Specialists of the Moscow Institute of Power Engineering have created an innovative technology for producing hydrogen from BOF gases, a by-product of metallurgical processes. This discovery, reported by the university's press service, promises a significant reduction in the cost of hydrogen production and a reduction in environmental impact.
The essence of the new technology is to add natural gas to BOF gases, lowering their temperature and producing gas containing hydrogen. This method, based on the zero-waste principle, ensures efficient use of energy and reduces greenhouse gas emissions.
Calculations show that a steel plant producing 10 million tonnes of BOF steel per year can produce up to 92,000 tonnes of hydrogen at a production cost of no more than 7 rubles per cubic metre (about USD 0.076). This could also reduce greenhouse gas emissions by 947 thousand tonnes per year.
A unique feature of the reactor is the use of metallurgical production waste as a temporary catalyst, which is then returned to the technological process.
"This new development can solve two important tasks - reducing the carbon footprint of heavy industry and creating a new, affordable hydrogen production technology," said Nikolay Rogalev, president of the institute.
