Is India Ready to Be a Solar Power Leader?

By RUPA SUBRAMANYA for ForeignPolicy.com:  Is India ripe for a renewable energy revolution? Foreign investors certainly seem to think so, and renewables have been a signature issue for Prime Minister Narendra Modi. But if revolution is indeed underway, it isn’t a spontaneous one. And taxpayer money — not just from India — is fueling the surge. New Delhi’s renewable energy aspirations recently received a major boost when Japan’s SoftBank announced a joint venture with Indian conglomerate Bharti Enterprises and Taiwan’s Foxconn Technology Group to create a new, Japanese-owned company that will bid on power contracts in India’s growing solar sector. Renewable energy, including solar, is a priority for Modi and has been since before he became the country’s leader last year. “The time has arrived for a saffron revolution, and the color of energy is saffron,” he saidon the campaign trail in 2014, attempting to symbolically link the sacred color of Hindus and his Bharatiya Janata Party with his energy dream. This joint venture is the first major announcement by a foreign investor that could help make that dream a reality.   Cont'd...

Ports/Trains - Great Non-road EV Opportunities for Utilities

Unlike on-road electric vehicle programs which can be complicated and depend, in part, upon factors outside a utilitys control, non-road programs are less risky and comparatively simple to design, operate, and control.

Case Study: Solar Tile Mount Provides Adequate Air Flow Between Solar Panels And Tile Roof

TRA Snow and Sun modifies Solar Tile Mount to adjust vertically for use on S-tile tile roofs to provide adequate air flow between solar panels and the tile roof.

New method can make cheaper solar energy storage

Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes water-splitting technologies too expensive to commercialize. EPFL scientists have now developed a simple, unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost. The work is published in Nature Communications. Many different materials have been considered for use in direct solar-to-hydrogen conversion technologies but "2-D materials" have recently been identified as promising candidates. In general these materials—which famously include graphene—have extraordinary electronic properties. However, harvesting usable amounts of solar energy requires large areas of solar panels, and it is notoriously difficult and expensive to fabricate thin films of 2-D materials at such a scale and maintain good performance. Kevin Sivula and colleagues at EPFL addressed this problem with an innovative and cheap method that uses the boundary between two non-mixing liquids. The researchers focused on one of the best 2-D materials for solar water splitting, called "tungsten diselenide". Past studies have shown that this material has a great efficiency for converting solar energy directly into hydrogen fuel while also being highly stable.   Cont'd...

Two states recently passed legislation that would require significant increases in renewable electricity generation.

Digital Inkjet Printing: An Opportunity for Further Reductions in Solar Energy Costs

With solar on the cusp of economic feasibility in many areas, incremental cost reductions such as those offered by digital inkjet printing technologies can make the difference between moving ahead with solar and sticking with electricity from the local utility

Start of test with solar energy generating noise barriers alongside highway

Alongside the A2 highway near Den Bosch, The Netherlands, two test noise barriers are installed that generate solar energy. The aim of this practical test, that was officially launched 18 June is to assess the economic and technical feasibility of this form of energy generating noise barriers. Playing a key role in the test are the LSC panels, developed by researcher Michael Debije at TU/e. The translucent, colored panels are a new type of energy source, developed jointly by TU/e. These 'luminescent solar concentrators' (LSCs) receive sun light and guide it to the side of the panels. There, it lands in concentrated form on traditional solar cells. "Thanks to their many colors the LSC are visually very attractive, which makes them ideal for use in many different situations in the built environment", explains Debije of the Department of Chemical Engineering and Chemistry, who has carried out years of research into these panels. "Further benefits are that the principle used is low cost, they can be produced in any desired, regular color, is robust, and the LSCs will even work when the sky is cloudy. That means it offers tremendous potential." Debije published his latest research findings on this subject last March in Nature. On 18 June a one-year practical test started in 's-Hertogenbosch, led by the building company Heijmans. The researchers intend to assess the feasibility of generating electricity using solar cells integrated in noise barriers or SONOBs (Solar Noise Barriers).   Cont'd...

Vanadium Flow Batteries for Global Academy of Technology (GAT) College

By implementing the IMERGY storage solution in the premises, GAT is able to store the energy produced by the PV panels during the day and use it during the non-solar time, thus eliminating the diesel generator run to provide clean power when needed.

Is Adding Solar Batteries Worth it?

Seeking to help states better address the value proposition of solar+storage systems, the Interstate Renewable Energy Council, Inc. (IREC) engaged Clean Power Research (CPR) to develop a methodology that could be used to value solar energy coupled with battery storage. The methodology described in the report can be applied in any location. It focuses on Hawaii as an example, as it is likely to be an early adopter of storage regulations.  "The concept of adding batteries alongside a utility customer's solar array intrigues utility customers, solar developers, and utility planners on several levels, but the underlying question for everyone is whether adding batteries is 'worth it,'" says Jason Keyes, Partner at Keyes, Fox & Wiedman LLP, attorney for IREC and report collaborator.  Though still at a nascent stage, the recent rapid growth in the distributed energy storage market suggests that now is an opportune time to take a closer look at distributed energy storage, especially in combination with distributed solar, and the values it has to offer. The new IREC study lays out the methodology to do just that and sets forth a pathway for more robust analysis and dialogue.   Cont'd...

Investment In Renewable Energy Yields More Jobs Than Fossil Fuel Sector

Joshua S Hill for CleanTechnica:  A new report has determined that investments in energy-efficient and renewable energy sources yield more jobs for a set amount of spending than investing in maintaining or expanding the fossil fuel industry. [wind turbine cowboy jobs] The report, Global Green Growth: Clean Energy Industrial Investment and Expanding Job Opportunities, was published earlier this week and presented at the Vienna Energy Forum 2015 by its two authors, the Global Green Growth Institute (GGGI) and the United Nations Industrial Development Organization (UNIDO). “Significant progress has already been made in overcoming the hitherto conventional wisdom that taking steps to cut GHGs is incompatible with economic growth,” said Yvo de Boer, Director-General of GGGI. “This report moves the debate another positive step forward by showing that employment and development result from sustainable, green growth.”
