Algae Biodiesel vs. Cellulosic Ethanol - an interesting comparison

You are at: Oilgae Blog.

Here are some comparisons:

(1) Algae can be converted into ethanol or diesel, depending on the process.
(2) Cellulose feedstock, generally speaking, has a much larger geographic footprint than proposed algae designs.
(3) Both algae and ethanol can be grown utilizing waste streams.
(4) Cellulosic feedstock for ethanol is available now. Algae feedstock is not clearly ready.
(5) For both of these very promising feedstocks, algae and cellulose, we are going to wait a few more years before we’ll hopefully get a clear indication as to whether or not they truly emerge as major sources of transportation fuel.

This report does not consider converting algae to ethanol, from what I understand but rather does a direct comparison between different feedstocks for ethanol and for biodiesel (algae). However, it is an interesting article.
