Carbon capture and storage (CCS)
Electric vehicles
Hydrogen fuel cells
Cars are fitted with hydrogen tanks that do not contain petrol or diesel
They have very high purchase cost because of the battery, but lower running costs
The fuel is combined with oxygen in the fuel cell, producing heat. This is used to generate electricity and drive an electric engine. The emissions from the vehicle are water vapour.
Nearly all is obtained from natural gas (methane), producing carbon emissions. The fuel can also be created by splitting water using electricity.
The CO2 is injected, which can enhance the recovery of oil from the field
The CO2 is liquified
A large drawback for many is the range the car can travel between charges – petrol cars can be quickly filled, versus long charging times, with limited access to charging facilities in some areas
There is a very high uptake in Norway, where they generate most of their power from hydro
The electricity they use must be sourced from renewable or low-carbon sources to benefit the environment. It’s no good generating the electricity in an inefficient coal-fired power station, especially when factoring in losses from distribution.
The CO2 is transported to an injection site (e.g. underground geology, an oilfield or the deep ocean)
CO2 is removed from the chimney
Limited scope for injection sites
Technology is still developing / experimental and is yet to have large-scale deployment - linked to some power stations
