However, since the amount of oil that can actually be used from a standard ton of algae is only around 28%, it’s far from the most cost-effective method available. There’s also the additional problem of removing CO2 contaminants before the process can even begin, which is currently accomplished through a high-energy, high-cost process. However, developments in Australia and the US are working to make algaculture viable. Continue reading
