Documented cause
LiqTech International developed silicon carbide ceramic membranes for filtration of marine scrubber washwater, which became highly relevant when IMO 2020 sulfur regulations took effect, requiring ships to either use low-sulfur fuel or install scrubbers. The company went public on NASDAQ and raised significant capital anticipating a massive scrubber retrofit wave. When shipping companies overwhelmingly chose to simply switch to compliant fuel rather than install scrubbers, LiqTech lost its primary market. Revenue collapsed, the company burned through its public market capital, and filed for bankruptcy in Denmark in 2023.
Lesson
“Cleantech companies that depend on regulatory-driven adoption must model multiple compliance pathways, not just the one that creates demand for their product. Shipping companies had a cheaper alternative to LiqTech technology, and they took it.”
