Our 2025 cleantech cohort

Meet the innovators that were selected for our latest venture accelerator programme.

These companies were selected for their incredible potential to turn their ideas into solutions for key environmental challenges. Through our tailored programme of venture mentoring, masterclasses, investment support, and more, we will work with them to accelerate their technologies and realise their impact for a cleaner, more sustainable planet.

R3V Tech

Plug-in Cleantech to convert waste into green solvent

We have developed a novel reaction pathway that enables undesired crude glycerol from biodiesel process to be converted into green solvent (Solketal) through electrochemical transformation at room temperature and pressure without cathalyst increasing 50 times its market value. This is novel and inventive and represents a unique capability.

Ail Arian

Recyclable silver conductive inks for sustainable printed electronics

Our silver conductive inks facilitate the recycling of electronic waste without any of the highly toxic chemicals currently used, while enabling the separation of the substrate and electrical components. The silver recovered by our process can be reused in the formulation of new conductive inks, reducing costs and environmental impact.

Sustainable Sailing

Through green chemistry and biotechnology, we render the unrecyclable, recyclable.

We are challenging how circular economy focussed technologies are built, to enable zero waste manufacturing for businesses. By developing green chemistry and biotechnology solutions, we render the unrecyclable, recyclable, reducing the flow of manufacturing waste to landfill for businesses, while providing high performance products.

Kodiaq Technologies

Metal-free electrolytes for battery-based long-duration energy storage

We have developed innovative, high-energy-density electrolytes for renewable energy storage. These electrolytes consist of metal-free molecules and, in conjunction with redox flow batteries, offer an alternative to current metal-based technologies. With their high energy densities, they provide significantly increased return on investment and strengthen the case for renewable energy installations.

Mantisonix

Sound waves to eliminate forever chemicals (high-frequency ultrasound)

Our technology destroys PFAS (per- and poly-fluorinated alkyl substances) and other persistent pollutants. We use sonolysis (ultrasound cavitation) to convert pollutants to naturally occurring compounds. The process is catalyst- and chemical-free and is robust for different contamination types. Our process is highly scalable and is suitable for in-situ deployment.

Solveteq

Maximising Metal Extraction

Metals are essential. However, extracting and refining metals is energy-intensive and expensive. Solveteq’s proprietary solvent-based technology platform extracts various metals at near room temperature, slashing energy use by up to 90% and CO emissions by up to 75% while maximising metal recovery.

Mode Labs

Plug and play remotely deployable chemical sensors for pollution monitoring

Using optical microcavities, we deliver plug-and-play chemical sensing capabilities in the field, with 10,000x increased sensitivity and 6x longer deployments, at 10% of the cost. Our patented platform technology can be expanded to any analyte in liquid, with applications in water, aquaculture, health, and security markets.

Repolywise

First truly closed-loop for waste polyolefin plastics

Repolywise transforms waste plastics to new via a catalytic technology inspired by research at the University of Oxford. We degrade polyolefins back into their monomers (chiefly propane) in a highly selective, one-step process, operating at lower temperatures and pressures than prior processes, with good catalyst longevity.
