Since the 1970s, fuel-economy improvements in U.S. “light-duty” vehicles, with a contribution from rising gasoline prices, have saved 17bn tonnes of CO2, according to a new study reviewed by Josh Gabbatiss at Carbon Brief. That makes rising fuel efficiency’s impact on emissions reductions second only to that of coal-to-gas. New cars, vans and light trucks get about twice as many miles to the gallon as 1975 models. The amount of gasoline therefore … [Read more...]
Wireless recharging of EVs as they drive?
Engineers have demonstrated a practical way to use magnetism to transmit electricity wirelessly to recharge electric cars. Stationary wireless EV charging has already been piloted and promoted by companies like Connected Kerb in the UK and car manufacturers. Experiments with the mobile version have also been conducted. Clearly, the less often an EV has to stop to recharge the better. But this has run into the problems of energy conversion … [Read more...]
Re-shaping the EU ETS as a safety net, not a driver
The EU ETS (Emissions Trading System) has struggled to cope with the current economic crisis which has caused a drop in the European carbon price, while the expected drastic drop in 2020 emissions will only add to the existing surplus of allowances. This highlights how necessary it is to reform the mechanism for managing this surplus or even to implement a carbon floor price, explain Charlotte Vailles at I4CE and Nicolas Berghmans at IDDRI. They … [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...]
An EU Hydrogen strategy: from industry feedstock to energy vector
The bravest recovery strategies will invest robustly in new yet-to-take-off clean energy technologies. If you are going to have to spend hundreds of billions to revive your economy isn’t it better to replace the old with the new rather than prop up what you’ll have to abandon soon anyway? In anticipation of that happening, new technologies are lining up. Here, Cédric Philibert at the IFRI Centre for Energy & Climate summarises their detailed … [Read more...]
IRENA’s Global Renewables Outlook and how Europe can lead the way
If the coronavirus slump has knocked everything off track IRENA’s first ever Global Renewables Outlook is a timely reminder of what that track should look like. It can help policymakers design stimuli packages that will get us back onto it, and even accelerate the transition. IRENA’s Gayathri Prakash, Nicholas Wagner and Ricardo Gorini run through the comprehensive report’s main recommendations. Annual investment, shares and GW targets to 2030 … [Read more...]
Green Ammonia can replace fossil fuel storage at scale
What’s the best way to store energy, from industry scale to electric vehicles, replacing the widespread use of fossil fuels? Pure hydrogen is an energy dense alternative, but the gas takes up a lot of space. Liquid ammonia doesn’t, yet it contains the hydrogen and therefore the energy. Ian Wilkinson at Siemens explains the advantages of using ammonia, NH3. Already the world produces 180m tonnes a year, worth €80bn. It’s mainly for agricultural … [Read more...]
Accelerate EV infra, buildings refits to use electricity’s looming spare capacity
How do we turn the pandemic downturn into an executable opportunity, above and beyond targets and promises? Chris Nelder at RMI presents data on how electricity load has dropped during the lockdown in the U.S. That load will return when the economy recovers. In the interim capacity will go unused. New capacity in the pipeline could be delayed. Nelder suggests policy makers grasp the opportunity to fill that gap and use that capacity by directing … [Read more...]
Behaviour Change: Covid-19 lockdown kicks open the door to a net-zero pathway
Working from home and minimal travel are “no brainer” ways to drastically reduce emissions. They’ve never been tried on a nationwide scale anywhere. Now they are, everywhere. Everyone is doing their best to make it work. Next, food waste should also be in decline, hopefully. Even if panic stockpiling happens, people’s mindsets are being changed as they try to use everything they’ve bought. The act of re-thinking what and how much we eat, in every … [Read more...]
Covid-19 and the EU car industry: any support should lock in EV targets
The coronavirus slump has come suddenly and hit hard. The deep thinking has already begun on the economics needed to turn around that slump without damaging our rising emissions ambitions. Julia Poliscanova at Transport & Environment looks at the car industry. Some have called for the new CO2 standards coming in 2020 to be postponed (though, notably, VW and BMW still support them). She explains that total car sales were already declining in … [Read more...]
Europe needs its own EV battery recycling industry
Europe needs its own battery recycling industry, and the EU’s European Battery Alliance should make it happen, says Raphaël Danino-Perraud writing for the IFRI Centre for Energy & Climate. For economic, strategic and environmental reasons, today’s overwhelming dependence on outsourcing – in this case to Asia - for battery manufacture and recycling needs to change. To start with, Asia provides over 90% of global car battery output, half coming … [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...]
“All new vehicles sold must be electric by 2030” but can your nation, state, city do it?
More and more nations, states and cities are announcing plans for the ramping up of EV adoption. Jim Conca takes a look at his home, Washington State in the U.S., where all new vehicles sold must be electric by 2030. He says the new rules imply his state will have 4 million EVs on the road by 2045, up from 52,000 today. He carefully crunches the numbers to see if this target is realistic. The good news is that grid capacity will only need to rise … [Read more...]
UK’s COP26 Presidency will be the first big test of its post-Brexit diplomatic skills
November’s COP26 will arguably be the most important since the Paris Climate Agreement of 2015. By then, all signatory nations are required to submit their new and improved nationally determined contributions (NDCs) that set a credible pathway towards reducing their emissions. So far only the Marshall Islands, Suriname, and Norway have done so. Lucien Chabason and Lola Vallejo at IDDRI ask whether the UK teams behind their new COP26 President, … [Read more...]
Machine learning cuts new EV battery design testing times by months, years
Normally, battery prototype testing can take months and years to find the optimal design for fast-charging and battery life. Now scientists from Stanford, MIT and the Toyota Research Institute have developed a machine learning programme that can cut battery testing times by 98%. They’ve applied it to EV batteries. The faster a new and improved design is proven and taken to market the more rapid the uptake of EVs we’ll have. Matthew Vollrath at … [Read more...]
