A Stena Bulk tanker detained for 71 days by Iran during a diplomatic battle with the UK will become the first vessel fitted with on-board carbon capture technology as part of a ground-breaking study.

The 49,700-dwt Stena Impero (built 2018) will be upgraded from late 2023 in the first demonstration of carbon capture at full-scale in the shipping industry.

The Stena Impero gained international prominence after it was seized by Iran two weeks after British marines detained an Iranian VLCC, the 301,000-dwt Grace 1 (built 1997), in connection with the EU’s Syrian sanctions regime.
