New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. The new sodium-based molten salt battery uses two distinct reactions. of peak charge capacity.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

As the pressure to decarbonize electricity grids mounts, so does the need to have long-term storage options for power generated from renewables. Especially for sources like wind and solar, which have discontinuous availability. He expects the battery to retain over 80% of its charge in that period.

ARPA-E announces $12M for five projects in nuclear materials science; first OPEN+ cohort

Green Car Congress

The OPEN+ advanced nuclear projects are: Additive Manufacturing of Spacer Grids for Nuclear Reactors, Carnegie Mellon University, $1,000,000. Spacer grids are used to provide mechanical support to nuclear fuel rods within a reactor and reduce vibration, and they are a particularly difficult component to manufacture.

ARPA-E awarding up to $24M to 10 projects to support advanced nuclear power plants

Green Car Congress

Nuclear power generates nearly 20% of US electricity, delivering reliable, low-emission baseload power to the grid. A quantitative assessment will be done on the continuous load following capability of the proposed system that would be capable of sharing the grid with substantial renewable resources such as wind and solar.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

One of the main impediments to harnessing solar energy is storage. Solar batteries work as a short-term solution, but not when it comes to long-term storage or to power, say, an entire city. Solar energy and oil wells might sound like an odd combination, but the principle is similar to how geothermal energy would be harnessed.

ARPA-E awarding $30M to 12 hybrid solar projects; conversion and storage

Green Car Congress

Under the FOCUS program, projects will develop advanced solar converters that turn sunlight into electricity for immediate use, while also producing heat that can be stored at low cost for later use as well as innovative storage systems that accept both heat and electricity from variable solar sources.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

As countries transition away from fossil fuels to green sources of energy like wind and solar, there will be natural lulls in energy production due to weather conditions. Energy consumption also tends to peak during early evening hours , which is inconveniently right when solar energy output decreases.
