Bright to build CO2 liquefaction plant in the US

By | 2022-08-25

Bright Renewables has been awarded a contract for the realization of a turnkey CO2 liquefaction plant with a capacity of 800 kg per hour on the West Coast of the United States of America. The CO2 liquefier will be added to an existing biogas upgrader and will purify and liquefy carbon dioxide coming from the biogas upgrader. Liquid bio-CO2 is the end-product, which will be applied in the company’s industrial processes resulting in greater independency on CO2 derived from natural gas.

“There is an ever-increasing market demand for small scale liquid CO2 production facilities. CO2 consumers are looking for more independency of large producers and biogas producers are looking to reduce their CO2 emissions. We are happy to have grown into a technology provider with biogas upgrading, and cryogenic technologies, including CO2 liquefaction and bio-LNG, and carbon capture technology in our portfolio. This allows Bright to contribute to global CO2-reductions in various ways”, says Jafeth Bulsink, Business Developer at Bright. Bright has realized over 25 biogas upgrading projects with membrane technology in the US and nearly 200 projects worldwide. 

Clean CO2 liquefaction technology 

A Bright CO2 liquefaction plant, with in-house developed CO2 liquefaction technology, is a prefab compact containerized technology based on an in-house developed cryogenic process with clean circular cooling. Liquefaction reduces the methane slip during biogas upgrading and enables an additional revenue stream by producing liquid (bio)-CO2 for among others the horticulture-, food- and refrigeration-industry. Jafeth Bulsink: “Currently, our technology is particularly interesting for biogas production facilities from 500 SCFM (800 Nm3/hr) biogas production, but we continue to develop the technology to be beneficial for even smaller scales”.

Low CI Score 

In several states in the US, a low carbon fuel standard has been established in which the carbon intensity (CI) score is of importance. The score, the lower the better, is used to measure all greenhouse gas emissions associated with the production, distribution and consumption of a fuel. A CO2 liquefaction plant as add-on technology to a biogas plant with biogas upgrading technology, may lower the CI score.
