Test of metal

"There's a whole group of vessels that haven't pursued full electrification because they couldn't achieve their objectives on battery power alone," says Ben Gully, chief technology officer at LAVLE, producer of the Proteus energy storage system that utilises batteries produced by parent company 3DOM. Similarly, he adds, there's another set "that has even fallen outside the case for hybridisation". However, much of this is about to change. While they're arguably the most flexible of green technologies and the 'marriage broker' between alternative energy sources, batteries have limitations. Of these, "the really big one is energy density", says Gully. He explains: "As we continue to push traditional Li-ion batteries to higher and higher energy densities, the industry has been forced to make substantial sacrifices on both safety and cycle life."
