Improving PEM efficiency - Alejandro Oyarce Barnett of Hystar

January 12, 2023


On this episode of EAH, we sat down with Alejandro Oyarce Barnett, Chief Technology Officer and Co-Founder at Hystar. Hystar is a technology-focused company specializing in PEM electrolysers for hydrogen production using renewable energy. The company got its start as a spin-off from SINTEF, one of Europe’s largest independent research organizations and has raised private funding so the company can focus on production of its high-efficiency PEM units and keep pace with demand for hydrogen generation capacity. Hystar announced on January 11, 2023 that the company has closed a Series B funding round of USD 26mn to rapidly scale-up to full commercial operations with an automated GW-capacity production line by 2025.  Alejandro joined us to discuss in more detail the origins of Hystar, its technology, and the mission at the core of the company.
