Singapore’s energy mix is heavily dominated by natural gas, which accounts for approximately 93% to 95% of its electricity generation as of early 2025. While the nation is aggressively expanding its renewable capacity, particularly solar, non-fossil sources currently contribute less than 5% of the total electricity supply.

Singapore is rapidly advancing its green hydrogen strategy to meet up to half of its electricity demand by 2050 and achieve net-zero emissions. By 2026, Singapore will start incorporating hydrogen into its energy mix, with key projects including imported green ammonia/hydrogen, development of nine hydrogen-compatible power plants by 2030, and the nation’s largest electrolyzer on Jurong Island.

As of February 2026, there’s no information indicating that Singapore is producing green hydrogen from electrolysis of seawater.
