To control expenses, many plants that use hydrogen atmosphere in their heat treating process are looking closely at controlling the cost of industrial hydrogen. One option is using on-site hydrogen generation.
Many factors contribute to the cost of hydrogen in heat treatment, and many of them are controllable. Of particular interest are the costs associated with delivery, including trailer leasing, transport costs, hazardous materials fees, and others. Combined, these costs can constitute up to 55% of the cost of hydrogen.
On-site hydrogen generation offers the potential to dramatically alter the cost picture by reducing or eliminating transport costs. Several on-site hydrogen generation technologies are currently available, and the challenge is to optimize these systems to maximize cost savings.
