TSP Ventures Core Fund Grant

About this grant

TSP Ventures (The Sustainable Path) is a UK climate and deep-tech venture investor, launched in 2019, that backs early-stage hard science and breakthrough technology companies. Its stated mission is to back companies that deliver critical resources (clean air, freshwater, food, reliable energy, metals and minerals, steel and cement, plastics and chemicals, rare earths and other industrial inputs) in ways that are more cost-effective, more sustainable and more secure. The page describes a Pathfinder Fund, launched in June 2026 and reported as closed in October 2026, alongside a Core Fund. The page does not describe a grant programme. It is an equity investment offering, so there is no grant funding, application process, or awarded amount for applicants. TSP's investment verticals are future power and energy, future of food and water, critical materials, carbon mitigation, and adaptation, circularity and waste. The thesis rests on four macro forces: demographics, climate and environmental change, geo-security and supply-chain fragmentation, and AI-driven demand for energy and metals. TSP says it provides hands-on business, commercial and financial support alongside capital, and reports a track record of 25 investment rounds, 2 full exits, 1 partial exit, and over £10m deployed. The site also lists portfolio companies, including HiiROC (hydrogen production via plasma), DEScycle (e-waste metal recycling using deep eutectic solvents), Promethean Particles (metal organic frameworks), Taisan, and Nanomox. These are investees rather than grant recipients. The fund's own financial promotion disclaimers state that its investments are high-risk, illiquid, and may result in total loss of capital.

About this sector

Renewable energy funding covers solar, wind, hydropower, geothermal and bioenergy, from early research to grid-scale deployment. Public money tends to back demonstration, grid connection and access to energy in emerging markets, while procurement notices buy installation, operation and maintenance. Calls often ask for proof of resource assessment, permitting progress and local partners.
