Electric buses help boost Norwich air quality levels
A fleet of battery-powered buses is being credited with bringing air quality in a city within legal 2023, monitoring in Norwich showed a peak of 38.5 micrograms of nitrogen dioxide in a cubic metre of air. The legal limit in the UK and the EU is County Council said figures show the city level fell to 16.5 micrograms per cubic metre during eight of the past 11 Plant, cabinet member for transport and infrastructure, said: "After all the hard work put into bringing these buses to Norfolk, it's great to see the impact the switch to electric can have for our environment." Councillor Plant added: " These new electric vehicles produce zero tailpipe emissions, which means a cleaner, greener environment for people to live, work and enjoy. "With the Roundtree Way depot now operating a fully electric fleet, Norfolk really is a leader in sustainable public transport in the East of England."First Bus put their hand in their pocket, they put in several million pounds - more than what the government put in - to make electric work in Norwich."That is really important to understand, it's not just the government paying for this; operators are also part of the answer." Asher Minns, executive director of the Tyndall Centre for Climate Change Research, based at the University of East Anglia, said the figures were encouraging, but he would prefer to see a longer monitoring period to be certain about the reduction in emissions."There is no reason to think that the electric buses are contributing to the improvement in air quality in those city centre bits where the air quality was really poor and where the buses are frequent."Air quality improvement really did start from a pretty low base, definitely linked to diesel buses, not least because these were end-of-life buses that were being sent to Norwich, whereas now we've got state-of-the-art electric buses on quite a lot of the routes."He said Norwich, although famous for being flat, was prone to a phenomenon called thermal inversion."[This] is where air pollution can sit on top of the hill that is Norwich in winter on cold days and on hot days," he added."That isn't pollution from Norwich; we accumulate pollution from the continent and the south east, so there is a bit of geography and topography in there which isn't in the control of certainly for Norwich itself, one of the main contributors that can be influenced is to do with air quality from traffic." The battery bus fleet was purchased with a £14.7m government grant, which Norfolk County Council applied for, and £23m from FirstBus, which operates the Eastern Counties Marlow, managing director of First Bus East of England, said: "These figures are a clear sign that zero-emission transport can play a significant role in creating cleaner, healthier places for people. "We're incredibly proud to see the investment in electric buses and depot infrastructure already delivering meaningful benefits for Norwich."

Norfolk MP seeks assurances over safety of Rushall battery farm
The Green Party co-leader said he wanted to know how fire risks could be managed if plans for one of Europe's largest battery storage sites were want to install more than a thousand battery containers on land on the outskirts of the small village of Rushall, near Diss in the company behind the plan - Elmya - has said safety measures will be in place, residents fear the site could catch Adrian Ramsay – whose Waveney Valley constituency includes Rushall – said he did not "want to scaremonger" but would be meeting with Norfolk's fire chief to discuss their concerns. Battery energy storage systems (BESS) are used to hold electricity generated by renewables like solar and wind farms, which can then be put into the grid when the lithium used in the batteries can cause explosions if it overheats.A fire at a small BESS site in Liverpool in 2020 took fire crews 59 hours to extinguish, whilst a blaze at a huge site in California was left to burn on the advice of fire experts. Ramsay said he would speak to Norfolk's chief fire officer about the proposed site at Rushall, as well as one that would be part of the East Pye solar said he wanted to know how fire risks could be managed and assessed, and how fire crews might access remote, countryside sites:"I don't want to scaremonger on that at all, but I do take the questions residents are raising seriously." Asher Minns, from the Tyndall Centre For Climate Research at the University of East Anglia, said data on BESS sites across the world "wasn't great" but he believed the risk of fire was "very low"."There's better [safety] guidelines coming out all the time," he – which has yet to submit its plans for the site at Rushall – said it would have "advanced monitoring, early fire detection, and suppression systems".Development director James Innes insisted the project's safety was "paramount" and the company would be "following National Fire Chiefs Council guidance".A Norfolk Fire and Rescue spokesperson said: "We continue to proactively work with site designers and operators of battery energy storage systems to help them improve both their site designs, and the accessibility for firefighting. "This is to reduce and mitigate for the likelihood of any fire on their premises." Follow Norfolk news on BBC Sounds, Facebook, Instagram and X.
