Alisha Fredriksson

Retrofittable cargo-ship carbon-capture system

Sweden · United KingdomEvidence: high confidenceChecked July 2026

Alisha Fredriksson co-invented a modular unit fitted to a cargo ship's exhaust stream that reacts captured carbon dioxide with limestone. The physical system was tested aboard a commercial vessel and is designed as retrofit equipment rather than as a shipping offset or software service.
