Thanks, I didn't know that.

From "Electrochemical synthesis of ammonia as a potential alternative to the Haber–Bosch process" (2019) :

Water electrolysis, combined with an improved smallerscale Haber–Bosch process, seems to be a short-term solution for the generation of ammonia from renewables at a matching scale. There is a major research focus on reducing the NH3 synthesis reaction pressure and temperature, while keeping the catalyst cost and means to follow the intermittent electrical power input. These technologies are anticipated to be developed within next few years. Electrochemical ammonia production is much more distant from commercialization, however, potential benefits of electrochemical ammonia production, such as reduced energy consumption and associated footprint, scalability, lower process pressures and temperatures, the ability to follow the intermittent electrical power input and use nitrogen with reduced purity justify further research.

From "Electrochemical Synthesis of Ammonia: Progress and Challenges" (2021) :

On the whole, a lot of attempts and significant progress have been made, but the electrochemical synthesis of ammonia is still in the infancy stage with great challenges remained to be addressed.

Toshiba is building them, megawatt-scale, thus far. There is still engineering to be done scaling it up to GW, and it will take a lot of money to get that into volume production for the hundreds of GW-scale plants we will need, but the profits are guaranteed.
