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.

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.

Dubai Plans $7.3 Billion Renewable Energy Tenders

Dubai Electricity and Water Authority has announced a comprehensive plan to significantly increase investment in renewable energy projects.

Announcing its annual budget, the Dubai Electricity and Water Authority (DEWA) stated that it will float tenders worth Dh 27 billion (US$7.35 billion) to set up renewable energy projects. The projects are expected to be commissioned through the independent power producers model.

The Authority did not give any details for the likely renewable energy projects that will be pursued. However, among the largest tenders would be for the next phase of the Mohammed bin Rashid Al Maktoum solar power park.

The first large phase of the solar park, with 200 MW capacity, is being constructed by ACWA Power-led consortium. Another tender for 800 MW capacity has attracted interest from global project developers, and the winner of this phase is expected to be announced soon.

DEWA plans to increase the total capacity of the solar park to 3 GW by 2030, so a number of tenders are expected to be issued. The Authority is expected to develop other renewable energy and clean energy projects.

Dubai has set a target to increase the share of renewable energy in its total energy mix to 7% by 2020. The medium-term and long-term targets for renewable energy share are 25% by 2030 and 75% by 2050.
