Albatross Energetics ↗

Makes liquid-desiccant air-treatment systems for industrial dehumidification and clean rooms. A liquid absorbs moisture and is regenerated with heat, allowing humidity and temperature to be controlled together. Products include air-handling units and heat-and-mass-exchanger kits.

Helionis Labs ↗

Develops insulated metal substrates for power electronics and high-power lighting. These circuit-board foundations combine electrical insulation with heat transfer, removing heat from controllers, chargers, converters and LEDs. Its own site describes an in-house insulating material and additive manufacturing process.

GreenTech MW ↗

Provides wind-turbine operations, maintenance, spare parts and asset-management services. Its own site also describes cloud monitoring, AI and robotics for renewable assets. The core business is keeping wind installations running, not manufacturing an entire turbine.

Hydgen ↗

Builds modular on-site hydrogen-generation systems using water electrolysis, gas conditioning and controls. The systems supply high-purity hydrogen at the point of use for industries including diamonds, chemicals and semiconductor manufacturing, reducing dependence on transported gas.

Matel Motion ↗

Designs and manufactures electric motors, drives, controllers and geartrains for vehicles, industrial equipment and solar pumps. Its in-house powertrain work combines the motor with the electronics and transmission parts that control and deliver motion.

Dynolt ↗

Develops power converters for electric-vehicle chargers, battery-swapping stations, solar and battery-storage systems, and hydrogen equipment. Digital control algorithms and modular hardware regulate how electricity changes voltage and flows between sources and loads.

Promethean Energy ↗

Builds industrial waste-heat recovery systems and heat pumps. Products recover heat from compressors, chillers, exhaust gases and wastewater for hot water or process heating, with connected monitoring. This reuses heat a factory would otherwise discard.

CIMWare ↗

Develops a composable-infrastructure module for data centres. Its top-of-rack network switch and software make compute, storage and network resources available as shared services, aiming to reduce physical scaling and power use. It is data-centre hardware, not a semiconductor manufacturer.

Protonas ↗

Develops proton-exchange-membrane hydrogen fuel cells, which combine hydrogen and oxygen to make electricity and water. Its air-cooled architecture is being developed for backup power, delivery vehicles and drones. Product ranges and endurance statements include design targets, not confirmed commercial performance.

Emo Energy ↗

Integrates immersion-cooled batteries, charging hardware, energy storage and management software. Its NEXO system manages energy from the grid to vehicles, while thermal and battery-health controls manage heat and battery condition. It supplies an energy system rather than just a standalone cell.

EarthEn Energy ↗

Develops modular heat batteries for industrial steam and hot-air demand. Renewable electricity or waste heat charges a solid storage bed, which later releases heat into a factory process. Its current site leads with solid-media heat storage, not only its earlier carbon-dioxide power-cycle technology.

Additional manager-linked investment outside the 18-name portfolio grid; the co-founder also lists an investor and board role. Fund vehicle and ownership percentage were not disclosed.

SUIND ↗

Builds vision-first autonomy for flying robots. Cameras and onboard computing help its Bumblebee drone understand three-dimensional terrain and navigate around obstacles with less dependence on GPS. Agriculture is the first deployment, with inspection applications also described.

ZeroDrag ↗

Designs and sells drone electronics including flight controllers, electronic speed controllers, radio receivers and satellite-positioning modules. These are the control, power and navigation components inside aircraft, not a claim that it builds every complete drone.

Comminent ↗

Builds open-standards machine-to-machine communications and device-management technology for smart utilities, cities and industrial networks. Radio-frequency mesh links allow devices to relay data through neighbouring devices, supporting smart-meter and sensor deployments.

Intrinsic Foundries ↗

Builds biorefinery systems that turn industrial carbon streams into biomass and higher-value biochemicals. Its photobioreactors use biological cultivation to capture carbon dioxide, with downstream processes aimed at ingredients and materials. This is biotechnology for industrial carbon use.

Prithu ↗

Develops nature-based carbon-credit projects using regenerative agriculture and rice cultivation. Soil sampling, satellite data and field verification track changes on farms and support credit monitoring. It is a carbon-project and measurement business, not a carbon-capture machine maker.

WorkOnGrid ↗

Provides utility operations software combining smart-meter readings, industrial-control data and field workforce information. Its Grid platform supports data capture, analytics, work orders and automated responses, with AI tools for queries and reports. It is software, not metering hardware.

GreenFi ↗

Provides software for environmental, social and governance due diligence, risk assessment and sustainability reporting. It aggregates data and applies AI models to help banks and businesses assess customers, investments and supply chains. It does not itself generate clean energy.

Fitsol ↗

Combines carbon-measurement software with managed services for manufacturers. It helps measure emissions, plan reductions and arrange lower-carbon logistics, packaging, waste management and other services. The software-plus-services model is separate from physical clean-energy hardware.
