Its venture into nuclear fusion and direct air capture stands out, begging the question why it does not focus on cheaper and more accessible ways to cut carbon.

The U.S. Department of Energy will invest $3.5 billion to build four so-called direct air capture facilities. Those plants can arrest CO2 in the atmosphere before burying it or using it to make industrial materials.

MarketWatch’s Rachel Koning Beals joins us to explore some of the best new ideas in climate tech — from large-scale solutions like carbon capture and the next generation of batteries, to the latest in smart thermostats and heat pumps.

Direct air capture snags CO2 from the atmosphere — a small-scale, expensive technology. The rainforests are doing the heavy lifting now.

With a bit of help from the DoE, carbon capture financing is finally taking off in the U.S., with oil and gas giant Occidental unveiling plans to launch a number of DAC plants in the next couple of years.

Tech giant Microsoft is making more moves to address its rising emissions.

The Golden State could have its first regional direct air capture (DAC) hub in the coming years after California Resources Corp. (CRC) subsidiary Carbon

Could fossil fuel companies be forced to remove planet-heating carbon pollution from the atmosphere?

Even under the most aggressive carbon-cutting scenarios, several billion tonnes of CO2 will need to be extracted each year from the atmosphere by 2050, and an accumulated total of hundreds of billions of tonnes by 2100. 

However quickly the world slashes greenhouse gas emissions, it will still need to suck CO2 from the air and oceans to avoid climate catastrophe, a landmark UN report said this week.
