This report describes the results of an archaeological evaluation carried out at the former power station at High Marnham, Nottinghamshire on the 19th and 20th March 2024. The aim of the work was to evaluate the archaeological potential of the proposed development area and to inform possible mitigation measures, as required as a condition for planning permission for a hydrogen plant on the site. A series of made ground and modern industrial waste layers were revealed during the evaluation; these were probably associated with the former power station on the site. No archaeological features were identified during the work.
