But High Hopes is taking a new approach to the problem.Įxisting direct-air-capture tech is expensive to run because of the energy it takes one type of the technology requires heating up the system to more than 1,600 degrees Fahrenheit to release the captured CO2 so it can be stored or used in products. Major companies, from United Airlines to oil giants, are investing in the technology in attempts to address their own carbon footprints. Others followed, including Global Thermostat, a startup that built a giant carbon capture plant in Alabama. In 2017, the Swiss startup Climeworks launched the first commercial plant of its kind, using fans on a rooftop to pull air into a machine where spongelike filters capture carbon dioxide. The startup, an Israel-based company called High Hopes with a German subsidiary, isn’t the first to develop so-called “direct air capture” technology to fight climate change.
