AP Moller-Maersk has signed a collaboration deal with Spain that will secure a huge amount of green methanol for its new container ships.

Soren Skou, the chief executive of the Danish owner, met Spanish Prime Minister Pedro Sanchez to thrash out the agreement.

“Signing the protocol marks a significant milestone in the collaboration that, if implemented in full, could deliver up to 2m tonnes of green fuels per year,” Maersk said.
