JFE Holdings Inc., a Japanese engineering company and the country’s second-largest steelmaker, said it developed a cheaper way to separate and capture emissions of carbon dioxide.
Tokyo-based JFE’s method cuts the cost of capturing carbon dioxide to about 2,500 yen ($30) per ton by reducing the amount of energy and pressure needed to convert the gas into a solid hydrate for storage, according to a statement posted on the company’s website today.
The process uses a chemical called Neowhite, which was developed by JFE and Japan’s New Energy and Industrial Technology Development Organization, to make the hydrate form at a higher temperature when cooling, reducing energy costs, the statement said.
JFE plans to research the technique for use at power plants and factories, the statement said.
