Will the US Demo Long-duration Energy Storage in Time?
In a new study from Sandia National Laboratories; The Value of Long-Duration Energy Storage: Policy and Perception, researchers have published details regarding policies pertaining to long-duration energy storage (LDES), including feedback from around 500...
Mining Tech shows How Particle CSP can Hoist Tons of Hot Sand
At any one time, almost 3 tons of hot sand would be in free fall for about 5 seconds hitting the pile beneath at 60 meters a second
CEMEX and Synhelion ace the First “Hot Solar” Cement Trial
By the middle of the 21st century the global energy system will hopefully be very different, with clean energy, clean fuels and clean heat supporting a highly decarbonized future. It will require so many changes in how we have done these things so far, that we can...
How China’s Cosin Solar Solved Some Tower CSP Challenges
Known then as Supcon Solar, Cosin Solar developed two tower projects in China's pilot CSP (Concentrated Solar Power) program; as technology and core equipment provider on PowerChina Gonghe 50MW tower CSP, and developing the Supcon Delingha 50MW tower CSP. These were...
How Did Cosin Solar Tower CSP Reach Projected Performance So Fast?
Cosin Solar (previously Supcon Solar) seemed to burst on the global Concentrated Solar Power (CSP) scene as a fully fledged Chinese CSP firm. Among China’s pilot projects, the Supcon Delingha 50 MW tower CSP with 7 hours of storage in Qinghai Province was among the...
Researchers in Australia Investigate Open Vortex Solar Receiver for Thermochemistry at 1000°C
Alumina calcination is one industrial process that could be decarbonized using a 1000°C “hot solar” process
NREL Results Support Cheap Long Duration Energy Storage in Hot Sand
There aren’t many novel clean energy technologies that could also directly remove fossil energy plants. The US National Renewable Energy Laboratory (NREL) has created one. Long duration storage at grid scale is crucial to meeting climate targets. Solar PV and wind...
Namibia to De-Risk CSP with Permitted Siting and BOOT Finance
Namibia to follow Moroccan clean energy policy to cut CSP developer risk
World’s Largest Energy Firm to Build Three Chinese CSP Projects
The largest clean energy investor and developer in the world built the Three Gorges Dam China Three Gorges Renewables - the developer and builder of the 22.5 GW Three Gorges Dam in China - will develop three of China's planned new 100 MW Concentrated Solar Power (CSP)...
China’s Big State-Owned Firms Begin New CSP for 2024
Could giant coal and nuclear developers build CSP? In China, yes
Volateq Brings Drone Monitoring Subscriptions for Trough Solar Thermal Energy
Drone monitoring of solar fields is already established for photovoltaic solar. Now a new DLR spinoff - Volateq.de brings drone technology to the very different challenges of monitoring solar field performance, for concentrated solar power (CSP). “There's a lot of lot...
New Sulfur-Based Solar Reactor Makes Cheap Green Hydrogen for Copper Mines
By making solar hydrogen as an industrial service for copper mining the scale is established for mass production
Absolicon Investigates Wastewater Sludge Drying with 140°C Solar Heat
Yet another use for industrial solar heat – drying wastewater sludge – attracts study at six-minute solar collector maker Absolicon
Hot Solar Biomass Gasifier Makes Clean Hydrogen-Rich Syngas
Biomass gasification using steam and oxygen is an already mature technology for extracting hydrogen, which requires heat at above 700°C. To generate the heat for gasification, traditionally, some of the biomass itself is burnt. But this combustion emits several...
Advance Hot Solar Fuels with “Spillover” Policies
A pair of policy researchers at Potsdam University’s Institute for Advanced Sustainability Studies in Germany have a suggestion for policy to advance high temperature Concentrated Solar Thermal (CST) technologies. Today’s commercially operating Concentrated Solar...
The Economics of Running CSP as a Capacity Resource in the 100% Renewable Future
A new paper to be published in the journal Energy Conversion and Management: X: Using Concentrating-Solar-Power Plants as Economic Carbon-Free Capacity Resources - develops an approach to assessing the capacity contribution from CSP plants with thermal energy storage...
Why Likana’s 24-Hour Solar Bid under $34/MWh Lost in Chile
At the annual SolarPACES Conference (held virtually for the second year) Cerro Dominador’s CEO Fernando Gonzalez answered questions from the international network of concentrated solar power (CSP) researchers and developers attending about exactly what happened in the...
Have Heliostat Cost Cuts Helped Likana Bid CSP Under 4 Cents?
Have advances in heliostat mirror solar fields enabled record low prices in Morocco and Dubai and low bids like for Likana in Chile?
Why Lunar Engineering is an Exciting R&D Field for the “Hot Solar”
Out-of-this-world engineering challenges of manufacturing on the Moon hold promise for Concentrated Solar Thermal (CST)
