Replacing fleets of medium- and heavy-duty trucks can help cut greenhouse gas emissions and make cities quieter and cleaner. Because trucks need so much hauling power, they have eluded electrification until recently; a battery that could pull significant weight would itself be too hefty and too expensive. But now, improvements in battery technology are paying off, bringing down both size and cost. The number of hybrid-electric and electric trucks is set to grow almost 25 percent annually, from 1 percent of the market in 2017 to 7 percent in 2027, a jump from about 40,000 electric trucks worldwide this year to 371,000.
All major delivery companies are starting to replace their gas-powered fleets with electric or low-emission vehicles, a switch that companies say will boost their bottom lines, while also fighting climate change and urban pollution. UPS has placed an order for 10,000 electric delivery vehicles. Amazon is buying 100,000 from the start-up Rivian. DHL says zero-emission vehicles make up a fifth of its fleet, with more to come. And FedEx just pledged to replace 100% of its pickup and delivery fleet with battery-powered vehicles.
Lithium-ion battery prices fell by 19% every time global cumulative production doubled.
Beyond grid stabilisation benefits, smart charging of EVs, using differentiated electricity tariffs in off-peak hours, may also mitigate the pressure on electricity demand. That's because vehicles can be charged during the day, when demand is lower and renewables generation is available.
Intermittency from solar or wind technologies can put creating voltage and frequency variations. Batteries can charge and discharge to stabilise the grid in such instances. The batteries of electric vehicles, e-buses or electric two-wheelers, while connected to the grid, could therefore play a role in protecting a grid's stability.
Electric vehicles, delivery drones and rules on when delivery trucks can operate are some solutions proposed in a new report. The report provides 24 recommendations for policymakers and the private sector, including mandating that delivery vehicles are electric. The report notes that if policymakers care about sustainability, they may want to impose aggressive new electric vehicle regulations.
While electric vessels offer zero emissions and lower operational costs, the upfront cost is significantly higher than conventional fuel-driven ships because of pricey batteries and electric propulsion systems. The technology is already available, so it's about bringing down costs and producing on a scale to create a competitive industry.
