Carbon-free ammonia production

Craig Baartman, VP Manufacturing - Starfire Energy

"We started using Enapter's EL series of electrolyzers three years ago. They were the best combination of price and performance for the small-scale prototype ammonia system we were building then. As our needs have grown, Enapter's capabilities have been growing too. We are excited to see how they are integrating their electrolyzer stack into their new Multicore 1 MW modular electrolyzer offering. We believe that the future of energy is modular, and we are glad to see Enapter moving down that road."
