HYDROGEN PRODUCTION
Efficiency and safety in the production of green hydrogen.
Cooling electrolyzers is essential to maintain effi ciency and safety in hydrogen production. It uses thermal control systems to dissipate the heat generated during electrolysis, optimizing performance and prolonging the useful life of the equipment. Advanced strategies include liquid cooling and intelligent temperature management.

GREEN HYDROGEN REFRIGERATION
HYDROGEN PURIFICATION
After the electrolysis process, the hydrogen stream contains traces of water that must be eliminated to meet the standards specifi ed in ISO14687 for use in fuel cells, in whose applications purity levels of up to 99.999 % are required. This purifi cation is achieved through a Pressure Swing Absorption process (PSA). Prior to this process, a significant amount of moisture can be extracted by cooling the hydrogen, avoiding negative temperatures to prevent formation of ice.

COMPRESSOR COOLING
Refrigeration in hydrogen compressors is essential to manage the heat generated during compression, maintaining operational effi ciency and safety. Specialized cooling systems, such as chiller plants with negative temperature secondary fl uids, help control temperature, reducing risk and extending equipment life. This approach ensures a constant and safe supply of compressed hydrogen.
HYDROGEN DISPENSERS
When refueling the vehicle, the pressure in the tank increases, also causing an increase in temperature. This heating can cause thermal degradation of the tank, which is why regulations such as ISO 19880 and SAE J2601 limit the maximum temperature. To avoid reaching these temperatures, there are two options:
- Slow fueling: heat caused by pressure increase dissipates through the tank structure. This is only possible for heavy vehicles (H35) and requires very long fi lling times.
- Hydrogen pre-cooling: It is chosen to cool the hydrogen in the temperature range between -10 ºC and -40 ºC, depending on the application, with the aim of guaranteeing safe and fast refueling.
