A new technology can create crude oil in under an hour from algae. While there are already techniques to do this, they are expensive and slow, requiring drying the algae before turning it into oil. This new technique uses wet algae, so it is faster, and doesn’t use as much energy.
If this can be scaled up, then it solves one of the two main problems with oil synthesis from algae. The other is growing enough algae in the first place. Scientists are working on that problem.
Because algae uses carbon dioxide from the air, this method would be carbon neutral, or possibly even carbon negative because not all the carbon gets burned. Carbon that isn’t burned can be used in plastics, and that would be kind of like carbon sequestration.
Yes, there are many other problems that need to be worked out before this is close to feasible. But I like that the research is being done on methods like this. I’d like it even better if we can have a system that doesn’t have emissive pollutants.
