Harvard University Research on Green Energy Storage Batteries




Green Energy sources like wind and solar do not always produce power in the same cycle as needed by users.  That is, the wind might blow at night not during work hours … so an effective “green energy storage” system could really make green energy sources more useful.  “Green energy storage” needs to be relatively cheap or the green energy is not cost effective.

Harvard is conducting research on a “flow battery” that might provide “ …  cost-effective, grid-scale electrical energy storage based on eco-friendly small organic molecules …..  “Flow batteries may make stationary storage viable in the marketplace, and that will enable wind and solar to displace a lot more fossil fuel.”

Flow batteries are like a rechargeable fuel cell using liquid chemicals to store generated  power.  Current technology uses vanadium redox (cost prohibitive due to raw material prices) or molten sulfur (must operate at very high temperatures).

Harvard’s research is looking at small organic molecules that are found in plans and can be made at low cost, are non-toxic and work room temperatures. These would offer high power density and could be co-located with the generating power source and would link directly to the power grid.

The investment for production facilities is projected as low as $10 million to $15 million per 100-megawatt to 150-megawatt production capability, as compared with current costs of as much as $250 million for standard solar-cell production facilities.

Vanguard’s production equipment would be designed for insertion into an existing roll-to-roll film-coating line of the sort that has been displaced by the emergence of digital photography.

Cylindrical Solar Rooftop




Solyndra targets commercial rooftop market with new solar photovoltaic (PV) system that uses a cylinder shape to generate significantly more solar power. ...
... "Solyndra's panels employ cylindrical modules which capture sunlight across a 360-degree photovoltaic surface capable of converting direct, diffuse and reflected sunlight into electricity. This self-tracking design allows Solyndra's PV systems to capture significantly more sunlight than traditional flat-surfaced solar panels, which require costly tilted mounting devices to improve the capture of direct light, offer poor collection of diffuse light and fail to collect reflected light from rooftops or other installation surfaces. Conventional flat PV panels must be mounted at an angle and spaced apart for optimum energy production. The sunlight striking the spaces between the panels is not collected and thus is wasted. Solyndra's panels perform optimally when mounted horizontally and packed closely together, thereby covering significantly more of the available roof area and producing more electricity per rooftop on an annual basis than a conventional panel installation.

Solar cells built using IMM technology recently achieved world record conversion efficiency of 33% used in space, and it is anticipated that efficiency levels in the 42%-45% range will be achieved when adapted for use under the 500-1500X concentrated illumination, typical in terrestrial concentrator photovoltaic (CPV) systems. Once commercialized, the CPV systems that are powered with EMCORE's IMM based products will see a reduction in the cost of power generated by approximately 10% to 20%. EMCORE expects to commercialize this technology for both space and terrestrial applications in 2009. Developed in conjunction with the National Renewable Energy Laboratory (NREL) and the Vehicle Systems Directorate of the US Air Force Research Laboratory (AFRL), the IMM design is comprised of a novel combination of compound semiconductors that enables a superior response to the solar spectrum as compared to conventional multi-junction architecture. Due to its unique design, the IMM cell is approximately one fifteenth the thickness of the conventional multi-junction solar cell and will enable a new class of extremely lightweight, high-efficiency, and flexible solar arrays for space applications.

... "Through this new reclamation process IBM is now able to more efficiently remove the intellectual property from the wafer surface, making these wafers available either for reuse in internal manufacturing calibration as monitor wafers or for sale to the solar cell industry, which must meet a growing demand for the same silicon material to produce photovoltaic cells for solar panels. When monitors wafers reach end of life they are sold to the solar industry. Depending on how a specific solar cell manufacturer chooses to process a batch of reclaimed wafers - they could save between 30 - 90% of the energy that they would have needed if they'd used a new silicon material source. These estimated energy savings translate into an overall reduction of the carbon footprint for both the Semiconductor and Solar industries. " ...

BIPV Solar Case Study in New York City




Terra Solar's building-integrated photovoltaics case study showcases the Conde Nast Building at 4 Times Square in New York City, where BIPV panels are integrated into the construction. ...
... "In a curtain-wall construction method, custom-manufactured thin-film photovoltaic panels replace mirror glass spandrels from the 37th to 43rd floors on the south and east faces of the tower. The modules were triple laminated for additional strength and cut to size to integrate seamlessly into the building’s original design. " ...
