Silicon
Silicon is a semi-conductor material that, like all other energy metals, does not exist in its pure state and is incredibly costly to extract. The E.U. considers silicon a critical raw material for its wide-ranging role in modern technologies behind industrial and consumer products.
Silicon demand is estimated to reach 3.8 million tonnes (MT) or US$20 billion by 2025 (CRU Group), with growth primarily driven by demand for chemical-grade silicon (99.5 per cent Si). The silicones product end market is growing at a 10.7-per-cent CAGR and expected to reach US$23 billion by 2025 (Markets and Markets).
Since 1899, the commercial extraction of silicon from quartz has relied on an expensive and energy intensive carbothermic process, meaning the industry is in dire need of disruptive technologies. HPQ Silicon considers itself up to this task.
The conventional carbothermic process produces 98 to 99.5 per cent silicon under the following constraints:
The PUREVAPTM QRR’s production of 99.5-99.99 per cent silicon offers considerable improvements compared to the legacy method:
Scalable by minimum increments of 2,500 tonnes/y
Minimum investment 85-90 per cent less than a conventional plant
4.5 tonnes of feedstock to produce 1 tonne Si
Expected 3N to 4N Si production for less than US$2,000/tonne
3N to 4N+ Si production in one step, allowing HPQ to make material for battery applications for less than its competitors
3N to 4N+ silicon opens up many high-value product lines for HPQ. These include:
Auto and EV manufacturers, who employ metallurgical grade silicon (98.5 per cent Si) to make vehicles lighter and stronger
Its usage as feedstock to make micron-size silicon powders for Li-ion battery applications and silicon nitride, as well as nano silicon powder and nanowires for next-generation Li-ion battery applications
Polysilicon for solar and electronics, an end market growing at a 20-per-cent CAGR expected to surpass US$200 billion by 2026 (Markets and Markets)
2N silicon is also a key feedstock needed for modern technology and to advance the clean energy revolution. Anticipated 2N demand is estimated to generate a 1 MT deficit over the next decade.
