Electrochemical acceleration of chemical weathering for carbon capture and sequestration

Carbon dioxide capture and sequestration

Carbon Capture and Sequestration (CCS)

Carbon capture and sequestration (or storage)—known as CCS—has attracted interest as a measure for mitigating global climate change because large amounts of carbon dioxide (CO 2) emitted from fossil fuel use in the United States are potentially available to be captured and stored underground or prevented from reaching the atmosphere. Large, industrial sources of CO 2 , such as electricity-gener...

What future for carbon capture and sequestration?

Amid the dire warnings of severe weather perturbations and globally rising temperatures, scientists, engineers, policy makers, and others are searching for ways to reduce the growing threat of climate change. There is no single solution, but the development of carbon capture and sequestration technologies, which has accelerated greatly in the last decade, may play an important role in addressin...

Electrochemical acceleration of chemical weathering as an energetically feasible approach to mitigating anthropogenic climate change.

We describe an approach to CO2 capture and storage from the atmosphere that involves enhancing the solubility of CO2 in the ocean by a process equivalent to the natural silicate weathering reaction. HCl is electrochemically removed from the ocean and neutralized through reaction with silicate rocks. The increase in ocean alkalinity resulting from the removal of HCI causes atmospheric CO2 to dis...
