Linde, Sapphire unveil CO2 algae-to-fuel deal
German industrial gas giant Linde and US company Sapphire Energy unveiled Wednesday a cooperation project in the production of algae-to-fuel systems.
Linde has undertaken to deliver carbon dioxide "to commercial-scale, open-pond, algae-to-fuel cultivation systems" operated by Sapphire, a statement said.
The German group will also provide CO2 for a commercial demonstration site run by Sapphire in Columbus, New Mexico, it added.
Sapphire has developed a system that produces "a renewable and low carbon substitute for fossile-based crude oil" from algae, the statement said.
Company president Cynthia Warner was quoted as saying that "to produce algal oil, or 'green crude' at the scale to meet growing demand, we need great partners who can supply sufficient and low cost access to CO2."
Linde executive board member Aldo Belloni stressed meanwhile that "producing fuel by algae using CO2 from large emitters like power stations and chemical plants is a very promising way of reducing greenhouse gas emissions."
Facilities that make commercial algae fuel need an estimated 10,000 tonnes of CO2 per day, roughly 30 percent of the current merchant market for CO2 in the United States, the statement said.
Linde has begun to focus on renewable energies and CO2 recycling to fuel growth in the future.
