Funding Friday: Public Markets > Private Investment

heatmap.news·May 22, 2026

Despite a slowdown in early-stage climate venture funding, several startups are securing investments and advancing innovative projects, such as REPS, which raised $23.6 million to convert kinetic energy from vehicles into electricity, and Deep Fission, which is planning a public offering for its underground nuclear reactor technology. Additionally, S2G Investments closed a $1 billion fund to support growth-stage climate tech companies, while Antora launched a significant thermal battery project in South Dakota to store excess wind energy.

The most valuable insight for you is the emergence of REPS, an Austrian startup that has raised $23.6 million to harness wasted kinetic energy from braking vehicles by embedding hydraulic plates in roads. This technology could potentially meet about 5% of global electricity demand if widely deployed, offering a novel approach to decentralized renewable energy generation. It's an actionable opportunity to explore partnerships or investments in energy harvesting technologies that capitalize on existing infrastructure, particularly in high-traffic areas like ports and industrial sites.
