Saint-Gobain’s Advanced Silicon Carbide Pipes for Thermal Cracking Technology
Advanced thermal cracking technology transforms a wide range of non-recyclable and hazardous wastes into a clean synthesis gas (syngas) and biochar. As it doesn’t burn waste, the process has very low emissions. Tar-free, the syngas of company Standard Gas/GB, achieved the End of Waste certification from the GB’s Environment Agency. It can be used to generate electricity, and heat, or processed via methanation into transportation fuels, chemical feedstock or for grid injection. Coupled with electrolysis or via reformation, the SG100 can generate between 650–3000 t of green hydrogen a year. The co-product biochar captures and removes carbon when used in sequestering applications such as soil conditioning or as an aggregate for construction materials such as concrete and asphalt.
Saint-Gobain’s/FR advanced silicon carbide pipes are ideal for this process and have higher heat resistance than steel and metal alloy alternatives. After approval the commercial-scale demonstration plant in Cambridgeshire/GB, the scaled-up plant is under construction. Capable of processing 48 000 t of waste a year, the SG100 can generate an average of 40 000 MWh of power and, dependent on feedstock, remove up to 16 000 t of CO2. With a small footprint, the plant can be deployed in a modular manner, making it rapidly scalable for a range of end-use applications.
