Corvus Energy, Bergen, Norway, announced its Dolphin NxtGen Energy marine battery system has received type approval from Lloyd’s Register (LR). 

The type approval confirms that the energy storage system (ESS) complies with the industry rules, regulations, and safety requirements as defined by the London-based maritime classification society. 

The Corvus Dolphin NxtGen Energy design draws upon the Corvus Orca ESS, featuring safety measures such as passive single-cell thermal runaway (TR) isolation and a TR gas exhaust system.

With its lightweight construction, high energy density, and modular design, the Dolphin NxtGen ESS is optimized for both space and weight efficiency aboard vessels such as passenger ferries, tourist and sightseeing vessels, and canal boats, according to the manufacturer.

In addition to securing LR, Bureau Veritas and DNV type approval, Corvus Energy said it is pursuing type approval certification from additional maritime classification societies for the Dolphin NxtGen Energy product.

In 2023, Corvus Energy which operates manufacturing and engineering facilities in Porsgrunn and Bergen, Norway, as well as in Richmond, British Columbia — opened a manufacturing facility in Bellingham, Wash. to help meet growing demand in the U.S. market.
