Solazyme tests algae biodiesel that has superior performance under cold weather conditions (algae engineered to produce an oil with optimized fatty acid profile)
One way of bridging quality gaps is to blend biodiesel from different feedstocks?
We are still not yet there, but the clarity about the problems we face and the diversity of solutions being attempted make the goal look more reachable than ever before.
