Bitumen / Asphalt Binder →

Petroleum-derived binder refined from extra-heavy crude oil (Venezuelan Orinoco, Canadian Alberta); constitutes 4-6% of asphalt mix by weight but is the quality and supply-constrained component

Canadian crude oil imports →

Heavy crude from Alberta oil sands and light crude from western Canada; 60% of US crude imports (4.1M b/d in 2024); processed at Gulf Coast and Midwest refineries that have been reconfigured for heavy crude — difficult to substitute with light crude quickly.

Crude Oil Feedstock →

Petroleum crude oil — the primary feedstock for gasoline and diesel production. US refineries process ~16.5 million bpd; domestic production meets ~80% of needs with ~20% imported. Crude quality (API gravity, sulfur content) determines the refinery configuration needed.

Diesel and Heavy Fuel Oil (underground mining and backup power) →

Underground mining equipment runs on diesel. Also critical for backup generation during Eskom load-shedding. Nornickel's 2020 Arctic spill (17,500 tonnes diesel) originated from a corroded storage tank at Thermal Power Plant No. 3, demonstrating diesel storage as infrastructure risk.

Electricity (Grid Power) →

Cryogenic air separation consumes 30–50% of variable operating cost in electricity. A 1,000 tonne/day oxygen plant draws ~20–30 MW continuously. Power outages directly halt production; many plants operate on interruptible power contracts creating vulnerability during grid stress events.

Electricity (Refinery Operations) →

Refineries are large industrial electricity consumers powering compressors, pumps, fractionation columns, and control systems. Hydrotreaters require significant power for high-pressure hydrogen recycle compressors. Grid reliability is critical — an unplanned outage can trigger emergency shutdowns.

Electricity (electrolytic refining) →

Electrical energy consumed in electrolytic copper refining cells. Refining alone consumes 250–300 kWh per tonne of cathode copper; total copper production (mine through cathode) consumes roughly 2,000–4,000 kWh/tonne depending on ore grade. Energy represents the largest operating cost in modern refineries.

Grid Electricity for PGM Smelting (South Africa / Russia) →

Electric arc smelting of PGM concentrate is among the most power-intensive steps in metallurgy. In South Africa, supplied by Eskom. Load-shedding cut 3–9% of annual PGM output in 2022–2023, with mines running 20–30% under capacity at peak Stage 6+. Russia's Norilsk grid is more stable but isolated.

Gulf Coast crude oil feedstock (jet fraction) →

Industrial electricity (high-voltage) →

Cryogenic ASUs are energy-intensive: typically 0.3–0.5 kWh per cubic metre of oxygen produced. Large ASUs consume 30–100 MW continuously. EU energy price spike in 2022 raised cryogenic O2 production costs ~15–25%. PSA systems are less energy-intensive but still require stable grid power — generator backup is essential in LMICs. Electricity interruptions are the leading cause of PSA system downtime in sub-Saharan Africa.

Interstate natural gas transmission pipelines →

High-pressure steel pipeline network (~305,000 miles) carrying processed gas from producing regions to population centers. FERC-regulated as common carriers. Compressor stations every 50–100 miles keep gas moving. No pipeline = no gas delivery regardless of how much is produced.

LNG peak-shaving and import facilities →

Approximately 70 utility-operated LNG facilities in the US (68+ BCF aggregate capacity). Liquefied gas stored in above-ground insulated tanks, vaporized during demand spikes. The Everett LNG import terminal in Boston (3.4 BCF storage, operated by Constellation) is the sole LNG import facility serving New England and receives tankers from Trinidad — a structural anomaly given New England's proximity to the Marcellus Shale.
