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.

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario.

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

Especially for sources like wind and solar, which have discontinuous availability. While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration. We have some test cases ongoing for six months at this time,” says Minyuan “Miller” Li , first author of the study.

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF). MMBtu) in 2050. Abatement cost with hydrogen at $1/kg (7.4/MMBtu).

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.

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. Small Battery: For this scenario, they modified the base case so that the vehicle fleet is based on the Toyota Plug-in Prius. —Weis et al.
