Problems solved by technology

The downside of this technology is that the device only provides the electricity needed to electrolyze water, and at the same time, uses alkaline electrolysis cells, which are less efficient

The disadvantage of this technology is that it needs to separately provide the electric energy required for the SOEC electrolysis process. At the same time, the solar energy needs to be collected to a high temperature of 1000°C, and then transferred to the hydrogen production module through a heat exchanger. Utilization is indirect utilization, and the energy loss in the intermediate heat exchange process is large, which will lead to low solar energy utilization efficiency
