As California Faces Record Drought Levels, Wind Energy Provides A Vital Service
In 2014, wind energy saved 2.5 billion gallons of water in California by displacing water consumption at the state's fossil-fired power plants, playing a valuable role in alleviating the state's record drought. Wind energy's annual water savings work out to around 65 gallons per person in the state - or the equivalent of 20 billion bottles of water, according to the American Wind Energy Association (AWEA).
According to AWEA, one of wind energy's most overlooked benefits is that it requires virtually no water to produce electricity while almost all other electricity sources evaporate tremendous amounts of water.
In California - where the state is combating record drought levels - Gov. Jerry Brown recently signed an executive order to reduce household water consumption by 25%, from about 140 gallons per day per household to 105 gallons. Wind energy's water savings are, therefore, equivalent to what would be saved by nearly one week's worth of the required reductions for a typical household.
In 2008, U.S. thermal power plants withdrew 22 trillion to 62 trillion gallons of freshwater from rivers, lakes, streams and aquifers and consumed 1 trillion to 2 trillion gallons. By displacing generation from these conventional power plants, U.S. wind energy currently saves around 35 billion gallons of water per year - the equivalent of 120 gallons per person or 285 billion bottles of water.

RESEARCHERS DEVELOP NEW APPROACH THAT COMBINES BIOMASS CONVERSION, SOLAR ENERGY CONVERSION

sunlight to drive chemical reactions to form fuels such as hydrogen, which
provide a way to store solar energy for future use.
RESEARCHERS DEVELOP NEW APPROACH THAT COMBINES BIOMASS CONVERSION, SOLAR ENERGY CONVERSION
In a study published March 9 in Nature Chemistry, University of Wisconsin-Madison chemistry Professor Kyoung-Shin Choi presents a new approach to combine solar energy conversion and biomass conversion, two important research areas for renewable energy.
For decades, scientists have been working to harness the energy from sunlight to drive chemical reactions to form fuels such as hydrogen, which provide a way to store solar energy for future use. Toward this end, many researchers have been working to develop functional, efficient and economical methods to split water into hydrogen, a clean fuel, and oxygen using photoelectrochemical solar cells (PECs). Although splitting water using an electrochemical cell requires an electrical energy input, a PEC can harness solar energy to drive the water-splitting reaction. A PEC requires a significantly reduced electrical energy input or no electrical energy at all.
In a typical hydrogen-producing PEC, water reduction at the cathode (producing hydrogen) is accompanied by water oxidation at the anode (producing oxygen). Although the purpose of the cell is not the production of oxygen, the anode reaction is necessary to complete the circuit.
Unfortunately, the rate of the water oxidation reaction is very slow, which limits the rate of the overall reaction and the efficiency of the solar-to-hydrogen conversion. Therefore, researchers are currently working to develop more efficient catalysts to facilitate the anode reaction.
Choi, along with postdoctoral researcher Hyun Gil Cha, chose to take a completely new approach to solve this problem. They developed a novel PEC setup with a new anode reaction. This anode reaction requires less energy and is faster than water oxidation while producing an industrially important chemical product. The anode reaction they employed in their study is the oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA). HMF is a key intermediate in biomass conversion that can be derived from cellulose - a type of cheap and abundant plant matter. FDCA is an important molecule for the production of polymers.

Stat-X® Condensed Aerosol Fire Suppression
Stat-X® Condensed Aerosol Fire Suppression is a solution for energy storage systems (ESS) and battery energy storage systems (BESS) applications. This includes in-building, containerized, and in-cabinet applications. The Stat-X product was tested for efficacy in putting out Li-ion battery fires. It was found that the Stat-X agent successfully extinguished single and double cell battery fires. This testing was conducted in parallel with a large battery fire testing program. DNV GL Energy conducted the testing and validated effectiveness of the Stat-X aerosol agent on cell level Li-ion battery fires.
