AN059 – Hydrogen stacks directly fed in DC from solar panels and batteries.

AN059 explains the different options for an electrolyzer to be fed in DC from solar panels and/or batteries. This supply needs also to ensure the operation of the stack even in the event of sudden power changes.

To produce green Hydrogen, it is mandatory that the electrolysis uses energy obtained from renewable sources. The H2 obtained would be a green vector of energy that could contribute to decarbonisation of related industrial processes.

Along with the use of modular bidirectional DC/DC converters with MPPT functions, it’s possible to create efficient, resilient, and power optimized solutions. DC/DC converters are power electronic components with similar technology to DC/AC inverters. They are generally used in the battery and solar panel sector.
