Electric vehicles, whether battery- or hydrogen-powered, generate no local emissions. They emit neither CO₂, which is harmful for the climate, nor nitrogen oxides (NO_x), which have been proven to be harmful to human health, or indeed any real noise. And electric vehicles can be a major factor in supporting the energy shift if electricity generated from renewables like wind or solar power is used in batteries or stored in the hydrogen produced by electrolysis.

Electricity powers e-vehicles. This electricity can come either directly from a charger which charges a battery in the car, or from a fuel cell on board, which uses hydrogen to generate electric power and water. The two energy storage mediums can store different quantities of energy. While modern batteries in electric vehicles have an average range of about 200 km, hydrogen gives a vehicle a range of about 500 km – comparable to conventional vehicles. It is just about as fast to fill up a hydrogen vehicle as a conventional vehicle. In around three minutes a hydrogen vehicle can be filled up and ready to hit the road again.
