Tree Energy Solutions (TES)

TLDR

Tree Energy Solutions (TES) is a Brussels-based company converting green hydrogen and recycled CO2 into synthetic natural gas (e-NG), having raised EUR 235M including a EUR 140M Series C in April 2024.

Overview

Founded in Brussels in 2019, TES develops and commercializes electric natural gas (e-NG), a synthetic fuel produced by combining green hydrogen with captured CO2. The resulting gas is chemically identical to natural gas and can flow through existing infrastructure, enabling decarbonization of hard-to-electrify sectors without replacing pipelines or appliances.

The company's model focuses on production at scale in locations with abundant renewable energy (such as North Africa or the Middle East), then exporting e-NG to European markets via existing LNG terminals and gas networks. This approach avoids the need to build entirely new import infrastructure.

TES raised EUR 140M in a Series C round in April 2024, bringing total funding to EUR 235M. The round reflects continued institutional confidence in synthetic fuel pathways as a component of European energy transition strategy, particularly for industrial heat and shipping applications.
