SAGT eyes more hybrid RTGs


South Asia Gateway Terminals (SAGT) wants to hybridise six more RTG cranes as part of its decarbonisation efforts.

South Asia Gateway Terminals (SAGT), a container terminal operator at the Port of Colombo and Sri Lanka’s first public-private partnership container terminal, has announced plans to hybridise six additional RTG cranes.

SAGT currently operates a fleet of 31 RTG cranes, with 22 already hybridised. According to the company, the hybridisation project has resulted in a significant reduction of GHG emissions in 2022/23, saving over 50% in diesel consumption per RTG move compared to the previous year. This effort translated into preventing over 3900 metric tonnes of CO2 equivalent emissions from entering the environment.

The hybridisation of RTGs was undertaken in response to the significant carbon footprint associated with RTG operations, which constituted 61% of SAGT’s scope 1 carbon emissions. Commencing with a pilot project in 2019, SAGT embarked on converting 22 RTGs from diesel-powered to hybrid technology, incorporating battery banks and lower capacity gensets. This initiative aimed to reduce daily diesel consumption and maintenance costs while advancing environmental sustainability.

“SAGT is currently exploring the feasibility of introducing a hydrogen fuel cell to replace the smaller diesel engine, potentially transforming the RTG into a zero-emission machine. Plans are also underway to electrify 30 prime movers from SAGT’s fleet, further reducing fossil fuel consumption,” the company said.

In addition, SAGT is investigating the installation of solar panels with a capacity of 461.6 kW on the roof of its office building. This initiative aims to generate approximately 7% of the annual power requirement for the company’s yard and building areas. Furthermore, the company is considering retrofitting existing diesel-powered forklifts to electric.

The company teamed up with Greenstat Hydrogen Sri Lanka in 2022 to conduct a feasibility study and develop net-zero infrastructure at the Colombo Port container terminal. The collaboration focused on exploring green hydrogen opportunities and integrating renewable energy solutions to decarbonise and electrify port operations in line with Sri Lanka’s net-zero targets.

SAGT is owned primarily by John Keells Holdings, which holds a 42% stake, along with other major shareholders including Evergreen Group, APM Terminals, and the Sri Lanka Ports Authority.
