Summary

Future powertrain technologies will be measured against five criteria: I. CO₂ neutrality, II. sustainability, III. exhaust emissions, IV. cost-effectiveness and V. functionality. Criteria I. to III. are statutory requirements that take priority and lay the foundations for sustainability. This paper assesses the potential of different powertrain technologies to maintain a clean environment. Methanol and DME can be synthesised directly from CO₂ as a carbon source and from sustainably produced H2. They are valuable sources of energy but toxicity and high vapour pressure at ambient temperatures limit their use as fuels. Their conversion to non-toxic or liquid fuels removes these limitations. The resulting fuels are CO₂-neutral and sustainable. Ether-based fuels with C1 building blocks that contain no C-C bonds are a particularly effective means of minimising emissions with less complex exhaust aftertreatment.
