Using seawater and crisp packets to cut CO2 emissions

Reuters have published a short online video:

Using seawater and crisp packets to cut CO2 emissions.

 

The film describes how researchers at the University of York, collect sea water from the nearby  coastal city of Whitby and filter it through a graphite-lined aluminium reactor to trap carbon dioxide. Electricity captured from solar panels is passed through, resulting in the aluminium turning the dissolved carbon dioxide into the mineral dawsonite, a natural component of the Earth’s crust. The process removes the need for high energy gas-pressurisation and toxic chemicals to mineralise the gas. The team also have plans to capture and use the hydrogen, which is generated as a by-product of the process. They see potential for significant scale-up – suggesting that as much as 850 million tonnes of carbon dioxide could be mineralised in this way each year.

 

The underlying research was recently published in the journal ChemSusChem: Capacitance-Assisted Sustainable Electrochemical Carbon Dioxide Mineralisation (Authors: Dr. Katie J. Lamb, Mark R.
