We're building a great British wave energy company

The waters around the UK contain an abundant, inexhaustible source of power:  wave energy

We're developing patent-pending technology to strengthen UK energy security ...

... and to offer clean, reliable energy in demanding marine environments

About Ithera Energy

Our name comes from "Yyth", the Old English word for wave. 

Wave energy complements wind and solar by drawing on the ocean’s enduring movement, helping create a more balanced, resilient and secure national energy system.

Building on recent advances in the sector, we’re developing modular wave energy converter technology for marine environments where conventional power is expensive, carbon-intensive or difficult to deliver.

We're commercially-led and intensely practical, focusing on applications where reliable wave power can help improve resilience and reduce costs for offshore operations.

Together, our founders bring decades of experience solving hard practical problems across engineering, operations, climate change and rapid commercial growth.
