Carnegie Wave Energy Ltd.
RPS was commissioned to carry out a detailed site evaluation and conceptual design study examining grid connection feasibility, environmental sensitivities, wave resources and structural issues for the installation of innovative marine energy technology on the west coast of Ireland.
The Lower River Shannon holds a number of important environmental designations, including Special Area of Conservation (SAC), Special Protection Area (SPA) areas and hosts a number of rare and protected species, including internationally important numbers of birds such as dunlin, black tailed godwit and redshank, as well as other protected species such as bottlenose dolphins.
The CETO wave energy units self-tune to sea-state and wave patterns. The installation is anchored to the ocean floor, and uses seabed pumps which are driven by submerged buoys. The pumps pressurize the water to a high-level and it is transferred to shore by pipeline where it will drive hydroelectric turbines to generate power. The high-pressure water can also supply a reverse osmosis water-desalination plant –removing the requirement for the electrically driven pumps (which emit greenhouse gases) that would normally serve such plants. Following the very positive results of the study, the Irish Government will continue to work with Carnegie and key stakeholders to progress the implementation of the project to trial the technology in Atlantic waters.
