How credible is saltwater microalgae aviation biofuel and can it scale?

[StephenJ]

I was reading about a new type of **aviation** biofuel derived from a specific type of saltwater microalgae. The claim is it has a much higher energy density than traditional SAF and can be produced without using freshwater or farmland. It sounds almost too good to be true. Has anyone in the industry seen real data on this, or is it still just lab-scale hype? I'm curious about the practical hurdles for widespread adoption in commercial **aviation**.
