Climate Tech Startups

Eight global startups from the UK, Singapore, US, Japan, Estonia, and France were shortlisted for S$4M (~$3M USD) in funding at The Liveability Challenge 2026, focusing on decarbonisation and urban cooling; solutions include Endo Enterprises' additive reducing building cooling energy by 15%, FlueVault's low-cost carbon capture, Metha8's methanol-to-power, MacroCycle's textile recycling, Power To Hydrogen's hydrogen production, Spacecool's passive radiative cooling, UP Catalyst's flue gas-to-battery materials, and Yama's electrified carbon capture.[1]

Tech Nation selected 25 UK climate tech startups for its 2026 cohort, raising $250M+ collectively (avg. £9M/~$11.5M per company), employing 370+ people, with 76% planning global expansion; 23/25 focus on hardware/life sciences for food systems, industrial decarbonisation, energy, materials, and nature restoration, partnering with Microsoft, Shell, and others.[2]

Trending eco startups in April include Carbon Robotics (+1100% search growth) for ag robotics and Nautilus Data (+1200% growth) for water-cooled data centers reducing power use, emissions, and pollution.[3]

Greentown Labs highlights 2026 climatetech innovators like Alma Energy and Dandelion Energy in geothermal energy, and 247Solar and InfraNergy in solar-plus-storage for baseload renewables and virtual power plants.[4]

At SusHi Tech Tokyo 2026, watch startups like Synspective (weather-independent satellite monitoring for disasters), Kyoto Fusioneering (fusion energy), Challenergy (wind tech), TBM (materials), WOTA (water recycling), Sagri (AI soil analysis for climate-smart ag), and Planet Savers (scalable direct air capture).[5]

Other spotlights: Y Combinator's 49 climate startups (e.g., Releaf Earth on biochar carbon removal); Trellis' 2026 watchlist in data centers, materials, and adaptation; Korean climate tech at Scaleup Summit SF.[6][7][8]

Clean Energy & Environmental Innovations

Innovations emphasize deep tech: hydrogen production, methanol power, radiative cooling (mitigating urban heat), flue gas conversion to battery materials, geothermal scaling, modular solar with storage, fusion, and water recycling for disaster resilience; no specific new carbon impact metrics beyond energy savings (e.g., 15% cooling reduction).[1][4][5]

ESG Investing & Funding

UK cohort's $250M+ raised underscores investor shift to hardware/deep tech; global unicorns like Cruise ($2.1B), GAC Aion ($2.53B), GoodLeap ($800M), Northvolt ($150M) lead climatetech valuations.[2][9]
