Alfa Laval introduces multi-source waste heat recovery system

Launching in April, the E-PowerPack is a self-contained solution that can generate electricity from many different heat sources on board. These include exhaust gas waste heat, which accounts for 50% of the energy from combusted fuel, but also liquid sources at lower temperatures, such as engine jacket water.

On vessels where moving to low-sulphur fuel has created a surplus of steam, the E-PowerPack will transform the excess into a free source of power. Going forward, the E-PowerPack will also be vital as energy recovery becomes key in transitioning to green methanol and ammonia. Alfa Laval says the system improves EEDI/EEXI and CII, thus supporting compliance and a more favourable rating while paying itself back in as little as two to three years.

“Alfa Laval is pursuing a wide range of technologies to support decarbonization, both independently and with partners,” says Lars Skytte Jørgensen, Vice President Technology Development, Energy Systems, Alfa Laval Marine Division. “Fuel cells and many other innovations are in the pipeline, but the first critical step is to leverage the existing energy on board. The E‑PowerPack does that in a revolutionary way, while building on Alfa Laval’s many decades of waste heat recovery experience.”

The E-PowerPack will launch on 5 April 2022 with a special webinar broadcast from the Alfa Laval Test & Training Centre. During the webinar, Alfa Laval will describe the product and its use of ORC technology to turn waste heat into clean electricity.
