Subsequent Events [Abstract]
Subsequent Event	15. Subsequent Events Blue Point Joint Venture On April 8, 2025, we announced that we formed a joint venture, Blue Point Number One, LLC, with JERA Co., Inc. (JERA), Japan’s largest energy company, and Mitsui & Co., Ltd. (Mitsui), a leading global investment and trading company, for the construction, production and offtake of low-carbon ammonia. Upon formation, we held 40% ownership, JERA held 35% ownership, and Mitsui held 25% ownership in the joint venture. Under the terms of the joint venture’s limited liability company agreement, JERA has a conditional option to reduce its ownership percentage that expires on December 31, 2025. If the specified condition is met, JERA can reduce its ownership below 35% but not lower than 20%. We would have the right and obligation to increase our ownership by the same amount that JERA reduces its ownership. At our Blue Point complex in Ascension Parish, Louisiana, the Blue Point joint venture is expected to construct an autothermal reforming (ATR) ammonia production facility with a carbon dioxide (CO2) dehydration and compression unit to prepare captured CO2 for transportation and sequestration. Pre-construction activities and engineering evaluations at our Blue Point complex will begin in 2025. Construction of the ammonia production facility is expected to begin in 2026, with low-carbon ammonia production expected to begin in 2029. We will be responsible for the development, operation and maintenance of the ammonia production facility under contracts with the Blue Point joint venture. The three companies will offtake product according to their ownership percentages. We estimate that the cost of the low-carbon ATR ammonia production facility with carbon capture and sequestration technologies will be approximately $4 billion. Pursuant to periodic joint venture capital calls, the joint venture members will fund the cost of the facility’s engineering, procurement and construction according to their ownership percentages. The low-carbon ammonia production facility is designed with an annual nameplate capacity of approximately 1.4 million metric tons and is expected to capture greater than 95% of the CO2 generated from its production of ammonia. The ammonia production facility is expected to qualify for tax credits under Section 45Q of the Internal Revenue Code, which provides a tax credit per metric ton of CO2 permanently sequestered. In addition, we will invest approximately $550 million to build scalable infrastructure at our Blue Point complex to supply the ammonia production facility with services, including product storage and vessel loading. We will operate these facilities, and the Blue Point joint venture will compensate us for these services. We determined that Blue Point Number One, LLC is a variable interest entity (VIE) in which we hold a variable interest, and we are the primary beneficiary of the VIE as we have both (1) the power to direct the activities that most significantly impact the VIE’s economic performance, and (2) the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE, due to our 40% equity interest. As a result, we will consolidate this entity in our consolidated financial statements, with the combined 60% equity interest owned by JERA and Mitsui recorded as noncontrolling interest.
