چکیده
In this review we consider the important future of synthetic fuel, dimethyl ether (DME). We compare DME to two alternatives [oxymethylene (OME x ) and diesel through Fischer-Tropsch (FT) reactions]. Finally, explore a range methodologies processes for synthesis DME. is an alternative fuel use in compression ignition (CI) engines may be produced from waste feedstocks, thereby avoiding new fossil carbon entering supply chain. characterised by low CO 2 , NOx particulate matter (PM) emissions. Its high cetane number means it can used CI with minimal modifications. The key creating circular fuels economy integrating multiple streams into economically environmentally sustainable Therefore, also availability nature low-carbon hydrogen production. Reliable dioxide sources are essential if utilisation become commercially viable. location plants will depend on local ecosystems ideally should co-located or near emitters energy sources. Alternative liquid considered interesting medium term, while renewable electricity as reliable long-term solutions transport sector. carrier which able store at times power generation. chemistry individual steps within chain generally well known usually relies cheap Earth-abundant metal catalysts. thermodynamics these well-characterised. So overcoming challenge now expertise chemical engineers put fundamentals commercial practice. It that whole systems approach adopted interventions have detrimental unintended consequences unless close monitoring applied. This shows production has been achieved great promise, there considerable effort needed reach true net zero emissions sector, particularly long-haul road use, require timescales.

Engineering a Sustainable and Economically Active Future without Fossil Fuels
The need for mankind to make the transition from a global civilisation powered by fossil fuels, to one powered by non-polluting sources of energy, is at last beginning to impinge on public awareness, now that the science of climate change is becoming established. Unfortunately, obfuscation and procrastination still exists, impeding progress to sustainability as vested interests are increasingly...

متن کاملPoly (Ether Ether Ketone) Based Anion Exchange Membrane for Solid Alkaline Fuel Cell: A Review
Solid alkaline fuel cell is employed by polymer anion exchange membrane (AEM) that is permeable to hydroxide ion. A number of polymers have been proposed for AEM which include polysulfone (PSF), poly (phenylene oxide) (PPO), and poly (ether ether ketone) (PEEK). The purpose of this paper was to conduct a critical review on the development of PEEK polymer as AEM, particu...
متن کاملThe future of oil: unconventional fossil fuels.
Unconventional fossil hydrocarbons fall into two categories: resource plays and conversion-sourced hydrocarbons. Resource plays involve the production of accumulations of solid, liquid or gaseous hydro-carbons that have been generated over geological time from organic matter in source rocks. The character of these hydrocarbons may have been modified subsequently, especially in the case of solid...
