NEXTCHEM E MYTILINEOS FIRMANO ACCORDO PER STUDIO DI FATTIBILITÀ PER IMPIANTO DI IDROGENO VERDE IN ITALIA

NEXTCHEM AND MYTILINEOS AGREED TO CARRY OUT FEASIBILITY STUDY FOR GREEN HYDROGEN PLANT IN ITALY

• The Agreement relates to the execution of an engineering study to evaluate the implementation of a green hydrogen production facility based on electrolysis
• The project will involve the conversion of MYTILINEOS' power deriving from a photovoltaic power plant to green hydrogen
• NextChem will act as the engineering partner for the project

Milan/Athens, 20 May 2021 - Maire Tecnimont S.p.A. announces that its subsidiary NextChem and MYTILINEOS' Renewable and Storage Development Business Unit (RSD BU) have signed an agreement today to develop engineering activities for the implementation of a green hydrogen plant via electrolysis in Italy.

NextChem is Maire Tecnimont's subsidiary operating in the field of green chemistry and technologies for the Energy Transition. MYTILINEOS, through its RSD BU is a market leader in the development, construction and operation of utility-scale solar and hybrid power projects with a proven track record of over 1 GW of medium to large scale solar projects worldwide and battery storage installations.

Under the agreement, the RSD BU will leverage NextChem's and Maire Tecnimont Group's know-how and engineering expertise in hydrogen technologies to grow in the hydrogen business.

The project, which will convert renewable energy from one of MYTILINEOS' solar plants into green hydrogen, to be followed by other plants as well, aims to provide local off-takers with a carbon neutral energy carrier

alternative that could allow for effective decarbonization including in hard- to-abate industrial sectors.

Pierroberto Folgiero, Chief Executive Officer of Maire Tecnimont Group and NextChem, commented: "NextChem is a front runner in the development of a hydrogen-basedgreen economy: we have four technological solutions for hydrogen production in our portfolio, with different levels of carbon intensity. Among these, green hydrogen is the most ambitious one from an economic and environmental point of view and we are already working on it, both in Italy and abroad. This collaboration with MYTILINEOS is extremely promising and gives us the opportunity to demonstrate the benefits of an approach aimed at creating integrated platforms of plant solutions for the energy transition".

Nikos Papapetrou, General Manager of the RSD Business Unit stated: "Italy represents one of our key markets in Europe and we are excited to start the development of our first green hydrogen pilot project in partnership with Nextchem in the Country. We aim to expand this business model in all the countries where we are currently developing Renewable Energy Systems (RES). We are privileged to be able to provide our contribution to the green hydrogen energy strategy that has been worldwide identified as one of the main pillars of the energy evolution. Promoting the development of green hydrogen is a tangible demonstration of our commitment to accelerate the energy transition and decarbonization".

The development of the plant 's capacity for the green hydrogen production is of top priority, both for Italy and for the European Union, to contribute to the European goals of carbon neutrality and accelerate the energy transition in civil and industrial sectors.
