The Alfa Laval E PowerPack uses Organic Rankine Cycle (ORC) technology to convert excess heat into free electrical power, making it a convenient sustainability upgrade with a measurable impact on energy efficiency. Since it runs at the low temperature of engine jacket water, your vessel can generate power continuously – from the very first minute. Adding high-temperature steam heat only increases its output, which means further fuel savings and even faster payback.

Alfa Laval E-PowerPack 200kW

Power your way to energy efficiency

  • Convert your vessel’s excess heat into free electrical power
  • Produce power at all times using low-temperature heat
  • Measurably improve your vessel’s energy efficiency
  • Reduce costs and greenhouse gas emissions by burning less fuel
  • Achieve a better Carbon Intensity Indicator (CII) and environmental profile

Built on Organic Rankine Cycle (ORC) technology, the E‑PowerPack generates free electricity from both low-temperature and high-temperature heat sources on board. Engine jacket water provides enough heat for it to run, and the power output increases when surplus steam or other heat sources are added. Where steam is readily available, a steam optimization option allows even greater output at high temperatures.

Since the E‑PowerPack reduces auxiliary engine load by up to 30%, it has a significant impact on fuel costs, greenhouse gas emissions and vessel ratings (EEDI/EEXI and CII). The produced electricity is readily available from the grid and constantly measured, which provides clear support for sustainability claims.

A single E‑PowerPack module has a net electrical output of up to 200 kW, and multiple units can be combined to form a larger system.

How it works

Organic Rankine Cycle (ORC) technology  - Alfa Laval E-PowerPack


The E-PowerPack uses Organic Rankine Cycle (ORC) technology to turn waste heat into clean electrical power. By means of a liquid-gas phase change, it can generate power from both high-temperature and low-temperature heat sources. Please find the ORC technology explained by Mr. Dimitrios Kampanis.








Introducing the Alfa Laval E-PowerPack – a game-changing advance in marine sustainability

As the marine industry works to decarbonize, Alfa Laval is at the forefront of preparing technologies to make it happen. Now the first of many new energy solutions is coming to fruition: the Alfa Laval E-PowerPack. Able to convert waste heat directly into electrical power, the E-PowerPack reduces fuel consumption and CO2 emissions – creating a simple, cost-saving tool for complying with new sustainability requirements.
