IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. While there are many effective solutions for daily energy storage, the most common being batteries, a cost-effective long-term solution is still lacking. Dabek, P.B.,

Utility solar dethrones coal as the cheapest power source in Asia

Baua Electric

Photo: China News Service Renewable energy costs in Asia last year were 13% cheaper than coal and are expected to be 32% cheaper by 2030, according to a new study. The driving force behind this trend is the substantial reduction in capital costs for renewable energy projects.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Especially for sources like wind and solar, which have discontinuous availability. Scientists have been looking for solutions in gravity energy storage , thermal or geothermal storage , and also molten-salt batteries. He expects the battery to retain over 80% of its charge in that period.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones. —Huskinson et al.

Stanford researchers develop copper-based catalyst that produces ethanol from CO at room temperature; potential for closed-loop CO2-to-fuel process

Green Car Congress

—Matthew Kanan, an assistant professor of chemistry at Stanford and coauthor of the Nature study. For the Nature study, Kanan and Li built an electrochemical cell: two electrodes placed in water saturated with carbon monoxide gas. We have a solution to this problem that’s made of copper, which is cheap and abundant.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

As we try to objectively study nature, we are often reminded of how natural forces affect us personally. A Battery for Heat Made from Sand Noted chemical engineer Donald Sadoway is quoted as saying: “If you want to make a dirt-cheap battery, you have to make it out of dirt.” Sand is efficient, nontoxic, portable, and cheap!”. “We
