How to cope with the hourly, daily and seasonal variation in demand as regions electrify more, depend more on variable renewables like wind and solar, and cut baseload fossil generation? Storage shifts load nicely. But why build grid-scale batteries when millions of little batteries in our EVs are sitting idle in our driveways for most of the time? As Mark Specht at the Union of Concerned Scientists explains, it’s why in California a bill is … [Read more...]
IRENA’s Innovation Week 2023: Renewable solutions to decarbonise end-use sectors
At the end of September IRENA held a four-day event “Innovation Week 2023: Renewable solutions to decarbonise end-use sectors” in Bonn, Germany. A wide range of speakers discussed tangible solutions to decarbonise energy intensive sectors such as transportation, buildings and industry, informed by first-hand project experiences and supported by insights from IRENA’s in-depth analyses. Topics included direct and indirect electrification, green … [Read more...]
Formula 1’s energy efficiency innovations for road transport are being wasted
Formula 1 racing is infamously emissions intensive. But the pressure to win is a pressure to innovate and raise energy efficiency, supported by an extravagant budget. Maximilian Auffhammer at the Energy Institute at Haas looks at what has been achieved over decades, and what has – and has sadly not – been translated onto our roads. The earliest cars had 4.5L engines that produced 400 horsepower, refuelled during the race. Today’s cars have 1.6L … [Read more...]
Concrete supercapacitor: works like a battery, much cheaper, easy to make
Capacitors work like batteries. They store and discharge electricity. David Chandler at MIT explains how researchers there have designed a supercapacitor from concrete and carbon black, two cheap and common materials. The beauty of the idea is that they can be incorporated into building foundations, thus installing a battery virtually for free. A concrete capacitor cube 3.5m wide can store 10kwh, enough for a household. Similarly, concrete … [Read more...]
Affordable €25k EVs by 2025: Europe’s carmakers can do it. Instead they’re making more profitable SUVs
T&E present a summary of their study which shows that European carmakers can produce affordable EVs (40 kWh LFP battery, 250-300 km range) priced at €25k by 2025 with a reasonable 4% profit margin. Priced for the mass market, this would add a million extra EV sales annually, accelerate the removal of combustion engines, and counter China’s dominance of the EV market. The obstacle is the insistence by Europe’s leading manufacturers - BMW, … [Read more...]
Europe’s grid bottlenecks are delaying its energy transition
***While you're here... REGISTER NOW for "REPowering the grid for Solar PV" with the Vice-President of Tauron, DG ENER C, Eurelectric and SolarPowerEurope - Online Wednesday September 20 from 11:00 to 12:15 CEST*** No amount of record sales and deployment in Europe of heat pumps, EVs, solar farms, wind turbines and all the rest will guarantee the region meeting its electrification targets if the grids aren’t ready to integrate them. As … [Read more...]
Draft EU rules on Battery lifecycle decarbonisation: close the loopholes!
Draft rules mean battery manufacturers selling into Europe will have to report the product’s entire carbon footprint, from mining to production to recycling, as early as July 2024. That data will then be used to set a maximum CO2 limit for batteries to apply from the end of 2027. This is a big step forward, says T&E, addressing concerns over battery carbon footprint and recycling, and it also covers environment and human rights. But T&E … [Read more...]
“Battery Passports”: ensuring environmental sustainability, decarbonisation and mining labour rights
With battery production taking off, concerns are focussed on environmental sustainability, carbon footprint and labour rights where the raw materials are mined. Benedikt Sobotka, Co-Chair at the Global Battery Alliance and Robin Zeng, CEO at Chinese manufacturer Contemporary Amperex Technology, writing for WEF, describe the concept of the digital “battery passport” where compliance with the rules is certified and monitored throughout the life … [Read more...]
France plans the social leasing of EVs at €100/month. Can it jump start affordable electric cars?
Social leasing of EVs could become the breakthrough example of climate action done right, explains William Todts at T&E. And France’s president Macron has promised to do it, aimed at low-income households to counter criticism that even with subsidies EVs are still out of reach for many. Todts quotes T&E analysis that shows that between 2024 and 2030 around 900,000 low-income households could benefit from monthly leasing costs of €70 to … [Read more...]
EU’s 40% domestic Cleantech ambition: same target for Wind (easy) and Solar (hard) doesn’t make sense
The proposed Net Zero Industry Act includes a target for the EU to manufacture domestically at least 40% of its cleantech deployment needs by 2030. That includes the key technologies of solar PV panels, wind turbines (onshore and offshore), EV batteries, heat pumps and hydrogen electrolysers. But it doesn’t make sense to have the same 40% target for all, explain Giovanni Sgaravatti, Simone Tagliapietra and Cecilia Trasi at Bruegel. The main … [Read more...]
Community Batteries: when they’re the best option for overcoming grid constraints. And when they’re not
Community batteries are a shared asset in neighbourhoods with rooftop solar, avoiding the need for every household to have its own battery. Even people unable to have rooftop solar can use it. It’s taking off in Australia, supported at both the state and federal level. But Bjorn Sturmberg, Alice Wendy Russell, Hedda Ransan-Cooper, Louise Bardwell and Marnie Shaw at the Australian National University summarise their research which warns that it … [Read more...]
Five charts on the Energy Transition: the 2020s is the decade of maximum disruption. By 2030 the endgame will be clear
Sam Butler-Sloss and Kingsmill Bond at RMI present a succinct summary of why the energy transition matters, how the 2020s is the era of maximum disruption, and how by 2030 the transition’s endgame will be apparent (though far from complete). Four key technologies are already entering the exponential growth stage: solar, wind, EVs and heat pumps. As early as 2030 their cheapness will flush away the fossil equivalents in succeeding decades, say the … [Read more...]
Global “explosive” growth means 1 in 3 new cars will be electric by 2030. But SUV emissions could wipe out those gains
More than a third of all new vehicles sold globally in 2030 will be electric, according to the IEA. That’s a doubling of its prediction made only two years ago. Josh Gabbatiss at Carbon Brief summarises the report. The IEA describes the growth as “explosive”: from just 1% of global car sales in 2017, to 14% last year, and now 18% expected by the end of 2023. China has consistently dominated those sales while new policies in the U.S. and EU are … [Read more...]
How can Europe stop U.S. and China dominance of cars and batteries without being protectionist?
European and Chinese car and battery makers are making plans to set up plants in the U.S. to take advantage of their big new “made in the USA” subsidies. They can then ship their vehicles to Europe to sell into its very large and generously subsidised company car market. This puts electric vehicle production in Europe at a serious disadvantage. As William Todts at T&E explains, the EU must respond, instead of effectively assisting the U.S. … [Read more...]
Can Phytomining deliver Critical Minerals at scale: farming plants that accumulate high metal concentrations
Both Europe and the U.S. are making plans to secure supplies of critical minerals as the transition gains pace. Domestic mining or securing import deals with close allies is the main focus. Here, Maria Krol-Sinclair and Thomas Hale at CSIS review the prospects for a new method that will require neither: phytomining. Some plants, called hyperaccumulators, soak up high concentrations of metals into their leaves, bark, and roots. These plants can … [Read more...]
