‘Hybrids are way forward’ claims emissions specialist

The most effective way to reduce global vehicle emissions is mass adoption of hybrid vehicles, says Emissions Analytics, specialist consultants in emissions and fuel efficiency.

With consumer adoption of battery electric vehicles (BEVs) hesitant and slow infrastructure roll-out compounded by concerns around an economical supply of batteries, the company says it is essential to find the fastest, most efficient way to reduce CO2 now.

“One of our biggest challenges is fleet turnover, with vehicles staying on the road typically for up to 12 years,” explained Nick Molden, CEO of Emissions Analytics.

“It means that refreshing the entire fleet is a very slow process. Given reservations about current BEVs, we require an alternative that will have a more immediate impact. Due to CO2’s long life in the atmosphere, a small change now is far better than a large change in the future. We need to optimise the use of the industry’s available battery capacity to facilitate a critical early reduction.”

Through ‘real-world’ testing of electrified vehicles, Emissions Analytics says it has found that hybrids, whether in petrol or diesel form, offer the highest CO2 reduction per kWh across all electrified powertrains.

“The ideal solution is an immediate transition to petrol and diesel hybrids, with a further decade spent refining the technology, infrastructure and battery supply chain to allow the adoption of BEVs,” said Nick Molden. “By 2030, the EU and the US would have had another decade to develop expanded, cleaner electricity generation capacity, improving the lifecycle emissions of BEVs.

“Alternatively, by 2030 the availability and price of renewable energy may well fall to a level at which hydrogen fuel cells could be economically viable. These avoid the environmental and geopolitical issues caused by large-scale battery production and would likely offer even lower lifecycle emissions.

“The overall message is this though: it is paramount that governments and industry take into consideration real-world data when promoting technologies to efficiently reduce CO2.”
