Spent an interesting morning yesterday on the Hammersmith Flyover, or rather at a BP filling station adjacent to it, where I learned about new biofuel developments that could help alleviate our dependence on ‘black gold’ in the future.

BP is experimenting with three new biofuel blends as part of its deal to fuel the Olympic fleet of BMWs. About 100 of the 4000 Olympic vehicles are running on mixes of conventional fossil fuel and plant-derived biofuels.

Biofuel is far from the only potential solution for keeping up with our ever-growing energy demands, but BP says advances in crop and conversion technology mean that production of it is becoming more efficient. That in turn makes it more viable as a commercial product and brings the cost down for producers and consumers – in theory, at least.
