The Race to Reinvent Cement

EXCERPT: [Richard] Courland estimates there is about 40,000 kilograms of concrete for each person alive, and we’re adding about 500 kilograms per person each year. Vaclav Smil, author of Making the Modern World, estimates that China poured more concrete between 2011 and 2013 than the US had done in all of the twentieth century.

Everything about concrete is huge—including its carbon footprint. It’s fair to say that without concrete, the modern world wouldn’t exist. Ironically, it’s also fair to say that, in an unexpected way, concrete is contributing to the destruction of the modern world. That’s because the chemistry of cement, which is the glue that holds concrete together, produces carbon dioxide as a major byproduct. According to a 2018 study, the cement industry is responsible for about 4 percent of global annual greenhouse-gas emissions, nearly twice that of the aviation industry.

That’s why the world’s most common material is urgently in need of an upgrade. Even if we manage to burn fewer fossil fuels, deploy massive solar- and wind-power installations, and transition to electric cars, it won’t be enough to make our emissions goals. For the world to hit net-zero emissions within the next few decades, we will also need to find ways to pull CO 2 out of the atmosphere. And one way to do that would be to store it in our ever-expanding built environment. In fact, concrete could be a remarkably efficient carbon sponge.

Fortunately, work on that upgrade has already begun. Over the past year, while working on a series about solutions to climate change, I stumbled across fascinating developments under way in the cement industry, where both large multinationals and small startups are racing to create a greener product. Some of these companies have already created zero-emissions cement, and others are looking to create “negative emissions” products that would suck carbon dioxide from the air....

I'm paraphrasing but someone once said 'if we could make money at Peace, then the world would be at Peace.' Same goes for 'global warming' busting technology. It just happens to be something I'm invested in. The technology is improving everyday and the cost of implementation is dropping like a stone. It's going to happen in my mind, sooner not later. I got in cheap years ago but the price of investment is going up and my advice is get in now, be patient, and it will eventually pay off. Choose wisely my friends, there are many companies involved, all trying to make a buck. I chose companies that were receiving government grants to pursue their technology, not saying you have to do the same.

That didn't work out for Solyndra.

Stock market not for everybody. Due diligence counts my friend, listening to me does not.
