Thanks for post.
from the article..
When combined with liquid oxygen, a liquid methane engine offers higher performance relative to other storable propellants, better long-term storage potential relative to liquid hydrogen, and lower cost handling characteristics due to its environmentally safe nature, project officials said.
.....to save time.

We need better propulsion systems.

Alliant said it has completed testing of a 7,500-pound-force thrust liquid oxygen-methane workhorse engine. The test series provided valuable insights into LOX-methane engine ignition, startup, shutdown, nominal operation, off-nominal operation and dynamic combustion stability, according to the company.

Nice, an engine for in-space startup without the liquid hydrogen handling issues.
