Retired Nissan Leaf batteries are ending up somewhere weird
Nissan is partnering with Aeroporti di Roma's Fiumicino Airport, Italy's largest transport hub, to give retired Nissan Leaf batteries a new purpose in life. The batteries will form part of the airport's new battery energy storage system in an ambitious net zero project to provide clean, reliable power to terminals by 2030.
Nissan's reconditioned Leaf batteries will provide 2.1MWh of capacity to the 10MWh battery system. Coupled with 55,000 solar panels, the setup is due to generate 31GWh of electricity to the airport every year.
As well as helping to keep the departure boards lit, Nissan says the initiative demonstrates the potential for 'end of life' EV technology to be recycled in innovative new ways. Recycling electric vehicle batteries is notoriously difficult, and driven mostly by the demand for the rare metals – like lithium, nickel and cobalt – that go into their construction.
Nissan supplied a total of 84 used 30kWh and 40kWh batteries to the airport's battery energy storage system, sourced from high-mileage Leaf EVs and warranty returns. Each battery has been refurbished and requalified to ensure their safety and performance, and Nissan predicts they'll be operational for 6-7 years with daily use.
Soufiane El Khomri, energy director at Nissan, says, 'This project not only demonstrates the long-term viability of repurposed EV batteries in demanding environments, but underscores Nissan's commitment to sustainable end-of-life battery management.
'Our team is involved in the technical integration of second-life batteries into the [energy storage system], the simulation of battery lifespan, and providing warranties for their performance in the new system. Just as importantly, once the batteries reach the end of their useful life on this project, we take full responsibility for their recycling.'
This isn't the first collaboration between Nissan and European energy providers. A similar battery storage project is already in operation in Melilla, Spain, where electric vehicle batteries are used as a critical backup for a power plant.
'We are turning potential waste into valuable energy assets,' El Khomri added. 'Our re-use strategy not only supports large-scale industrial projects such as Aeorporti di Roma's Fiumicino Airport, but also shows potential for use in the home such as backup during power cuts.'
'As we continue to scale battery reuse and recycling, we are advancing our broader mission toward a cleaner, more energy-efficient future.'

China rushes to build out solar, and emissions edge downward
High on the Tibetan plateau, Chinese government officials last month showed off what they say will be the world's largest solar farm when completed — 610 square kilometers (235 square miles), the size of the American city of Chicago. China has been installing solar panels at a blistering pace, far faster than anywhere else in the world, and the investment is starting to pay off. A study released Thursday found that the country's carbon emissions edged down 1% in the first six months of the year compared to a year earlier, extending a trend that began in March 2024. The good news is China's carbon emissions may have peaked well ahead of a government target of doing so before 2030. But China, the world's biggest emitter of greenhouse gases, will need to bring them down much more sharply to play its part in slowing global climate change. For China to reach its declared goal of carbon neutrality by 2060, emissions would need to fall 3% on average over the next 35 years, said Lauri Myllyvirta, the Finland-based author of the study and lead analyst at the Centre for Research on Energy and Clean Air. 'China needs to get to that 3% territory as soon as possible,' he said. China's emissions have fallen even as it uses more electricity China's emissions have fallen before during economic slowdowns. What's different this time is electricity demand is growing — up 3.7% in the first half of this year — but the increase in power from solar, wind and nuclear has easily outpaced that, according to Myllyvirta, who analyzes the most recent data in a study published on the U.K.-based Carbon Brief website. 'We're talking really for the first time about a structural declining trend in China's emissions,' he said. China installed 212 gigawatts of solar capacity in the first six months of the year, more than America's entire capacity of 178 gigawatts as of the end of 2024, the study said. Electricity from solar has overtaken hydropower in China and is poised to surpass wind this year to become the country's largest source of clean energy. Some 51 gigawatts of wind power was added from January to June. Li Shuo, the director of the China Climate Hub at the Asia Society Policy Institute in Washington, described the plateauing of China's carbon emissions as a turning point in the effort to combat climate change. 'This is a moment of global significance, offering a rare glimmer of hope in an otherwise bleak climate landscape,' he wrote in an email response. It also shows that a country can cut emissions while still growing economically, he said. But Li cautioned that China's heavy reliance on coal remains a serious threat to progress on climate and said the economy needs to shift to less resource-intensive sectors. 'There's still a long road ahead,' he said. One solar farm can power 5 million households A seemingly endless expanse of solar panels stretches toward the horizon on the Tibetan plateau. White two-story buildings rise above them at regular intervals. Sheep graze on the scrubby vegetation that grows under them. Solar panels have been installed on about two-thirds of the land. When completed, it will have more than 7 million panels and be capable of generating enough power for 5 million households. Like many of China's solar and wind farms, it was built in the relatively sparsely populated west. A major challenge is getting electricity to the population centers and factories in China's east. 'The distribution of green energy resources is perfectly misaligned with the current industrial distribution of our country,' Zhang Jinming, the vice governor of Qinghai province, told journalists on a government-organized tour. Part of the solution is building transmission lines traversing the country. One connects Qinghai to Henan province. Two more are planned, including one to Guangdong province in the southeast, almost at the opposite corner of the country. Making full use of the power is hindered by the relatively inflexible way that China's electricity grid is managed, tailored to the steady output of coal plants rather than more variable and less predictable wind and solar, Myllyvirta said. 'This is an issue that the policymakers have recognized and are trying to manage, but it does require big changes to the way coal-fired power plants operate and big changes to the way the transmission network operates,' he said. 'So it's no small task.' ___ Moritsugu reported from Beijing.

Plans for solar farm set to take step forward in Leicestershire
Plans for a solar farm on the Leicestershire and Rutland border that could provide power for about 25,000 homes are set to take a step forward. Melton Borough Council's planning committee has been recommended by officials to approve proposals for a solar farm measuring 87 hectares (215 acres) on land at Stygate Lane between Pickwell, Somerby and Whissendine.A council report stated plans had also been submitted to Rutland County Council and the part of the development in Melton would not go forward unless both authorities granted planning report added the proposals would enable Melton to make a "significant contribution" to the decarbonisation of the national power supply. Documents submitted by the applicant said the proposed development would meet the electricity demand of up to 25,175 homes and would save about 43,393 tonnes of carbon each to Melton Borough Council, plans for the proposed development are due to be discussed on 28 August while the application remains under consideration by Rutland County Council.
