PYROGENESIS ANNOUNCES COMPLETION OF COKE-OVEN GAS VALORIZATION AND HYDROGEN PRODUCTION PROJECT FOR TATA STEEL

PyroGenesis Inc.'s subsidiary, Pyro Green-Gas Inc., has completed the previously announced $9.3-million coke-oven gas valorization (through purification, desulphurization and heavy hydrocarbon removal) and hydrogen production project for Tata Steel, one of the world's largest diversified steel producers.

As outlined in a news release dated May 3, 2023, Pyro Green-Gas was contracted to supply: (i) coke-oven gas purification solutions; and (ii) hydrogen production processes, to extract hydrogen and other toxic gases from the blast furnace process, and then separate, clean and process the gases to render hydrogen to a 99.999-per-cent-purity level. With today's announcement, the project has been completed, and the systems developed by Pyro Green-Gas are in a continuous 24-hour-per-day operation at the Tata steel facility in Kalinganagar, India. The newly reformed hydrogen produced by the system is being reused by other applications at the facility, improving production efficiency and environmental outcomes. The project contributes to Tata's circular production goals, as well as to its cost reduction programs.

"This is a tremendous achievement for our team. The success of this project, which in its totality covers an area the size of a football field and is more than five storeys tall, has led to a number of new initiatives currently under discussion with Tata Steel," said P. Peter Pascali, president and chief executive officer of PyroGenesis. "Our engineers worked closely with Tata Steel to develop a solution to meet the needs of one of the largest steel facilities in the world, including the integration of advanced solutions (such as water-injected compressors that eliminate the potential for oil contamination during the processing of hydrogen) further contributing to sustainability in steelmaking."

Blast furnaces utilize coking coal, or coke, as part of the process to transform iron ore into steel. Coke acts as both a fuel to generate the intense heat required for smelting and as a reducing agent to remove oxygen from the iron ore. The gas released during the coke production process, known as coke-oven gas or COG, is a toxic mix of human carcinogens composed of approximately 54 per cent hydrogen with the balance consisting of methane, carbon monoxide, carbon dioxide, tar, naphthalene and other hydrocarbons which must be separated and removed before the hydrogen can be cleaned, reformed and reused. PyroGenesis's subsidiary Pyro Green-Gas has decades of experience designing and installing technology solutions for these purposes.

"With more than 1,400 blast furnaces in existence across 477 plants in 55 countries and with (as of September, 2023) 70 per cent of planned new global steel projects intending to use blast furnaces, the need for effective COG cleaning and valorization solutions in the steel industry is likely to continue for decades," noted Mr. Pascali. "The systems that we have installed at the Tata Steel Kalinganagar facility are purifying 32,000 cubic metres of coke-oven gas per hour while extracting 620 cubic metres of ready-to-use hydrogen per hour. This represents just a fraction of the potential impact our technologies can have as more steel plants embrace the concept of COG valorization."

PyroGenesis development of coke-oven gas cleaning solutions is part of the company's three-columned solution ecosystem that aligns with economic drivers that are key to global heavy industry. Coke-oven gas cleaning solutions are part of the company's energy transition and emission reduction vertical, where gas cleaning and conversion technologies, and fuel switching to PyroGenesis's electric-powered plasma torches, help heavy industry reduce energy costs, fossil fuel use and emissions. The other verticals are waste remediation and commodity security and optimization.
