Toronto-based Hydrogen Optimized, a subsidiary of Key DH Technologies, said it has demonstrated the capability of its patent-pending RuggedCell high-current unipolar electrolysis system to ramp from 0 to 50,000 amperes in less than 10 seconds.
“This breakthrough shows that RuggedCell technology can be used to stabilize electrical grids and optimize energy recovery from intermittent renewable power sources such as solar and wind,” the company wrote on Wednesday, referring to its alkaline water electrolyzers.
“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,” commented Hydrogen Optimized CEO Andrew Stuart.
According to the company, the technology is a significant development away from low-current, low-power bipolar alkaline technology in the market. “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.” pv magazine- link - Sergio Matalucci - link - more like this - link
