The Apollo project will mature and demonstrate in operational environment, the disruptive installation of a dual fuel ammonia engine in an offshore supply vessel to ammonia operation reducing emissions by 70%. The project is developed to closely answer the HORIZON-CL5-2022-D5-01-04 topic of transformation of the existing fleet towards greener operations through retrofitting (ZEWT Partnership). The specific objectives include: 1) Successful large-scale demonstration of the use of dual-fuel ICE (ammonia-based) in an existing vessel; 2) Complete first classification under DNV “Gas fuelled, Ammonia”; 3) 70% reduction of CO2 emissions and NOx emissions below 2.4 g/kWh from vessel operations; 4) Complete retrofitting solution to operate on ammonia, through development of safe ammonia storage and operation, including both deck load or below deck tanks; 5) Demonstrate the retrofit in replicators in other two vessels with different use (dredging and offshore construction) and validate feasibility for scaling; 6) Support to the expansion of the ammonia bunkering network in the North Sea and beyond, obtain 100% green ammonia for the project’s needs; 7) Validated business case for ammonia as a ship fuel with operational expenditures <130% from baseline by project end. The Apollo solution will be flexible, so ship owners, ship designers, shipyards, classification agencies and insurance companies can quickly adopt it into their decision-making processes. The consortium will prepare the business case for ammonia in the waterborne transport sector, from the production of green ammonia to its use in different ships on the European scale.

Floating offshore wind is still a nascent technology and its LCOE is substantially higher than onshore and bottom-fixed offshore wind, and thus requires to be drastically reduced. The COREWIND project aims to achieve significant cost reductions and enhance performance of floating wind technology through the research and optimization of mooring and anchoring systems and dynamic cables. These enhancements arisen within the project will be validated by means of simulations and experimental testing both in the wave basin tanks and the wind tunnel by taking as reference two concrete-based floater concepts (semi-submersible and spar) supporting large wind turbines (15 MW), installed at water depths greater than 40 m and 90 m for the semi-submersible and spar concept, respectively. Special focus is given to develop and validate innovative solutions to improve installation techniques and operation and maintenance (O&M) activities. They will prove the benefits of concrete structures to substantially reduce the LCOE by at least15% compared to the baseline case of bottom-fixed offshore wind, both in terms of CAPEX and OPEX. Additionally, the project will provide guidelines and best design practices, as well as open data models to accelerate the further development of concrete-based semi-submersible and spar FOWTs, based on findings from innovative cost-effective and reliable solutions for the aforementioned key aspects. It is aimed that the resulting recommendations will facilitate the cost-competitiveness of floating offshore wind energy, reducing risks and uncertainties and contributing to lower LCOE estimates. COREWIND aims to strength the European Leadership on wind power technology (and specially floating). To do so, the project consortium has been designed to ensure proper collaboration between all stakeholders (users, developers, suppliers, academia, etc.) which is essential to accelerate commercialization of the innovations carried out in the project.
