Ecopetrol, a state-owned company in Colombia, is embarking on a green hydrogen initiative at its Reficar refinery in Cartagena. The proposed plant, requiring a $28.5 million investment, will utilize proton exchange membrane (PEM) electrolyzer technology to produce 800 tonnes/year of low-carbon green hydrogen. This project aligns with Ecopetrol's commitment to achieving carbon neutrality by 2050, following the completion of a pilot testing for sustainable aviation fuel (SAF) production at the refinery. Ecopetrol's sustainability efforts also include Latin America's first solar farm within a refinery, aiming to reduce carbon dioxide emissions by 21,000 tonnes/year. Additionally, the Cartagena refinery is exploring various environmental initiatives, such as carbon capture, water neutrality, renewable diesel production, plastic processing, and potential petrochemical production using hydrogen. These endeavors demonstrate Ecopetrol's dedication to innovation, sustainability, and environmental stewardship in transforming refinery operations.
