PARC to Supply Plastic Electronic Methane Sensors for BP
A project for developing low-cost printed electronic gas sensors to monitor the presence of methane has been announced by Xerox’s California-based future technologies division PARC

The System of Printed Hybrid Intelligent Nano-Chemical Sensors (SPHINCS) is receiving public funding from the US Department of Energy (DoE). The DoE is keen to evolve the technology as methane is a potent greenhouse gas.

2013 senate report estimated that in 2011, 69 billion cubic feet (2 million cubic metres) of natural gas were being lost annually from the US’s aging pipeline network. The cost of this was calculated to be over $20 billion.


PARC building cleantech portfolio; co-extrusion printing of novel battery electrodes and carbon-neutral renewable liquid fuels from atmospheric CO2
9 March 2011 | Green Car Congress
by Mike Millikin

"Two of the projects Elrod and PARC were discussing at last week’s ARPA-E Energy Innovation Summit in Washington DC were a technology for the co-extrusion printing of novel battery electrodes, enabling higher energy and/or power densities; and an approach to producing carbon-neutral renewable hydrocarbon fuels using air, water and CO2 captured from the atmosphere.

Electrodes. ...The PARC technology provides a directed-assembly printing method for producing a greater proportion of this 'three-phase boundary' than conventional electrode manufacturing methods—up to 10x the air-breathing surface area of conventional electrodes...

Carbon-neutral liquid fuel. ...In a paper published in the RSC journal Energy & Environmental Science, the PARC researchers present results indicating that the energy consumption required to regenerate CO2 gas from aqueous bicarbonate (carbonate) solutions using this method can be as low as 100 kJ (200 kJ) per mol of CO2 in the small-current-density limit."


Is ARPA-E Enough to Keep the U.S. on the Cutting-Edge of a Clean Energy Revolution?
ARPA-E, the U.S.'s energy transformation agency, is doling out funds for greener power, but is it too conservative?

"...$100 million from the American Recovery and Reinvestment Act of 2009 (better known as the stimulus) was made available on March 2, to be awarded via ARPA–E to the best proposals for new grid-scale storage devices, better power converters and more efficient air conditioners, such as the ones being developed by PARC that rely on sound waves rather than mechanical pistons to drive compressors."

A conference being put on by the new Advanced Research Projects Agency for Energy (ARPA-E) this week is packed with companies exhibiting intriguing approaches to clean energy. I'll be looking into some of them in more detail in upcoming stories, but here's a few that caught my eye.

...PARC, spun out of Xerox PARC, is developing a new form of refrigeration that could be three times as efficient as existing forms. It's based on thermoacoustics, a technology that works for cooling at extremely low temperatures (such as for liquefying gases), but hasn't been used for cooling at room temperature (what you need for household refrigeration). The company thinks it's found a way around previous limits to the technology.


Can Sound Waves Reduce Power Consumption?
PARC says it may have developed a way to run air conditioners on sound waves.

However, that [laboratory thermoacoustic compressor] equipment works best in extreme situations and is not particularly efficient or economical for keeping office buildings at 72 degrees. PARC's breakthrough lay in devising a thermoacoustic device for ambient temperatures...If it works and can go commercial, the cooling sound from PARC could take a substantial chunk of out U.S. and even global power consumption.
