We have entered R&D grid-independent hydrogen production tech since the end of 2019 by customer inquiry. One of our customers in Iowa wants to use wind power to produce hydrogen directly disconnected from the grid. We searched all suppliers of electrolyzers globally. But it failed, and then we started to research grid-independent hydrogen production tech. This tech was proved by a small prototype with 14 electrodes. We have invested in hydrogen production $300,000 and have applied 5 patents, including PCT. The core tech is that each electrode can be controlled by cutting in/cutting off in series, connecting according to the power changing from wind/solar in the electrolyzer. Each electrolyzer can be controlled by cutting in/cutting off in parallel, connecting according to the power changing from wind/solar power in the hydrogen production station. It merged wind& solar power technologies into electrolysis technology. It is a kind of algorithm method and electronic control technology. It is regardless of the capacity of the electrolysis system.
