Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

2021 was a big year for energy-related news, what with the ongoing hunt for new forms of energy storage and cleaner if not carbon-free electricity and events and research that spotlighted the weak links in our power grid. No battery is perfect, however, so engineers keep pushing for new and improved ways to store those electrons.

PNNL study finds 2028 grid resource adequacy likely sufficient for high EV penetration; managed charging strategies can double adequacy

Green Car Congress

A new study of the impact of high EV adoption on the Western US power grid by a team from Pacific Northwest National Laboratory (PNNL) has found that 2028 grid resource adequacy—from generation through transmission—is likely to be sufficient for high EV penetration.

$50M Battery500 consortium targeting battery pack with specific energy of 500 Wh/kg

Green Car Congress

The team in this 5-year project hopes to reach these goals by focusing on lithium-metal batteries, which use lithium instead of graphite for the battery’s anode. While studying these materials, the consortium will work to prevent unwanted side reactions in the whole battery that weaken a battery’s performance.

This Clock Made Power Grids Possible

Cars That Think

As more power stations adopted the clocks, the frequency regulation allowed them to share electricity and create an interconnected power grid. which produced battery-operated clocks. Unfortunately, these early clocks were lousy timekeepers, their ability to keep time deteriorating along with the battery.

Arizona State University Professor’s Work to Stabilize the Grid Pays Off

Cars That Think

Whenever new technologies are introduced into the power grid, there’s always a chance they could disrupt the system, possibly even leading to blackouts. Finding ways to deal with the impact on the grid caused by incorporating renewable energy has been the focus of Vijay Vittal ’s research for nearly 20 years.

How to Build a Power Grid on the Moon

Cars That Think

Batteries lose capacity, and their liquid components freeze, requiring a power-hungry cycle of using much of the power in batteries just to heat themselves. But to power the early years of the Artemis base, the company expects that NASA will adopt Astrobotic’s fully solar-powered LunaGrid.

MIT study concludes V2G-enabled electric commercial trucks could offer lower total operating cost than conventional diesel fleet

Green Car Congress

The CTL study was conducted using data collected by the international office supplier Staples, as well as ISO New England, the nonprofit firm that runs New England’s electric power grid. In such a setup, truck owners would be paid by utility firms for the power services they provide.
