Roujia Wen

Retrofittable cargo-ship carbon-capture system

China · United KingdomEvidence: high confidenceChecked July 2026

Roujia Wen co-invented a modular system that captures carbon dioxide from cargo-ship exhaust and binds it into solid limestone. The vessel-mounted unit is tangible emissions-control hardware, with claims confined to its tested retrofit and development context.

01

What Roujia did

Co-invented Seabound's modular cargo-ship exhaust carbon-capture system with Alisha Fredriksson.

02

Why it matters

The device gives existing commercial ships a physical path to reduce exhaust emissions without implying that it alone decarbonises shipping.

03

Living-status check

A dated 6 March 2024 account identifies Wen as a Seabound founder who travelled on an ocean freighter to test the carbon-capture device with Fredriksson.
