Congratualtions to Mojo Maritime and Tidal Energy Ltd for completing a complex operation in the challenging conditions that the prevailing weather at this time of year has thrown at us.
Called DeltaStream, the device will, according to the company, become one of the first grid-connected demonstration devices worldwide to generate green, sustainable and predictable tidal power. The device was loaded off the quayside in Pembroke Port by the
Managing Director of Tidal Energy Ltd, Martin Murphy, said: “The deployment of DeltaStream marks a significant achievement for the original inventor of the device, Richard Ayre, and for our team, our shareholders, Wales and the wider tidal industry. We are immensely proud to be one of the frontrunners of tidal energy development in this nascent industry, which has great and far-reaching potential for green energy production.”
Weighing 200 tonnes, with a frame 16m long and height of 18m, the DeltaStream 400kW demonstration device has a gravity-based foundation which sits on the seabed under its own weight, without the need to drill or pile the structure into the seabed. The end goal is to place three, 400kW turbines on the foundation to produce a total of 1.2MW per unit. To read more about the device click HERE.
Eco2 Ltd, CEO, David Williams said that the company looks forward to demonstrating the viability of this technology and developing its commercial scale demonstration project at St Davids Head.
This site at St Davids Head in Pembrokeshire is two miles north of Ramsey Sound and is being developed by Eco2 in partnership with Tidal Energy Ltd. This should involve up to nine DeltaStream devices being deployed, generating enough power for approximately 10,000 homes.
The company says that Ramsey Sound was chosen as the test-site for the device because it is sheltered from prevailing wind and wave conditions, but has a good tidal climate with tidal streams reaching up to 3m/s on spring tides. There is a good grid connection feeding electricity to St Davids city and excellent port facilities and marine engineering capabilities nearby in Pembroke Port.
Chris Williams added, “We have worked closely with the local supply chain and contractors to install the necessary infrastructure to make this project happen. We would like to thank those organisations involved for their hard work, resilience and support which has helped us reach this pivotal milestone. We look forward to building upon this by further developing skills and creating green jobs in the area.”
