Well done to the USA (Wind and Water Power Technologies Office) for acknowledging that game-changing innovations are essential for speeding up the commercialisation of WEC technology, and that researching these innovations is most cost effective at early stages of technology development. A recent announcement proposed an innovation challenge, to be judged by numerical modelling and tank trials.
Market incentives for sea trials
For a long time, the value of a prototype marine energy technology, and hence the investment available for its development, has been measured on a 1D linear scale: technology readiness level (TRL). Consequently there has been market pressure to attain high TRLs at the lowest overall development cost.
