The objective of the CHEK project (deCarbonising sHipping by Enabling Key technology symbiosis on real vessel concept designs), is to reduce emissions from maritime transport through the integrated use of forms of energy and low-carbon technologies. These include the use of hydrogen fuel, wind power, electric batteries, heat recovery, air lubrication, and new antifouling technology. Development work on how to design and operate ships is also included.

The 120 TEU Yara Birkeland is the world's first battery-electric container feeder for commercial use, and the ultimate goal of the project partners is to operate it as an autonomous vessel.
