Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
Interesting way they broke down the carbon emissions over the life of the car instead of just looking at efficiency of the fuels themselves.
“Lithium-ion battery production [for electric vehicles] is very energy-intensive. As an example, a 100kWh battery will give a potential range of 250 miles and, in order to produce that battery, it will take around 20 tonnes of CO2,” says Hunt.
“A typical battery lasts for 150,000 miles, so that equates to around 83g/km of CO2. Then, when you take into account charging over that same distance, the same battery car will deliver 124g/km of CO2 over its lifetime,” he explains.
In comparison, today’s hydrogen cars have life-cycle emissions that are at least as low. A recent study found a hydrogen car such as the Toyota Mirai emits around 120g/km of CO2 over its lifetime. But this can be brought significantly down when hydrogen is produced from renewables.
A common method of hydrogen production involves separating it from natural gas (using a process called steam methane reformation), but work is underway to obtain hydrogen from biomass, which would significantly cut the life-cycle emissions from hydrogen to around 60g/km CO2. This is below the level that EVs will achieve, even when electricity is sourced from renewable sources, because of the environmental costs of battery production.
Betteridge's Law of Headlines applies, "No" is the answer.
This is the way!
