Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

Batteries that can hold large amounts of energy are large and expensive, requiring a substantial investment to install. Energy storage has two main factors—how fast it can be charged and discharged (the spigot) and how much total energy it can hold (the bathtub). But Liu says residential customers don’t see demand charges.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

The California-based Hyperlight Energy will be piloting an installation where they plan to use existing oil wells as solar thermal wellsprings, with the stored energy being converted back to clean electricity when required. A possible answer, though, might lie in oil wells.

This Fusion Reactor Is Held Together With Tape

Cars That Think

Gretchen Ertl/CFS/MIT Plasma Science and Fusion Center What sets CFS’s technology apart is its use of high-temperature superconducting tape, which is layered and stacked to create extremely strong electromagnets that will shape and confine the unruly plasma and keep the bulk of the charged particles away from the tokamak’s walls.

What is Home energy management system, why it is needed

Baua Electric

Renewable energy integration involves the incorporation of renewable energy sources into existing energy systems, such as electrical grids or heating systems. Because they usually sit for a long period of time, their charging can be shifted to periods when either solar generation is high or electricity prices are low.

Five Cool Tech Demos From the ARPA-E Summit

Cars That Think

There’s another benefit to this battery, and this one will make EV drivers very happy: It will take only 10 minutes to reach an 80 percent charge in EVs powered by these batteries, Rustomji estimates. The rare earth oxide then undergoes a molten-salt electrolysis process that converts it into a solid metal form.

New $30M ARPA-E program to develop new solar conversion and storage technologies; targeting higher solar penetration in mix

Green Car Congress

The high cost of grid electricity storage makes it best suited for high-value, short-term, frequency regulation; the lower value market for peak-shifted photovoltaic electricity is largely unprofitable, except where geography provides suitable reservoirs for lower-cost pumped-storage hydroelectricity. —DE-FOA-0000949.
