Don’t wait for a silver bullet to address maritime CO2 emissions says Inmarsat

The maritime industry, which carries over 90 per cent of world trade, accounts for 2.5 per cent of greenhouse gas emissions globally. To hit the target of a 50 per cent reduction in global shipping CO₂emissions by 2050, as set by the International Maritime Organisation (IMO), it is estimated that the sector will require investment of US$1.9tn, of which 85-90 per cent would be needed to build the infrastructure to support alternative future fuels.

A major new report – The Optimal Route – sponsored by Inmarsat shows that, to meet this objective, work on alternative maritime fuels infrastructure must continue at pace, but the shipping industry could reduce its greenhouse gas emissions by 38 per cent by 2050 through the digitalisation of existing vessels and shipping infrastructure alone. That is 76 per cent of the decarbonisation effort required by IMO at approximately 1/10^th of the overall estimated cost.

Ben Palmer, President of Inmarsat Maritime, the world’s leading provider of mobile satellite communications to the global shipping industry, said “Although a relatively low contributor of CO₂emissions the maritime industry still carries a heavy responsibility to do its part in the fight against climate change.

“The goals set by the IMO are ambitious and there is no shortcut or silver bullet to achieving such objectives. While alternative fuel solutions  are needed to continue to develop at pace, shipping can make considerable and rapid progress towards decarbonisation by embracing digital technologies. Initially driven by efficiency improvements and cost benefits, digital innovations can start making a major dent in vessel emissions today.”

The authors of the report, maritime innovation consultancy Thetius, said: “While they should not be considered in competition with each other, digital decarbonisation tools offer impressive value for money when compared to measures based on clean energy.” They warn the industry that “Carriers that do not step up their efforts now to invest in digital decarbonisation technology and embrace innovation, could find themselves redundant in the rapidly evolving ocean freight markets.”

According to the report, one of the most fruitful areas for digital decarbonisation is the voyage phase, when ships are at sea and their engines are at their most polluting.

Thetius data indicates that digital transformation in the area of ship operations and management technology is a growing sector, currently valued at US$11bn with voyage optimisation and fleet monitoring digital platforms returning impressive results already.

Solution provider Zero North revealed that its platform had prevented 218,000 tonnes of CO₂ from being released to the atmosphere throughout 2021, coinciding with a time when shipping’s emissions as a whole increased by 4.9 per cent.  While Cargill reported CO₂ reductions of up to 14.4 per cent across its tanker fleet. In the same year, artificial intelligence capability from Deepsea Technologies produced a 12 per cent reduction for capesize tanker operator Seanergy Maritime.

“The maritime industry is already seeing evidence of the environmental benefits of digitalisation, which is being delivered alongside commercial and operational improvements for ship owners and operators using the same technology and satellite communications infrastructure,” commented Palmer. “The journey the industry is embarked on is not an easy one but if we want to limit the damage human-driven emissions are doing to our planet, we have no choice. Inmarsat intends to play a central role in facilitating this transformation.”
