O5 Marine vision

Climate change is the biggest challenge ever faced by humankind.

Today, the consensus is widely shared and accepted that we have no other options than to quit from fossil energies as fast as possible. In the maritime industry, the realistic alternative in short term is gas (we see the future of energy in bio-gas and other renewables).

O5 Marine assist ship-owners with innovative, responsible and cost effective models. We are specialized on gas-electric hybrid technologies to optimize the CO2 footprint of shipping.
