US ethane production rose to a record last year on higher prices relative to natural gas, while exports and domestic consumption climbed to new highs on increased petrochemical demand, the US Energy Information Administration (EIA) said Thursday.
US ethane output in 2024 rose by 6.8pc to an all-time high of 2.83mn b/d, up from 2.65mn b/d in 2023, according to EIA data.
Most of the production increase came from the Permian basin, with Texas inland output increasing by 139,000 b/d to a record 1.58mn b/d and New Mexico refining districts rising by 9,000 b/d to 191,000 b/d, also a record. In the US east coast, the Appalachian No. 1 refining district, comprising much of the Marcellus shale formation in Pennsylvania and West Virginia, increased production by 37,000 b/d to a record 327,000 b/d, accounting for 12pc of total US production, up from 11pc in 2023.
The production hike resulted from higher rates of ethane recovery from the natural gas stream, EIA said. Recovery was incentivized as ethane prices strengthened relative to natural gas. During 2024, Mont Belvieu, EPC ethane's premium to its fuel value — based on day-ahead natural gas at the Waha hub in west Texas — averaged 17.91¢/USG, up from 13.64¢/USG in 2023, even as outright ethane prices averaged 5.55¢/USG lower at 19.02¢/USG, according to Argus data. The increase in Permian ethane recovery resulted in large part from negative Waha gas prices for large swaths of the year.
US consumption rises 8.4pc
Product supplied of ethane, a measure of domestic consumption, rose last year by 8.4pc to a record 2.33mn b/d, up from 2.15mn b/d in 2023, according to EIA data.
Consumption rose to records in the US east coast and Gulf coast regions, driven entirely by higher cracker operating rates, as no new ethane crackers came online during the year. Ethane consumption in the US Gulf coast rose by 109,000 b/d to 2.1mn b/d, while consumption in the US east coast nearly tripled to 103,000 b/d, up from 37,000 b/d in 2023. The east coast surge was driven by Shell's 1.6mn t/yr Monaca, Pennsylvania, ethane cracker ramping up production after coming online near the end of 2022.
Exports climb 4.5pc
US ethane exports last year rose by 4.5pc to a record 492,000 b/d, up by 21,000 b/d from 2023, the EIA reported.
China took the bulk of shipments and saw the largest increase in imports, spurred by increased petrochemical demand and ramped-up construction of import infrastructure. The US exported 227,000 b/d of ethane to China, up by 14,000 b/d from 2023. Ethane exports to Canada rose to 76,000 b/d, up by 11,000 b/d from 2023, while exports to India fell by 9,000 b/d to 65,000 b/d. Ethane shipments to Mexico averaged 21,000 b/d last year, up from 17,000 b/d in 2023.
The Asia-Pacific region last year took nearly 60pc of US ethane exports, followed by the Americas at just over 20pc and Europe at just under 20pc. The Americas were broadly responsible for most of the growth in imports from the US year-on-year, with receipts up by 17,000 b/d and the proportion of the total rising for the first time since 2020.
The proportion of exports going to the Asia-Pacific region fell for the first time since 2018, in part because attacks in the Red Sea slowed exports to India during the first half of 2024.
Ethane exports from the US are poised to rise further in the next three years, as Enterprise Products' new Neches River terminal in Texas, which will be able to ship up to 360,000 b/d of ethane or propane, is scheduled for operations in starting in 2026. Energy Transfer's Marcus Hook, Pennsylvania, export terminal, which can ship 75,000 b/d of ethane, is adding refrigeration to boost its capacity to 90,000 b/d.
