OFFSHORE PRODUCTION OF GREEN HYDROGEN BY ELECTROLYSIS OF SEA WATER ON THE BRAZILIAN COAST

Abstract

The production of Green H2 on a large scale is a challenge for Brazil to play a leading role in this segment. In this article, it is proposed the use of offshore installations for the electrolysis of seawater,using power from wind and hydro-kinetic farms located offshore. The “state of the art” of H2 production in Brazil and in the world was established. The electrolysis processes focused on seawater as an inputwere studied. The potential for generating electricity from renewable sources along the Brazilian coast was surveyed and regions with greater suitability to house the proposed facilities were identified. Offshore installations for the production of Green H2 can place Brazil in a prominent position in the emerging, and very promising, "Green Labeled" H2 market. Therefore, it is imperative that the country immediately initiate incentives and investment in this sector.The production of Green H2 on a large scale is a challenge for Brazil to play a leading role in this segment.  In this article, it is proposed the use of offshore installations for the electrolysis of seawater, using power from wind and hydro-kinetic farms located offshore.
