Daily Climate Tech & Sustainability Flash Summary

1) Climate tech startups are back in focus

•Trellis highlights 15 climate tech startups to watch in 2026, spanning data centers, materials, and climate adaptation.

•The strongest themes are:

- AI-enabled climate solutions: nearly 28% of climate equity dollars now go to AI-enabled plays.
- Data centers: pulled in almost $2 billion in funding as power and water needs surge.
- Materials / critical minerals: copper and lithium face projected 30–40% deficits by 2035, adding supply-chain and national-security urgency.
- Adaptation: funding is up 64%, signaling investor demand for resilience tools.

•Notable startups mentioned include:

- WAVR Technologies – generates water from atmosphere using waste heat from AI data centers.
- Aepnus Technology – converts industrial waste into useful chemicals.
- Beehive – AI platform for disaster preparation and response.

2) Pitch competition today

•Trellis is hosting the Data Centers pitch competition today at noon ET, with separate pitch events for materials and climate adaptation scheduled later in the series.

3) Clean energy and industrial decarbonization remain investment magnets

•New and visible climate startups continue to target:

- 24/7 industrial heat and power from renewables
- Large-scale battery storage
- Fossil-free fuels
- Zero-emission aviation

•Examples from startup coverage:

- Antora: its commercial unit is delivering 24/7 industrial heat and power from renewables in an operating setting.
- Form Energy: announced a 300 MW / 30 GWh deployment with Xcel Energy to support a Google data center in Minnesota; described as the largest battery energy storage system by energy capacity ever announced.
- Twelve: its AirPlant One facility is scheduled to begin production in 2026, aiming to produce E-Jet fuel at scale with interest from Alaska Airlines, IAG, Microsoft, and the U.S. Air Force.

4) ESG / climate capital is showing signs of recovery

•Climate-tech investment rebounded in 2025:

- Global venture and growth investment rose 8% to $40.5 billion
- 179 funds raised $92 billion in new capital, a record for climate fund closes

•The rebound is being driven less by broad ESG enthusiasm and more by profitability, resilience, supply security, and AI-linked demand.

5) Water and resilience are emerging as major 2026 themes

•Emerald Technology Ventures says water tech is entering a breakout phase:

- Water stress is increasingly being treated as operational risk, not just an ESG issue.
- Investors are expected to back smart leak detection and low-energy desalination.

•The report also points to fusion moving from long-range promise toward strategic positioning in 2026.
