The traditional advantages of petroleum-based transport fuels are challenged by the need to lower atmospheric carbon. Despite significant research, development, and investment during the past few decades, humanity still seeks commercially viable carbon-neutral alternatives to petroleum. This paper presents approaches to carbon abatement using petroleum that have a strong chance to succeed in fulfilling technological and economic goals.
Comparing Renewable Fuel With a Fossil-Fuel/Carbon-Offset Combination
Typically, renewable liquid fuels are more expensive than their fossil fuel counterparts on a unit-energy basis, but they result in lower carbon dioxide (CO2) addition to the atmosphere. Fossil fuels could also be used in such a way that produced CO2 is sequestered at a cost.
