The VATTS project investigated how tidal energy could be used to power communities in Northern Ireland. Led by Queen’s University Belfast and industry partners, the team tested a new type of tidal turbine—GKinetic’s vertical axis CEFA12—designed to work in strong tidal flows like those found in Strangford Lough.
Researchers studied the site’s energy potential using advanced computer models and underwater sensors. They also worked closely with environmental regulators to ensure the technology wouldn’t harm marine life. A special underwater camera system was developed to monitor seals and other animals near the turbine, and collision risk was found to be very low.
The turbine was tested both while being towed and anchored in place. It successfully generated electricity, and data showed it could provide a steady source of power. The team then looked at how this technology could be used at Queen’s Marine Laboratory in Portaferry, a building with high energy needs. They found that combining tidal power with solar panels and battery storage could significantly reduce energy bills and carbon emissions.
While tidal energy doesn’t offer the quick financial returns of solar, it provides reliable base-load power, which is especially valuable for buildings with constant energy demand. The project also highlighted how local infrastructure and natural resources can be used to support clean energy solutions.
VATTS has laid the groundwork for future tidal energy projects in Northern Ireland and beyond, showing that small-scale, community-focused systems can be both practical and sustainable.
