ECOMARINE project will develop innovative Waste Heat Recovery (WHR) system for PEMFC for marine applications. The developed technology will be suitable for a range of vessels as new built systems or retrofit to deliver 20% increase in on-board efficiency compared to state-of-the-art power systems. The improvements will also result in reduced operational expenses (OPEX) and return on investment (ROI) for hydrogen-based power systems.
The aim is to recover and recycle waste energy of proton exchange membrane fuel cell (PEMFC) system using active techniques based on absorption cooling systems. The ultimate goal is to improve the efficiency of PEMFC power system by at least 20% through combined heat power (CHP) system. The energy will be recovered by a combination of strategies, such as: recovering waste heat energy by the combination of an absorption cycle to recover energy from the cooling system of the fuel cell, minimizing energy losses of the overall system by smart energy monitoring, control, and distribution strategies, and minimizing energy losses through digital twin and modular vessel route planner, and by minimizing losses of fuel storage. The recovered energy will be used onboard for HVAC, sanitary water heating, preheating of fuel cell inputs or for other purposes. For cold regions offshore operations, this waste energy will also be used in the vessel’s winterization solutions, such as for fixed automated spray technology (FAST) for anti/de-icing fluids, hot water sprays, hot bubbling system for ballast tanks, hot water flooring to minimize accumulations, and other solutions. The following are therefore project objectives:
i. To achieve 20 % efficiency improvement by combined heat and power (CHP) cycle,
ii. To develop proof of concept demonstrators that are applicable to maritime and land transport to demonstrate improved energy performance and operational efficiency of the system.
iii. To demonstrate significant reduction in GHG emissions from waterborne transport.
iv. To enable the timely on-board application of innovative and green solutions for energy transformation that require significantly higher volumes for storage and equipment.
v. To demonstrate the potential for efficiency improvement by optimising various systems on board marine vessels such as: monitoring, control, power management solution, implementation of digital twins and software solutions.
vi. To demonstrate reduction in fuel consumption, by augmenting HVAC, winterization and other potential
vii. Demonstration of the system at lab scale at TRL5 to prove 20% efficiency improvement.
To achieve the project objectives there are a total of nine work packages, twenty-eight deliverables, and seven milestones in this project.
