About ATOME

ATOME Energy PLC is an AIM listed company targeting green hydrogen and ammonia production with over 500-megawatt of projects in Paraguay, Iceland and Central America.

Since its admission to AIM in December 2021 ATOME has signed its first electrolyser purchase order for its hydrogen transport Mobility Division due to start generating revenue in 2023 and signed a 120MW power purchase agreement with ANDE, the state energy company in Paraguay for production of green hydrogen and ammonia targeted to start operations in 2025. It has procured 30 hectares of land in Villeta, Paraguay for that facility, mandated Natixis Corporate Investment Bank and the multilateral IDB Invest to lead the project funding and the FEED study is currently underway with the international companies Urbas and Casale.

In December 2022, ATOME entered into a joint venture with Cavendish, the renewable energy arm of the substantial and well-established Purdy Group based in Costa Rica and formed The National Ammonia Corporation S.A, which is owned equally by ATOME and Cavendish.

ATOME is in the process of operational planning, sourcing and negotiations with green electricity suppliers, equipment providers and offtake partners, including signed memoranda of understanding and cooperation agreements in place with key parties, to use electricity generated from existing geothermal sources in Iceland and hydroelectric power in Paraguay and Costa Rica. All chosen sites are located close to the power and water sources and export facilities to serve significant domestic and then international demand.

The Company has a green-focused Board which is supported by major shareholders including Peter Levine, Trafigura, one of the world's leading commodity and logistics company, and Schroders, a leading fund manager.
