Electromobility important for GHG reductions
November 24, 2015 § Leave a comment
Electric mobility (not just cars) could contribute far more than previously thought to the reduction of GHG emissions, according to a new paper from Karlsruhe Institute of Technology/Mercator Research Institute of Global Commons and Climate Change. The transport sector (currently accounting for 23% of global energy-related emissions) could nearly halve its emissions by 2050 if a large-scale shift to electric mobility – alongside the promotion of public transport in cities, disincentives to drive, promotion of cycling, etc – is achieved. This would include car-sharing, e-bicycles and electric rail as well as cars, says the paper’s lead author Felix Creutzig, noting: “Efficiency gains will be very difficult to achieve with the conventional automobile fleet from 2025 on. A fuel shift will be the only remaining option to advance decarbonisation.” KIT’s Patrick Jochem adds: “Electrification of cars may also contribute to the energy turnaround, provided that electric vehicles are integrated smartly into the energy system. Shifting of charge processes to strong-wind hours might relieve the energy system and, hence, create synergies between both sectors.” More here; full paper – in Science, Vol. 350, no. 6363, pp.911-912, here.
- On that note, the launch yesterday of the 100% London campaign -100% clean energy by 2050, also aimed-for by 50-odd Labour-run councils across the country – involves some hearty targets for GHG reductions. Implications for transport policy, of course, and talk about biogas and fuel cell vehicles as well as EVs.
- And the clever folks at KIT are also working on ‘powercaps’ or ‘hybrid capacitors’ – devices combining the properties of batteries and capacitors for energy storage, storing twice as much power as capacitors but able to supply up to ten times more power than a battery. Science bit here.
- Renault has been testing smart-charging management in German with TMH (The Mobility House), which has developed tech to automate EV charging at times of lower-cost electricity. Eleven Zoe-owning Renault employees in Germany have tested the system at their homes and research is ongoing between Renault and TMH on smart-grid communications to smooth out demand peaks and troughs, as well as optimising costs (and charging times) for EV owners. Payments for feeding electricity back to the grid (from cars) are also being studied. TMH has further ongoing collaborations with Daimler (energy storage and second-life batteries) and with Volkswagen (supply of home-charging solutions).
- Volvo’s Concept 26 – revealed at the Los Angeles Auto Show last week – is another vision of the future of commuting. It’s a take on the autonomous theme with a three-way seat which adapts to Drive, Create and Relax modes, involving degrees of seat recline, retraction of the steering wheel and a fold-out display screen – to either make use of the commute time “creatively” or to sit back and relax, watch media or listen to music. Volvo’s Drive Me research project is to get fully-autonomous vehicles on the road, “driving real customers” in Gothenburg next year. And the ’26’, apparently, refers to the average US commuting time. (On a related note, interiors supplier Faurecia is working on a research project with a team from Stanford University to study the issue of motion sickness in self-driving cars…)
- Speaking of Gothenburg, I’m liking the Stadsleveransen – a city delivery service combining an electric vehicle-pulled ‘train’ of goods trailers and six-wheeled cargo bikes, driven by the ‘pooling’ and aggregation of deliveries to shops and businesses in a central area. Has cut down on traffic and parked vehicles, enabled increasing pedestrianisation and cycling, and created an all-round more pleasant place, they say.
