Hydrogen | Low fuel cost to performance and works well in stop-start conditions. | Limited network of fueling stations in UK. Could be an impractical option, unless you live near a fueling station. | New technology. Not enough competition on prices yet. | Up to 300 miles per fueling. | H2O, Hydrogen & warm air. Fuel produced using only solar power has the best overall emissions. |
Electric plug in | Great fuel economy on short trips, only uses energy when moving. Idling at traffic lights doesn’t use fuel like petrol or diesel vehicles. | Limited range for motorway driving. | The maintenance costs are likely to come down quickly as we see more EVs on the roads. | < 150 miles per charge. This is only a problem if you do a high mileage. If you spend most of your time driving in a city or short commute, it could be perfect for your needs. | Depends on how the electricity has been generated. Best if you have your own solar panels at home to offset the extra need. |
Hybrid | This can vary a lot depending on what type of hybrid it is but is considerably better than petrol or diesel for city driving. | Better than a straight petrol engine as it is lighter. The cost will vary depending on whether it is a petrol or diesel hybrid. | Due to the mix of electric and combustion elements, this can cost marginally more on maintenance. | 300 > miles per fueling. If a hybrid plug-in: Electric only 15 – 53 miles range. Extended (using petrol/diesel engine) 150 – 500 miles range. | Depends on type of fuel used. But lower emissions than a petrol or diesel vehicle, as there are no emissions when in electric mode. |
Petrol | Generally cleaner than diesel engines. MPG (miles per gallon) of petrol engines are getting better, but are still less efficient than diesel engines. | Better on shorter trips. | An older technology, maintenance widely available meaning competitive pricing. | < 700 miles per fueling. | High CO2, compared to other technologies, plus a mix of harmful gases. |
Diesel | Diesels are designed for longer journeys and not stop-start traffic. | Highly efficient on motorway and open A road travel, or if carrying heavy loads. | Can be expensive if not driven as intended. A good option if you cover a lot of miles on open roads. | < 700 miles per fueling. | Can be high NOx (nitrogen oxides), unless using a Euro 6 engine, plus a mix of harmful gases. |
