Abstract: Researchers in California have produced a cheap plastic capable of removing large amounts of carbon dioxide (CO2) from the air. Down the road, the new material could enable the development of large-scale batteries and even form the basis of "artificial trees" that lower atmospheric concentrations of CO2 in an effort to stave off catastrophic climate change.

Abstract: Electricity is difficult to store on a large scale, making the effort to store sunlight's energy in chemical fuels one of the grand challenges of the 21st century. Today the world consumes power at an average rate of 17.75 trillion watts, 85% of which starts out as fossil fuels, coal, oil, and natural gas. The world's demand for power is expected to at least double by 2050. To keep fossil fuels from stepping in to fill that need, with potentially devastating side effects, any new solar fuels technology will have to provide power just as cheaply, and it must have the potential to work on an equally massive scale. Enter artificial photosynthesis. Researchers around the globe are working to combine materials that capture sunlight with catalysts that can harness solar energy to synthesize fuels, and recent strides are adding new zip to the field.
