Alt Fuel #4 – Carbon-neutral petrol derived from algae

This one’s a very interesting option, and one of my personal favourites. This is a way of deriving petroleum from algae, though it’s still in its early stages.

– The carbon released from burning petrol made from algae is the same carbon the algae absorbed while growing. Thus, it’s carbon neutral.
– No big change is needed for this. No need for big overhauls or cullings of old cars, you still pump in petrol or diesel the same way.
– Less or no dependency on fossil oil. Adios, oil.

– Very limited in potential success as it’s so new. To be fair, it’s just taken off as an idea, and we’re still far from it being a viable alternative for conventional petroleum. Though when I first wrote about this solution, it was a whimsical notion, and has actually advanced, so that’s promising.
– The amount of algae needed to compete with fossil oil is staggering, and would imply a huge industrial shift. Let’s assume we do move into an age of algae-based petrol. Unless existing oil refineries ans infrastructures can be adapted, we’re looking at a lot of scrapping, waste and expensive investments.
