Green hydrogen refers to hydrogen produced by splitting water into hydrogen and oxygen using electricity generated from renewable sources such as solar or wind, avoiding direct CO2 emissions from production.[6] In Tarragona, the plant will use electricity from dedicated photovoltaic installations operated under an off‑grid or autoconsumption scheme to power electrolyzers that produce hydrogen qualifying as renewable under EU rules.[1][6]

Hydrogen produced at the Cachimayo plant is used to synthesize ammonia, which then serves as the main feedstock for producing ammonium nitrate, a key component of ANFO (ammonium nitrate–fuel oil) explosives widely used in mining.[1][4] Enaex emphasizes that Cachimayo is the only plant in Peru producing ANFO-grade ammonium nitrate and that this ammonium nitrate is a fundamental input for the mining explosives supplied to its clients.[4][7]

The green status of Cachimayo’s hydrogen hinges on electricity supplied under arrangements that certify the energy as renewable, implemented in partnership with Engie.[4][7] This approach relies on power purchase agreements (PPAs) and certification mechanisms that guarantee the origin of the electricity used for electrolysis and plant operations.
