Energy from Limited Velocity Estuaries and Rivers

2026-07-22

An accelerated adoption of renewable energy generation is needed to meet the ambitious but necessary goals for low-carbon economy set by the European Commission (80% reduction from 1990 greenhouse emissions to 2050), and the G7 (elimination of fossil fuel generation to 2100). Despite good progress, it is still difficult to create a stable renewable energy generation mix, and to provide solutions that can reach all locations and communities in Europe, including remote communities. Significant parts of rivers worldwide remain an untapped energy resource, due to the lack of appropriate technology for hydro power extraction from remote/environmentally sensitive locations, or those with low-head, current velocity, or depth. Eel Energy, a French hydrotech startup, has developed a 1MW tidal energy converter based on biomimetic principles. Eel’s solution is an undulating membrane producing energy via linear converters, which significantly outperforms turbine-based technology in terms of simplicity, reliability, efficiency and environmental footprint. Eel Energy is now developing the ELVER (baby eel), a small (80kW), riverine-adapted version of their tidal generator. Compared with standard turbine solutions, ELVER will be able to reach higher efficiency and reliability, operate at lower heads and current velocities, and require far less civil works: reducing installation, operations costs, and environmental impact of installation. This technology has an unprecedented range of potential installation sites, and can play an important part in the sustainability of rural/remote communities. ELVER allows the development of new hydrokinetic resources, in both mature markets, and the developing world. In phase 1 of ELVER (6 months), we will characterise and quantify the riverine resources and the key advantages. Secure commercial trials locations, partners and funding for phase 2, and enhance our technical roadmap, roll-out strategy, commercialisation plan, and IP strategy.
