Active Energy Group Plc (AEG.L) develops and commercializes biomass products focused on sustainable energy solutions, primarily through its WoodBoost technology that enhances wood chip biomass for coal replacement in power generation and industrial applications; the company also pursues coal enhancement technologies and renewable energy projects. The firm operates in the renewable energy and biomass sector, targeting power utilities, industrial boilers, and clean energy markets primarily in the United States and United Kingdom. Founded in 2001 and headquartered in London, United Kingdom, Active Energy Group maintains production facilities in North Dakota, USA, with no major subsidiaries or parent company relationships publicly noted. Recent strategic developments include the continued commercialization of WoodBoost following its 2022 qualification by a major utility, alongside efforts to expand production capacity amid biomass market growth; however, the company faced operational challenges including a 2024 delisting risk from AIM due to share price suspension and ongoing efforts to secure funding for facility reactivation as of late 2025.
