Researchers come up with carbon-neutral way to store excess energy as methane

One of the major drawbacks to renewable energy sources like wind and solar is that we don't have an effective way to store excess energy. When the wind blows, we might have more than enough energy to feed the grid, but we can't store the surplus. Then, on breezeless days, we're left powerless. As Read More...

Cement is a huge polluter. Here’s how the industry is tackling the problem

While cement is incredibly versatile, the relatively cheap building material comes with a huge downside: it’s a massive greenhouse gas emitter. In fact, it’s responsible for about 8 percent of the world’s carbon dioxide emissions. If the cement industry were a country, it would be the Read More...

Carbon capture firm receives $

Carbon capture firm receives $68 million funding to commercialize its tech

Carbon capture technology is poised to be a vital tool in the global fight against climate change. The only problem is high costs and a limited commercial market makes scaling it up a rather slow process. Recently, however, that trend seems to be changing. Take, for example, a Canadian company Read More...
