Only the car will drink-drive in Lotus’ alcohol fuel experiment

Lotus Engineering is unveiling its latest development towards carbon neutral road transport at the 78th Geneva International Motor Show over the next week. The Lotus Exige 270E Tri-fuel is the most powerful road version yet of the Exige (0-60 mph/96 kph in 3.88 seconds, a top speed of 158 mph – and it runs on any mixture of gasoline, bioethanol and methanol. Emerging technologies will allow alcohol fuels such as methanol, already a proven internal combustion fuel, to be made synthetically from CO2 extracted from the atmosphere. An alcohol-based fuel derived renewably from atmospheric CO2 would allow society to transfer relatively easily to sustainable, carbon-neutral internal combustion. Lotus Engineering is researching the use of sustainable synthetic alcohols as potential future fuels, with technology available from Lotus for introduction in four to five years. However, the supply infrastructure investment from governments and fuel companies could take 15 to 20 years, the Norfolk company has warned. The Exige 270E Tri-fuel is part of Lotus’ research to understand the complex combustion process involved in running on mixtures of alcohol fuels and gasoline, which will be important for a successful transition from today’s fuels to the sustainable, synthetic fuels of the future. This research is just one aspect of Lotus Engineering’s ground-breaking work on environmentally- friendly vehicles. It is involved with a number of electric vehicle projects, has successfully integrated hybrid technologies into vehicles such as its EVE demonstrator and recently announced results on a collaboration with Continental Division Powertrain on the Low CO2 downsized three-cylinder engine. The research into sustainable alcohols is progressing at Lotus’ Hethel headquarters in Norfolk and involves input from the Royal Society of Chemistry’s Alternative Fuel Symposium Series, the Low Carbon Vehicles Innovation Platform, developed by the Technology Strategy Board and direct discussions with the University of Sheffield. Methanol (CH3OH) can be produced synthetically from CO2 and hydrogen. Ultimately, emerging processes to recover atmospheric CO2 will provide the required carbon that can entirely balance the CO2 emissions at the tailpipe that result from the internal combustion of synthetic methanol. The result is that a car running on synthetic methanol, such as the Exige 270E Tri-fuel would be environmentally neutral. As well as being green, the great benefit of synthetic methanol is that it would use similar engines and fuel systems to those in current cars; and synthetic methanol can be stored, transported and retailed in much the same way as today’s liquid fuels such as gasoline and diesel. Synthetic methanol also possesses properties better suited to internal combustion than today’s liquid fuels, giving improved performance and thermal efficiencies. And it is ideal for pressure-charging (turbocharging and supercharging) already being introduced by manufacturers to downsize engines in a bid to improve fuel consumption. Lotus Engineering’s Lotus Exige 270E Tri-fuel technology demonstrator illustrates how easy it is for synthetic methanol to be embraced over time as a future fuel for road transport. The Exige 270E Tri- fuel, with its supercharged 2ZZ-GE VVTL-i engine, could be the forefather of a new generation of conventionally driven cars that have the potential to be environmentally-neutral. Mike Kimberley, CEO of Group Lotus, explains: “Lotus is a world-class leader in research into a variety of alternative fuels; each has its merits and challenges and some options could be more easily implemented than others. “But while motorists want to be green, we do not want to change the culture of total freedom for the owners, who will have an extreme reluctance to spend more at the pump, or to sacrifice the performance of their cars. “At present, the motor industry is seeking a route to reduce CO2 emissions just at the tailpipe; this focus is far too narrow. A sustainable alcohol such as synthetic methanol has the potential to reduce the overall CO2 footprint of internal combustion vehicles towards zero. “Produced through CO2 recovered from the atmosphere and given a tax incentive, it immediately becomes a green, cheap and more desirable fuel. “For those compelling reasons motorists, legislators and car manufacturers must switch to a sustainable alcohol like synthetic methanol.” Set as favorite Bookmark Email This Hits: 1240 Trackback(0) TrackBack URI for this entry Comments (0) Subscribe to this comment's feed Show/Hide comments Write comment Show/Hide comment form This content has been locked.
