The EC is working on a carbon tax on car drivers as part of its big climate plan review in June. William Todts at T&E warns that the EC shouldn’t make the same mistake French President Macron made back in 2018 when severe gilets jaunes protests against a fuel price hike made him back down. A very high carbon price, caused by letting the market decide the price, may have the same effect, getting us nowhere. Instead, Todts gives his three point … [Read more...]
Only giving tax breaks to zero-emission company cars will accelerate e-mobility
Subsidies and tax breaks for company cars in Europe cost €32bn a year, a hangover from the days when governments were happy to encourage driving. Chris Bowers at T&E reviews a study that explores the issue in a wide range of European nations and reveals that 96% of company cars are petrol and diesel. As an indicator of the scale of emissions, the study says Europe’s 10 largest leasing companies alone – which include BMW’s Alphabet and … [Read more...]
Latest data shows lifetime emissions of EVs lower than petrol, diesel
Critics of the rapid roll out of electric vehicles correctly say that their factory door emissions (i.e. CO2 emitted during manufacture) are higher than those for standard petrol and diesel cars. Then you have to add the emissions of the local grid (how renewable is it?!) that’s charging your EV. But the numbers behind those calculations are always changing. Eoin Bannon at Transport and Environment describes the findings of their new tool that … [Read more...]
Are national fossil fuel car bans compatible with EU laws, intra-trade, movement?
A growing number of EU nations are announcing laws to phase out the sale of new fossil fuel cars within the next 20 years. But are the proposed bans compatible with EU laws, or even workable given cross border trade and movement rights? If you are Dutch, why not buy your new petrol car in Belgium, then drive it back to the Netherlands? How do you enforce CO2 targets with foreign haulage fleets transiting through your nation? Eoin Bannon at … [Read more...]
UK rail: where are the electric-diesel hybrids, hydrogen, battery trains?
Cars and planes get much more attention than trains when it comes to emissions. That makes sense when, in the UK, transport accounts for 26% of all carbon emissions but only 1% of this comes from trains. Also, trains are already relatively emission-low: they release 0.046kg of CO₂/km/passenger while a diesel car is more than double that. Marcus Mayers and David Bamford at Manchester Metropolitan University explain that the crucial difference is … [Read more...]
Hydrogen Fuel Cell trucks can decarbonise heavy transport
Patrick Molloy at Rocky Mountain Institute runs through the pros and cons of hydrogen fuel cell vehicles (FCEVs). The big pluses are that hydrogen has an energy density of around 120 MJ/kg, almost three times more than diesel or gasoline. Half the energy generated by an internal combustion engine is wasted as heat, whereas electric drivetrains used by FCEVs only lose 10%. Nikola Motors, a U.S. maker of hydrogen trucks, claims its vehicles can get … [Read more...]
Extract CO2 from our air, use it to create synthetic fuels
Carbon Capture needs to take off, but nobody knows how it’s going to happen. We need innovation, scrutinised, tested and funded. Jim Conca looks at a method of extracting CO2 directly from the air that’s being pioneered by Carbon Engineering in Canada, backed by private investors and government agencies. It grew out of academic work at the University of Calgary and Carnegie Mellon University. It’s “Direct Air Capture” system can remove a ton of … [Read more...]
Can India’s 30m grid/diesel irrigation pumps go solar?
The Indian government is looking for effective ways to increase the use of solar powered pumps for small farm irrigation. About 70% of India’s rural households still depend primarily on agriculture for their livelihood, and successful farming usually requires irrigation. Currently, 21m pumps are connected to a primarily fossil fuel grid and 8.8m are diesel while solar has risen to just 130,000, mostly added in the last 5 years. Lelin Thouthang … [Read more...]
U.S. Military’s mobile mini-nuclear: fewer fuel supply convoys mean fewer casualties
U.S. Military figures show the resupply of liquid fuel and drinking water for troops in-theatre costs about 4 lives for every 100 convoys. It makes an army more vulnerable and limits movement. That’s why the U.S. Department of Defense is looking at very small modular nuclear reactors (vSMRs): sub-10MW nuclear units. They are already being designed, built and tested. If successful, no refuelling is required for years and the units can be … [Read more...]
New Car sales data shows EVs still a luxury as Petrols keep rising
It’s hard to argue that the EV revolution is around the corner when petrol car sales keep rising. Yes, diesel sales are falling, but more people are switching to petrol than EVs. This month, two data releases from the European Automobile Manufacturers' Association (ACEA) show that EV’s big gains are only happening in the high income countries. Even wealthy Norway’s 49.1% EV market share is an exception. The nations that come second and third are … [Read more...]
Onsite solar and storage powers off-grid telecom towers
There are more than 3m telecom towers globally, and powering them is a $100bn market. It's a particularly important growth sector in developing countries. They are already using mobiles to leapfrog the laying of costly landlines, but because they lack grids that stretch to remote communities they need to power towers that are off the grid. Dr Thomas Hillig says as solar and storage costs continue to drop they are replacing diesel gensets as the … [Read more...]
