The Future is Electric

Reinforced concrete holds up our world, but in addition to the cement, steel reinforcement comes with a big carbon debt

Blocks, sand, viscous liquids, water towers and the like are only good for moving money between pockets, not storing energy

What is available locally is what is used in construction, be it blast furnace slag, sand or old volcanoes

Geopolymers turn high-volume industrial wastes like those from the aluminum process into a cement replacement

Geomechanical subsurface pumped hydro startup fails basic rule of fracking: only do it once per underground volume

As I explore cement and concrete decarbonization, people in the know graciously (mostly) steer me in the right direction

It could scale to displace Portland cement, but will it work, be lower carbon and economically viable?

Mining aggregate for concrete is one of the biggest industries on the planet, and it’s powered by diesel today

Supplementary cementitious materials are widely used already so aren’t as much of a lever as many think
