"Designed to be moored at a single point, the PB3 PowerBuoy produces 300 W of continuous power (depending on ocean conditions) and 7.2 kW at peak (1 hour per day). As it floats over ocean depths of between 20 meters (m) and 1,000 m (Figure 4), it constantly recharges itself by harvesting energy from waves and then converting that wave energy to power through a direct-drive generator. That power then charges an energy storage system, which delivers power to meet application and end-user needs. Its modular battery has a capacity of 44 kWh and is scalable to 150 kWh."

The US Navy is interested in this technology for off grid power for navy bases.
It provides a benchmark for other wave energy companies wanting to get into the same market.
I am wondering whether the modest output is compensated for by having energy storage capacity?
