Transport for London (TfL) and FM Conway (FMC) have partnered with Volvo CE and SMT on a pioneering new trial of zero-emission construction vehicles, with an electric excavator and wheel loader replacing equipment traditionally powered by fossil fuels, a first for TfL. The project’s goal is to improve pedestrian safety at Redcliffe Gardens by creating raised sections of road that slow traffic and make crossings safer for pedestrians.
New advances in technology such as those being trialled at the site could play a vital role in reaching the Mayor of London’s target for London to be net zero carbon by 2030.
“The health of everybody in London is central to our work, and we are determined to meet our 2030 net zero targets. That’s why I’m so pleased that we’re continuing to take these important steps to reduce emissions and protect air quality.”
said Carl Eddleston, TfL’s Director of Network Management and Resilience.
The works on three junctions at Redcliffe Gardens, over a longer 11-week period, will improve pedestrian safety by creating raised sections of road that slow traffic and make crossings safer for pedestrians, to complement reduced road speed limits. It will also improve bus stop accessibility by extending the pavement. TfL is committed to the Mayor’s Vision Zero goal to eliminate death and serious injury from the capital’s transport network by 2041.
The electric vehicles use a UK-first method of recharging provided by Charge Fairy, a British electric charging startup. They can provide real-time updates on the machines’ charging levels when on-site, which feeds into a team who then sends a charging van to the site. This method of bringing the charger to the vehicle allows the construction machines to be recharged in an hour. Developments in how vehicles on construction sites are powered and charged could revolutionize how the capital’s transport network is built, ensuring London is greener and healthier for all.
“We’ve long advocated that bringing energy to electric vehicles can make more sense than taking the vehicle to a charger—nowhere is this more true than with construction equipment. Our work at Redcliffe Gardens has demonstrated how intelligent energy delivery enables electric plant to operate for a full workday, overcoming one of the key challenges of construction electrification.”
said Ed Lea, Founder of Charge Fairy.
Diesel construction excavators are responsible for emissions equivalent to more than 100,000 passenger cars. If these vehicles were to be replaced with zero-emissions alternatives, they could play an important role in making the capital cleaner and greener. Early data from the trial confirms that in a two-week period, the electric excavator saved more than 100kg of CO2, equivalent to driving a car 600 kilometers. Additional harmful pollutants were eliminated (e.g. NOx, particulate matter, non-methane hydrocarbons and carbon monoxide) when compared with a diesel excavator completing the same work.
The use of zero-emission electric vehicles demonstrates TfL’s commitment to reaching the Mayor of London’s target for London to be net zero carbon by 2030. The works specifically aim to reduce the environmental impact of construction, with the reusing of materials and the recycling of almost all concrete waste by FMC. Additional waste is taken and reused in future TfL projects to ensure minimal environmental impact.
“FM Conway is always looking for ways to support Transport for London in reaching their net zero ambitions, and a strong supply chain filled with companies willing to innovate has been key in the delivery of this trial. This bespoke charging solution removes many of the barriers we have faced in the use of electric plant machinery, and we’ve seen from the works on Redcliffe Gardens that it represents a viable option for similar sites in the future.”
said Matt Tallon, Sustainability Director at FM Conway.
