Equity Method Investments and Joint Ventures [Abstract]
Unconsolidated Subsidiaries	Unconsolidated Subsidiaries Each of our wholly owned Unconsolidated Subsidiaries, within the Coal Mining and NAMining segments, meet the definition of a VIE. The Unconsolidated Subsidiaries are capitalized primarily with debt financing provided by or supported by their respective customers, and generally without recourse to us. Although we own 100% of the equity and manage the daily operations of the Unconsolidated Subsidiaries, we have determined that the equity capital provided by us is not sufficient to adequately finance the ongoing activities or absorb any expected losses without additional support from the customers. The customers have a controlling financial interest and have the power to direct the activities that most significantly affect the economic performance of the entities. As a result, we are not the primary beneficiary and therefore do not consolidate these entities' financial positions or results of operations. See Note 1 for a discussion of these entities. The Investment in the unconsolidated subsidiaries and related tax positions totaled $16.0 million and $14.1 million at March 31, 2025 and December 31, 2024, respectively. Our risk of loss relating to these entities is limited to our invested capital, which was $5.5 million at March 31, 2025 and December 31, 2024. Earnings of unconsolidated operations were $15.4 million and $13.4 million during the three months ended March 31, 2025 and 2024, respectively. NACCO Natural Resources is a party to certain guarantees related to Coyote Creek. Under certain circumstances of default or termination of Coyote Creek’s Lignite Sales Agreement (LSA), NACCO Natural Resources would be obligated for payment of a make-whole amount to Coyote Creek’s third-party lenders. The make-whole amount is based on the excess, if any, of the discounted value of the remaining scheduled debt payments over the principal amount. In addition, in the event Coyote Creek’s LSA is terminated by Coyote Creek’s customers, NACCO Natural Resources is obligated to purchase Coyote Creek’s dragline and rolling stock for the then net book value of those assets. To date, no payments have been required from NACCO Natural Resources since the inception of these guarantees. We believe that the likelihood NACCO Natural Resources would be required to perform under the guarantees is remote, and no amounts related to these guarantees have been recorded.
