Optical Spray Investigations on OME3-5 in a Constant Volume High Pressure Chamber
Synthetic fuels generated with surplus renewable electricity, water and captured CO2, so called E-fuels, offer the possibility to easily store excess energy over long periods of time. Therefore, the ALIGN-CCUS-project seeks to use them for power-generation and as a fuel for the transport-sector. Polyoxymethylene-dimethyl-ethers (POMDMEs, short: OME) are promising E-fuels for passenger-car applications. Their molecular structure is CH3-O-(CH2O)n-CH3. For passenger-car applications, OME-mixtures with n between 3 and 5 seem most suitable, as the mixture is liquid under normal ambient conditions, offers a high cetane-number and sufficient lubricity. Their high flash-point, low toxicity and good miscibility with conventional diesel-fuel also may ease their market-introduction.
