Aegir - Ammonia electric marine power for GHG emission reduction
As international shipping is a significant greenhouse gas emitter - if counted as a country, it would be on a ca. sixth place of energy-related CO2 emissions - the international maritime organization issued a strategy envisaging a 60 % reduction in the greenhouse gas emissions from international shipping by 2050 and a complete phase out of CO2 emissions by 2100. The only way to reach these targets is by wide-scale implementation of low- and zero-emission solutions within the maritime transport sector. This is the focus of the Aegir project.
The overall target of the Aegir project is to develop, test and evaluate an environmentally friendly technological solution to power large marine vessels by using green ammonia as primary fuel. The project has four main objectives:
1. Design the concept for an electric ammonia fueled ship with an efficiency over 50%.
2. Demonstrate a reduction of greenhouse gas emissions by 90% compared to current state-of-the-art liquefied natural gas fueled marine engines through a well-to-propeller analysis.
3. Experimentally validate three key enabling technologies for the integrated concept.
4. Provide a concept study to identify potential scale up issues
AEGIR proposes a unique fuel cell and membrane-based system for efficient conversion of green ammonia to electrical energy. In this concept, ammonia is (i) cracked to H2 and N2 using a solid oxide fuel cell; (ii) H2 is extracted and purified using a proton conducting electrochemical membrane; and (iii) converted to electricity using a polymer exchange membrane fuel cell. By combining these three technologies, AEGIR aims at developing an ammonia-fueled ship propulsion system that offers high efficiency in combination with a low total system volume and weight, which is the key innovation of the project. Furthermore, the concept avoids emissions of NOx and allows for a drastic reduction of CO2 emissions; the product of the fuel cell electricity process is water.
The project will design the integrated concept, experimentally validate the three key enabling technologies, demonstrate a reduction of greenhouse gas emissions by 90% compared to current state in a well-to-propeller analysis, and identify potential scale up issues for a 20 MW maritime system in a concept study.
The industrial partners and Advisory Board members (comprising several international shipping companies) will be able to transfer the project outcome to even higher application levels after end of the project.
