Shipping giant Maersk is teaming up with Danish energy company Ørsted on a new venture hoped to cut into the carbon emissions generated by vessels idling offshore. Their solution is a purpose-built charging buoy that supplies power to ships moored overnight, with the first demonstration expected to take place at an offshore wind farm towards the end of the year.

Shipping is a noteworthy contributor to the greenhouse gases accumulating in the atmosphere, responsible for around three percent of total emissions as vessels powered by fossil fuels carry cargo around the globe. And even when on standby, these vessels burn fuel for auxiliary operations, such as powering winches, air-conditioning systems or fuel pumps.

Through its spin-off venture Stillstrom, Maersk is looking to eat into these emissions by channeling clean and renewable energy instead. Idling ships can safely moor to the charging buoy, which is said to be large enough to charge a battery onboard a service operation vessel (SOV) […]
