<h1>Petrochemicals and Chemicals</h1> <p>Singapore's energy and chemicals (E&amp;C) sector — refining imported crude and feedstocks, cracking hydrocarbons into olefins and aromatics, and converting those building blocks into petrochemicals, specialty chemicals, and increasingly lower-carbon fuels and materials — is one of the city-state's oldest advanced-manufacturing clusters. The sector is promoted by the <a href="/en/knowledge/article/sgkb.business-industry.doing-business">Singapore Economic Development Board</a> (EDB) and physically centred on Jurong Island, a roughly 3,000-hectare amalgamation of seven southwestern islets completed in 2003 that hosts more than 100 global energy and chemicals firms linked by over 100 kilometres of shared pipelines (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>; see <a href="/en/knowledge/article/sgkb.geography-urban-planning.offshore-islands">offshore islands</a>). As of 2024, energy and chemicals contributed about 3% of Singapore's GDP and roughly one quarter of total manufacturing output — the second-largest manufacturing cluster after electronics — while employing more than 27,000 workers (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). Over three decades the sector attracted more than S$50 billion in investments, making Singapore a leading Asian chemicals hub despite having no domestic oil reserves (<a href="https://www.edb.gov.sg/en/our-industries/energy-and-chemicals.html">EDB industry page, accessed Aug 2026</a>).</p> <h2>Jurong Island and the chemicals cluster</h2> <p>Jurong Island is the physical heart of Singapore's petrochemicals and chemicals industry. The government combined seven small southwestern islands through staged <a href="/en/knowledge/article/sgkb.geography-urban-planning.land-reclamation">reclamation</a> into a single industrial landmass of about 3,000 hectares, with the amalgamation completed in 2003 (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>; <a href="https://www.jtc.gov.sg/about-jtc/news-and-stories/press-releases/jurong-island-celebrates-25-years">JTC, accessed Aug 2026</a>). JTC Corporation develops and manages the island's industrial infrastructure — roads, jetties, utilities, and common pipeline corridors — while EDB leads investment promotion for the energy and chemicals sector (<a href="https://www.jtc.gov.sg/about-jtc/news-and-stories/press-releases/jurong-island-celebrates-25-years">JTC, accessed Aug 2026</a>).</p> <p>The island's competitive advantage is integration rather than resource endowment. More than 100 kilometres of pipelines let refiners, crackers, and downstream chemical plants exchange feedstock, intermediates, and utilities without repeated loading and unloading, lowering logistics cost for export-oriented production (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). Many firms operate across both Jurong Island and mainland or nearby island sites, with derivative chemical units often linked to refining and cracking assets by subsea or shared corridors. Access to Jurong Island is controlled for safety and security; the island is an industrial zone, not a public recreation destination (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>; <a href="/en/knowledge/article/sgkb.geography-urban-planning.offshore-islands">offshore islands</a>). Port connectivity and Singapore's free-trade agreement network support the cluster's export orientation (see <a href="/en/knowledge/article/sgkb.business-industry.maritime-and-port">maritime and port</a>).</p> <h2>Economic scale within manufacturing</h2> <p>The energy and chemicals cluster sits within Singapore's broader chemicals manufacturing statistics tracked by SingStat and framed by EDB. In 2024, chemicals accounted for about 23% of Singapore's manufacturing output of S$423.6 billion and about 16% of manufacturing value added of S$114 billion (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). EDB's industry overview similarly characterises Energy &amp; Chemicals as contributing about 22–23% of total manufacturing output and hosts headline investment and employment anchors — including S$60 billion-plus cumulative fixed-asset investment commitments cited from SingStat series and more than 27,000 skilled workers (<a href="https://www.edb.gov.sg/en/our-industries/energy-and-chemicals.html">EDB industry page, accessed Aug 2026</a>).</p> <p>Output is cyclical and feedstock-sensitive. Refineries and steam crackers sit at the upstream end of the value chain; downstream plants turn intermediates into plastics, fibres, lubricants, coatings, and specialty materials used in electronics, pharmaceuticals, and consumer goods. Because Singapore imports virtually all crude and naphtha feedstock, shipping and regional price shocks transmit quickly into local crackers and chemical manufacturers (<a href="https://www.edb.gov.sg/en/our-industries/energy-and-chemicals.html">EDB industry page, accessed Aug 2026</a>). Government and EDB framing expects specialty chemicals — higher-margin, application-specific products — to grow faster than bulk chemicals globally over 2025–2030, which is why new project promotion emphasises specialty and sustainable materials rather than adding undifferentiated commodity capacity (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>).</p> <h2>Energy and chemicals relationship</h2> <p>Singapore treats &quot;energy and chemicals&quot; as one industrial cluster because refining, cracking, fuel production, industrial gases, and chemical derivatives share sites, pipelines, utilities, and investment promotion under EDB and JTC (<a href="https://www.edb.gov.sg/en/our-industries/energy-and-chemicals.html">EDB industry page, accessed Aug 2026</a>). That industrial cluster is distinct from — but tightly coupled to — the national electricity system described in <a href="/en/knowledge/article/sgkb.environment-sustainability.energy-and-power-grid">energy and power grid</a>: Jurong Island hosts large process plants that consume power and steam, while also hosting grid-facing assets such as solar arrays, utility-scale batteries, and pilots for hydrogen, ammonia, and other new fuels that may eventually feed both industrial processes and power generation (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>).</p> <p>The Energy Market Authority (EMA) appears in the island's next-generation energy agenda — for example through renewable-energy requests for proposals with JTC and ammonia exploration with the Maritime and Port Authority — while day-to-day fuel-mix and wholesale-market rules for the national grid remain in EMA's electricity remit (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>; <a href="/en/knowledge/article/sgkb.environment-sustainability.energy-and-power-grid">energy and power grid</a>). Close to 300 hectares on Jurong Island have been set aside for next-generation energy infrastructure, and about 20 hectares for a low-carbon data-centre park with potential capacity of up to 700 megawatts, illustrating how industrial land, power planning, and chemicals strategy now intersect (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-25-years-with-new-low-carbon-partnerships.html">EDB partnerships release, accessed Aug 2026</a>). Readers asking about household tariffs, the Open Electricity Market, or national fuel-mix percentages should use <a href="/en/knowledge/article/sgkb.environment-sustainability.energy-and-power-grid">energy and power grid</a>, not this cluster article.</p> <h2>Major operators and the value chain</h2> <p>Singapore's E&amp;C value chain spans upstream refining and cracking, midstream olefins and aromatics, and downstream specialty and performance chemicals. ExxonMobil operates a large integrated refining and chemical complex in Singapore, including a chemical plant first commissioned in 2001 and subsequent expansions in aromatics, resins, and elastomers; company materials also describe a multi-billion-dollar Resid Upgrade Project framed under Sustainable Jurong Island to convert heavier refinery streams into higher-value products (<a href="https://corporate.exxonmobil.com/locations/singapore/our-operations">ExxonMobil, accessed Aug 2026</a>; <a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>).</p> <p>Shell historically operated the other major integrated Energy and Chemicals Park spanning Pulau Bukom and chemical units on Jurong Island. On 1 April 2025 Shell completed the sale of that park to CAPGC Pte Ltd, a joint venture majority-owned by Indonesia's Chandra Asri Group and minority-owned by Glencore; operations transferred to Aster Chemicals and Energy Pte Ltd, branded as the Aster Energy and Chemicals Park (<a href="https://www.shell.com/news-and-insights/newsroom/news-and-media-releases/2025/shell-completes-sale-of-interest-in-singapore-energy-and-chemicals-park.html">Shell, accessed Aug 2026</a>; <a href="https://www.reuters.com/markets/deals/shell-completes-sale-singapore-refining-assets-chandra-asri-glencore-group-2025-04-01/">Reuters, accessed Aug 2026</a>). The Bukom and Jurong Island plants continue operating under the new ownership; answers that still treat Shell as the owner of Bukom after April 2025 are outdated (<a href="https://www.reuters.com/markets/deals/shell-completes-sale-singapore-refining-assets-chandra-asri-glencore-group-2025-04-01/">Reuters, accessed Aug 2026</a>).</p> <p>Beyond the integrated majors, Jurong Island hosts firms such as BASF, Chevron Oronite, Mitsui Chemicals, Sumitomo Chemical, SABIC, Arkema, Evonik, Linde, and Air Liquide across lubricant additives, elastomers, industrial gases, and specialty materials (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). Since 2021, EDB has tracked more than 30 new specialty-chemicals projects from firms such as Arkema, Cariflex, and Kuraray, expected to create more than 1,000 jobs when fully realised (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). EDB also counts oilfield equipment and services within the broader Energy &amp; Chemicals portfolio, with that segment alone generating over S$5 billion in output (<a href="https://www.edb.gov.sg/en/our-industries/energy-and-chemicals.html">EDB industry page, accessed Aug 2026</a>). Firm-level nameplate capacities change with projects and should be read from operator publications rather than treated as a single national production total.</p> <h2>Environmental and regulatory touchpoints</h2> <p>Chemical manufacturing on Jurong Island and elsewhere in Singapore sits under environmental and safety rules administered primarily by the National Environment Agency (NEA), alongside industrial estate planning by JTC and investment promotion by EDB. NEA controls environmentally hazardous chemicals under the Environmental Protection and Management Act (EPMA) and the Environmental Protection and Management (Hazardous Substances) Regulations: parties who import, sell, or export controlled hazardous substances must hold a Hazardous Substances Licence, and transport above specified quantity thresholds requires a separate transport approval (<a href="https://www.nea.gov.sg/our-services/pollution-control/chemical-safety/hazardous-substances">NEA hazardous substances, accessed Aug 2026</a>).</p> <p>Planning control is an earlier gate. NEA's Development Control and Licensing Division assesses proposed industrial allocations — JTC and HDB consult the division — so that siting, emissions, and pollution-control measures are acceptable before plants proceed; major developments may be required to complete pollution-control assessments, and industries need written permissions, licences, and permits before operations start (<a href="https://www.nea.gov.sg/our-services/pollution-control/chemical-safety/control-strategies">NEA control strategies, accessed Aug 2026</a>). For road movements of controlled hazardous substances, NEA specifies approved routes and timings; within Jurong Industrial Estate, Tuas Industrial Estate, and Jurong Island the approved window is 7 a.m. to 7 p.m. daily, with different hours for other areas, and drivers must meet training and emergency-response requirements (<a href="https://www.nea.gov.sg/our-services/pollution-control/chemical-safety/hazardous-substances/management-of-hazardous-substances">NEA management of hazardous substances, accessed Aug 2026</a>).</p> <p>Large process plants are also in scope for Singapore's carbon tax under the Carbon Pricing Act. The tax applies to industrial facilities with annual direct greenhouse-gas emissions of at least 25,000 tonnes of carbon dioxide equivalent (tCO₂e); the rate is S$25 per tonne for emissions years 2024 and 2025, rising to S$45 per tonne for 2026 and 2027, with a view to S$50–S$80 per tonne by 2030 (<a href="https://www.nea.gov.sg/our-services/climate-change-energy-efficiency/climate-change/carbon-tax">NEA carbon tax, accessed Aug 2026</a>). Manufacturing facilities are among the prescribed sectors, so energy-intensive refining and chemicals sites that cross the taxable threshold must register, measure, report, and pay accordingly — a direct cost overlay on cluster competitiveness that sits alongside EDB's Resource Efficiency Grant for Emissions (REG(E)) and the Sustainable Jurong Island decarbonisation agenda (<a href="https://www.nea.gov.sg/our-services/climate-change-energy-efficiency/climate-change/carbon-tax">NEA carbon tax, accessed Aug 2026</a>; <a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>).</p> <h2>Government strategy and Sustainable Jurong Island</h2> <p>Singapore's petrochemicals cluster was deliberately built from the industrialisation era onward rather than from domestic oil endowment: Jurong's industrial estate model was later scaled offshore through the Jurong Island amalgamation, with EDB coordinating investment promotion and land allocation with JTC (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>; <a href="https://www.jtc.gov.sg/about-jtc/news-and-stories/press-releases/jurong-island-celebrates-25-years">JTC, accessed Aug 2026</a>). In 2021 the government launched the Sustainable Jurong Island plan to pivot the sector toward specialty chemicals, sustainable materials, circular feedstocks, and new energies while keeping existing assets competitive (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>).</p> <p>EDB's REG(E) scheme had awarded 35 industry projects by the October 2025 Jurong Island anniversary releases, spanning energy efficiency, alternative fuels, wastewater biotreatment, and carbon capture, utilisation, and storage (CCUS); completed projects from firms such as Evonik, ExxonMobil, Linde, and Air Liquide are expected to abate more than 340 kilotonnes of carbon dioxide per year (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). Singapore's refineries and crackers rank within the top half of global peers for energy efficiency on Solomon Associates benchmarking and are working toward top-quartile performance (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). These industrial-policy tools sit alongside the broader <a href="/en/knowledge/article/sgkb.environment-sustainability.green-plan-2030">green plan 2030</a> Green Economy framing that positions Jurong Island as a sustainable energy and chemicals park.</p> <h2>Strategic trade-offs and critical perspectives</h2> <p>Jurong Island's integration creates a genuine policy trade-off. Shared pipelines, utilities, and port links can improve efficiency and support high-value manufacturing, but the same concentration also places land, safety, emissions, and infrastructure risks in one tightly connected industrial system (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>; <a href="https://www.nea.gov.sg/our-services/pollution-control/chemical-safety/control-strategies">NEA, accessed Aug 2026</a>). The cluster's GDP and manufacturing contribution therefore should not be read as a complete account of its public value: the relevant comparison also includes hazardous-substance controls, carbon costs, land opportunity cost, and the safety of workers and surrounding communities.</p> <p>Decarbonisation introduces a second tension between transition and continued production. Carbon pricing and efficiency grants create incentives to reduce emissions, while new fuels, carbon capture, circular feedstocks, and electrification require infrastructure, investment, and credible measurement before they can replace established processes (<a href="https://www.nea.gov.sg/our-services/climate-change-energy-efficiency/climate-change/carbon-tax">NEA carbon tax, accessed Aug 2026</a>; <a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). Claims that the cluster is becoming “low-carbon” should therefore specify the baseline, emissions boundary, abatement achieved, and time horizon; a project pipeline or target is not the same as verified economy-wide emissions reduction.</p> <h2>Decarbonisation and the next phase</h2> <p>The global shift away from transport fuels and toward lower-carbon chemicals is reshaping Jurong Island's investment pipeline. Under the Sustainable Jurong Island plan, the sector's output of sustainable products had grown 1.4 times since 2019 as of the October 2025 anniversary communications, on track toward a 1.5-times target by 2030 (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). Concrete island assets illustrate the direction: Sembcorp operates Singapore's largest utility-scale energy storage system on Jurong Island at 326 megawatt-hours, alongside the island's largest solar deployment at 118 megawatts peak; EMA and JTC have advanced renewable-energy requests for proposals including a 40 megawatt-hour vanadium redox flow battery pilot (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>).</p> <p>A*STAR's S$62.5 million Low Carbon Technology Translational Testbed (LCT3) on Jurong Island offers modular pilot bays for firms to scale CCUS, electrification, and circular-plastics technologies (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). For carbon capture, the government partnered with an S-Hub consortium of Shell and ExxonMobil to study a cross-border CCS project capable of storing at least 2.5 million tonnes of carbon dioxide per year when fully developed, supporting a national target of at least 2 million tonnes captured by 2030 (<a href="https://www.edb.gov.sg/en/about-edb/media-releases-publications/jurong-island-marks-twenty-five-years-of-low-carbon-innovation.html">EDB, accessed Aug 2026</a>). The petrochemicals and chemicals industry's long-term viability in Singapore depends on converting a legacy refining hub into a higher-value, lower-carbon chemicals and new-energy testbed — a transition EDB and JTC are actively funding rather than leaving to market exit alone (<a href="https://www.edb.gov.sg/en/business-insights/insights/how-singapores-jurong-island-is-powering-the-future-of-low-carbon-innovation-in-energy-and-chemicals.html">EDB insight, accessed Aug 2026</a>).</p>
