Subsequent Events [Abstract]
SUBSEQUENT EVENTS	14 – SUBSEQUENT EVENTS On February 6, 2026, the Company announced the suspension of development of the Permian Basin Project primarily as a result of changing market conditions driven by increasing demand for natural gas in the Permian Basin. See Notes 3, 4 and 5 for further information. On February 18, 2026, the Company announced a revised strategy to deploy its innovative and proprietary liquid fuels processing technology through capital-lite opportunities. The shift in strategy is intended to identify the most effective pathways to commercialize the STG+® technology with a disciplined approach to capital allocation. Related to its revised strategy, the Company has implemented and intends to continue implementing aggressive cost savings initiatives targeting a 50% reduction in costs in 2026 as compared to 2025. In connection with this initiative, the Company’s Board of Directors has created a Restructuring Committee and appointed director Jonathan Siegler as the sole member of that committee. The Restructuring Committee’s mandate includes overseeing all aspects of the Company’s revised strategy and evaluation of strategic alternatives while ensuring the Company remains fully NASDAQ-compliant. In connection with its cost savings initiatives, the Company is streamlining its Board of Directors. Related thereto, current directors Martijn Dekker and Dail St. Claire will not be standing for re-election at the end of their term. See Note 7 for further information. On February 27, 2026, Five Star Clean Fuels filed an original petition against the Company seeking a declaratory judgment that a letter agreement between a subsidiary of the Company and a predecessor of Five Star Clean Fuels constituted a binding contract that effectuates a grant to Five Star Clean Fuels of certain non-exclusive rights to utilize the STG+® technology. The petition primarily seeks non-monetary relief other than court costs and attorney fees. The Company intends to defend its position against the claim. At this time, the Company is unable to reasonably estimate a possible financial loss or range of financial loss, if any, that may be incurred to resolve this matter. See Note 7 for further information. On March 20, 2026, the Company announced the appointment of George Burdette as Chief Executive Officer (“CEO”) and engagement of Roth Capital Partners (“Roth”) as financial advisor to assist the Company in evaluating strategic alternatives. These announcements are part of the Company’s continued advancement of its previously announced restructuring and cost reduction initiatives. Mr. Burdette succeeds Ernie Miller who is stepping down from his role as CEO to pursue another opportunity. Mr. Miller will remain with the Company as a senior advisor. Mr. Burdette, who has served as the Company’s Chief Financial Officer (“CFO”) since October 2024, will also continue in that role. See Notes 7 and 9 for further information. Also subsequent to the year ended December 31, 2025, the Company extended its lease for its office and demonstration plant in Hillsborough, New Jersey for an additional year through April 2027.
