Mini carbon-capture plants to slash costs, Mitsubishi Heavy says

TOKYO -- Japanese conglomerate Mitsubishi Heavy Industries is preparing to offer small carbon-capture plants that will slash the costs of cleaning the exhaust of global warming gases by roughly half.

Mitsubishi Heavy is conducting trials of a small-scale facility that can capture 100 tons of carbon dioxide a day. The company plans a commercial model in 2023 that will capture up to 500 tons. The facilities will use common components to keep manufacturing costs down.
