EU Roadmap Energy Storage 2030 recommends options to boost the share of renewable energy in the European energy storage market
This Roadmap and recommendations aim to describe the future European needs for energy storage in the period towards 2020-2030. It also gives recommendations on which development will be required to meet the needs. Read More
Tehachapi is nominally a wind energy-related project attached to the 4.5 GW Tehachapi Wind Resource Area, although in actual fact the plant was conceived as a two-year test bed for a wide range of potential grid applications. When it opened, in September 2014, it was credited with being the largest battery storage project in the North of the US, with 604,832 Li-ion cells housed in 10,872 modules.
Everyone knows California and New York do have behind-the-meter energy storage at a large scale. But there are some sleeper states where the economics already work.
The Tesvolt storage system is available in six different versions from 10 to 120 kWh which can be combined. For a large-scale storage system with a capacity of 1 MWh, a ready-made container is available at Tesvolt
The German companies SegenSolar and manufacturer Tesvolt introduced an Lithium energy storage system of 30 kWh and more.
Each cell in the system can be controlled separately, which ensures a long-lasting effect.
SegenSolar, a large solar power company, intends to sell the Tesvolt energy storage system online and via various distribution centers worldwide. Read More
Aquion did come up with a breakthrough saltwater battery. It is environmentally friendly, cost effective and has a life cycle way beyond any other battery: up to 5,000 cycles.
The development of sustainable saltwater batteries enters the next level.
The American company Aquion Energy has received $ 33 million extra finance.
Previously, Bill Gates invested in Aquion Energy.
Aquion developed batteries that can store solar and wind energy to serve as backup for times when there is no wind nor sun. Saltwater batteries are not new, but the batteries from Aquion are special because they are using salt water as a conductor, instead of acids or bases.
Aquion has come up with a clever twist on a 200 year old salt water battery technology using:
Activated carbon (anode)
Manganese oxide (cathode)
And basically a salt water electrolyte
They have come up with a breakthrough solution. It is environmentally friendly, cost effective and has a life cycle way beyond any other battery: up to 5,000 cycles
So what’s Aquion’s energy storage innovation?
The startup — which was backed by Bill Gates and VCs like Kleiner Perkins and Foundation Capital — is making a low cost, modular grid battery made from basic materials like sodium and water.
The battery pairs a carbon anode with a sodium-based cathode, and a water-based electrolyte shuttles ions between the two electrodes during charging and discharging.
The technology was developed out of Carnegie Mellon University by founder and chief technology officer Jay Whitacre.
By using basic materials, Aquion is hoping its product is inexpensive enough to disrupt the current grid battery market.
Aquion’s CEO Scott Pearson:
“When the battery has been manufactured at a commercial scale for awhile, the price point of the battery could be $300 per kilowatt hour. That’s about a third of the cost of some of the more expensive lithium ion battery grid products.”
Saltwater batteries are tolerant to wide temperature ranges, partial state of charge cycling, and daily deep cycling with minimal degradation.
In addition to the safety and sustainability advantages of using water as electrolyte, another advantage is the thermal mass of the embodied water means that Aquion products neither heat nor cool rapidly. As such, the products can operate in a very wide operating temperature window because they simply take so long to heat and to cool.
The saltwater battery chemistry relies on charge/discharge mechanisms which are unaffected by partial state of charge – these batteries can sit indefinitely at partial, or even no state of charge, without irreversible capacity loss like lead acid batteries.
In June 2016, Aquion Energy has introduced the Aspen 24S, a 24-volt version of its award-winning Aqueous Hybrid Ion (AHI) battery.
The new product is designed for energy-intensive applications that use solar panels, such as off-grid solar-powered LED lighting, as well as small pumps and motors. It is also an ideal drop-in replacement for existing systems using 24-volt lead-acid batteries.
Gildemeister considers the Australian market one of enormous potential and suitability for storage systems like the CellCube
Vanadium Australia has a deal with German battery maker Gildemeister Energy Storage to sell the CellCube range of vanadium redox flow batteries (VRFB) in Australia, as part of the company’s plans to take on the large-scale solar and energy storage market.
The deal with local commercial solar installer Sun Connect, will allow Australian Vanadium (AVL) to ramp up its activity in Australia’s commercial and utility-scale battery markets. Read More
The LFP battery is still preferred because of its low energy density. But, NMC batteries are slowly taken over because of their higher energy density.
Batteries are booming business. In the energy world, the Lithium-Iron Battery (LFP) still has a lot of advantages. Because of its low energy density, this battery is pre-eminently suited for Energy buffers (stationary storage).
However, we see that NMC batteries are slowly taken the position of the LFP because of their higher energy density and because prices are leveling. Read More
in 2014, companies in the electric transportation sector accounted for 820 million euro.
In 2014, the number of employments in electric vehicles increased by 25% to 3,200 jobs in the Netherlands.
Dutch companies in circular electric transport are doing a great job. National and international. Important, because they do not only contribute to our economy but they also are part of the solution to the global energy and climate issues. Read More
