Regenerative

Where there's relative movement, there's a chance to generate electricity, and vehicle wheels move up and down on their suspension the entire time they're in motion. We first encountered regenerative suspension 15 years ago – so how's it going?

Tevva has been working to ease the burden of carbon reductions on fleet operators. In January, it began production of its battery-powered medium-duty electric truck. Now it's improved the efficiency of its regenerative braking system by four times.

EasyJet has announced plans to test a hybrid hydrogen fuel system. The concept was conceived by students at Cranfield University and could save around 50,000 tonnes (55,115 tons) of fuel a year, as well as the associated CO2 emissions. It would recover energy from braking when a plane lands.​
