The global oil and gas storage market size stands at approximately $238.77 billion in 2026, according to combined analyst estimates, with the broader infrastructure market projected to reach $341.39 billion by 2035 at a CAGR of 3.64%. The figure encompasses liquid petroleum terminals, underground gas storage, strategic petroleum reserves, and floating storage assets worldwide.
Narrower estimates from Research and Markets and Research Nester, which focus specifically on above-ground oil storage infrastructure rather than the full asset base, place the standalone oil storage segment at $17.2 billion in 2026, growing to $23.4 billion by 2033 at a CAGR of 4.5%. The divergence between these figures reflects methodological differences in what analysts include — commercial terminals only versus the full strategic and floating storage asset base.
Oil and Gas Storage Market Size by Segment
The market breaks cleanly into two sub-sectors, each measured differently by analysts. The oil storage segment — covering fixed roof, floating roof, and spherical tanks at commercial and strategic facilities — is valued at $17.2 billion in 2026 by Research and Markets, with a 4.5% CAGR to 2033. Research Nester’s comparable estimate places it at $16.94 billion, growing to $24.63 billion by 2035.
The natural gas storage segment is measured primarily in capacity terms rather than asset value. Physical underground and above-ground gas storage capacity is projected to reach 484.23 billion cubic metres (bcm) in 2026, driven by power sector demand and LNG import growth. Capacity requirements are growing at a 4.53% CAGR, with projections exceeding 690 bcm by 2034.

What Is Driving Oil and Gas Storage Market Size Growth
Energy security is the dominant driver in 2026. Mid-year supply disruptions at key maritime chokepoints — including the Strait of Hormuz — have accelerated drawdowns of western inventories and driven up the premium on physical floating storage in the Middle East. Governments across Europe, Asia, and North America have responded by expanding strategic petroleum reserve capacity, directly adding to infrastructure capex.
China leads global onshore inventory holdings, commanding an estimated 31% of all commercial and strategic reserves according to data tracked by Ursa Space Systems via S&P Global. The United States accounts for approximately 11%, with Japan at 8%. This concentration of storage capacity in Asia-Pacific reflects both strategic reserve policy and the scale of refining infrastructure serving China’s domestic market.
OPEC estimates that the midstream oil logistics and storage sector requires $1.3 trillion in cumulative investment through 2050. High capital barriers, combined with tightening emissions standards, are pushing operators toward automation, retrofit programmes, and modular tank solutions rather than greenfield builds. Environmental compliance is itself becoming a capex driver, with floating roof systems and vapour recovery upgrades mandated under increasingly stringent regulations across Europe and North America.
Regional Breakdown of Oil and Gas Storage Market Size
Asia-Pacific is the fastest-growing region, driven by Chinese and Indian investment in refining infrastructure, LNG import terminals, and strategic reserves. The region’s combination of rising petroleum demand and limited domestic production makes import storage a structural requirement rather than a discretionary investment.
North America remains the most established market. The US shale boom has sustained demand for midstream storage capacity across the Permian Basin, Gulf Coast, and Midwest, while the strategic petroleum reserve modernisation programme continues to absorb federal capex. Europe’s market is shaped by gas storage obligations under EU energy security policy — member states are required to maintain minimum inventory levels, creating a regulatory floor for storage investment.
The Middle East and Africa segment is driven by export-oriented production. Large-scale refinery projects in Saudi Arabia, the UAE, and Kuwait require dedicated product storage at scale, and the shift toward floating storage to buffer OPEC production adjustments has increased demand for VLCC and ULCC-compatible marine terminal infrastructure.

Oil and Gas Storage Market Size: Key Players
Royal Vopak is the world’s largest independent tank terminal operator by capacity, operating approximately 40 million cbm across 22 countries. Stolt-Nielsen, Oiltanking, and LBC Tank Terminals are among the other major independent operators active across multiple continents. On the gas storage side, Snam in Italy and Uniper in Germany operate the largest regulated underground storage networks in Europe.
Equipment manufacturers serving the market include NOV Inc., CST Industries, ERGIL, and Fisher Tank Company — supplying fixed roof, floating roof, and spherical tank systems across commercial and strategic installations. The market is characterised by high asset concentration: a relatively small number of operators control the majority of commercially available storage capacity in each region.
Emerging market growth is drawing new entrants, particularly in Asia-Pacific and West Africa, where infrastructure gaps remain large and energy demand growth is outpacing existing capacity. Indonesia’s proposal for a dedicated ASEAN oil reserve hub in Sumatra — announced in 2026 — is an example of the state-led investment driving oil and gas storage market size growth across the developing world.
Oil and Gas Storage Market Size Outlook to 2033
The combined market trajectory points to sustained mid-single-digit growth through the early 2030s, supported by three structural factors: the continued expansion of LNG as a traded commodity requiring regasification and storage infrastructure; the growth of strategic petroleum reserves in economies exposed to supply chain risk; and the retrofit cycle in North America and Europe, where ageing tank infrastructure must be upgraded to meet current safety and emissions standards.
The global oil and gas storage market size is unlikely to contract meaningfully in any near-term scenario. Even in an accelerated energy transition, liquid hydrocarbon storage remains essential to petrochemical supply chains, aviation fuel logistics, and the management of crude differentials between production basins and refining centres. Gas storage, meanwhile, is increasingly positioned as the buffer layer for intermittent renewable generation — with underground caverns and LNG peak-shaving facilities integral to grid stability strategies across Europe and Asia.
The Research and Markets report, published April 2026, projects the standalone oil storage market growing from $17.2 billion to $23.4 billion by 2033. Broader estimates incorporating the full asset base, including gas storage infrastructure and strategic reserves, point to a combined oil and gas storage market size approaching $341 billion by 2035.
What is the global oil and gas storage market size in 2026?
The global oil and gas storage market size is estimated at approximately $238.77 billion in 2026 when the full asset base — commercial terminals, strategic petroleum reserves, underground gas storage, and floating storage — is included. Narrower estimates focusing on above-ground oil storage infrastructure alone place that segment at $17.2 billion in 2026, growing to $23.4 billion by 2033.
What is the CAGR for the oil and gas storage market?
The broader oil and gas storage infrastructure market is projected to grow at a CAGR of 3.64% through 2035. The standalone oil storage segment carries a slightly higher CAGR of 4.5% to 2033, according to Research and Markets. Natural gas storage capacity requirements are growing at 4.53% annually.
Which country holds the most oil and gas storage capacity?
China leads global onshore oil inventory holdings, accounting for approximately 31% of all commercial and strategic reserves worldwide according to data from Ursa Space Systems via S&P Global. The United States holds around 11% and Japan approximately 8%.
What is driving investment in oil and gas storage infrastructure in 2026?
The primary drivers are energy security concerns following supply disruptions at key maritime chokepoints, the expansion of strategic petroleum reserves across Asia, Europe, and North America, and the LNG import infrastructure build-out in Asia-Pacific. Environmental compliance requirements are also generating retrofit capex across ageing terminal networks in Europe and the US.
How much investment does the oil and gas storage sector need by 2050?
OPEC estimates the midstream oil logistics and storage sector will require $1.3 trillion in cumulative investment through 2050. High capital requirements and tightening emissions regulations are pushing operators toward automation and retrofitting of existing assets rather than new greenfield construction.
