ESS Tech Appoints Harry Quarls as Chairman of Board of Directors

With over 40 years of energy experience, Quarls brings considerable strategic, financial, transactional, and energy investing experience to ESS as the company continues to scale to meet global demand for LDES. Over his long and storied career, Quarls served as a Managing Director at Global Infrastructure Partners, leading their efforts in North American energy midstream investments, and as Managing Director and practice leader for Global Energy as well as a member of the board of directors at Booz & Company.

“We are thrilled to bring someone of Harry’s stature to the board of ESS,” said Niggli. “The company is making strong progress and delivering the energy storage products that customers need. Adding Harry to the team will prove invaluable as we continue to expand our capacity and scale to achieve the full market potential of our patented, safe and cost-effective long duration storage solutions.”

“Harry’s long career advising and leading successful, growing companies spans many pivotal transformations in the energy sector,” said Eric Dresselhuys, CEO of ESS. “Today, the industry is once again at a pivotal moment, and long-duration energy storage represents one of the most important growth opportunities in the global transition to clean energy. I look forward to Harry’s strategic thinking, global partnering and experience growing successful energy and infrastructure businesses as ESS scales to meet global demand.”

“The transition to new, cleaner forms of energy is already underway. As it accelerates in coming years, it is clear that the switch to renewable energy sources will require large volumes of long-duration energy storage to deliver the reliable, clean energy the world demands,” said Quarls. “ESS is perfectly positioned to meet this demand with proprietary technology that is readily scalable and which leverages flexible, accessible supply chains. I am excited to join ESS during this period of growth to drive world-class shareholder value.”

Quarls currently serves as chairman of the board for CHC Helicopter, Key Energy Services, and Mesquite Energy. He is also a Director at Seadrill and has served on the boards of a number of private and public companies. He holds BS/ScM degrees in Chemical Engineering from Tulane University and MIT, respectively, and an M.B.A. from the Stanford Graduate School of Business.
