The decarbonisation targets of the shipping sector by IMO are extremely challenging and require active measures as soon as possible. ENGIMMONIA comes with solutions that focus on two main pillars: i) promote the global introduction of alternative fuels (ammonia), ii) transfer to maritime sector clean energy technologies robustly demonstrated for terrestrial application (e.g. Waste heat recovery, renewables etc). ENGIMMONIA will indeed study the benefits of using a carbon-free fuel like ammonia (that in any case could have a GHG impact due to N2O emissions that should be properly treated by an EATS to be developed in ENGIMMONIA under AUTH/DTU supervision) in vessel engines also coupling its benefits/performances with other clean energy technologies like: (1) waste heat recovery solutions based on ORC and adsorption chiller for the production of electricity and space cooling respectively, (2) renewables integration on board thanks to the installation of PV composite surface easily installable on vessel structural parts , (3) on board fuel/energy/heat management optimization via real time Energy Mangement System; towards the creation of ENGIMMONIA polygeneration energy hub. Targeting long term full decarbonization of shipping sector, ENGIMMONIA will capitalize previous R&D initiatives that already tested some of these technologies for terrestrial application, moving them to marine sector also from a regulatory/business point of view under RINA coordination, as a naval classification body. To do so technologies will be demonstrated at TRL>5 in real scale engines (MAN) and on board of three vessels: an oil tanker (FAMOUS), a shipping vessel (DANAOS) and a ferry (ANEK) thus proving their replicability on board of different type of vessels. To guarantee ENGIMMONIA innovations wide acceptance, maritime sector’s key players are involved (C-JOB, MAN, RINA-C etc.) while other will interact as stakeholders, also supporting IMO and IACS initiatives at policy/regulatory level.

DT4GS is aimed at delivering an “Open Digital Twin Framework” for both shipping companies and the broader waterborne industry actors to tap into new opportunities made available through the use of Digital Twins(DTs). The project will enable shipping stakeholders to embrace the full spectrum of DT innovations to support smart green shipping in the upgrade of existing ships and new vessels. DT4GS will cover the full ship lifecycle by embracing federation of DT applications as well as utilising DTLF policies and related shared-dataspace developments for the sector. DT4GS applications will focus on shipping companies but will also provide decarbonisation decision-support system for shipyards, equipment manufacturers, port authorities and operators, river commissions, classification societies, energy companies and transport/corridor infrastructure companies. DT4GS’s objectives are to: 1. Support shipping companies in achieving up to 20% reduction in CO2e with a 2026 horizon, by developing and deploying real-time configurable DTs for ship and fleet operational performance optimisation in 4 Living Labs involving shipping companies, with different vessel types, and establishing fully validated industry services for Green Shipping Operational Optimisation DTs expected to be adopted by 1000+ ships by 2030. 2. Establish a comprehensive zero-emission shipping methodology and support Virtual Testbed and Decision Support Systems that address both new builds and retrofits comprising: a. A DT4GS (Green Shipping) Dataspace for the broader shipping sector contributing to GAIA-X by establishing a core European industry resource that accelerates the green and digital transition of waterborne shipping and transport value chains. b. Simulation based solutions to retrofit ships, targeting 55% reduced CO2e reduction by 2030. c. A smart green “new-build” reference design per vessel type. d. Virtual Testbed services for reducing the cost of physical testing of GS solutions by 20%.
