The Energy Technologies Institute (ETI) and HR Wallingford launched a tidal energy modeling tool for use by tidal energy developers to identify the most efficient sites for tidal energy converters, tidal arrays or tidal barrage schemes around the U.K. and French coastlines. The computer program, SMARTtide (Simulated Marine Array Resource Testing), incorporates a 2D hydrodynamic model of the U.K.’s continental shelf and the north-west European coastline. The software will be available to the public from May 21 as a fee-for-service via a portal on HR Wallingford’s website.
