solid oxide electrolysis cells
”The first 100 MW of cells to roll off the assembly line are headed to coastal Texas, where Topsoe customer First Ammonia is building a plant slated to make 300 metric tons (t) per day of green ammonia from electrolytic hydrogen generated with renewable electricity. The plant, set to begin construction early next year, will use an ammonia synthesis system also supplied by Topsoe.”
300 mt/day is tiny. Commercial plants are 5 or more times larger.
