The two firms said in a joint statement on Wednesday that they delivered bio-LNG to a commercial container vessel, without providing further details.

The renewable natural gas (RNG) used to produce the bio-LNG was sourced from a Morrow Energy facility.

According to the duo, the RNG from this facility has a low certified carbon intensity of 7.74 grams of CO2e per megajoule of energy under the ISCC framework.

This loading operation serves as a “critical proof-of-concept” for the scalable deployment of bio-LNG in commercial shipping, demonstrating its immediate potential to decarbonize maritime transport, they said.

It follows a strategic agreement announced by the two firms in August to deliver renewable LNG, or bio-LNG, to customers on the west coast of North America.

The initiative builds on the first bio-LNG bunkering in the US that Anew Climate — then known as Element Markets — facilitated in 2021, Seaspan said.

In partnering with Anew Climate, Seaspan will expand its portfolio of offerings to include ISCC-certified R-LNG to customers all along the west coast of North America.

Earlier this year, Seaspan Energy completed what it says is the first ship-to-ship LNG bunkering operation in Canada.

During the operation in the Port of Vancouver, the 7,500-cbm Seaspan Lions, the second of three Seaspan Energy vessels, delivered LNG to the LNG dual-fuel tanker, Pacific Jade.

Before that, Seaspan Energy completed its first ship-to-ship LNG bunkering operation to a containership in the port of Long Beach.

The firm completed the first ship-to-ship transfer with Seaspan Garibaldi.

Seaspan Energy said this operation marked the beginning of its service offering on the west coast of North America.

China’s Nantong CIMC Sinopacific Offshore & Engineering handed over Seaspan Lions to Seaspan Energy in October last year.

Like its sister vessel, Seaspan Garibaldi, which CIMC SOE delivered in August, the newbuild is 112.8 meters long, 18.6 meters wide, 5 meters deep, and has a design speed of 13 knots.

In addition, CIMC SOE delivered Seaspan Energy’s third vessel, Seaspan Baker, earlier this year.
