Cleantech Startup Funding Reaches $15 Billion Amid Increased Energy Demand
Key points
- Investors infused $15 billion into cleantech in H1 2026
- Funding highest quarterly total since 2024 was $8 billion
- Largest round secured by Stegra with $1.6 billion for green steel
Current State of Cleantech Funding
Cleantech startups have seen $15 billion in funding during the first half of 2026, indicating a stabilization in investment despite a decline from previous highs in 2021 and 2022.
With electricity demand soaring and electric vehicle (EV) adoption increasing, funding for cleantech appears on track to surpass the total funding of 2025, which was noted for its low investment levels.
Quarterly Growth Trends
The second quarter of 2026 marked the highest funding level since 2024, with approximately $8 billion going to cleantech and related categories.
Despite this progress, cleantech now constitutes a smaller fraction of total venture capital compared to the ongoing AI boom.
Major Funding Rounds
Significant investments continue within the sector, with three of the largest recent rounds focused on fusion energy and electric vehicles.
Stegra, a Swedish green steel producer, secured the largest funding of 2026 with $1.6 billion to advance its steel plant construction.
Emerging Players in Cleantech
Slate Auto, supported by Jeff Bezos, raised $650 million to develop a versatile electric pickup truck, with plans for market release later this year.
Additionally, fusion startup Helion Energy raised $465 million for a new power plant, while Inertia secured $450 million to develop advanced laser technology aimed at power generation.
