Renewable energy

Aed Energy's thermal battery enables renewable microgrids


Aed Energy couple novel thermal battery materials, coupled with smart photovoltaics to enable very low cost modular long duration electricity storage. Their target is to help the millions of current and future microgrids to move from diesel generators to intermittent renewable powre while keeping the lights on.

Twig makes ingredients using microbiology


Twig makes ingredients found in everyday products using microbial fermentation instead of intensive agriculture or petrochemicals. By replacing palm oil and other ingredients, 1.2 Gt CO2e could be saved per year by 2050. Twig uses bioengineering and AI to rapidly achieve high yields, enabling cost competitive bio-ingredients.

Industry & transportation


Ammonia production today is responsible for 2% of global GHG emissions, and this is forecast to grow as it is a leading contender to decarbonise the shipping industry. By synthesising ammonia directly from water and nitrogen, NitroFix’s electrochemical cells can make ammonia without carbon emissions at the lowest cost.

Carbon dioxide removal

RepAir suck carbon dioxide out of the air


Even as we decarbonise our economy we still need to reduce the amount of CO2 already in the air. RepAir's modular, electrochemical solution to direct air capture of CO2 promises to be both flexible and affordable.

Actuation Lab eliminate hydrogen losses


Switching parts of the economy to hydrogen has the potential to save 2.7 Gt CO2e/year by 2050. To do this we need to transport and store hydrogen without leaks, as H2 is a potent indirect greenhouse gas. Actuation Lab's redesigned valves eliminate fugitive stem leaks.

Lilac Solutions

Lilac has developed a new ion exchange technology for lithium extraction which cuts capital and operating costs, accelerates project startup, boosts lithium recovery, and unlocks new resources.



Microbyre can rapidly domesticate novel bacteria strains, genetically modifying them to perform useful tasks more efficiently like creating biodegradable plastic feedstocks from organic waste or making fertiliser from nitrogen in the air.



e-Zinc's zinc-based reactor technology system has the potential to provide long-duration, low-cost grid-scale energy storage. Electricity is turned into physically free zinc material.

Sepion - Blue_edited.jpg


Sepion develop a nanosieving membrane platform that drops in with existing manufacturing processes and exhibits broad utility in energy storage, water treatment, and chemical separations.



CleanFiber make cellulose insulation enabled by materials science breakthroughs, using recycled cardboard boxes as a feedstock. Better insulating properties and superior fire retardancy than regular cellulose or fibreglass insulation.



Rebound's tech supercharges industrial freezers. A proprietary freeze point suppression cycle designed around a natural refrigerant uses 35% less electricity than legacy, ammonia-based systems and 55% less than thermal or chemical batteries.



Gradient make a room air conditioner and heat pump that is twice as efficient and more accessible, that uses refrigerants with massively lower global warming potential.
