GE and Arista Partner on Renewable Energy




Arista designs and makes renewable energy systems and has partnered with GE to use their Durathon™Battery for their “Power on Demand” offering.

Power on Demand system uses renewable energy (wind, solar, …) and storage devices to keep that energy available for peak use.  Power on Demand can reduce energy costs by smoothing the demand for grid power and using stored power at peak times when energy charges are highest.

"“ … a custom-designed battery storage system and proprietary real-time demand monitoring technology. … releasing stored power only during peak demand periods, thereby reducing peak demand charges, … and lowering commercial electricity costs.”

GE’s Durathon Batteries are both smaller and lighter than traditional batteries, can last up to 20 years and are recyclable.

Panasonic Technology for Hybrid Car Carrier




 

Panasonic along with Mitsui O.S.K Lines, Ltd. and Mitsubishi Heavy Industries are working on technologies to reduce CO2 emissions from ocean going ships.

The test platform is the “EMERALD ACE”.  The ship will be fitted with “ … solar panels (160kW planned) and lithium-ion rechargeable batteries (approximately 2.2MWh planned) … “

The solar panels charge batteries that provide power when in the harbor – in place of diesel generators reducing CO2 emissions.  The batteries are used as ballast and do not impact the carrying capacity of the ship.

Compact wall-mounted electric vehicle charging




Charge your electric vehicle battery

GE charging station can be installed in the garage and quickly charge your electric vehicle to be ready for the next day’s commute.  The NEMA rating enables the device to be installed outdoors, if your situation requires.  …GE  wall-mounted electric vehicle charger is the Wattstation

…   “The GE WattStation Wall Mount delivers a full-cycle charge to a 24kWh battery in only 4-8 hours, whereas plugging an EV into a standard electrical outlet would require 12-18 hours to provide the same level of charge. 

Suitable for both indoor and outdoor installations, the GE WattStation Wall Mount is NEMA 3R rated to resist rain, sleet and even ice.

The unit measures only 24 inches tall, 16 inches wide and 6 inches deep.”   …

Sumitomo Electric Develops Improved Lithium Battery Materials–Aluminum Celmet




Sumitomo Electric has developed a new metal that is adaptable for hybrid car batteries.

The material, Aluminum-Celmet is low in resistance and light and easily processed by cutting or shaping. 

“ … features lead to favorable filling, retaining and current-collecting performance, … recently been adopted as a positive electrode current collector in hybrid vehicle nickel-hydrogen batteries.”

Sumitomo’s studies show that it can increase battery capacity between 1.5 x and 3 x.  Another way to view this is that for a given charge capacity a battery footprint can be 1/3 to 2/3 smaller by volume.

Storage key to solar photovoltaic power success




Storing and concentrating the power generated from solar panels so that it can be used throughout the day is key to driving utilization of this form of renewable energy.  StoragePumped hydro storage technologies range from batteries to pumped hydro.  The pumped hydro storage technique stores energy in the form of water, which has been pumped from a lower elevation to a higher elevation reservoir.  Then, when demand increases, the stored water is released to power turbines.  …

Viridity Energy and SEPTA to "Recycle" Subway Braking Energy




Viridity logo

SEPTA and Viridity Energy are working to reclaim and then reuse or resell the electricity generated by SEPTA subway and trolley cars. 

Much the same as a hybrid auto using regenerative braking to charge a battery - this system  sends the energy generated from braking subway cars back to the Subway power system for short term storage.  This turns the normally wasted energy into a resource.

Viridity Energy 's solution will " ... allow SEPTA to recycle the energy created from the regenerative braking ability of trains and trolleys ... ".  The braking energy will be stored in a large battery.

Benefits will include energy savings by storing the energy that can then be used to reduce SEPTA's draw from the GRID or even returned to the GRID for revenue during peaks use times.  It is projected that energy savings will result in over 1,200 tons of carbon emissions avoided per year and helping " ... balance electric generation and electric load on the PJM interconnection ..."
