Holistic Energy Management & Optimisation System – HEMOS

THIS PROJECT AIMSO TO HOLISTICALLY REDESIGN THE SHIP’S HEAT ENERGY MANAGEMENT SYSTEM WITH THE AID OF DYNAMIC OPTIMISATION ALGORITHMS.

Economic considerations and environmental restrictions drive the demand for better energy management onboard. Depending on the ship type, about 40–50% of the heat energy is currently disposed to the environment. Most of the lost heat energy is low (< 100 °C), which is more challenging to convert into valuable energy such as electricity. In port areas, ships are one of the largest air polluters (CO2, SOx, NOx, particles). The HEMOS project aims to develop and verify a holistic and dynamic on-demand heat energy system concept to utilise the otherwise lost waste heat energy.
  • We will map and analyse all significant ship heat sources, consumers and losses.

     

  • We will develop a simulation tool capable of dynamically assessing and optimising the vessel’s energy demand and the system energy fluxes.

Holistic energy management & optimisation system

Economic considerations and environmental restrictions drive the demand for better energy management onboard. HEMOS project aims to redesign the ship heat energy management system with the aid of dynamic optimisation algorithms.

CONTEXT
The global shipping sector currently contributes about 2.5–3% to global CO2 emissions. Within the EU, the maritime sector makes up about 14% of greenhouse gas emissions from the transportation industry.  In port areas, ships are one of the largest air polluters (CO2, Sox, NOx, particles). IMO introduced a new Energy Efficiency eXisting ship Index (EEXI) that poses a challenge for ship owners. Significant increases in fuel prices put additional stress on ship owners to find options to reduce energy expenses. Follow link for further HEMOS information.
