Project

The main objective of this project is to provide a detailed feasibility study of the economy, maturity and technical challenges in changing diesel gen-sets of the offshore service fleets with a hybrid battery and fuel cell powered units. Currently, these ships are supplied with 2-4 high velocity 4-stroke diesel motors with the size 1-6MW that consume low-sulfur diesel oil. These ships normally sail with 14 day return cycles and therefore they should be equipped with energy stored for at least 14 days.

This project includes modelling, designing and testing of a 150 kW solid-oxide electrolysis (SOE) system for renewable hydrogen production. The produced hydrogen can be used as a component for future green electro-fuels like ammonia or methanol.

The SOC stacks will be operated by the novel AC:DC control method which enables dynamic hydrogen production due to fluctuating electricity production from wind turbines.

The AC:DC method requires bi-directional power flow of the stacks and dedicated power electronic converters will therefore be developed in this project as well.

When the project is successfully completed, the consortium will have demonstrated manufacturing and operation of a power-to-X plant with AC:DC operation technology. This is an important milestone on the path for megawatt production.

The shipping industry's plans to replace fossil fuels with green fuels have several well-described climate and environmental benefits, but far less well-studied are the possible environmental risks linked to a large-scale use of green fuels in ships. Sufficient knowledge of the physical and chemical properties, toxicity to the environment, as well as dispersion and degradation dynamics of the green fuels in the environment are therefore fundamental prerequisites for the shipping industry to implement the green transition with minimal risk of simply replacing one problem with another.

In this project, we will carry out the first in-depth mapping and environmental risk assessment of potential derived environmental effects that may arise from both emissions to the atmosphere and discharges to the marine environment from these green marine fuels. The project includes, among other things, a thorough review of the properties of the green fuels in both air and water, experimental studies on the impact on aquatic organisms, natural degradation mechanisms, the spread in both the atmosphere and marine environment during normal operation and in the event of accidents/spills, as well as life cycle assessment (LCA).

The project aims to facilitate the transition from fossil fuels to greener energy sources in Danish ferry shipping. The new and rebuilt ferries have, among other things, increased automation and innovative changes, which change the roles of crew members and require different skills.
A tailored method for job requirement analysis will be developed, with the Molslinjen as
a test platform, to identify competence gaps and optimize the distribution of tasks between people and technology.
The goal is to strengthen the ability of crews to handle the increased complexity of modern shipping and promote efficiency in the industry.

“Green Transitions in Port of Aalborg” is a collaboration between the Port of Aalborg and Aalborg University Business School. Both organizations share from different angles—practice and research—the interest in green transitions; that is, how business operations and strategies can be designed such that they ensure an ecologically sustainable economy. As business operations vary widely, this strategic initiative comprises three main foci, looking at business operations within the port, at how the port interacts with its external environment, and at the port as one player in the broader regional environment (i.e., Greater Aalborg), always through the lens of identifying and solving problems in relation to green transitions.

In this project, we will conduct the first in-depth mapping and environmental risk assessment of potential secondary environmental effects that may arise from both emissions to the atmosphere and discharges to the marine environment from these CO2 neutral marine fuels. The project includes a thorough review of the properties of CO2 neutral fuels in both air and water, experimental studies of the impact on aquatic organisms, natural degradation mechanisms, their dispersion in both the atmosphere and the marine environment during normal operation and accidents/spillages, and life cycle assessment (LCA).

CAPeX will develop and implement a new powerful Materials Acceleration Platform (MAP) for rapid development of materials and a closed-loop data infrastructure where new catalysts and other materials for power-to-X are discovered, synthesized and designed directly for their intended operating conditions.

The objective of GreenHyScale is to pave the way for large scale deployment of electrolysis both onshore and offshore
