Cement with net zero CO2 emissions.

“While traditional cement production gets its necessary calcium carbonate from limestone that releases carbon dioxide when heated in a kiln, the U-M researchers can make the calcium carbonate through an electrochemical process that captures CO2 from the air and binds […]

Ocean-based carbon capture.

The ocean and air work together to balance the carbon dioxide load. So as the concentration has increased in the air, it has also increased in the ocean. But what if that could work backwards? Planetary Technologies is pursuing the […]

We’re going to need a lot of solar panels.

This will really expand your mind. Casey Handmer makes the case that with the solar costs declining 30% with every doubling of production, an average doubling time of 3 years, and a little more time, we’ll soon see solar energy […]
