One of the projects, 320,000 tons of green ammonia in production, planning to build a another one with 1,520,000 tons capacity.
The economics aren't quite there yet for Green Ammonia to compete with Chinese coal-based Ammonia although it will get there. Looks like $500 / tonne currently at Chifeng, but dropping to below $400 / tonne by 2028.

If we analyse the 320,000 tonne Envision Phase 1 project, it's going to consume ~3 Billion kWh
If the electricity cost is a very low 2.5c/kWh, that is $75Million
Then the plant costs $1.5 Billion. If we assume financing at 3% for 25 years, that is another $85 Million annually.

So overall, green Ammonia comes to:
Overall Cost = $499 / tonne
-Capital costs = $265/ tonne
-Electricity costs = $234 / tonne
That is significantly more expensive than Ammonia based on Chinese coal ($300-$350).
But it is less expensive the recent price spikes to $500-$600 that we currently see in Europe, the Middle East and North America. But still more expensive than usual Ammonia prices elsewhere. Plus we have transport costs.
