Singapore aims for climate neutrality after 2050, focusing on hydrogen as a key decarbonization enabler due to its limited renewable energy potential. The country's economy is heavily export-oriented, with industrial activities and the power sector contributing 46% and 39% of GHG emissions, respectively. Singapore is exploring low-carbon hydrogen for electricity generation, heavy-duty transport, and industrial fuel, while considering ammonia for maritime bunkering. While blue hydrogen is feasible, the lack of domestic geological formations for CO2 storage necessitates partnerships with neighboring countries. Singapore leverages its position as a global port and refining hub to aim for a future role as a hydrogen hub within a developing global supply chain.

Singapore established itself as a regional petroleum trading hub by combining a strategic geographical location with a 'twin-track' industrial strategy of minimal regulation and strong institutional support. Starting with oil refining in the 1960s, the government transitioned toward the petrochemicals sector in the 1980s via the 'cluster approach' at the Jurong Island Export Processing Zone. While facing challenges from regional competition, land scarcity, and environmental concerns, Singapore has maintained its edge through massive infrastructure projects, such as underground rock caverns for storage, and proactive policy adaptation.
