Molten storage and thermophotovoltaics offer new solar power pathway

Georgia Institute of Technology:  New computer modeling suggests that high temperature TPV conversion -- which captures infrared radiation from very hot surfaces -- could one day rival combined-cycle turbine systems when combined with thermal storage using liquid metal at temperatures around 1,300 degrees Celsius. Advances in high-temperature components and improved system modeling, combined with the potential for conversion costs an order of magnitude lower than those of turbines, suggest that TPV could offer a pathway for efficiently storing and producing electrical power from solar thermal sources, a new study suggests.

The underlying technologies of high temperature storage and thermophotovoltaic conversion could also be used to produce grid-scale batteries able to rapidly supplement other power sources by storing heat for quick conversion to electricity. The research, supported by ARPA-E, was reported July 4 in the journal Energy and Environmental Science by researchers at the Georgia Institute of Technology.  Cont'd...

SolarReserve Receives Environmental Approval For 260 Megawatt Baseload Solar Plant in Chile

Copiapó Solar Project in the Atacama achieves important milestone to meet Chile's growing energy demands and provide energy security


A South Carolina inventor has developed what is said to be THE new choice for solar hot water technology. The Rocket Dome, uses the power of the Sun's warming rays to heat water-similar to a black garden hose laying on the ground on a hot summer's day. It is able to store 200 gallons of clean potable hot water for domestic use or capable of heating a swimming pool for extended swimming seasons. The Rocket Dome is SRCC certified and made in USA.


Sun Bandit® by Next Generation Energy® has reached new heights in setting new standards for solar water heating. Sun Bandit's patented micro-grid technology has defined a new category for solar water heating, influencing new Solar Rating Certification Corporation (ICC-SRCC) OG-100 and OG-300 standards. The result? The world's first and only OG-100 certification for a PV-based solar thermal water heating collector for Sun Bandit.

Positive outlook for some European solar thermal market segments, despite disappointing overall results

Growth potential has been identified in some market segments, particularly in the booming decentralized large-scale heating sector in Denmark.

The European Commission Renewable Energy Progress Report: indicative targets for solar thermal energy are not being met.
