Periodic Reporting for period 1 - HELENUS (High Efficiency Low Emission Nautical Solid Oxide Fuel Cell)
Reporting period: 2022-07-01 to 2023-12-31
The HELENUS project will develop and demonstrate a 500 kW solid oxide fuel cell (SOFC) in an MSC World Europa class ocean cruise vessel. The SOFC will be fully integrated into the ship’s design, producing both electricity and high-grade heat in combined heat and power mode. The project aims to achieve a Technology Readiness Level (TRL) of 7 by its end, with plans for extended field testing to reach TRL8 immediately following the project. If successful, this technology could be scaled up to as much as 20 MW, leading to over 23% total fuel savings compared to state-of-the-art energy systems with only internal combustion engines (ICEs). Furthermore, the project will demonstrate scalability of the SOFC technology to 10 MW and beyond, with further potential applications in dredging and offshore vessels. The fuel-flexibility of the SOFC system with low carbon maritime fuels will also be demonstrated, enabling robustness of the solution to future energy transitions,
The HELENUS consortium brings together diverse stakeholders across the value chain, from technology development to field implementation, to drive innovation and commercialization. The project will create a roadmap to a decarbonized future, fostering innovation and significantly boosting the competitiveness of the EU maritime industry. The project is described in more detail on our website: www.helenus.eu
Furthermore, a parallel effort on assessing the applicability and scalability of the developed solution has also begun. Initial reduced-order models and benchmaks for SOFC transient controls were developed and established to optimize their performance in dynamic operating conditions. Benchmark concepts for cruise ship, dredging, and offshore vessels were defined over which the impact of the SOFC system will be subsequently assessed. The software tool to perform a Lifecycle Performance Analysis (LCPA) of different SOFC scaling solutions over the various applications, along with corresponding KPIs to compare the scenarios were also defined.
Finally, a set of alternative fuels was chosen by the consortium for investigation of fuel-flexibility of the SOFC system over simulations and experimental testing.
