“…At present, the direct synthesis of formaldehyde and methanol by Oestrich [104] and the endothermic dehydrogenation of methanol as proposed by Ouda et al [105,106] are challenging research topics. Process analysis utilizes Aspen Plus or ChemCad simulations and has been performed by various research groups [105][106][107][108][109][110][111][112][113]. An important finding of process analyses is that the high power consumption entailed by Oxymethylenether (OME) synthesis requires special heat management.…”

Achieving the CO2 reduction targets for 2050 requires extensive measures being undertaken in all sectors. In contrast to energy generation, the transport sector has not yet been able to achieve a substantive reduction in CO2 emissions. Measures for the ever more pressing reduction in CO2 emissions from transportation include the increased use of electric vehicles powered by batteries or fuel cells. The use of fuel cells requires the production of hydrogen and the establishment of a corresponding hydrogen production system and associated infrastructure. Synthetic fuels made using carbon dioxide and sustainably-produced hydrogen can be used in the existing infrastructure and will reach the extant vehicle fleet in the medium term. All three options require a major expansion of the generation capacities for renewable electricity. Moreover, various options for road freight transport with light duty vehicles (LDVs) and heavy duty vehicles (HDVs) are analyzed and compared. In addition to efficiency throughout the entire value chain, well-to-wheel efficiency and also other aspects play an important role in this comparison. These include: (a) the possibility of large-scale energy storage in the sense of so-called ‘sector coupling’, which is offered only by hydrogen and synthetic energy sources; (b) the use of the existing fueling station infrastructure and the applicability of the new technology on the existing fleet; (c) fulfilling the power and range requirements of the long-distance road transport.

Poly(oxymethylene) ethers (OME) are synthetic diesel fuels, which show extremely low soot formation during combustions. They are heavily discussed as future climate-friendly alternative to fossil diesel fuels, e.g. via an efuel route. To put this discussion on solid grounds, it is important to look at how OME are actually produced. This paper given an overview of the technology for the production of OME. The raw materials and the roles of the intermediates (synthesis gas, methanol, formaldehyde, dimethyl ether, and trioxane) in the valued added chain toward OME are explained. Technically feasible process concepts are described and assessed regarding economics and energetic efficiency. Current and future research directions for finding novel, improved production routes are discussed, before the paper is concluded.

“…Investment costs for the required water electrolysis capacity of 3.7 GW el were estimated from [78] -21) For the synthesis of oxymethylene ether OME-4 with a sum formula of CH 3 O(CH 2 O) 4 CH 3 a theoretical ratio of 7:6 would be required. However, since OME are produced from methanol calculation was done with methanol stoichiometry and recovery of hydrogen was assessed from formaldehyde production downstream separately [79,80].…”

Within Carbon2Chem® the presented subproject focused on oxymethylene ethers (OME) as possible diesel fuel components. Six different scenarios for CO2 emission reduction in steel mills were calculated, in four of which methanol is generated as an OME intermediate from steel mill gases. Potential synergies in raw material and energy streams of the coupled processes were identified. Shared process streams and equipment could lead to savings in capital and operational expenditure. CO2 reduction volumes and avoidance costs were calculated for the six scenarios. If coupled with methanol production, natural gas‐based direct reduced iron processes offer the chance for quantitative CO2 emission reduction at the lowest CO2 avoidance costs. Energy required for this process could be co‐fed, e.g., as renewable electricity.
