Caudal Energy Raises $5.6 Million to Generate Power from Marine Mammal-Inspired Tidal Tech

UK-based clean energy startup Caudal Energy announced that it has raised £4.3 million (USD$5.6 million) in a seed funding round to support the development of its technology to generate low-cost and reliable baseload power from tidal stream energy.
According to the company, while tidal energy has long been recognized for its predictability, commercial deployment has historically been constrained by the complexity and economics of turbine-based systems operating in a limited number of extreme conditions.
Founded in 2024 as a spinout from the University of Oxford, initially as “Porpoise Power,” Caudal Energy develops bio-inspired tidal energy systems that use oscillating fins modeled on the movement of marine mammal tails to generate predictable renewable electricity. The company’s solution replaces the turbine-based systems used by current tidal energy approaches with an oscillating fin system inspired by marine mammals.
According to the company, its platform is designed to address the limitations of current solutions by operating efficiently in mid-flow tidal environments with peak flows above three knots, significantly expanding the range of viable deployment locations for tidal energy systems.
The company said that the platform’s modular architecture simplifies installation and maintenance, reduces operational complexity and costs, and creates a more commercially scalable pathway for tidal energy deployment across utility-scale, industrial, and distributed energy applications. The company added that its technology is designed to provide predictable baseload renewable power at costs competitive with established clean energy technologies such as offshore wind.
John Kennedy, CEO of Caudal Energy said:
“Our approach combines smarter hydrodynamic design with modular deployment architecture to create a system designed for real-world performance. By unlocking the potential of mid-flow tidal sites, we believe Caudal can dramatically expand where tidal energy can be deployed and how commercially competitive it can become.”
The company said that the new capital will support the expansion of its engineering and modelling capabilities, demonstration and deployment activities, and commercial partnerships, while advancing its fin-based tidal technology, with the first commercial deployment targeted for 2028.
The new funding round was co-led by Oxford Science Enterprises and Empirical Ventures, with participation from existing investors Zero Carbon Capital and Creator Fund, alongside new investors Kibo Invest and Oxford Innovation Finance.
Andy Straiton, Investment Lead at Oxford Science Enterprises said:
“Caudal Energy is addressing one of the most important challenges in the transition to renewable energy: how to provide predictable, scalable generation that complements intermittent power sources such as wind and solar. Importantly, Caudal’s approach is designed around the economics required for large-scale deployment, not just technical performance. The combination of simpler deployment, lower operational complexity and access to a far broader range of viable sites can make tidal energy cost competitive with established renewables such as solar and wind.”
