Ionic Solutions for Carbon Capture – ION Engineering
ION Engineering has developed technology that could be used to economically remove CO2 and other contaminants from fossil fuel power plant emissions and raw natural gas.
According to ION Engineering, until now the state-of-the-art in current emissions control technology was the inefficient, aqueous (water-based) amine technology, but a breakthrough has seen the company become the first to successfully integrate ionic liquid solutions into carbon capture and emissions control technology by replacing the water based solution with ionic liquids – molten salts that do not evaporate. The company says that while recent developments in carbon capture technology have brought costs of carbon capture down to $50 to $100 a ton, its ionic liquid technology could cut the costs of capturing carbon dioxide from coal-fired power plants to as low as $20 a ton. This reduction is cost is mainly due to the fact that around 80% of the total cost of carbon capture and sequestration (CCS) comes from the capture of CO2 – the very area that the company’s system focuses on.
