Caudal Energy, a company developing a new class of predictable renewable power systems, has raised £4.3 million in funding, led by Oxford Science Enterprises (OSE) and Empirical Ventures, with participation from other investors, including existing investors Zero Carbon Capital and Creator Fund.
The funding represents one of the most significant recent institutional venture investments into tidal energy in the UK, reflecting the important role predictable renewable power will play in balancing costs and system volatility.
Caudal Energy, founded as Porpoise Power in 2024 on breakthrough hydrodynamic research originating from co-founder Professor Adrian Thomas at the University of Oxford, is rethinking how tidal energy is generated from first principles.
Inspired by the efficiency of the tail or caudal fins of marine mammals, the company’s proprietary oscillating foil system works with tidal flows rather than against them, enabling a simpler, smarter and more commercially scalable approach to marine energy generation.
Its modular design simplifies installation, reduces maintenance costs and lowers operational complexity, creating a more commercially practical pathway for tidal energy to scale as part of future renewable infrastructure and complement intermittent renewable sources with dependable baseload generation.
