Linde, in collaboration with Sapphire Energy, will reduce the costs associated with the delivery of anthropogenic CO2 for commercial-scale open pond algae cultivation.

Linde will also supply all of the CO2 to Sapphire’s commercial demonstration facility in New Mexico, US.

Sapphire said the company has developed a proprietary technology along the entire algae-to-energy value chain from biology, cultivation, harvest and extraction, to refining, resulting in a highly scalable process to produce a renewable and low carbon substitute for fossil-based crude oil.

Sapphire’s technology represents an approximate 70% reduction in lifecycle carbon emissions compared to petroleum-based equivalents.
