For a long time, the search has been on to find a fuel for marine compression engines that is environmentally friendly, stores easily and transported simply. This has been realized in dimethyl ether (DME), a fuel that can be used as a direct substitute for diesel. Unlike compressed natural gas (CNG) or liquid natural gas (LNG), most importantly, DME can be used in compression engines, which substantially impacts the potential applications of this fuel over LNG, CNG, ethanol or methanol. It does not require a particulate filter or a selective catalytic reduction ("SCR") system, so engines are much cheaper and less complicated than standard diesel engines. They are exempt from the filter cleaning and the "add blue" protocols of modern diesel engines. All of this justifies the commencement of work on new technologies for DME production from natural gas.DME is conventionally produced from methane and a biomass feedstocks, which are not net carbon neutral. There are scare few technologies that can direct convert CO2 or natural gas to DME, in high yields and selectivities. The recent hybrid catalytic platform that we have evolved has demonstrated highly effective CO2 storage for subsequently utilisation (CCU) in fuels and polymers. This project will build on these latest findings to design a catalytic platform for the direct conversion of CO2 to DME, leading to the development of clean marine fuels. The strategy aims to reduce the CO2 intensity of international shipping by at least 40% by 2030 and to cut total GHG emissions by at least 50% by 2050, both relative to a 2008 baseline.

长期以来，人们一直在寻找一种环保、易于储存和运输的船用压缩发动机燃料。这已经在二甲醚（DME）中实现了，二甲醚是一种可以直接替代柴油的燃料。与压缩天然气（CNG）或液化天然气（LNG）不同，最重要的是，二甲醚可以用于压缩发动机，这大大影响了这种燃料在液化天然气、CNG、乙醇或甲醇上的潜在应用。它不需要微粒过滤器或选择性催化还原（“SCR”）系统，因此发动机比标准柴油发动机便宜得多，也不那么复杂。它们免除了现代柴油发动机的过滤器清洗和“添加蓝色”协议。所有这些都证明了开始研究从天然气中生产二甲醚的新技术是合理的。二甲醚通常由甲烷和生物质原料生产，它们不是净碳中性的。很少有技术可以将二氧化碳或天然气直接转化为二甲醚，而且产量高，选择性好。我们最近开发的混合催化平台已经证明了燃料和聚合物中后续利用（CCU）的高效二氧化碳储存。该项目将以这些最新发现为基础，设计一个直接将二氧化碳转化为二甲醚的催化平台，从而开发清洁的海洋燃料。该战略的目标是到2030年将国际航运的二氧化碳强度降低至少40%，到2050年将温室气体排放总量减少至少50%，两者都相对于2008年的基线。
