Waste heat becomes electricity onboard US Navy ship

Viking Heat Engines is turning waste heat into electricity onboard a US Navy ship currently on its way to Bridgetown in Barbados. The installation has been made possible through a close collaboration with Collins Aerospace, one of the world’s largest suppliers of aerospace and defense products in the US.

“It’s been a long road, but we’ve taken a great step, and the navy is really taking notice,” says Mike Mastergeorge, VP/GM, Thermal Process Management at Collins Aerospace. “The CraftEngine has been underway for one week, and the initial report is that it has been running very well.”

Less fuel needed

US Navy ships produce a lot of heat that is currently going to waste. By installing Viking’s CraftEngine, the Navy can tap into this underutilized energy source found on board its ships and transform it into electricity, heating and cooling to improve the energy efficiency and capacity of its fleet.

“By using waste heat to service multiple ship needs, the US Navy not only stands to save a lot in fuel costs,“ Mastergeorge says. “It also means ships don’t have to stop to re-fuel as often as they do today, which not only reduces the fuel consumption and environmental footprint but also the associated logistics trail, which is a critical capability for any Navy.”

A perfect match

Tor Hodne, Managing Director at Viking Heat Engines, says the CraftEngine is uniquely suited for marine applications.

“The CraftEngine can turn exhaust gas, jacket water and scavenge air, or a combination of all three, into electricity,” he says. “In other words, it can make large contributions in reducing fuel consumption and thus CO2 emissions, and save ship operators money.

“We are really excited about this collaboration with Collins Aerospace and the US Navy and look forward to follow the ship on its journey around the world"
