The Arab Energy Fund and Hartree Partners have launched a $120 million investment platform targeting decarbonization technologies in the U.S. and Europe, according to Gulf Business.
The initiative positions the Arab Energy Fund, formerly APICORP, as a global backer of sustainable energy solutions.
The UK-based fund, TAEF Hartree Cleantech LP, will invest in startups developing both physical and digital technologies aimed at reducing carbon emissions. The move is part of the Arab Energy Fund’s strategy to expand its impact investment portfolio in the energy sector, balancing energy security with sustainability goals.

Cleantech Focus
Hartree Partners has been active in clean energy investments since 2020 through its subsidiary, Vertree Partners, reports Golf Business. The firm’s portfolio spans industrial decarbonization, emissions tracking, geospatial data analytics, and climate adaptation technologies.
“The partnership reflects our strategy to support the energy ecosystem with debt and equity solutions and advances our member countries’ energy agenda by fostering local energy value chains in the MENA region and beyond,” said Khalid Ali Al-Ruwaigh, CEO of The Arab Energy Fund, as reported by Gulf Business.
Hartree Partners’ founding MD, Stephen Hendel, described the collaboration as a transformational opportunity.
He told Gulf Business: “We are proud to launch this platform alongside The Arab Energy Fund. Our combined expertise will allow us to identify and support transformational cleantech innovations on a global scale.”
Expanding a Global Network
The partnership builds on Hartree’s previous work with major investors, including BlackRock, Microsoft, and Union Square Ventures. With 10 active investments in the cleantech space, Hartree and the Arab Energy Fund plan to expand investment opportunities and accelerate the deployment of emissions-reducing technologies.
By pooling resources, the firms aim to support the growth of startups working on solutions for industrial pollution, carbon tracking, and climate resilience. The effort comes as global investors increasingly target clean energy projects amid tightening emissions regulations and the push for net-zero commitments.
