A ground-breaking carbon capture project, sequestration and utilisation (CCSU) project, which is believed to be the first of its kind, will capture carbon dioxide (CO2) at a third of the cost typically seen in the global power sector.

Launched by Carbon Clean Solutions Limited (CCSL), the initiative will capture and reuse more than 60,000 tonnes of CO2 each year from a 10 MW coal-fired power station near Chennai in India.

The privately financed project will capture CO2 at $30 per tonne – compared to usual capture costs which reach between $60-90 per tonne. Post-start up, the plant is expected to become zero-emission.

CCSL’s CEO Aniruddha Sharma emphasised, “This project is a game-changer. By capturing and crucially, re-using, CO2 at just $30 a tonne, we believe that there is an opportunity to dramatically accelerate uptake of CCU technology, with its many benefits, around the world.”

“This is a project that doesn’t rely on government funding or subsidies – it just makes great business sense.”

Indian firm Tuticorin Alkali Chemicals & Fertilizers will reuse the CO2 for soda ash production.

Breakthrough

This latest project follows news of the Mumbai-based organisation’s breakthrough test results from its successful pilot campaign carried out at Technology Centre Mongstad (TCM) situated in Norway in May this year.

The trial, carried out from November 2015 to March 2016, involved a drop-in solvent test using CCSL’s patented ‘APBS,’ which involves capturing CO2 using a re-generable solvent combined with a unique heat coupling method.

During the test, which was designed to measure environmental emissions, corrosion and energy efficiency, CCSL successfully captured more than 25,000 tonnes of CO2 with plant availability levels reaching the maximum 100%.
