A very large-scale long duration energy storage (LDES) idea from MIT envisages a 1 kilometer-long, 60 meter-wide lidded central storage container of rocks sunk 20 meters down into the ground - about the size of 10 football fields if they were laid end to end. The idea...
DOE workshops educate regulators on long duration energy storage (LDES) A Federal energy project funded through the US Department of Energy (DOE) Office of Electricity has initiated workshops designed to help state utility regulators determine best practices in...
A perovskite may be more cost-effective than ceria for solar-driven thermochemical hydrogen production, a new paper suggests. One perovskite formulation that works at a slightly lower temperature than ceria is explored by Xin Qian in the paper Outstanding Properties...
Researchers at DLR, and NREL, and the Bill Gates-funded start-up Malta have been investigating converting coal plants into grid-scale thermal energy storage for curtailed intermittent renewable energy, as low-cost heat “batteries.” (Thermal energy storage was...
The MIT team estimates their thermal “battery” designed for long duration - 100 hours or more - would be half the cost of today’s cheapest grid-scale energy storage; pumped hydro. A very intriguing idea for long-duration gigawatt-scale grid thermal energy storage...
One of the ways to cut costs in thermal energy storage, whether standalone or as part of tower Concentrated Solar Power (CSP) is to use heat transfer fluids able to reach higher temperatures, and with a wider working range between hot and cold than today’s molten...
HelioHeat’s 1,000°C heat at just 1 Cent/kWh potentially ends the use of fossil energy for the production of steel, cement, food and chemicals
Research – and deployment – of low cost and sustainable energy storage technologies are crucial to the long term survival of humans
As a vital component of fertilizers, ammonia (NH3) is the second most-produced industrial chemical in the world. Annual production is around 180 million metric tons and almost 90% of this production goes to meet the global demand for agricultural production....
Synhelion will produce concentrated solar heat at 1500°C for the cement plant and receive highly concentrated CO2 to produce synthetic fuels
South Africa's Bokpoort performance has been "reliably excellent" SolarPACES spoke with Nandu Bhula who has been with the team responsible for the success of ACWA Power’s 50 MW Bokpoort trough Concentrated Solar Power (CSP) plant in South Africa since the start, first...
“With the asymmetry of flux levels from the solar field; why not make the receiver also asymmetric to fit better with that,” she explained.
Solar PV for electricity is great, but the world needs solar fuels too, fuel for planes, fuel for ships and fuel for steel and cement.
What are the policies that make it possible to actually meet a renewable energy target? Regulators can’t simply decree it happens
A state of the art assessment of day or night solar thermochemistry at very high temperatures 1,000ºC to 2,000ºC
Solatom’s Fresnel solar module is shipped ready to go and connected onsite as a turn-key design to generate steam or high pressure hot water
When Bernie Sanders proposed building publicly owned renewables it was dismissed as pie in the sky. But a US agency once did exactly that
Commercializing alumina refining using solar heat Approximately 27% of Australia’s industrial carbon emissions come from alumina refineries, in which fossil fuels are burned to heat the processes. But concentrated solar thermal (CST) could provide up to half of the...
What if the more bankable trough technology could run on molten salt, like the more efficient tower CSP? Wouldn’t that leverage the best of each technology?
Engineers generally tend to be solutions-oriented, and engineers in Concentrating Solar Power (CSP) are no different. A history of making things better than they were is why we now have advanced technologies. As Hal Harvey, founder of Energy Innovation told the NYT...
