MIT team proposes process to recycle lead-acid batteries to fabricate solar cells
August 18, 2014
Researchers at MIT have devised an environmentally-responsible process to recycle materials from discarded automotive lead-acid batteries to fabricate efficient organolead halide perovskite solar cells (PSCs)—a promising new large-scale and cost-competitive photovoltaic technology. The process simultaneously avoids the disposal of toxic battery materials and provide alternative, readily-available lead sources for PSCs.
The system is described in a paper in the RSC journal Energy and Environmental Science, co-authored by professors Angela M. Belcher and Paula T. Hammond, graduate student Po-Yen Chen, and three others.

Critical review finds actual measurement data on segments of natural gas lifecycle sparse or lacking
July 08, 2014
After a critical review of the literature on the air impacts of increased natural gas acquisition, processing, and use, a team of US researchers has determined that that actual measurement data on various individual segments of the natural gas life cycle are sparse or critically lacking.
National and state regulators primarily use generic emission inventories to assess the climate, air quality, and health impacts of natural gas systems. These inventories rely on limited, incomplete, and sometimes outdated emission factors and activity data, based on few measurements, they found. In their paper, published in the ACS journal Environmental Science & Technology, they make a number of recommendations to maximize the benefits and minimize the negative impacts of the natural gas resource.

Ford began production of the North American Transit at Kansas City Assembly Plant on 30 April, and vans will be available in US and Canada this summer. Transit vehicles built in Kansas City are the first to use a new two-wet monocoat paint process developed by Ford and its paint suppliers. The technology results in more durable paint, uses less energy and water, and reduces carbon dioxide and particulate emissions compared with conventional paint processes.
The new paint was subjected to testing simulating typical conditions the vehicle will see over 10 year—e.g., resistance to chipping and scratching, pollutants and sun exposure. Data from preliminary advanced weathering testing indicates that paint applied with the new two-wet technology will retain 90% of its gloss at four years in service compared to 1% gloss retention for paint applied using a conventional monocoat process.

Honda marked the opening of Honda Smart Home US, showcasing technologies that enable zero net energy living and transportation, including Honda’s home energy management system (HEMS), a proprietary hardware and software system that monitors, controls and optimizes electrical generation and consumption throughout the home’s microgrid.
The home, located on the West Village campus of the University of California, Davis, is capable of producing more energy on-site from renewable sources than it consumes annually, including enough energy to power a Honda Fit EV for daily commuting. Honda Smart Home is expected to generate a surplus of 2.6 MWh of electricity over the course of a year, while a comparable home will consume approximately 13.3 MWh. The home’s occupant will be able to use less than half of the energy of a similarly sized new home in the Davis area for heating, cooling and lighting. The home is also three times more water-efficient than a typical US home.

In response to the need to find sustainable alternative sourcing channels for elastomers, the BioButterfly process will make it possible to produce innovative, more environmentally-friendly synthetic rubber. The bio-butadiene produced will support continued innovation in procuring high performance rubber for tires.
JRC study finds 8 metals for low-carbon energy technologies at risk of shortages; EVs, wind and solar, and lighting the applications of most concern
November 04, 2013
A new European Joint Research Centre (JRC) study looking into the supply of raw materials for the manufacture of low-carbon energy technologies found that eight metals were at high risk of shortages. The applications, i.e. technologies, of particular concern as a result are electric vehicles, wind and solar energy, and lighting. The risk arises from EU dependency on imports, growing demand worldwide and geopolitical reasons.
The study builds on a 2011 effort which looked into the six key applications of the Strategic Energy Technology (SET) Plan: wind, solar, nuclear fission, bioenergy, carbon capture and storage (CCS) and the electricity grid. In the new study, these were re-assessed and considered along with 11 other technologies—including fuel cells, electricity storage, electric vehicles and lighting—treated in the new report, this time evaluated on the expected supplies of the metals and not on the current situation as in the first report.

Ford Motor Company has added its near-dry machining process—Minimum Quantity Lubrication (MQL)—to six plants globally, a number that will nearly double in the next few years.
Machining metal pieces generates friction and heat. Conventional wet machining floods the work piece with metal-working fluids, requiring large amounts of fluid to cool and lubricate the cutting tools. MQL eliminates conventional flood coolant from the machining processes, lubricating cutting tools with a fine spray of oil directed exactly when and where it is needed. MQL reduces oil mist generation; biological contamination of coolant; waste water volume; costs for capital equipment; and regulatory permitting. MQL also improves recycling and transport of coolant contaminated chips.
