Fast-Charging Super-Capacitor Technology Unveiled for Clean Energy Storage

Posted by in categories: solar power, sustainability, transportation

Experts from the University of Surrey believe their dream of clean energy storage is a step closer after they unveiled their ground-breaking super-capacitor technology that is able to store and deliver electricity at high power rates, particularly for mobile applications.

In a paper published by the journal Energy and Environmental Materials, researchers from Surrey’s Advanced Technology Institute (ATI) revealed their new technology which has the potential to revolutionize energy use in electric vehicles and reduce renewable based energy loss in the national grid. The team also believe their technology can help push forward the advancement of wind, wave, and solar energy by smoothing out the intermittent nature of the energy sources.

The ATI’s super-capacitor technology is based on a material called Polyaniline (PANI), which stores energy through a mechanism known as “pseudocapacitance.” This cheap polymer material is conductive and can be used as the electrode in a super-capacitor device. The electrode stores charge by trapping ions within the electrode. It does this by exchanging electrons with the ion, which “dopes” the material.

Toward artificial photosynthesis

Posted by in categories: solar power, sustainability

The creation of a fully artificial living cell would signify progress in both understanding current life and the development of synthetic organisms. A crucial component of any living organism is energy generation: the means to power its internal machinery. Because of their relative simplicity, catabolic reactions are the classical means for providing carbon and energy to synthetic cells, and much work has been done in optimizing which energy substrates work best for particular reactions ([ 1 ][1]). Despite robust success using small-molecule energy sources, the possibility of designing anabolic mechanisms that can harvest virtually limitless energy from light is very alluring yet remains unrealized.

This Solar Panel-Like Device Can Generate Electricity in the Dark

Posted by in categories: solar power, sustainability

But a new invention could allow us to continue generating renewable energy even in the dark, the New York Times reports. Electrical engineer Aaswath Raman, at the University of California in LA, has come up with a device that can harness energy from a dark night sky to power an LED — hinting at a new frontier in renewable energy.

Power of the Dark Side

Raman’s findings were published in the journal Joule today. His device — made from easy-to-find materials including Styrofoam and off-the-shelf aluminum parts — takes advantage of radiative cooling, the process that allows objects to release heat after the Sun sets.

Research: A solar window will soon do the same job as a standard rooftop solar panel

Posted by in categories: solar power, sustainability

Semi-transparent solar cells that can be incorporated into window glass are a “game-changer” that could transform architecture, urban planning and electricity generation, Australian scientists say in a paper in Nano Energy.

The researchers—led by Professor Jacek Jasieniak from the ARC Centre of Excellence in Exciton Science (Exciton Science) and Monash University—have succeeded in producing next-gen perovskite solar cells that generate electricity while allowing light to pass through. They are now investigating how the new technology could be built into commercial products with Viridian Glass, Australia’s largest glass manufacturer.

This technology will transform windows into active power generators, potentially revolutionizing . Two square meters of solar , the researchers say, will generate about as much electricity as a standard rooftop solar panel.

A new dimension for solar energy

Posted by in categories: solar power, sustainability

Circa 2012 Now, a team of MIT researchers has come up with a very different approach: building cubes or towers that extend the solar cells upward in three-dimensional configurations. Amazingly, the results from the structures they’ve tested show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.

Innovative 3D designs from an MIT team can more than double the solar power generated from a given area.

Sunflower: Kansas’ largest solar farm begins operation

Posted by in categories: solar power, sustainability

Sunflower Electric Power Corp.

JOHNSON CITY – Sunflower Electric Power Corp. and Lightsource BP have announced that the Johnson Corner Solar Project entered commercial operation on April 7. The $37 million project, which was financed and constructed by Lightsource BP, is located approximately 2 miles southwest of Johnson City in Stanton County.

Lightsource BP, a global leader in the development, financing and management of utility-scale solar energy projects, is the project owner and operator. All the energy from the project is being sold under a 25-year power purchase agreement (PPA) to Sunflower, a nonprofit electric utility providing wholesale generation and transmission services to six member-owners serving in central and western Kansas. The National Renewables Cooperative Organization (NRCO) played a key role in helping Sunflower develop this important project for the public power community.

Six-junction solar cell sets two world records for efficiency

Posted by in categories: solar power, sustainability

Scientists at the National Renewable Energy Laboratory (NREL) have fabricated a solar cell with an efficiency of nearly 50%.

The six-junction solar cell now holds the for the highest solar conversion efficiency at 47.1%, which was measured under concentrated illumination. A variation of the same cell also set the efficiency record under one-sun illumination at 39.2%.

“This device really demonstrates the extraordinary potential of multijunction ,” said John Geisz, a principal scientist in the High-Efficiency Crystalline Photovoltaics Group at NREL and lead author of a new paper on the record-setting cell.

Project in Morocco combines hemp and solar to go totally off grid

Posted by in categories: solar power, sustainability

A team of organizations has completed construction of a ground-breaking eco-building in Morocco that combines hemp construction with a high-tech solar energy system for total independence from the electrical grid.

The SUNIMPLANT project, designed as a single-family dwelling, was created as an entrant in the recent “Solar Decathlon” organized by the United States Department of Energy and Morocco’s Centre de recherche en Energie solaire et Energies nouvelles. The biannual international competition challenges teams of students to design and construct solar-powered buildings. The most recent edition was hosted in Ben Guerir, Morocco, the first time the competition has been held on the African continent.

“This ‘space-ship’ is advanced in time and reflects a turn not only in North Africa but in hemp construction, which doesn’t have comparable prototypes anywhere in the world,” said Monika Brümmer, a German architect and natural builder who led the project.
