(“ATOME”, “the Company”, or “the Group”)
New joint venture in Central America
National Ammonia Corporation S.A

TOME Energy (AIM: ATOM), the only pure international green hydrogen and ammonia production
company on the London Stock Exchange with current large scale projects in Europe and South America
as well as hydrogen mobility projects, announces a new joint venture developing green ammonia and
fertiliser projects with the focus on Central America and the Caribbean.
ATOME has entered into a joint venture with Cavendish, the renewable energy arm of Grupo Purdy
S.A., one of the largest corporations in Costa Rica. ATOME and Cavendish have established a new
enterprise, National Ammonia Corporation S.A (“NAC”), owned equally with Cavendish and
headquartered in San Jose, the capital of Costa Rica, and which has a mandate to develop projects
across Central America and the Caribbean with its initial focus in Costa Rica.
Costa Rica is a democratic country and open economy and one of the greenest countries in the world.
The country has a 99% penetration of renewable electricity and a strong agriculture sector which is one
of the highest fertiliser consumers per hectare on the planet.
Cavendish, led by its CEO Silvio Heimann, is one of the the leading participants in the infant green
hydrogen market in Costa Rica with complimentary aims and objectives to ATOME. The objectives of
NAC align with ATOME which is focused on countries with renewable power resources and capabilities
combined with access to both domestic and international end markets. Costa Rica’s favourable position
with ports on both the Atlantic and Pacific only separated by some 200kms of landbridge make the
country a logistically excellent location.
Through NAC, ATOME aims to capitalise on its capability to roll out its large scale hydrogen and
ammonia production model now being implemented in Paraguay. In this regard, material and
constructive discussions are already taking place with relevant stakeholders in the areas of focus for
Olivier Mussat, CEO of ATOME, commented: “We are excited as to the potential of NAC. The
establishment of NAC shows the clear intent of ATOME to deploy its innovative business model and
know-how in other geographies.”
“With the Villeta Project in Paraguay, we have taken a significant industry lead that we are able to roll
out and replicate under the right conditions. Our partnership with Cavendish, a company established by
the founders and owners of Grupo Purdy, offers ATOME a very attractive opportunity with a strong local
partner to accelerate the development of a pipeline of international scale projects with strong local
demand for green fertilisers.”
Silvio Heimann, CEO of Cavendish, commented: “We are energised to join efforts with ATOME to
deliver innovative solutions to the domestic and regional markets, as this combination of international
expertise provided by ATOME´s team fits perfectly well with our ability to execute locally.”

Javier Quiros, partner in Cavendish SA and VP Grupo Purdy S.A., commented: “Cavendish was
established by the Quiros Family to boost the development of the green hydrogen technology in Costa
Rica and the region. We see this partnership with ATOME through NAC as a valuable opportunity to
bring our vision to life”.
