Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies (a) Legal Matters The Company is subject to various claims and legal proceedings covering matters that arise in the ordinary course of its business activities, including product liability claims. Management believes that any liability that may ultimately result from the resolution of these matters will not have a material adverse effect on the financial condition or results of operations of the Company. Please see Note 17(e) and (f) below for details regarding legal proceedings with Company suppliers. (b) Research Agreement Effective September 1, 2016, the Company is party to a research agreement with a third party, which is also a Company stockholder, whereby the third party will perform research activity as specified annually by the Company. Under the terms of the agreement, the Company paid a minimum of $400,000 annually in equal quarterly installments. For the nine months ended September 30, 2025 and 2024, $122,928 and $104,714, respectively, were paid under the research agreement. At September 30, 2025, $94,785 remained to be paid under the renewed agreement. (c) In-Licensing The Company was a party to a licensing agreement for non-exclusive rights to intellectual property which would expire at the later of the date at which the last patent underlying the intellectual property expires or 20 years from the sale of the first licensed product. Under the terms of the agreement, the Company would have had to pay up to an aggregate of $700,000 in royalties upon achievement of certain milestones. As of September 30, 2025 and December 31, 2024, no royalty expenses had been incurred under this agreement. The licensing agreement was replaced in November 2017, when the Company executed an agreement ("IP Acquisition Agreement") with the University of Delaware ("Seller") whereby all rights, title, and interest in the licensed intellectual property was assigned to the Company in exchange for an upfront fee of $500,000 and common shares valued at $1,491,556. The total acquisition cost of $1,991,556 was capitalized and is being amortized over the fifteen year expected life of the patents underlying the intellectual property. Under the terms of the agreement, the Company will pay up to an aggregate $7,500,000 in royalties to the Seller upon achievement of milestones, related to the aggregate number of vehicles that have had access to the Company’s GIVe platform system for a period of at least six consecutive months, and for which the Company has received monetary consideration for such access pursuant to a subscription or other similar agreement with the vehicle’s owner as follows:
Milestone Event: Aggregated Vehicles |  | Milestone Payment Amount
10,000 |  | $ | 500,000 |
20,000 |  | 750,000 |
40,000 |  | 750,000 |
60,000 |  | 750,000 |
80,000 |  | 750,000 |
100,000 |  | 1,000,000 |
200,000 |  | 1,000,000 |
250,000 |  | 2,000,000 |
|  | $ | 7,500,000 |
The Seller will retain a non-exclusive, royalty-free license, to utilize the intellectual property solely for research and education purposes. As of September 30, 2025, no royalty expenses had been incurred under this agreement. (d) Investment The Company is committed to possible future additional contributions to the Investment in Dreev (Note 5) in the amount of $270,000. (e) Purchase Commitments On July 20, 2021, Nuvve issued a purchase order (“PO”) to its supplier, Rhombus Energy Solutions, Inc. (“Rhombus”), for a quantity of DC fast chargers and dispensers for EVs (the “DC Chargers”), for a total price of $13.2 million. A dispute (the "Dispute") arose as to the PO, and an arbitration proceeding was initiated. On February 2, 2024 (the “Settlement Date”), the Company and Rhombus entered into a settlement and release agreement (the “Settlement Agreement”) pursuant to which, among other things, the Company agreed to pay Rhombus approximately $0.46 million for certain initial DC Chargers within 15 days from the Settlement Date. The Company further agreed to pay Rhombus an aggregate of $2.40 million for certain DC Chargers upon shipment with payments correlating to the amounts shipped due prior to shipment, a minimum of 50% of which shall be paid within 12 months after the Settlement Date, with the remaining balance, if any, to be paid within 24 months after the Settlement Date. The Settlement Agreement further provides for the dismissal of the legal action as to the Company and Rhombus. The Company and Rhombus agreed to release one another from any and all claims relating to the Dispute. On February 21, 2025, the Company initiated a legal action against Rhombus related to its refusal to honor certain warranty and commissioning obligations with respect to DC Chargers the Company purchased from Rhombus. Rhombus has in turn filed a demand for an arbitration claiming that the Company breached terms of the previous settlement agreement between the Company and Rhombus by failing to purchase additional DC Chargers. The Company believes it has no obligation to purchase additional non-conforming DC Chargers. Therefore, the Company believes that Rhombus’s position does not have any merit, and it intends to exercise all available rights and remedies in its legal action against Rhombus. The outcome of any such proceedings are inherently uncertain, and the amount and/or timing of any gains or expenses resulting from such proceedings is not reasonably estimable at this time.
