A University of Colorado Boulder team has developed a radically new technique that uses the power of sunlight to efficiently split water into its components of hydrogen and oxygen, paving the way for the broad use of hydrogen as a clean, green fuel.
A technique for trapping the greenhouse gas carbon dioxide deep underground could at the same be used to release the last fraction of natural gas liquids from ailing reservoirs, thus offsetting some of the environmental impact of burning fossil fuels.
Using a simple solar cell and a photo anode made of a metal oxide, scientists have successfully stored nearly five percent of solar energy chemically in the form of hydrogen. This is a major feat as the design of the solar cell is much simpler than that of the high-efficiency triple-junction cells based on amorphous silicon or expensive III-V semiconductors that are traditionally used for this purpose.
Arctic sea ice is retreating, with projections suggesting that the summer months will be substantially ice-free within the next few years. Nations are waking up to the possibilities for shipping and resource exploration this brings. But for all the potential economic benefits they glimpse, none have taken on board the hidden costs of an Arctic thaw.
The mission of the Fraunhofer Center for Energy Innovation CEI at the University of Connecticut is to develop advanced technologies related to energy storage, fuel cells, in-stream hydro, power management and distribution through contract research.
