced today that it expanded its Series A financing round from $40M to $52M. The $12M incremental round was led by TechEnergy Ventures, the Corporate Venture Capital group within the Energy Transition Division of Tecpetrol, which is a part of the Techint Group. HostPlus, Prelude Ventures, Safar Partners and Xplorer Capital also participated in this financing.

“Our new sponsors are sophisticated investors that recognize Quaise Energy’s potential to accelerate the clean-energy transition and open access to renewable baseload power from anywhere on Earth,” said Quaise Energy Co-Founder and Chief Executive Officer Carlos Araque. ”We will use the additional investment to expand our technology development roadmap and form foundational strategic partnerships that further scale our business.”

Geothermal is the only renewable, clean source of energy capable of providing baseload power at the scale required for a global energy transition. Quaise Energy plans to unlock deep geothermal by developing and using millimeter wave drilling systems capable of reaching depths between 10-20 km. At these depths, geothermal energy is power-dense, virtually unlimited, and available everywhere on the planet.

“We believe that UltraDeep Geothermal has the potential to dramatically improve the probability of reaching challenging net zero targets,” said Alejandro Solé, Chief Investment Officer at TechEnergy Ventures. “The success of Quaise Energy’s millimeter wave technology in overcoming traditional obstacles to superhot, super-deep drilling will enable clean, continuous and affordable energy everywhere.”

Carlos Araque added, “There is no energy transition without deep geothermal. Deep geothermal offers an always-on, inexhaustible energy source without fuels, without waste and without geographical limitations. It is also the most powerful, reliable and abundant primary clean-energy source on Earth.”

Quaise Energy will build field-deployable machines to demonstrate the capabilities of its novel drilling technology under real geological and operational conditions and then go on to repower traditional fossil-fired power plants with clean geothermal steam by the end of the decade.

Quaise Energy spun out of the MIT Plasma Science and Fusion Center in 2018. The Company has raised $75M to date.

Quaise Energy is terawatt-scale geothermal. We’re opening access to renewable, baseload power from anywhere on planet Earth. Deep geothermal uses less than 1% of the land and materials of other renewables, making it the only option for a sustainable clean energy transition.

Our approach to deep geothermal is unique in being geography agnostic: by outfitting existing drilling rigs with millimeter wave technology, we’re opening the way for power-dense, deep geothermal energy on a global scale. The path to terawatt-scale clean energy doesn’t require building global infrastructure. Quaise Energy is accelerating the clean-energy transition by repowering the fossil-fired infrastructure of today’s energy industry with clean geothermal steam.
