Proof of Usefulness Score
Gaining Momentum

ZEM Fuel Systems is a verified UK-based engineering firm (inc. 2018) developing high-value ammonia fuel cell solutions for maritime decarbonization, supported by significant government funding (~£2M Innovate UK grant). However, the project submission is of extremely low quality, containing false claims ('most people have used my product', 'audience: everyone') and vague details. While the underlying technology and market timing are excellent, the score is heavily penalized by the lack of verifiable commercial traction (currently in R&D/pilot phase) and the unreliable submission data.
