Zero-carbon marine fuels that seek to deliver net well-to-wake emissions cuts will require a significant amount of renewable energy in a power system to have a positive impact over conventional fuels, the internal combustion engine industry has warned.
The global non-profit Association of the Internal Combustion Machinery Industry (Cimac) issued a white paper this week arguing that a full understanding of the overall climate impact of net-zero carbon fuels is only possible with a well-to-wake life-cycle perspective.
