What Exolum does

Exolum (formerly CLH, founded 1929 in Spain) is a privately held energy logistics company that owns and operates critical midstream infrastructure for liquid and gaseous energy products across 10 countries. Its core asset base includes more than 6,000 km of pipelines, 68+ storage terminals with 11+ million cubic metres of capacity, and aviation fuel operations at 50+ airports, with its densest networks in Spain (4,000+ km of pipelines) and the UK (2,000 km of pipelines serving Heathrow, Gatwick, Stansted, Manchester, and Port of Immingham).

The company generates revenue primarily through usage-based pipeline transportation fees, recurring storage terminal fees (including blending, transhipment, and break-bulk services), aviation fuel storage and into-plane fuelling contracts, and a growing portfolio of sustainable-energy services. These sustainable offerings include the world's first commercial-scale demonstration of Liquid Organic Hydrogen Carrier (LOHC) hydrogen storage at Immingham (up to 1 TWh potential), biomethanol bunkering infrastructure at Port of Immingham, CO2 storage terminals (Bristol Port, A Coruña, Huelva), a UK independent SAF blending facility at Redcliffe Bay, and the Avikor digital platform for passenger-purchased SAF certificates at Madrid Barajas Airport. Additional revenue streams include ENAC-certified metrology, additive services, NORM-waste management, and gas storage.

Exolum serves five primary customer segments: energy operators and oil companies (pipeline transport, bulk storage), airlines and airport operators (aviation fuel logistics and SAF), energy-transition companies (hydrogen, biomethanol, CO2, offshore wind support), industrial and petrochemical companies (specialised storage, metrology, waste), and maritime operators (biomethane bunkering). It is privately held, with Canadian pension fund OMERS divesting its ~25% stake in 2026 to Stoneshield Capital (~20%) and another global investment firm (~10%), and reported annual revenue exceeding €1.3 billion.

Direct peers

• Royal Vopak: Royal Vopak is the world's largest independent tank storage company, operating terminals for oil, chemicals, biofuels, and gases globally. Exolum and Vopak already partner in a 50/50 Houston ammonia terminal JV, validating direct operational and asset overlap in liquid bulk storage and emerging energy carriers.
• Magellan Midstream Partners: Magellan operates ~10,000 miles of refined petroleum pipelines and 54 terminals in the US. Comparable midstream liquids logistics business model, with terminal storage and fee-based pipeline revenues closely aligned with Exolum's core offering.
• Oiltanking: Oiltanking (a Marquard & Bahls subsidiary) operates one of the world's largest independent networks of tank terminals for petroleum products, chemicals, and gases. Directly comparable to Exolum in tank storage and pipeline logistics across Europe and globally.
• Buckeye Partners: Buckeye operates ~6,000 miles of pipelines and over 115 liquid petroleum product terminals across the US. Directly comparable midstream storage and pipeline services operator with similar fee-based revenue model.
• Inter Pipeline: Inter Pipeline operates oil sands, conventional oil, natural gas liquids, and bulk liquids storage and transportation infrastructure in Canada and Europe. Its bulk liquids terminals and NGL processing overlap directly with Exolum's bulk liquid storage business model.

Broad incumbents

• Kinder Morgan: Kinder Morgan is one of the largest North American energy infrastructure companies with ~82,000 miles of pipelines and ~140 terminals. Overlaps with Exolum in refined products storage and transportation but operates at much broader scale across multiple commodity streams.
• Vitol: Vitol is the world's largest independent energy trader with extensive midstream infrastructure investments in storage terminals and pipelines. Overlaps with Exolum in liquid bulk storage ownership and operations, particularly in Europe and the Americas.
• Shell Pipeline Company: Shell Pipeline operates thousands of miles of crude and refined product pipelines and terminals globally as part of Shell's integrated energy business. Overlaps with Exolum in refined product and aviation fuel logistics, though embedded within a much larger integrated oil major.

Regional players

• Tank & Rast: Tank & Rast operates Germany's motorway service stations and associated fuel logistics infrastructure. Although focused on retail fuel, the company handles bulk fuel logistics in Germany, providing a regional comparison point for Exolum's Mannheim and broader European operations.
• Navigator Gas: Navigator operates a fleet of petrochemical gas carriers and terminals primarily serving European and US petrochemical routes. Comparable in liquid/gas bulk storage and logistics but focused on maritime gas shipping rather than integrated pipeline networks.
