Ford is leading a €3.5 million research project to investigate the use of alternative fuels that could offer the power and performance of modern petrol and diesel engines with environmental benefits comparable to an electric car.
The German government is co-funding the three-year project that will test the first cars to run on dimethyl ether (DME), commonly used as a non-toxic propellant in aerosol spray gas, and oxymethylene ether (OME1), a liquid usually used as a solvent in the chemical industry.
Both ethers, which will power cars based on the Ford Mondeo, offer the potential for low particulate emissions and enhanced fuel efficiency. They can be generated from fossil natural gas or bio-gas or through a sophisticated process called power-to-liquid that uses renewable sources such as solar or wind power together with CO2 captured from the air.
Both DME and OME1 produce almost no particulates, and also share characteristics with diesel fuel that are expected to make conversion of diesel engines possible with comparable performance. It is estimated that DME from renewable energy sources could offer emissions as low as 3g/km which today would mean just a five percent BIK tax band for the current 2015/16 tax year.
“The CO2 produced by a car powered by DME from renewable sources could be comparable to the amount generated by a marathon runner covering the same distance – but with performance similar to a diesel powered vehicle,” said Werner Willems, technical specialist, powertrain combustion systems, Ford of Europe. “This is a project that could help place vehicles with a significantly reduced carbon dioxide and particulate emissions on the market at affordable costs.”
This new technology is being investigated in a parallel project together with RWTH Aachen University researching the viability of different DME generation methods, looking at conversion efficiency, estimated fuel prices and infrastructure aspects.
“The growth of the world’s population is putting ever-increasing demands on energy and especially fossil fuels. Alternative, renewable fuels like methyl ethers will play a pivotal role in the future,” said Andreas Schamel, Ford’s director Global Powertrain Research & Advanced Engineering. “DME is safe, burns cleaner than conventional diesel, and most importantly is versatile. The energy generated from solar, wind and other renewables can be stored within the fuel itself, and this enables DME and OME1 to be used across a range of applications.”
