The Linde Group and Algenol Biofuels To Cooperate in CO2 and O2 Management for Biofuel Production from Algae

The Linde Group and the US company Algenol Biofuels LLC have agreed to collaborate in a joint development project to identify the optimum management of carbon dioxide (CO2) and oxygen (O2) for Algenol’s algae and photobioreactor technology. (Earlier post.)

This cooperation will see the companies join forces to develop cost-efficient technologies that capture, store, transport and supply CO2 for Algenol’s proprietary process for the production of third-generation (3G) biofuels out of CO2, salt water and algae, as well as remove oxygen from the photobioreactor.

The research collaboration builds on a process developed by Algenol Biofuels and other partners. This method utilizes algae, CO2, salt water and sunlight to directly produce 3G bioethanol and other 3G biofuels or biochemicals in photobioreactors.

Linde has a large body of experience in the cost-efficient supply of CO2 for recycling applications. The OCAP project (organic CO2 for assimilation by plants) in the Netherlands is an example. Here, Linde supplies more than 500 greenhouses covering a total area of 1,500 hectares with CO2 transported by pipeline from a refinery. The higher concentrations of CO2 enable the greenhouse crops to grow much faster. Linde also works with leading energy groups to develop, plan and build pilot facilities for capturing and storing CO2 from power plant processes.



3700 greenhouse acres sounds like a good place for CO2 - many times over.


I like many look forward to the day that the CO2 savings will exceed that generated by the PR machine.

I like the sound of a gases co. sourcing oxygen from biological factories.

There must be people who can put the numbers to low CO2 medium and high (C4) plant use requirements for these " CO2 recycling schemes. Till then I must reserve a judgement.


CO2 for algae and plants is a good idea. Maybe power plants will become integrated energy plants. They will make electricity, produce renewable methane, take advantage of rejected heat and even become food sources for people and fuel sources for transportation.
