Waiving the right to remain silent, (M.A. Stewart)

" Most of the hydrogen produced today is consumed on site, such as at an oil refinery, and is not sold on the market. From large-scale production, hydrogen costs $0.32/lb if it is consumed on site. When hydrogen is sold on the market, the cost of liquefying the hydrogen and transporting it to the user must be added to the production cost. This can increase the selling price to $1.00 - 1.40/lb for delivered liquid hydrogen. Some users who require relatively small amounts of very pure hydrogen (such as the electronics industry) may use electrolyzers to produce high-purity hydrogen at their facilities. The cost of this hydrogen, which depends on the cost of the electricity used to split the water, is typically $1.00 - $2.00/lb."
