The Danish chemicals expert thinks its enzymes could help break down barriers to sustainable biofuels. The fast-rising uptake of electric cars around the world means there could be 125 million on the road by 2030, up from just three million in 2017. But despite the growing success story of electric cars, the fact remains that the share of renewable energy in transport sat at only 2.8 per cent globally in 2015. Even under progressive projections, just one third of the world’s cars will be electric or hybrid by 2040. Meanwhile, other transport sectors such as heavy duty vehicles, aviation and shipping are proving more challenging to electrify.
