But stability remains a tough challenge. In one recent study, published in Science in April, researchers discovered a new way to build perovskite solar cells with additives that improved efficiency and lifetime. The cells withstood 1,500 hours of high heat and humidity in the lab. The problem is translating these results into the real world. […]
Compressing gases to store energy isn’t new: for decades, a few facilities around the world have been pumping air into huge underground caverns under pressure and then using it to generate electricity in a natural gas power plant. But Energy Dome turned to carbon dioxide because of its physics. Carbon dioxide, when squeezed to high […]
Conductive polymers could wind up being a major player in grid storage, but whether that happens will likely depend on how quickly the company can scale up its technology and, crucially, how much the batteries cost, says Susan Babinec, who leads the energy storage program at Argonne National Lab. Some research points to $20 per […]
Hydropower often comes under fire for its environmental impact, because dams disrupt ecosystems. In fact, California currently doesn’t count large hydropower plants in its renewable-power targets. But regardless of how it’s categorized, hydropower is a lower-emissions alternative to fossil fuels. During high-stress times on the grid, the reduced reliability of hydropower is already causing problems, […]
The measures will mark the first major climate laws in the nation if they pass in something close to their current form. Most notably, they include the Clean Electricity Performance Program, which uses payments and penalties to encourage utilities to boost their share of electricity from carbon-free sources (read our earlier explainer here).
