President Moon Jae-in says liquefied natural gas can be a substitute for coal and oil and aid the push to go carbon neutral.
Moon spoke on Monday at a christening ceremony for the 'Coral-Sul' floating LNG facility.
The offshore facility, or FLNG, which drills, refines, liquefies, stores and offloads LNG, will head to Mozambique.
"The world has its focus on LNG. It has the lowest carbon emissions among fossil fuel energy and with high development efficiency, it is the greatest low-carbon energy source that can replace coal and oil on the process toward carbon neutrality."
The Coral-Sul FLNG with a length of 432 meters and width of 66 meters is the world's second largest facility and capable of producing 3.4 million tons of LNG each year.
Samsung Heavy Industries won the 2.5 billion U.S. dollar deal to build it in 2017.
Moon highlighted the competence of South Korea's shipyards noting that all four of the world's FLNGs were made by the country.
He added that Seoul will upgrade its technology for eco-friendly ships as well as developing zero-carbon, smart vessels.
Also at the event was Mozambique's President Filipe Nyusi on a three-day visit to South Korea.
He is the first African head of state to visit the country since the pandemic began.
Moon expressed hope that once LNG production begins in Mozambique, this will be a symbol of friendly bilateral ties.
"The Coral-Sul, which sets sail tomorrow, will produce and ship 3.4 million tons of LNG annually in waters off Cabo Delgado, the hometown of President Nyusi. When LNG production gets under full swing, Mozambique's economic growth is expected at over 10% each year, while there's also expected to be simultaneous growth in the infrastructure and manufacturing sectors."
President Nyusi thanked South Korea for sparing no effort, saying that Mozambique will continue to become a destination for such investment.
He called for continued interest in Mozambique's development, adding that his country will also contribute to peace on the Korean Peninsula, and the world.
