Está ficando mais barato filtrar o dióxido de carbono do ar – The

The next generation of industrial plants to filter CO2 out of the air is on the way, and it’s getting closer to overcoming some of the biggest challenges of using this technology to fight climate change. Climeworks, one of the first startups to develop this tech, unveiled its Generation 3 plant today. It’s supposed to use half as much energy as older designs and slash costs in half, too.

If Climeworks makes good on that promise, it could go a long way toward making this technology, called direct air capture (DAC), a viable way to reduce the amount of carbon pollution building up in the atmosphere. Right now, the technology is far too new and expensive to make a meaningful dent in those emissions. Nevertheless, a slew of big brands and the Biden administration are already placing a lot of faith — and funding — in developing the technology.

To date, there are about a couple dozen direct air capture plants around the world capable of drawing down about 0.01 million metric tons of CO2 cumulatively per year. Climeworks already provides this service to Microsoft, Stripe, Shopify , BCG, and JPMorgan Chase, among others. But it’s a minuscule amount considering Microsoft alone released more than 15 million metric tons of planet-heating carbon dioxide last year.

• Próxima geração de plantas industriais para filtrar CO2 do ar está chegando;.
• Tecnologia de captura direta do ar (DAC) está sendo desenvolvida para combater o aquecimento global;
• Apesar dos desafios, grandes marcas e governos estão investindo na tecnologia.
