US Natural Gas Update: Prices Strengthened on Forecast Heat in the East Next Week

By

US natural gas futures extended gains in after-hours trade on Friday to a six-week high due to an expected increase in cooling demand from the US East Coast next week.

Front-month Henry Hub futures and the continuous contract both rose by 2.32% to $2.961 per million British thermal units.

Weather forecaster Vaisala said Friday that above-average temperatures are expected across the Rockies and the East Coast for May 25-29, Barchart reported.

The expected heat wave is already leading to seasonal highs in natural gas demand from the power generation sector, the Energy Buyers Guide said in a Friday note.

"That consumption is approaching 35 Bcf per day for the first time since early March and is expected to hit new highs early next week as the heat peaks in the populous East," it said, adding that cooling degree day totals in the days ahead are expected to stay well below typical peak-summer levels, but the unusually early arrival of heat is drawing close attention from natural gas traders anticipating a potentially hotter-than-normal summer overall.

The market also drew support from expectations that the Strait of Hormuz will remain closed for the foreseeable future, following a high-level summit between US and Chinese leaders that failed to yield progress toward reopening the key shipping route. Continued disruptions could increase demand for US exports to help offset lost supplies from Qatar and the UAE.

Additionally, a lower-than-expected inventory injection boosted sentiment on Thursday when the US Energy Information Administration reported an 85 billion cubic foot injection into storage for the week ended May 8. The build fell short of analysts' expectations and was well below the 109 Bcf increase recorded in the same week a year earlier. The latest data left the storage surplus versus the five-year average at 6.5%, while the surplus over the year compressed to 2.3%, the EIA said.

According to Barchart, citing BNEF data, US gas production averaged 109.7 Bcf/d on Friday, up 3.2% year over year. Demand on Friday totaled 67.4 Bcf/d, an increase of 0.4% from a year earlier, and net LNG feedgas flows to US export terminals were estimated at 17.5 Bcf/d, up 1.9% week over week.

Carbon Capture Offers Fastest Route to Cleaner Data Centers, Wood Mackenzie Says

Carbon capture attached to gas-fired power plants offers the quickest way to reduce emissions from data centers as electricity demand could rise by 100 gigawatts to 200 GW by 2030, Wood Mackenzie said in a Thursday note.Data centers used about 450 terawatt-hours of electricity in 2025 and produced around 0.2 billion metric tons of carbon dioxide emissions annually, representing more than 0.5% of global emissions, the note said.Wood Mackenzie said steel, chemical, and cement industries emit far more carbon dioxide at 3.5 billion mt, 3 billion mt, and 2.3 billion mt annually, respectively, limiting the broader climate impact of cleaner data centers alone.US data centers currently emit 548 kilograms of carbon dioxide per megawatt-hour, or 48% above the national grid average, as artificial intelligence continues driving higher electricity consumption, according to Wood Mackenzie.Natural gas remains the primary source of near-term data center power additions, while all three major combined-cycle gas turbine manufacturers are expanding capacity after reaching full order backlogs, the note said."With gas power dominating buildouts right now and 58 GW already in development in Texas alone, the practical question isn't whether data centers will use gas, it's whether that gas will be decarbonized," said Peter Findlay, director of CCUS Analytics at Wood Mackenzie.Carbon capture systems can remove 92% to 98% of emissions from gas-fired plants, while developers can install the technology within three to four years or retrofit existing facilities within three to five years.The note estimated carbon capture would increase US gas-fired electricity costs by $15/MWh to $45/MWh after federal 45Q tax incentives, raising total power costs to roughly $115/MWh."At roughly $115 per MWh including capture, this represents a manageable premium for decarbonized power," Findlay said, adding that the technology is already commercially available and ready to scale.Enhanced geothermal systems could lower electricity costs to about $61 per MWh between 2030 and 2035, though only 1.5 GW are currently in the development pipeline.The note said restarted nuclear plants could generate decarbonized electricity at roughly $155 per MWh, although only 11.5 GW of retired nuclear capacity remains available in the US.Wood Mackenzie said long-duration energy storage technologies still face high costs of $100/MWh to $300/MWh, limiting their competitiveness against other low-carbon energy options.Wood Mackenzie said renewable energy and battery storage will remain important for cleaner power grids, although solar and wind alone cannot reliably meet constant data center electricity demand without significant natural gas backup."This isn't an either-or situation," Findlay said. "Renewables will help decarbonize the overall grid, which benefits everyone. But for data centers specifically - with their massive, constant power demands - you need firm capacity."Wood Mackenzie said hyperscalers are facing growing pressure to balance rapid expansion of artificial intelligence with long-term emissions-reduction commitments."Global data center emissions will increase," Findlay said, adding that strong balance sheets and public sustainability commitments will shape how hyperscalers address emissions over the coming decades.

US Natural Gas Update: Futures Climb on Small Inventory Build, Increased Cooling Demand Forecasts

US natural gas futures rose in after-hours trade on Thursday due to a smaller-than-expected storage build and supportive weather forecasts.Front-month Henry Hub futures and the continuous contract both rose by 1.96% to $2.92 per million British thermal units.The US Energy Information Administration reported an 85 Bcf increase in natural gas storage for the week ending May 8. The weekly inventory build was smaller than some forecasts as high as 91 Bcf, but largely in line with most analyst forecasts of an 84-87 Bcf build and close to the five-year average injection of 84 Bcf.Total working gas in storage climbed to 2,290 Bcf, with the surplus versus the five-year average holding near 140 Bcf. Inventories are now about 2.3% above year-ago levels and roughly 6.5% above seasonal averages, according to Trading Economics. By comparison, the same week last year recorded a larger storage injection of 109 Bcf.Weather forecasts also supported prices. Barchart, citing The Commodity Weather Group, said Thursday that forecasts turned warmer, with above-normal temperatures expected across the Midwest through May 18. The warmer outlook could lift natural gas demand from power utilities as air-conditioning use increases.Gelber & Associates said the latest forecast shift provides enough support for cooling demand to keep the market attentive to power-sector consumption, though not enough on its own to make the near-term decisively tight.BNEF data, cited by Barchart, showed US gas production fell to 107.6 Bcf/d on Thursday, down 2.2 Bcf/d from Wednesday, but up 1% from a year earlier.Lower-48 gas demand rose 3.7% year over year to 68.2 Bcf/d, up 400 million cubic feet per day from Wednesday.Feedgas flows to US LNG export terminals came in at 17.5 Bcf/d Thursday, down 1.8% from the prior week, but up 200 MMcf/d on the day. Gelber & Associates said "LNG remains the key swing factor outside of domestic weather, but net export demand is still running below recent monthly levels, and the market is waiting for fuller LNG service to restore a cleaner pull on feedgas."

Market Chatter: White House Weighs Gas Tax Cut as Iran Conflict Pushes Fuel Prices Higher

The White House is reviewing emergency fuel-price relief options as US gasoline prices remain above $4.50 per gallon during the Iran conflict, Reuters reported Thursday, citing people familiar with the matter.The Trump administration is considering suspending the federal gasoline tax, a move that could lower pump prices by 18 cents per gallon.Officials previously viewed the proposal as unnecessary, but growing fuel costs and economic concerns are increasing pressure on the administration to act.One person familiar with the discussions said the White House now believes Trump needs "a visible consumer relief move now" after gasoline prices jumped 50% since the war started.US consumer inflation rose to 3.8% in April, the highest level in nearly three years, while consumer confidence recently fell to a record low during the conflict, the report added.A Reuters/Ipsos poll conducted in May showed over 60% of Americans said rising gasoline prices had negatively affected household finances, while Trump's economic approval rating dropped to 30%.Republican lawmakers are growing concerned that higher fuel costs and economic pressure could damage the party's chances in November's midterm elections.White House officials are also tracking whether national gasoline prices could climb to $5/gal, according to the source, while American Automobile Association data showed prices have already crossed that level in seven US states.The White House did not immediately respond to' request for comment.(Market Chatter news is derived from conversations with market professionals globally.
