Pumped Hydro Storage
There is much talk these days about energy storage. As more and more wind and solar power enters the electrical grid, there is an increasing need to be able to store excess energy and have it available when the wind isn’t blowing or the sun isn’t shining. Much of the talk centers around battery technology, and having storage batteries distributed throughout the grid is the most versatile and widely applicable way to provide storage.
Storing Energy As Ice
One of the challenges of operating the electricity grid is that there are times when everybody wants more electricity than usual – like during a hot afternoon in August – and the system struggles to keep up with the increased demand.
Artificial Leaf Progress
The Joint Center for Artificial Photosynthesis was established at Caltech and its partner institutions in 2010 with one main goal: to find a cost-effective way to produce fuels using only sunlight, water and carbon dioxide. The natural process of photosynthesis in plants accomplishes exactly the same thing. As a result, such a solar fuel generation system is generally described as an artificial leaf.
