November 20, 2025 – Climate technology is now the most sought-after investment category in global venture capital. In the first ten months of 2025 alone, climate tech startups secured an unprecedented $85.3 billion, breaking the previous full-year record of $78.2 billion set in 2021. With the U.S. Inflation Reduction Act (IRA) still reshaping market economics, falling clean-tech costs, and accelerating corporate net-zero commitments, capital is flowing at historic levels into next-generation batteries, carbon removal, electrolysis, sustainable fuels, and grid modernization.
Climate tech has surged to capture 28% of all global venture funding in 2025, surpassing the share AI held just two years earlier. Mega-rounds above $500 million have become common, particularly in sectors such as green hydrogen, long-duration storage, battery recycling, and direct air capture. Corporate venture arms including Google Ventures, Breakthrough Energy Ventures, Shell Ventures, and Airbus Ventures now anchor many of the largest deals, signaling intense strategic interest.
Landmark Funding Rounds Reshaping Climate Tech in 2025
This year has produced some of the most significant private financing rounds ever recorded in the clean-tech sector.
Northvolt raised approximately $5 billion through a blend of debt and equity, pushing its valuation to around $12 billion as it scales its next-generation lithium battery gigafactories across Europe and North America.
Hysata, the ultra-efficient electrolyzer pioneer, secured $2.8 billion, achieving an $11 billion valuation thanks to strong participation from Temasek, Bill Gates, and Fortescue.
In carbon removal, Climeworks extended its leadership with a $1.65 billion raise, pushing its valuation to nearly $5 billion as it expands industrial-scale direct air capture facilities.
Redwood Materials continued its dominance in battery recycling with a $1.4 billion round at an $8.2 billion valuation, supporting massive expansions in Nevada, South Carolina, and Europe.
Form Energy, creator of 100-hour iron-air batteries, locked in $1.2 billion, solidifying its position as a frontrunner in long-duration energy storage.
Advanced electrolyzer companies also boomed, with Electric Hydrogen raising $1.1 billion to accelerate high-efficiency systems for green hydrogen production.
Other major players — including Sila Nanotechnologies, Lilac Solutions, Brimstone, and TerraPower — also raised hundreds of millions to advance silicon-anode batteries, lithium extraction technologies, carbon-negative cement, and advanced nuclear reactors.
Across the top 50 climate tech deals of 2025, total capital deployed has already surpassed $42 billion.
Why Climate Tech Is Exploding Right Now
1. Massive Boost From the Inflation Reduction Act (IRA)
The IRA has transformed climate tech economics. Its uncapped tax credits — including 45X, 45Q, 48C, and 45V — allow companies to monetize incentives at close to full value. This reduces the cost of capital, increases project viability, and accelerates deployment of technologies ranging from hydrogen and clean fuels to direct air capture and grid-scale energy storage.
2. Clean-Tech Costs Are Falling Fast
Several breakthrough cost reductions are driving investor confidence:
- Green hydrogen production has dropped below $2 per kg in the best 2025 projects.
- Battery pack prices declined another 18% year-over-year.
- Direct air capture costs fell from around $600 per ton to under $250 per ton at leading companies.
These declines are making commercial-scale deployment increasingly practical.
3. Corporate Climate Commitments Are Accelerating
Large global corporations are locking in multi-year decarbonization commitments:
- Microsoft signed the world’s largest carbon removal contract, exceeding 10 million tons, with Climeworks.
- Amazon committed more than $2 billion toward low-carbon fuels and materials.
- Every major airline now maintains multi-billion-dollar agreements for sustainable aviation fuel (SAF).
Corporate offtake agreements are giving climate startups predictable revenue pipelines and bankable demand.
4. AI-Driven Energy Demand Is Transforming Investment Priorities
AI data centers are projected to consume 15–20% of all U.S. electricity by 2030, intensifying the need for clean, reliable, 24/7 power. This pressure is boosting investment in advanced nuclear, geothermal technologies, and long-duration storage — all essential for powering a high-compute future sustainably.
Fastest-Growing Sub-Sectors in 2025
Several segments of climate tech are experiencing explosive growth:
• Green Hydrogen & Derivatives surged with triple-digit growth thanks to both IRA incentives and global demand for ammonia, e-fuels, and industrial decarbonization.
• Advanced Batteries & Storage saw rapid funding increases as gigafactory expansions and iron-air storage solutions matured.
• Carbon Removal set new records, driven by DAC scale-ups and major offtake agreements.
• Sustainable Aviation Fuel (SAF) attracted billions as airlines commit to aggressive decarbonization timelines.
• Next-Generation Nuclear — including SMRs and early fusion ventures — experienced triple-digit growth fueled by energy security concerns.
• Climate Software + AI continued rising steadily, supporting emissions tracking, grid optimization, and industrial automation.
What’s Coming Next: The Trillion-Dollar Climate Tech Decade
Analysts expect cumulative climate tech investment to exceed $2 trillion by 2035, driven by several long-term catalysts:
- Extensions or global equivalents of the IRA, including the EU Green Deal Industrial Plan, Canada’s clean-tech tax credits, and Japan’s GX funding program.
- Continued declines in the cost of hydrogen, batteries, and carbon removal technologies, making them increasingly bankable.
- Regulatory pressure requiring corporations to procure real, verifiable decarbonization solutions.
For the first time, solving climate change is emerging not just as a necessity but as the largest economic opportunity in modern history.
