What happened when Sweden introduced a 25% rebate on the cost of an e-bike for 12 months over 2017-18? Lucas Davis at the Haas School of Business reviews a study that digs into the consequences. Sales increased by 70%. E-bike prices remained steady, so the sellers didn’t simply raise prices to eat up the rebate. The study estimates that although a third of those sales would have “happened anyway” (i.e. no additionality) the remaining two-thirds … [Read more...]
If most truck journeys are less than 300 miles the E-Truck revolution can happen now
What proportion of trucks today could go electric? That’s the question Emily Porter at RMI has asked for California and New York. The answer is 65% of medium-duty trucks and 49% of heavy-duty trucks. Those are very encouragingly high numbers. RMI’s definition of “electrifiable” is if they travel fewer than 300 miles between trips to their home bases. The study gathered real data on how freight trucks are driven today. Clearly, a large number of … [Read more...]
New research ranks the 12 best ways to cut car use in cities
Behaviour change is as an important part of our transition journey as the clean energy revolution. Kimberly Nicholas at Lund University summarises research that has gathered together nearly 800 peer-reviewed reports and case studies from across Europe that analyse ways of reducing car use. One main challenge is to quantify the benefits so policy-makers and citizens can make evidence-based decisions on how to re-imagine city mobility. Nicholas … [Read more...]
Aviation policy alert: non-CO2 emissions have up to four times the climate impact
There’s little point designing CO2 policies without knowing what other factors are heating up the atmosphere. So it is with aviation. The non-CO2 emissions (aromatics, NOx, SO2, H2O, particulate matter, etc.) from jet engines have up to four times the effect of CO2. You can see it in the contrail cirrus streaks trailing behind aircraft. Carlos LĂłpez de la Osa at Transport & Environment summarises their recent summit that brought together … [Read more...]
Piloting green shipping corridors: Australia-Japan and Asia-Europe
The shipping industry is diverse, disaggregated and part of the logistical chain of 80% of global trade. So reducing its emissions (3% of the global total) will be complex. One way to cut through this complexity is to create a limited number of green shipping corridors between major port hubs, to pilot solutions. This can shrink the challenge of coordination between fuel infrastructure, vessels, firms and national policies down to a manageable … [Read more...]
E-fuels for cars are expensive, and pollute the air as much as petrol
MEPs and governments are currently deciding on an EC proposal for all new cars sold from 2035 to be 100% zero-emissions. Here, T&E present test results that show e-fuels should not be allowed to replace petrol. T&E are concerned that e-fuels are being promoted as a way to prolong the life of ICE vehicles. But their tests show that e-fuels produce just as much NOx, three times more carbon monoxide, and twice as much ammonia. Though e-fuels … [Read more...]
The 10 big problems with simply replacing fossil cars with electric
The planned rapid transition to electric vehicles has major challenges. Schalk Cloete compiles them into a list of ten, including: preserving our car-centric cities preserves its inefficiencies and societal costs; it works against much of the personal “behaviour change” we need; though BEVs (battery electric vehicles) are better in cities, when infrastructure costs are included they are less efficient than hybrids and modern ICEs for many driving … [Read more...]
Vehicle charge zones: too high, and driver detours can increase emissions
Vehicle congestion charge zones are a way of taxing drivers for the emissions they create. They have great potential to steer polluters towards shorter and/or fewer journeys, and towards cleaner fuels. But it's full potential that has gone mostly untapped. Most “cordon zones” found in big cities like London, Stockholm, Milan and Singapore keep the rules very simple. Journey length is rarely, if ever, taken into account. Importantly, no one is … [Read more...]
Concern over auto job losses as Europe transitions to EVs
The state premier of Lower Saxony, home of Volkswagen, says he would not tolerate a large-scale reduction in staff at Germany’s largest carmaker. There is talk of axing 30,000 VW jobs nationwide, though messages have been mixed. Benjamin Wehrmann and Sören Amelang at Clean Energy Wire look at the latest news, then summarise the implications of the EV transition for the auto industry across Europe. Highlights include the observation that a Tesla … [Read more...]
Green hydrogen-based fuels pivotal in decarbonising Shipping by 2050
The international shipping sector’s emission levels are comparable to Germany’s. Like aviation and heavy transport, reaching net-zero will need renewable fuels – direct electrification won’t be sufficient. Existing fossil fuel engines allow for biofuel blends of up to 20% without any modifications, and 100% methanol engines are a proven technology. Making sufficient quantities of clean fuels - without consuming food crops – is the challenge. … [Read more...]
Clean transport in Europe: key trends to watch out for
T&E’s quarterly trends series gives a snapshot of the key developments that will define the future of clean transport in Europe. And what Europe does – given it wants to lead this field – should influence what happens worldwide. T&E’s Thomas Earl brings attention to four issues. First, proven progress in this major sector makes it a contender for a significant role in Europe’s new industrial strategy. It ranges from battery and … [Read more...]
New cooling system for inverters brings electric Heavy-Duty Trucks closer
39% of greenhouse gas emissions in the transport sector comes from heavy-duty trucks. Commercial batteries struggle to deliver enough power to make electrification feasible for heavy-duty applications. Rebecca Martineau at NREL explains how a working prototype, developed with the heavy machinery manufacturer John Deere, is now getting a 378% increase in power density. The key to the innovations rests on a state-of-the-art thermal management … [Read more...]
Giving car manufacturers e-fuel credits will slow the rise of EVs
Transport & Environment (T&E) explains why e-fuel credits should not be included in the EU’s CO2 standards for new cars. If they are, it would give carmakers the option to claim an ICE vehicle as low- or zero-emission. But carmakers have no control over what fuel their customers put in their cars, making the regulation impossible to monitor. That opens the door to double-counting emission reductions with other existing regulations (Fuel … [Read more...]
Can Aluminium-air batteries outperform Li-ion for EVs?
Aluminium-air (Al-air) batteries for cars are an innovative technology that automakers and policy-makers should take a close look at, say Helena Uhde and Veronika Spurná at ECECP. Although a battery, they behave more like an engine: the fuel is the aluminium which reacts with the air via an electrolyte to produce electric power. Al-air has big advantages over a lithium-ion battery, the favoured choice for EVs. It has a travel range similar to … [Read more...]
Electric Micromobility: how to cut emissions, create jobs and transform urban transport
What if e-bikes, electric scooters and electric skateboards were added to walking and cycling in our attempts to reduce emissions through behaviour change? It’s a promising solution for all those people who genuinely want to reduce their emissions but don’t want the extra exercise. Quoting from their report, Jennifer Dungs at EIT InnoEnergy looks at the gains to be made, along with a valuable reduction in city congestion. Micromobility is still … [Read more...]
