Denmark’s AP Moller-Maersk is helping to develop a Berlin-based start-up that is claiming to have found a way to supply masses of cheap green methanol.

The partnership between C1 and Maersk Growth — the giant container line’s venture capital unit — aims to speed up mass production.

The size of the investment has not been revealed.

C1 said it has developed an ultra-efficient catalytic process to offer the low-carbon bunkers “without the usual premium paid for sustainably produced methanol”.
