A competition to develop wave energy devices has seen 20 teams get through the first round.
They were selected by a panel of expert judges from 92 teams which were announced on the 6th of July.
The aim is to achieve the US Department of Energy’s (DOE) goal of doubling the power captured from ocean waves.
This is expected to reduce the cost of wave energy and make it more competitive.
The winners will receive a prize totalling more than $2 million (£1.3m).
Among other requirements, qualified teams will now build a 1/50th scale model and will participate in small-scale tank testing as a means of validating their concepts.
Finalist teams are scheduled to be announced in March 2016.
Wave Energy Scotland recently set up a similar competition.
