Several electrochemical processes in industry, such as the production of chlorine, produce hydrogen as a “waste” or by- product . This by-product is a very clean A-Grade product that is very well suited for fuel cell vehicles and applications. The scale of these industrial sites is usually very large, resulting in high volumes of hydrogen.
The by product hydrogen can be supplied, either directly to the compressor and the dispenser on-site or through the existing pipeline. The latter is the case at the Solvay plant in Antwerp (Lillo).
