Phillips 66 weighs Louisiana refinery expansion
Phillips 66 weighs Louisiana refinery expansion
Houston, 20 March (Argus) — US independent refiner Phillips 66 is seeking state tax incentives for a possible expansion of its 264,000 b/d refinery in Lake Charles, Louisiana. The expansion would increase production capacity and improve operational efficiency through upgrades and new specialized equipment, according to a summary of the project posted by the Louisiana Department of Economic Development. The agency, which administers state incentives, said that the Phillips 66 project is in review. Phillips 66 said today that it does not typically comment on refinery operations, regulatory filings or commercial activities. According to the Louisiana Department of Economic Development posting, the $99mn upgrade would include adding a 5MW steam turbine power generator, a boiler feedwater chemical system, LCR kerosene product rundown system upgrades, a reactor, a naptha fractionator, and other pieces of equipment. The budget includes $40mn for machinery and $59mn for labor and engineering. The project is estimated to be completed at the end of 2027.

ACBL sets release dates for Illinois River lock
ACBL sets release dates for Illinois River lock
Houston, 13 February (Argus) — Major barge carrier American Commercial Barge Line (ACBL) has issued its earliest release dates for Illinois River barges planning to transit the Lockport Lock, which closed for maintenance last month. Release dates will be from 23 February through 19 March for barges expecting to pass through the Lockport Lock over the spring season, ACBL said Wednesday. The US Army Corps of Engineers (Corps) expects to reopen the Lockport Lock on 25 March, the Corps said when it announced the closure . The Corps closed the lock on 28 January to install new vertical lift gates and make repairs. The closure has cut off major trade hubs such as Chicago, Illinois, and Burns Harbor, Indiana, from Illinois River barge transportation. Lock 27 and the Mel Price Lock above St Louis will remain partially closed through 1 April, as they are also undergoing maintenance by the Corps, ACBL said. The barge line acknowledged higher demurrage rates were likely for those who loaded barges prior to the released dates. Initial transit on the Illinois River is also anticipated to have a significant backlog in the spring months.

US PVC producers weigh cutbacks on lower margins
US PVC producers weigh cutbacks on lower margins
Houston, 30 January (Argus) — US polyvinyl chloride (PVC) producers are weighing operation cutbacks in February after grappling with deteriorating sales margins underpinned by elevated feedstock costs and stagnant end-product values. PVC producer profitability eroded in January as prices for key feedstock ethylene leapt to four-month highs by mid-January, various sources said. Ethylene is a main component in ethylene dichloride (EDC) manufacturing, which is then cracked into vinyl chloride monomer (VCM) before being converted into PVC. Some domestic PVC production is fully integrated and feature ethylene crackers, but many producers still purchase spot or contract ethylene and remain exposed to price fluctuations in the spot market. Spot US ethylene prices to-date in January have averaged 18pc higher than in December and 66pc higher than in January 2024, according to Argus data. Meanwhile, PVC spot values in Houston appreciated at a much slower rate between December and January, climbing by 1pc. Elevated ethylene spot prices are expected to persist in the near-term, maintaining pressure on PVC margins, due to planned maintenance and recovery from unplanned shutdowns in mid-January stemming from sub-freezing temperatures that gripped the US Gulf coast. The expectation for ethylene values to persist at current levels is anticipated to result in PVC production cutbacks, according to several exporters. Some producers, though, remain incentivized to maintain operating rates after bringing online expanded capacity last year. Formosa and Shintech collectively brought more than 500,000 metric tonne (t)/year of new PVC capacity on line during the second half of 2024. The ramp up in added capacity coincided with increasing trade barriers into key offshore destinations, which is expected to keep more volumes within the US while consumer demand outlooks this year remain cautiously optimistic . US buyers are unsure if domestic demand will be strong enough in 2025 to absorb additional volume, placing a ceiling on upward price direction. Exporters are even less optimistic operating in a global market increasingly defined by anti-dumping duties and plentiful Chinese supply. Domestic contract negotiations have highlighted the contrast between higher operating costs and a well-supplied PVC market. Producers cited higher operating costs to argue against lower contract negotiations in January, especially after prices fell in October and November. Several producers announced increases for February volumes, with some rising as high as 5¢/lb. But buyers said current demand does not support increases and instead view price hikes as to recapture lost margin. While producers sought price stability for January monthly contracts, they are also competing to lock in volume commitments through 2025 with aggressive annual contract discussions. Producers are trying to establish a price floor domestically by limiting price erosion among already-low-priced customers, but the additional capacity has made steeper price concessions difficult to avoid in other instances. One evolving upstream market variable is a firmer US Gulf coast spot export caustic soda market, which could encourage producers to maintain current rates and delay any cuts. Integrated PVC producers also manufacture chlorine and caustic soda through chlor-alkali units. Caustic soda is a co-product of chlorine — the latter a key feedstock in EDC production — and price swings in chlorine or caustic soda values can influence production decisions for PVC manufacturers. Caustic soda export prices from the US Gulf coast this week rose by $10/dry metric tonne (dmt) from the prior week and remains 8pc higher than the same week last year, according to Argus data. Tightened spot supply availability is a tailwind for spot values in the near-term, but values remain 24pc lower than peak levels in September when caustic soda prices last offset tighter PVC margins.

Global Li-ion battery shipments rise in 2024: EV Tank
Global Li-ion battery shipments rise in 2024: EV Tank
Beijing, 6 January (Argus) — Global shipments of electric vehicle (EV) power batteries and energy storage batteries surged in 2024, and could continue growing until 2030, according to Chinese research institution EV Tank. Global EV power battery shipments increased by 22pc on the year to 1,051GWh in 2024. This was mainly driven by continued rises in China's EV sales, which were supported by government incentives such as old vehicle trade-in subsidies, outpacing a slowdown in European and US markets caused by weakening economies and rising inflation. Global shipments of energy storage batteries rose by 65pc over the same period to 370GWh, supported by China's government-led promotion of energy storage systems in wind and solar industries, falling manufacturing costs, as well as firm physical demand in the US and effects from its investment tax credit. GWh-level orders from some emerging markets such as UK, Saudi Arabia and Australian also grew over 2024. Global total shipments of lithium-ion batteries increased by 29pc from a year earlier to 1,545GWh in 2024, including 1,215GWh in China that rose by 37pc on the year and accounting for 79pc of the total. Continued demand growth in China and the country's elevated investment in overseas production boosted global shipments. EV Tank forecasts global lithium-ion battery shipments will rise to 1,899GWh in 2025 and 5,127GWh in 2030. It also estimates China's shipments of sodium-ion battery shipments to more than double to 2GWh in 2024 from 0.7GWh in 2023. But this was far below earlier expectations of 3 GWh/yr, because of higher manufacturing costs for sodium-ion batteries compared with ternary and lithium iron phosphate lithium-ion batteries and lead-acid batteries. Consecutive falls in lithium carbonate feedstock prices in the past couple of years, mainly caused by rapid supply expansions, have reduced manufacturing costs for lithium-ion batteries. Current average manufacturing costs for lithium-ion batteries fell to 0.50 yuan/Wh as of June 2024, lower than Yn0.60/Wh for the sodium-ion battery, according to EV Tank.
