Emission-free Shipping

A breakthrough in reducing traffic-related air pollution: Lowering greenhouse gas emissions by 97 percent while achieving the highest energy efficiency is the goal of the European innovation project HyMethShip. The budget is 9.2 million euros. The project was launched in July 2018 and will last three years and will be completed by end of 2021.

Innovative System

The HyMethShip system innovatively combines a membrane reactor, a CO2 capture system, a storage system for CO2 and methanol, as well as a hydrogen-fuelled combustion engine into one system. The new concept allows for a closed CO2 loop ship propulsion system while maintaining the reliability of well-established marine engine technology. The system will be demonstrated onshore at full scale.

Excellent Consortium

The highly interdisciplinary HyMethShip consortium is composed of 13 partners from 6 different EU countries, bringing together all relevant players along the entire value chain. The high share of industry partners guarantees that the concept will be introduced to the market and become established there.

HyMethShip System

HyMethShip system innovatively combines a membrane reactor, a CO2 capture system, a storage system for CO2 and methanol as well as a hydrogen-fueled combustion engine into one system. The proposed solution reforms methanol to hydrogen, which is then burned in a conventional reciprocating engine that has been upgraded to operate with multiple fuel types and specially optimized for hydrogen use. The drastic CO2 reduction is the result of using renewable methanol as the energy carrier and implementing pre-combustion CO2 capture and storage on the ship. The renewable methanol fuel bunkered on the ship is ideally produced on-shore from the captured CO2, thus closing the CO2 loop of the ship propulsion system.

The HyMethShip project will undertake risk and safety assessments to ensure that the system fulfills safety requirements for on-board use and that its safety is at least equivalent to that of conventional ship fuel and propulsion systems. It will also take into account the rules and regulations under development for low flashpoint fuels and is expected to contribute to regulatory development in this area.
The cost effectiveness of the system for different ship types, applications and use cases will also be assessed. For medium and long-distance waterborne transportation, the HyMethShip concept is considered to be the best approach available that achieves this level of CO2 reduction and is economically feasible. Developing this solution can help the European shipping industry maintain its global advantage as a producer of technically advanced ships and equipment.

The innovation potential and the extent to which the project surpasses the current state of technology is excellent. HyMethShip optimizes and implements technologies that have never been used in shipping to date and have the potential to eliminate sulfur and CO2 emissions.

Through this multi-million euros project, Graz and Graz University of Technology are once again in the limelight as the international center of modern large engine research. At the interface between fundamental and applied research, the LEC and its top-class partners from science and business are taking a quantum leap to the next generation of large engines. This will bring the industry a lot closer to implementing environmentally friendly engine technology.

The proposed concept is a potential way to store large amounts of renewable energy over a long period of time and to have de facto emission-free ship propulsion. In theory and on a laboratory scale, the concept works. In the next step, a demonstrator will be built to optimize the system and the technological building blocks. The challenge lies in the scaling and interaction of the individual technological components.

On the one hand, all currently imaginable solutions require a completely new system, from the production of the energy carrier, to its distribution, to the fueling process and on-board storage, and finally to energy use. On the other hand, challenging safety issues must be resolved and certified in elaborate approval procedures. A complex ecosystem of partners must recognize sufficient advantages and join forces in a partner network. The HyMethShip consortium shows that this is possible.
