Development of Fully Renewable Biomass PET Polymer

July 12, 2011 · Filed Under Clean Tech, Green Tech · Comments Off on Development of Fully Renewable Biomass PET Polymer 

In a joint effort by Toray Industry of Japan and Gevo of U.S, the company’s have successfully developed a fully renewable biomass based Polyethylene Tetraphthalate (PET) Polymer. Geno’s share of effort in developing this fully renewable PET was in converting isobutanol, which was produced from biomass using genetically modified microorganisms to para-xylene through use of conventional chemical process. To complete the development of this Biomass driven PET, Toray applied a new technology and PET polymerization as well as film production technology to terephthalic acid which was synthesized from Gevo’s biomass driven para-xylene and commercially available and renewable mono ethylene glycol (MEG) as raw materials.

Development of Smart Grid Technology for Reducing Power Loss in Solar Panels through Detection of Malfunctions in Panels by AIST

August 19, 2010 · Filed Under Green Tech · 1 Comment 

Cost and efficiency are two formidable stumbling blocks in proliferation of solar power generation system, an important step for promoting the use of renewable energy and realization of low carbon society. A normal solar panel is estimated to have a life span of around 20 years; however it is very difficult to prevent failures in a solar panel during its entire life cycle. Once a solar panel generation system is installed, it generally not inspected, making it difficult to identify a defective panel even there is a fall in the output of photovoltaic system, and therefore the system is not fully utilized. Now, to overcome this issue, a group researchers at AIST have come up with a cost effective way of monitoring the health of each panel through development of communication technology which utilizes the direct current (DC) power line of a solar panel as a communication line. The new technology monitors the power generation in each solar panel and prompt detection of malfunctions in the panel. Read more
