SQM’s solar thermal salts provide clean energy to move towards a green future.

Concentrated solar power (CSP) plants, equipped with a molten salt storage system, store heat during daylight hours and remain operational even in the evening and on cloudy days, significantly increasing their electricity generation. The electricity generated from the thermal storage is fully dispatchable: its power can be connected to the electrical grid at any time.

Niterox® Organic ProAlgae is a high-purity, naturally sourced sodium nitrate. As an essential nitrogen source in standard media such as the Zarrouk recipe, it provides the 16.4% nitrate nitrogen (N-NO₃) that spirulina and other microalgae need for vigorous and healthy growth.
