Tidal Alliance

Three leading tidal developers have joined forces as a Tidal Alliance at OEE2020, to show the world that tidal is ready for the main stage: Orbital Marine Power, SABELLA and Sustainable Marine Energy.

Europe leads the way in tidal energy globally, with European developers transforming the technology into a mainstream power source.

Orbital Marine Power

Scottish based Orbital Marine Power has established itself as the leader of innovative tidal stream engineering, having pioneered a unique floating turbine solution after over fifteen years of intensive research, development and scale model testing. Credited with developing the technology to transform the future of tidal energy on a global scale, Orbital’s proprietary technology is capable of producing a step-change reduction in the cost of energy from tidal currents.

Currently in construction is the Orbital O2 tidal turbine, which will be the world’s most powerful tidal turbine and is due to be installed at the European Marine Energy Centre’s Fall of Warness tidal test site in Orkney, in 2021. Click here for an in-depth visualisation of the O2.


Founded in 2008, SABELLA is a French pioneering tidal turbine developer. The technology is composed of a horizontal axis rotor installed on a gravity-based structure laying on the seabed.

Full-scale D10-1000 turbine was successfully installed in 2015 in the Fromveur Passage. The 1 MW tidal turbine was grid-connected to Ushant Island and supplies electricity to the 800 inhabitants of this off-grid area.

Since 2015, SABELLA has optimized and validated the electrical and mechanical performances of its 1-MW full-scale turbine, in harsh real-sea conditions. Now, the company is working on the design and construction of commercial pilot tidal arrays in France and overseas.

Sustainable Marine

Sustainable Marine supplies tidal energy generation platforms incorporating SCHOTTEL powertrain and control systems. Over the past three years we have focused on developing and proving PLAT-I system, testing the first demonstrator in Scotland, and since 2018 we have continued the testing in Nova Scotia, at Grand Passage, in preparation for our project at FORCE.

Jason Hayman the Managing Director of SME said “The FORCE site is renowned for its incredible tidal resource, but this also makes it a very challenging environment in which to deploy equipment. We would like to thank the Government of Nova Scotia for remaining steadfast in their support of tidal energy. This enables us to continue our staged approach to delivering our objective; reducing the cost of tidal energy.“
