E-Power Pack can convert waste heat from many sources on board into electricity

Alfa Laval is about to launch the E-PowerPack, a stand-alone solution that can generate electricity from many different heat sources on board ships, using Organic Rankine Cycle (ORC) technology.

This is not only waste heat from exhaust gases, which accounts for 50% of the energy from the fuel burned, but also liquid sources at lower temperatures, such as engine jacket water .

By converting waste heat directly into electrical energy, the E-PowerPack reduces fuel consumption and CO2 emissions.

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

Whatever fuels they run on today, fleets can use the E-PowerPack to reduce fuel consumption, emissions and costs. On vessels where switching to low sulfur fuel has created excess steam, the E-PowerPack will turn the excess into a free source of power.

“The versatility and fuel savings will make the E-PowerPack an easy choice for shipowners, who can use it to improve a vessel’s energy efficiency index and carbon intensity indicator,” says Danny Ingemann, global product sales manager at Alfa Laval. “On a broader level, this will be a game-changer in achieving the industry’s common goal of net zero carbon.”

In the future, according to Alfa Laval, the E-PowerPack will also be vital as energy recovery becomes essential in the transition to green methanol and ammonia.

“Savings that offset fuel costs are only part of the picture, since methanol and ammonia are both more expensive and less energy intensive,” says Ingemann. “For the amount of fuel they carry to be feasible, ships will have to use all the energy contained in methanol and ammonia. The E-PowerPack will be an essential element in achieving energy balance.

The E-PowerPack will be launched on April 5 with a special webinar broadcast from the Alfa Laval Test and Training Center.
