Solar Power And Chemical Energy Systems
Renewable energy researchers have been looking into how to cut CO2 emissions from processing industrial minerals like cement and lime, as these are responsible for a high share of the global greenhouse gas emissions. For every 10 tons of cement we produce, we release 9 tons of CO2, with much of that through the burning […]
Instead of running air conditioners on fossil-fueled electricity, University of Bergamo researchers Guiseppe Franchini and Antonio Perdichizzi propose an alternative cooling technology; using a thermal form of solar energy to provide solar district cooling in the Saudi Kingdom.

An interview reveals Morocco’s secret: MASEN (the Moroccan Agency for Sustainable Energy) is actually a renewable energy “one stop shop” – starting with climate policy, through needs assessment, planning, infrastructure development and finally structuring to mobilize project finance.
The time is right to consider what went wrong and what went right with Spain’s previous CSP policy – because an election in June put the renewable-friendly coalition that developed it back in power. Spain’s socialist-led coalition government jumpstarted virtually all the Concentrated Solar Power/CSP deployed in Europe, 2.3 GW, creating a supply chain of Spanish […]
Could a Concentrated Solar Power (CSP) power plant tap the waste heat it produces to desalinate water?
