New Lithium-Based Battery Design Makes Use of Greenhouse Gas

New lithium-based battery could make use of greenhouse gas before it ever gets into the atmosphere.

A new type of battery developed by researchers at MIT could be made partly from carbon dioxide captured from power plants. Rather than attempting to convert carbon dioxide to specialized chemicals using metal catalysts, which is currently highly challenging, this battery could continuously convert carbon dioxide into a solid mineral carbonate as it discharges.

DOE launches initiative to harvest rare earth elements from coal ash

The Department of Energy Fossil Energy’s National Energy Technology Laboratory (NETL) is launching an initiative to harvest rare earth elements (REEs) from coal ash.

Rare earth elements have significant value as they are used in high-technology products such as catalysts, cell phones, hard drives, hybrid engines, lasers, magnets, medical devices, televisions, among others.

Moniz group launches 'substantial' CO2 air capture project

A think tank led by former Energy Secretary Ernest Moniz announced today it is developing a federal plan to promote technologies for removing carbon dioxide from the atmosphere.

The Energy Futures Initiative's air-capture project aims to bring new focus and dollars to an idea that proponents say is necessary to hit long-term climate targets.

Maybe we can afford to suck CO2 out of the sky after all

While avoiding the worst dangers of climate change will likely require sucking carbon dioxide out of the sky, prominent scientists have long dismissed such technologies as far too expensive.

But a detailed new analysis published today in the journal Joule finds that direct air capture may be practical after all.

How Oman’s Rocks Could Help Save the Planet

The rocks here in Oman are special, this scientist says. They remove planet-warming carbon dioxide from the air and turn it to stone. In theory, these rocks could store hundreds of years of human emissions of CO2. Storing even a fraction of that would not be easy. But it’s not impossible.
