Rising demand for natural gas and tighter supply of the fuel in the U.S. will likely pressure the commodity's Henry Hub benchmark prices in coming years, according to market watcher Wood Mackenzie. "The conditions that kept Henry Hub between $2 to $4 [per million British thermal units] for the best part of a decade are no longer...at full force," the energy-focused consulting firm says. It cites surging power consumption from data centers running artificial-intelligence systems and an expansion in U.S. capacity to export liquefied natural gas. Meanwhile, natural gas produced alongside crude oil at "near-zero marginal cost" will likely become scarcer as oilfields mature, the firm adds. "Associated gas accounted for roughly half of all U.S. gas supply growth over the past decade. Over the next 10 years, that share is expected to fall below 20%." (luis.garcia@wsj.com; @lhvgarcia)
