Tree Energy Solutions (TES) has appointed Clare Harris as Chief Executive Officer and Board Member. The decision comes as TES advances its portfolio of flagship projects, currently representing more than 1.5GW of electrolyser capacity, through final investment decision (FID).
The electrolyser projects will serve European, North American and Asian markets with resilient, flexible, low-carbon energy such as electric natural gas (e-NG).
Harris, having already held senior executive roles, offers global leadership experience in large energy portfolios, major infrastructure investment decisions and large-scale gas and energy asset development across Asia, North America, the Middle East and Europe. Regarding her appointment, Harris said: “The energy transition increasingly depends on the ability to build investable, scalable infrastructure that meets the growing need for energy whilst still accelerating decarbonisation. TES has built a uniquely positioned platform with high quality projects serving customers in every major market and exceptional partnerships. I am excited to join the Board, the team and our partners in the next phase of delivery and scaling to full potential.”
Marcel Alverà and Paul van Poecke, Co-Founders and Co-Chairmen, commented: “TES has built a unique platform at the intersection of energy security, infrastructure and decarbonisation. As our portfolio advances towards FID and execution, we are delighted to welcome Clare as CEO. Her experience in capital-intensive energy infrastructure and integrated value chains, major investment decisions and international partnerships make her exceptionally well positioned to lead TES through its next phase of growth and delivery.”
Marco Alverà, Co-Founder and Board Member, concluded: “From the beginning, TES has set out to solve one of the most important challenges in the energy transition: how to decarbonise existing energy systems at scale while strengthening energy security, and we are proving that it can be done. Today we have a strong portfolio of projects, world-class partners and a clear path towards delivery. Clare brings a rare combination of strategic vision, capital allocation and execution experience, and I look forward to working closely with her as TES enters this next chapter.”
