Cuny developed a 100-dollar limit battery

Cuny developed a 100-dollar limit battery

During three years of research involving thousands of experiments, the CUNY chemical engineers achieved both goals by intercalating (inserting) copper into a kind of manganese dioxide known as birnessite that had been modified with the metal bismuth.

Cuny researchers developed a new battery which is able to charge thousands of times and will save a lot of energy at low costs.

The researchers were able to achieve both goals in a single battery.

They reached the “magic number” of $ 100 per kilowatt hour for energy, according to Bright.

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.

California tests battery sites

California tests battery sites

One of many battery-system components that, it is hoped, will help California bolster its power grid.

Utilities have been studying batteries nationwide. But none have moved ahead with the gusto of those in Southern California.

After the giant gas leak in Oct. 2016, Californian engineers decided to turn to another technology, batteries. 

They freed up the utilities to start installing batteries – huge battery sites.

And, as a result: it’s the worlds first battery side test of this size.  Read More

Power Storage: the options

Power Storage: the options

In Stephentown, New York, Beacon Power has build a 20MW / 5MWh plant consisting 200 carbon fiber FlyWheels.
These FlyWheels make between 3000 and 5000 cycles per year through their input in the frequency regulation market.

Power Storage: The world does have a lot of options but its still expensive.

In order to manage supply and demand our renewables, we need to store the electricity when the wind is blowing hard and the sun shines brighter than there is demand.

For instance, Berkeley wind energy experts suggest a likely average cost reduction of between 24% to 30% by 2030 and 35% to 41% by 2050 across the three wind applications studied — onshore wind, fixed-bottom offshore wind, and floating offshore wind.

There is a further 10% chance that cost reductions could be more than 40% by 2030 and more than 50% by 2050. BetterWorldSolutions offers you a number of actual, technically available options. Read More

Battery 2nd Life project

Battery 2nd Life project

Vattenfall: Our stated goal is to integrate this battery storage facility into the energy system and to give a large number of similar small local facilities access to the market through electricity trading

2nd Life project with used BMW batteries for balancing the grid. Vattenfall, BMW and Bosch test electricity storage with repurposed EV batteries in Hamburg.

  • 2,600 used battery modules from over 100 electric vehicles are being merged to form a large electricity storage facility in Hamburg
  • The stored energy is available within seconds and can help to keep the electricity grid stable

Cordelia Thielitz, General Manager Bosch Energy Storage Solutions: Electricity storage systems are a key success factor for the new energy landscape.

40% cheaper home battery

40% cheaper home battery

Peak shaving software is built-in to the sonnenBatterie pro, adjusting to your usage and rate tariff using self-learning software for optimal results in any facility without changing the way you do business.

With a home battery, people are able to to take power into their own hands. Its the key to the transition away from fossil fuels.

Recently, the German manufacturer Sonnen, introduced in the United States, a 40 percent cheaper home battery.

The 4 kWh SonnenBatterie will cost $ 5,950 including inverter.

The price is excluding installation costs. Read More

New German battery: Tesvolt

New German battery: Tesvolt

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

Bacteria instead of Lithium?

Bacteria battery by Sam Molenaar

Sam Molenaar believes that, with further optimization, the bacteria-based battery could rival the performance of lithium-ion batteries at a lower cost and with greater safety.

A rechargeable battery driven by bacteria? Lithium-ion batteries are limited by safety issues, high costs and other factors. Sam Molenaar and his colleagues from Wageningen University wanted to come up with a less expensive, more sustainable solution. 

The research team combined two separate microbial energy systems. One system used bacteria to form acetate from electricity, while the other one converted the produced acetate back into electricity. Read More

LFP or NMC battery?

LPF or NMP battery?

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

Molten Salt Batteries are cheap, simple and havethe potential for an infinite life

The energy storage market is blossoming. Because we need renewable energy storage to supply our smart electrical grids at daily moments the demand for energy is high.

The Molten Salt Battery is a battery to watch right now. An overview. 

In Molten Salt Batteries (also known as liquid metal batteries) two liquid electrodes are separated by a molten salt electrolyte.

Characteristic of salts is that these are guiding in the liquid state because the ions are allowed to move freely. The salt and the electrodes separate themselves by their different densities and immiscibility. Read More
