This breakthrough shows that the company’s electrolysis system can be used to stabilize electrical grids and optimize energy recovery from intermittent renewable power sources such as solar and wind.
The system’s rapid power load response rate contrasts sharply with low-current, low-power bipolar alkaline technology in the marketplace today. These systems are inherently limited in their range of power variability and take several minutes or more to ramp up and down. Furthermore, like PEM technology, individual bipolar alkaline modules are limited to smaller-scale output.
Designed to meet the needs of large hydrogen applications
The RuggedCell™ electrolyser as demonstrated is believed to be the largest water electrolysis cell in the world today. The technology is designed to meet the needs of the largest green hydrogen applications. Its capacity to rapidly shift hydrogen production rates in response to variations in the available power is vital to wind and solar power generation equipment providers, renewable power system designers and operators, renewable hydrogen project developers, and end users of green hydrogen.
Andrew Stuart, President and CEO of Hydrogen Optimized, said: “To this point, the consensus among green hydrogen experts worldwide has been that only PEM water electrolysers could rapidly absorb and shed electricity and thereby be used to stabilize variable electric power sources. We have now proven that RuggedCell™ alkaline technology, which is uniquely scalable to individual system deployments in the hundreds of megawatts, equals or betters PEM technology’s capability to handle variable power levels.”
