ESG claims 100% CO2 capture rate in new test

ESG Clean Energy, a developer of power generation and carbon capture systems, announced that its carbon capture system had achieved 100% capture from a combustion exhaust stream.

Testing was conducted at the company’s 4.4 MW gas-powered plant in Holyoke, Massachusetts, which serves the local electric grid.

The company called it a "huge milestone" and said it's possible for any internal combustion engine – big or small – to have no CO2 emissions.

ESG’s carbon capture system consists of a two-step process: first removing the water from the exhaust and then capturing the CO2. Drying the exhaust more than doubles a CO2-adsorbent’s capacity, enabling 100% of the carbon to be captured while simultaneously reducing the size and cost of the system.

ESG’s water removal and carbon capture system is designed for both large and small systems and can be retrofitted onto current operating power plants plus applied to mobile applications, the company said.

ESG's water removal system consists of an advanced ceramic membrane incorporated into a mechanical cooling system. According to the company, the CO2 capture system uses solid adsorbers that are nontoxic and easy to handle, making the entire system very versatile and energy efficient.

ESG plans on implementing this technology across all its planned facilities. It has also licensed the technology to a subsidiary of Camber Energy.

The company plans to build a second gas-fired plant in Holyoke. The 4.2 MW plant would also be powered by Caterpillar engines.
