The future of fuels – Biofuels

20 01 2010


Ethanol and other biofuels have come under a lot of heat especially during the 2008 food crisis as most of them are derived from alimentary crops like corn (US), sugar cane (Brazil) and palm oil (Malaysia and Indonesia). It is almost commonly accepted that to become a sustainable part of energy portfolio new technologies will have to come online – the infamous second generation biofuels (e.g. made out of cellulose).

Governments have high hopes for renewable fuels for both strategic and environmental reasons. That’s why countries like the US establish very ambitious mandates like the Energy Independence and Security Act of 2007. This regulation stipulates that by 2022 about a fourth of the daily demand of gasoline (total demand ˜400 million gallons) comes from renewable resources.

While this number is great news to stimulate technological innovation in second-generation fuels, a more pragmatic look at the future reveals some tough (yet surmountable) hurdles ahead. I don’t think I have much to add to the real challenges technology wise, so let’s pretend that we manage to secure ˜100 million gallon of renewable fuel per day. In addition, I will not get into the wells-to-wheels controversy as to whether biofuels are actually beneficial as a whole or not. Allow me to focus instead on operations, as I think it is an issue too often overlooked in the biofuels debate. Read the rest of this entry »
