The energy-storage goal of a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use has been achieved by a team of Penn State materials scientists. The key is a unique three-dimensional sandwich-like structure that protects the dense electric field in the polymer/ceramic composite from dielectric breakdown. Their results are published today (Aug. 22) in the Proceedings of the National Academy of Sciences (PNAS).

In a fast-developing industry teeming with technologies that promise to be the next big thing, energy storage appears to be the biggest.
US-based storage provider AES Energy Storage, a subsidiary of AES Corporation, has signed contracts with utility San Diego Gas and Electric (SDG&E) to install two energy storage arrays with a combined capacity of 37.5MW.
SDG&E was already bidding out storage projects when California regulators said they wanted to pick up the pace, allowing the utility to have the AES project on the table within months. The CPUC is pushing for expedited deployment to

ARLINGTON, Va.–(BUSINESS WIRE)–
RICHMOND, Calif. — Axiom Exergy announced it has raised $2.5 million from investors to assist in scaling its thermal energy storage solution in the grocery store and cold storage facility markets. By utilizing its Refrigeration Battery, Axiom said businesses like supermarkets and food distribution centers can reduce their peak energy demand by up to 40 percent and protect perishable inventory from spoiling during power outages with dedicated backup cooling.
HERNDON, Va.–(BUSINESS WIRE)–Greensmith Energy, one of the largest providers of energy storage software and integration services, announced today that AltaGas Ltd. has selected Greensmith as the software provider and system integrator for a 20 MW/80MWh system in Pomona, California. Together, AltaGas and Greensmith will deploy a state-of-the-art 20 MW energy storage system to help with Resource Adequacy in California and offer multiple other grid applications. The project will be expedited and is expected to be completed in December 2016.

The oil and gas giants have fallen on tough times. We’re not talking can’t-afford-a-meal tough — they still have billions in cash lying around — but not-raking-in-billions-in-profit tough. Booms and busts have always rocked this industry, so executives could make a case for sitting on their cash until oil prices rebound and prosperous times return.
