Harvard new nontoxic Battery

Harvard new nontoxic Battery Team

By modifying the structures of molecules used in the positive and negative electrolyte solutions, and making them water soluble, the Harvard team was able to engineer a battery that loses only one percent of its capacity per 1000 cycles.

Harvard scientists have developed a new flow battery which stores energy in liquid, works 10 years without energy loss and is much safer than lithium-ion batteries.

After a few years of heavy use, most lithium-ion batteries suddenly loose a lot of storage capacity. You surely recognize this from your smartphone, but that’s also a problem for energy storage which should last a very long time to store solar energy. Scientists at Harvard University have found a possible solution.

The new technology promises a battery definitely lasting ten years without losing much capacity. The solution is applied to a so-called flow-battery. The flow battery stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.

US Energy Storage Update

US energy storage plants

Tehachapi is nominally a wind energy-related project attached to the 4.5 GW.
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.

This blog focuses on the Borrego Springs, Tehachapiand and Notrees energy storage projects and examines the long-term impact that they will have on the future project pipeline in the US.

According to the Energy Storage Association’s US Energy Storage Monitor, 60.3 MW of storage was deployed in the third quarter of 2015, a twofold year-on-year increase.

Portugal 72 hours on renewables

Portugal 72 hours on renewables

Last week the German government reported that the Portugal produced so much renewable energy on a particularly sunny, windy Sunday that there was a power surplus.

In may 2016, Portugal ran for more than half a week without having to resort to fossil fuels.
Thanks to a big push toward solar, wind, and hydro power and a little nudge from the EU, for four days, Portugal produced enough clean, sustainable electricity to meet the needs of its people. Read More

Saltwater Battery gets $ 33 mln

Aquion SeaWater Battery

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.

Saltwater conductor

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.”

Advantages

  1. Saltwater batteries are tolerant to wide temperature ranges, partial state of charge cycling, and daily deep cycling with minimal degradation.
  2. 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.
  3. 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.

Latest news: 24-volt version Hybrid Ion battery

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.
