GHGSat second-generation satellite
GHGSat's next methane satellite, designed to catch leaks half the size its current fleet can and cover twice the area per satellite each day.
Why it matters
Smaller leaks add up. Lowering the detection floor to 50 kg per hour onshore brings many more sites into view, which matters as methane rules tighten in the U.S. and Europe.
How the technology works
The company says each Gen2 satellite will detect onshore methane leaks down to 50 kg per hour (versus 100 kg per hour for its first generation) and image 20,000 square km a day. It is scheduled to reach orbit in early 2028.
