Latest Climate tech Startup Funding Rounds

A producer of adsorption materials and heat-pump systems that use low-temperature waste heat to generate cooling.

A geothermal technology company developing closed-loop power generation alongside drilling and well-maintenance services.

Aukera Energy develops, finances, constructs, and operates utility-scale renewable-energy and battery-storage projects.

A carbon-capture technology developer using amine-containing gels and membranes to separate carbon dioxide from industrial gases.

VVater develops water-treatment and reuse systems built around its Farady Reactor.

Octave.energy supplies battery energy storage systems paired with its proprietary energy-management software to businesses from SMEs to industrial operators. The batteries store power on site while the EMS coordinates solar self-consumption, peak reduction, EV charging and market flexibility, helping customers manage costs and constrained grid connections.

Serwas installs and operates water-cooled GPU servers at heat-demanding sites, using their computing output for AI workloads and their recovered heat for buildings such as swimming pools and hotels.

Rightcharge gives electric-vehicle fleet managers one system for public and home charging payments, driver access and charging data. Drivers use a card and app for public networks and connect their home charger and energy tariff so reimbursements can be calculated accurately and paid to their energy supplier; managers receive consolidated billing and fleet analytics.

Newlight develops a hydrogen-hybrid retrofit for commercial ships that injects hydrogen into existing diesel engines to improve combustion, reducing fuel use and emissions without replacing the engine.

Develops biomass electrolysis to produce hydrogen and biogenic carbon dioxide from agricultural, forestry and industrial residues.
