Solar-heated cement calcining: “This is the key point: not only are we addressing carbon emissions from the heat input, which is traditionally supplied by fossil fuels, we’re also addressing the CO2 naturally liberated from calcining the calcium carbonate.” Solar-heated cement calcining – aided by the greenhouse effect? Researchers at Sandia National Laboratories are advancing a …

How to help invent the transition to a decarbonized world – research work in concentrated solar. Lina Hockaday and colleagues at Stellenbosch University attending the 2017 SolarPACES Conference Work in concentrated solar research is one rewarding way to help invent the transition to a decarbonized world SolarPACES talks to concentrated solar energy researchers at various …

Carbon sequestration in mining waste over the past 50 years can be seen at BPH Group’s Australian nickel mine at Mt Keith. The mineral wastes have weathered and become bluer and then whiter, indicating the changed chemical composition as it sequesters CO2. Australian researchers propose using solar power to capture and store carbon in mining …

IMAGE©Valparaiso University The solar lab at Valparaiso University: This solar furnace uses a horizontal, on-axis optical configuration. A heliostat reflects solar radiation into a faceted, spherical concentrator comprising 305 hexagonal mirrors. The concentrator has a focal length of 5.77 m and a rim angle of approximately 20°. It focuses the radiation to an approximately 6 …
Professor Celia Sobrino, who teaches Thermal and Fluids Engineering at Universidad Carlos III de Madrid, describes how TOPCSP aims to increase the supply of solar engineering researchers TOPCSP, a new doctoral network aims to be the first PhD training program to respond to the growing need for qualified CSP researchers New ways are being developed …
