Project

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 project investigates the green transition to fisheries and fisheries technologies that are sustainable in a life cycle perspective. The project intends to combine knowledge on fisheries policy, management, and technology with data and methods from industrial ecology and product environmental assessment to obtain a deeper and multidimensional understanding of the impact of fisheries and improve decision making for stakeholders and policymakers in this sector.

The project has two key objectives: 1) to develop new methods that accurately assess the climate impacts of fisheries accounting for constraints in supply, 2) to identify the trade-offs between fisheries practices that promote sustainable harvesting of stocks and the more recent drive to fish in a climate-friendly way.

The project combines expertise, tools, and methods from three different research domains: life cycle assessment, fishing technology, marine governance.

Automation plays a key role in reducing CO2 emissions in shipping, yet human sensory contributions are often overlooked and understudied. The project studies how human senses and sensor technologies interact in decision-making from an anthropological perspective.

Through five technological projects, SLGreen aims to develop digital tools to reduce fuel consumption in Danish shipping, improve ship performance, optimize hull maintenance, monitor engine condition and implement remote navigation.
The transversal anthropological project, Senses & Sensors, will add an analysis of human competencies and explore dynamics in the execution of the projects.
SLGreen is supported by the Innovation Fund Denmark, the Danish Maritime Foundation and the Lauritzen Foundation.

OLAMUR will demonstrate and promote multi-use low trophic aquaculture (MU-LTA) in both low and high salinity offshore waters, bringing together state-of-the- art practices in MU-LTA and key industry partners, achieving at least TRL7 and paving the way for a low- impact and low-carbon seafood industry.

The project focuses on supporting the Danish strategy on decarbonization by means of accelerating the implementation and scaling of green Power-to-X (PtX) technologies in Denmark. A pivotal part in such acceleration is to build well- functioning and safe infrastructures of storage, handling, and bunkering in Danish ports, as these play a key part as future green energy hubs. The project apply techno -anthropological theories and methodologies to explore and unpack possible safety concerns and ethical controversies within social acceptance among stakeholders across the PtX value chain in two Danish ports: Rønne and Aarhus. Based on this, the project develops a handbook with guidelines and tools on how to establish social agreements on safety in PtX projects. Thus, the project taps into topics in the themed area of green research and technology development, i.e. developing new energy systems while also understanding societal consequences of these, and drafting tools.
supporting this shift.

Ferries are responsible for 0.8 million tons of greenhouse gas emission annually in Denmark and often sail close to cities where they add to the already critical air pollution levels. This holds especially true for small Danish municipalities, as diesel-driven ferries contribute up to 20 % to their total global warming contribution. Therefore, fully electric powered ferries are taking centre stage in Denmark. However, the current wide use of synthetic refrigerants (and their leaks into the atmosphere) in the maritime sector leads even 100 % electricity-powered ships not to be actually greenhouse gas emission free. In addition, currently the driving range of fully electric powered ferries is penalized due to the lack of an optimized heat pump system layout, suitable battery thermal management strategy and appropriate waste heat recovery approaches.

The objective of the ECO2-ferries project is to develop the first heat pump being completely tailored to 100 % electricity-powered ferries. The use of CO2 as a natural (i.e. future-proof) refrigerant of the heat pump will finally lead 100 % electricity-powered ferries to be actually greenhouse gas emission free ships. In addition, CO2 will allow for a compact heat pump and high safety levels (i.e. non-flammable and non-toxic). High energy performance will be guaranteed by the implementation of (i) an optimized system layout, (ii) a proper battery thermal management approach, (iii) a suitable heat recovery technique as well as (iv) an effective and robust overall control strategy.

The ECO2-ferries project will involve the University of Southern Denmark, Odense Maritime Technology and Marstal Navigationsskole as project partners and Danske Maritime, Danfoss A/S, BCOOL A/S, Danish Technological Institute, Ærø municipality and Ærøfærgerne as project supporters. The project has received funding from Den Danske Maritime Fond.

The shipping industry is responsible for around 3% of global greenhouse gas emissions, and this is expected to increase as global trade and shipping activity continues to grow. As such, reducing emissions from shipping is an important part of global efforts to tackle climate change.

In the project, DTU will develop tools that can help a bulk shipping company predict market trends so they can deliver the right capacity to the right region. Furthermore, tools will be developed to plan a coherent route plan to ensure that new orders are available at the final destination to avoid deadheading.

MAN Energy Solutions is developing a new two-stroke dual fuel natural gas-diesel marine engine based on new premixed combustion technology. The current project aims to study the methane slip which is one of the main challenges of the premixed technology. The pilot diesel fuel injection parameters will be optimized to obtain higher efficiency and lower emissions.
