WebHydrogen production today is primarily based on fossil fuel technologies, with over a sixth of the global hydrogen supply coming from “by-product” hydrogen, mainly from facilities and processes in the petrochemical industry. Low-emission production represented less than 1% of total hydrogen production over the last three years. Webplant concepts for hydrogen production. Results of preliminary plant control and stability studies are described. A combination of inventory control in the VHTR plant and flow control in the HTSE plant proved effective for maintaining hot-side temperatures near constant during quasi-static change in hydrogen production rate.

WebThe pretreatment steps in hydrogen production method inhibit methanogenic bacterial activity and hence, the hydrogen consumption decreases and the yield increases. Biological hydrogen production processes are more ecofriendly when compared with other thermo and electrochemical processes (Das and Veziroǧlu, 2001).
