This pilot project will be a big move towards the use of Dimethyl ether (DME) as a competitive and clean fuel alternative for the marine sector. Upcoming regulation of SOx, NOx, CO2 and the focus on soot emissions from the marine fleet is a challenge with current marine fuels. Engine technology for alternative fuels such as natural gas, propane, ethane and methane is under development. These fuels all have drawbacks compared to DME, especially regarding clean combustion and efficiency potential.
Some of the project outcomes will be:
- Guidelines for design of an efficient, low emission DME engine.
- Guidelines to benefit from the additional Waste Heat Recovery potential of DME.
- Optimization of DME production by combining conventional and renewable sources.
- Investigation of marine application of the estimated 10 million tons per year currently unused Chinese DME production capacity, including cost and
logistics for marine supply.
- To develop a Danish-Chinese sustainable energy collaboration to strengthen the achievement of both countries sustainable development goals.
- To strengthen the technological leadership of the Danish and Chinese Maritime Sector.
First year report
A predictive model to predict stress on piston rings by DME combustion has been developed and is being evaluated.
An optical accessible combustion chamber is being modified for DME injection.
Sophisticated impeller design tools have been developed to optimize the expander design for waste heat recovery for DME marine engines. A small-scale test system has been built and is being connected to a test engine.
A tank container system for DME storage is being evaluated and CMARI is designing and estimating cost of an aluminum tank container. The energy balance of cooled bulk tanks is evaluated and a topology optimization of a pressurized bulk tank will soon be performed.
A comprehensive investigation of biomass availability in China have made and documented in a mater thesis.
A container ship type has been chosen as case for the business case analysis and historic date data of a representative voyage, cargo and bunkering pattern will be shared when the cooperation agreement has been signed.
