Ocean energy is making slow but steady progress. New Jersey-based Ocean Power Technologies (OPT) this week announced deployments of two of its ocean energy devices in two oceans, at sites off Hawaii and New Jersey, USA.

"With the New Jersey PowerBuoy successfully deployed and producing power, we are commencing discussions with certain utilities with a view to the next phase of scale-up to a megawatt-level power station." -- George W. Taylor, OPT CEO
