The US Federal Energy Regulatory Commission (FERC) has revised its rules to class energy storage as a power source that can be connected to the grid.

The FERC has amended Order 792 that previously only applied to small generators to also include energy storage. The order now includes storage in the category of resources eligible to interconnect to the power grid under the Small Generator Interconnection Procedures (SGIP) and/or Fast Track Process.

On issuing Order 792 the FERC said it had made the revision “to ensure that the rates, terms and conditions under which public utilities provide interconnection service to Small Generating Facilities remain just and reasonable and not unduly discriminatory.”

The Electricity Storage Association (ESA) welcomed the news and commended the FERC for acknowledging that energy storage should participate in this class and that rules and policies should evolve. ESA Chairman Darrel Hayslip said: “These reforms are good news for storage project developers and further facilitate the deployment of storage on the power grid.”

Porous Power Technologies (PPT) has launched a line of ceramic-filled battery separators designed to improve the thermal stability and safety of the large-format lithium-ion batteries used in electric vehicles, flat-cell consumer electronics, and high-power applications.

Under heat, the ceramic-filled polymer separators fuse together, leaving a thin film of ceramic particles between the electrodes and reduce the likelihood of hard shorts that can lead to thermal runaway and cell failure.

The ceramic particles are evenly distributed throughout the PPT chemically inert PVDF polymer. The particles reside primarily in the pore walls, leaving a large and uniform open pore structure that enable ions to pass through with less resistance and less heat generation.

The separators will provide greater power in high-current applications as well as having increased thermal stability with less cell degradation. The design offers reduced separator shrinkage, extended cycle life, higher bake-out and operating temperatures, and improved puncture and abuse resistance.

China Racing has announced it will be taking part in the Formula E Championship electric vehicle race series in 2014. China Racing is the second of ten teams to be confirmed for the zero-emission race after UK-based Drayson Racing Technologies.

The teams will race on street circuits in ten cities across the world in electric cars. The cars for the inaugural year are being designed by McClaren, Spark Racing Technology and Dallara. All teams have the opportunity to use the customer car for the first year and encouraged to build their own cars for races in the following years. With support from Chinese automotive makers China Racing hopes to build a team car within three years.

Alejandro Agag, Chief Executive Officer of Formula E Holdings said: “China has enormous potential for the expansion of electric vehicles as a tool to fight pollution in cities. We think the FIA Formula E Championship can be a powerful tool to make electric cars popular with the Chinese public, particularly the younger generations. Having a Chinese team with us in the Championship will be key to succeeding in that challenge.”

An energy efficient heating system offering efficiency savings of up to 20% could be key in the transition to low-carbon energy systems in Europe. This is according to a report commissioned by SSE (UK energy generators and distributors) and Dimplex (a global heating solutions firm).

The smart electric thermal storage (SETS) system works by storing up renewably produced energy when production is high but demand is low. The report indicated SETS could provide up to 54GW of additional flexible storage capacity across Europe by 2050, enabling renewable electricity to be stored when demand is low and used to heat homes when needed.

The system, first brought to the market by SEE and Dimplex in a product called Quantum, is intended to replace out-dated night storage heaters with something more efficient and with better room temperature control as well as being designed for smart grid integration.

The report found that if all 27 EU countries replaced storage heaters with SETS, savings of 7.4TWh of electricity and three mega-tons of CO₂ could be made each year. If used in all electrically heated homes as much as 148GW could be provided by 2050.

Stuart Mackenzie, Managing Director of Dimplex, added: “Quantum offers consumers with electric storage heaters the opportunity to reduce their running costs by up to 27%. It’s also a Green Deal approved measure, so the capital cost outlay can be substantially reduced.”
