The Navy is supporting biofuel algae research in order to reduce the cost of green fuel. Do green ships project sea power?The Navy is supporting research at Arizona State University aimed at reducing the cost of biofuel to around $3.50/gallon. The Navy’s objectives are 10%-50% biofuel in its fuel mix. I’m hard pressed to see how using a limited production fuel like biofuel instead of a readily available fuel from petroleum enhances readiness or the real mission of the Navy. Sooner or later, if we keep plugging money into biofuel from algae, we may get a process that is almost economical.
