30 MW at Morlais

HydroWing Ltd have been awarded a berth with 30 MW potential at Morlais a tidal site located in Angelsey, Wales, and operated by Menter Môn. The company plans a phased approach starting with a commercial demonstrator project in 2023 which will be operated by HydroWing’s newly established Welsh entity: HydroWing Tidal Projects Ltd. The initial project looks to cement the technology at the site, grow the Welsh team and develop the essential strong local supply chains and stakeholder relations to subsequently enable roll out toward the full 30 MW.
The device will be installed using the recently acquired Inyanga Entsha the new Dynamically-Positioned (DP2) Multi-Purpose Vessel. The Entsha, powered by DC Electric Propulsion, offers 35% increased energy efficiency leading to very low fuel consumption and high reliability unlocking efficient processes for the HydroWing’s installation, Operation and Maintenance. The vessel is currently in Appledore, Devon, where it is being upgraded with intelligent launch and recovery systems. Inyanga Entsha in combination with Tocardo’s reliable turbines and a low-cost mobilisation strategy are key to ensuring that tidal energy can compete with other renewable energy technologies.

HydroWing will work closely with the local supply chain in North Wales to deliver this demonstration phase. This commitment is strengthened with the joining of Marine Energy Wales cluster in early 2022. The front-end engineering design is currently being undertaken and over the next months HydroWing will undertake detailed analysis and design to ensure optimised configuration of the turbines.

Tocardo Tidal Turbines

The HydroWing device has been inspired by the Tocardo’s flagship OTP Project and the world’s largest single installation of tidal turbines (5 turbines). This 1.25 MW project has operated on the Eastern Scheldt barrier since 2015 with turbines arranged on a wing in a similar configuration to the HydroWing. The proven long term robustness, reliability and remote-control capability gives confidence to developing arrays of turbines on HydroWing. The key advantages of these turbines, aside from the proven reliability, is the compact nature of the device, allowing low-cost logistics using standard containers.

This project will demonstrate the next generation Tocardo T-2si Turbines configured into the HydroWing Structure. The new turbines will feature enhanced blade performance and control innovation to provide low cost, clean, predictable and reliable electricity to the Local Grid. The new turbines integrated with HydroWing configuration will reduce the CAPEX while retaining the excellent robust reliability for which Tocardo are renowned.

The five installed turbines on the Eastern Scheldt barrier have each accumulated 6 years of operation with 95% availability proving it to be a robust, reliable, and low-cost system with limited need for physical intervention- giving confidence to integrating these turbines into HydroWing’s subsea system to take advantage of tidal sector’s biggest market segment.

HydroWing Technology

The HydroWing is a multi-rotor subsea device with three turbines mounted on a wing like structure which is stabbed onto a sub-structure, a modular gravity-based frame mounted on the seabed.

The device can be a single or double wing, depending on the depth of water at the site. The key advantages of the technology are the enhanced redundancy of the multi-rotor system and the high packing density capable of extracting 275 MW/km² of seabed space with robust simplicity and reduced CAPEX. The Power is integrated through the patented Turbine Control Hub mounted in the wing and electrical/ data connection is via wet mate connectors, allowing quick and simple installation and recovery.

Quotes

Richard Parkinson, MD HydroWing: “We are very excited to demonstrate our HydroWing with the next generation Turbines at Morlais. Our key objective is to demonstrate that tidal energy can be cost competitive versus other renewable energy sources. We look forward to working with the local supply chain and collaborating with other developers at Morlais.”

Andries van Unen, CEO Tocardo: “For Tocardo, the development of the T-2si turbine marks an important milestone on the technology roadmap and will open the door to the offshore tidal market. With the HydroWing, our expertise, business partners and existing technology base, the Morlais project is the perfect stepping stone for Tocardo to determine our course and to claim our position in the market.”

Gerallt Llewelyn Jones, SRO Morlais Energy: “Morlais welcomes Inyanga and we look forward to a productive relationship in progressing this important industry and creating benefits for the local and regional economy.”
