Philippine aerospace startup looks to algae as feedstock for rocket fuel

In the Philippines, ABS CBN news reports that OrbitX, the country’s first space start-up, is developing reusable rockets that will be fueled by liquid methane produced from biogas that uses algae as feedstock. The rockets will fly on a mixture of liquid methane with liquid oxygen. The Philippines recently created a national space agency but those launches are handled by international agencies due to lack of domestic capacity so the startup is looking to fill that gap.
