The PUREVAP™ QRR process reduces GHG emissions significantly disrupting GHG impact of solar manufacturing
From mining and manufacturing the components to delivery and construction, solar energy makes its small (but growing) contribution to the world’s carbon budget. Within the process of creating solar energy plants, the production of the solar grade silicon (SoG-Si) used in the manufacture of cells and modules, which must be refined to a purity of 99.999% or better, is the most energy-intensive part of the process.
In China, where most of the world’s solar panels are currently produced, the manufacture of SoG Si generates around 141 kg of CO2 per kg of SoG Si. In Germany, the same processes applied using less carbon-intensive electricity sources, generate only around 87 Kg of CO2 per kg of SoG Si.
By manufacturing SoG Si in Quebec, where electricity has a low carbon intensity, and using the efficient PUREVAP™ QRR Process, a new proprietary (patent pending) carbothermic process, we expect to generate a mere 5.4 Kg of CO2 per kg of SoG Si – a fraction of what other manufacturing processes are generating.
