Climate Tech Startups

Tech Nation announced its 2026 Climate Programme cohort of 25 UK-based high-potential climate and nature tech companies focusing on food systems, industrial decarbonisation, energy, materials, and nature restoration[1]. The group has raised over $250M collectively (average £9M per company), employs 370+ people, partners with corporates like Microsoft, Shell, and TotalEnergies, and 76% plan international expansion; 23/25 target hardware or life sciences for deep tech solutions[1].

Eight global startups shortlisted for S$4M funding at The Liveability Challenge 2026 (from 1,500+ submissions) address decarbonisation and urban heat in tropical cities, including UK's Endo Enterprises (15% cooling energy reduction in buildings), Singapore's FlueVault (low-cost carbon capture) and Metha8 (methanol-to-power), US's MacroCycle (textile recycling), Power To Hydrogen (hydrogen production), Japan's Spacecool (passive radiative cooling), Estonia's UP Catalyst (flue gas to battery carbon), and France's Yama (electrified carbon capture)[2].

Greentown Labs selected five startups for Go Build 2026 with Amazon and Global CO2 Initiative, developing CO2-mineralization tech for concrete aggregates to decarbonize construction[5].

Other highlights: Trellis seeks applicants by March 27 for 15 early-stage startups in data centers, materials, and climate adaptation[6]; Y Combinator funds 49 climate startups like OctaPulse (AI for fish farm QA)[7]; Enlit released Top 100 energy/climate tech startups list[9]; Scaleup Summit SF (April 2026) spotlights Korean climate tech[8].

Top valuations: Crusoe Energy Systems ($10B), Commonwealth Fusion Systems ($5.8B–$8.5B); ~55 unicorns, median $1.2B[3].

Clean Energy & Environmental Innovations

•Caban Systems (US): Modular energy storage for critical infrastructure; $2.9M raised[4].

•Greentown cohort targets carbon-valorization for built environment scaling[5].

•Liveability finalists advance clean energy (e.g., hydrogen, methanol power), carbon capture, recycling, and cooling tech with emissions/cost reductions[2].

ESG Investing & Funding Trends

Climate tech valuations show top 10 hold ~36% of total; median valuation-to-capital ~2x; examples include NotCo ($1.1B–$1.4B, $423M raised plant-based foods), HysetCo ($650M–$850M, $217M hydrogen), Charm Industrial ($600M–$850M, $125M bio-oil carbon removal)[3].

No new policy details in today's results; focus remains on startup acceleration programs bridging innovation to investors and customers[1][5].
