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

Startup explores commercial opportunities SolarCar

SolarCar might be introduced on the market

SolarCar Stella completed and won a six-day, 3,000-kilometer race from Darwin to Adelaide across the Australian outback, with an average speed of 67 km/h and with three people on board.
The car also achieved a top speed of 120 km/h with a full load of four people, demonstrating the horsepower of this solar-powered vehicle.

Atlas Technologies – the startup of former students of the Technical University Eindhoven – explores whether the family car powered by solar energy, could be a commercial success.

During their study, the former students designed the solar family cars Stella and Stella Lux.

These solar-powered cars won in 2013 and 2015, the World Solar Challenge, a race for solar cars. Read More

Energy storage on the bottom of the sea

energy storage at sea

A worldwide survey had identified potential StEnSEA sites with a cumulative storage capacity of around 817 terawatt-hours.

Why not store energy In hollow tanks on the bottom of the sea? The German Fraunhofer Institute started a test with spherical storage tanks.

In November 2016, the first tank has been placed at the bottom of the Bodensee, near the German border with Switzerland.

Ultimately, the aim is to place the tanks in the area of offshore wind farms. But for now, the institute choose the lake because it is more practical for the tests. 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

The Gravity Battery Concept

solar power will increase by 80% the next 3 years

Green power: Global investments reached USD 300 billion. A relatively large proportion of these billions has been done by emerging countries such as Burundi, Kenya, Honduras, Jordan and Uruguay.

A gravity battery could be created by using an energy source to slowly lift a large weight (using gearing or pulleys), then discharged by lowering the weight to run a generator when needed.

The gravity battery consists a tube, weight, cable and coil. When the weight is up, the battery is considered charged. Read More

Can we repurpose EV batteries?

 Can we repurpose EV batteries?

V-Storage started a pilot using old batteries from busses as an energy storage system. The ‘old’ batteries are placed in a large container. They intent to use the stored energy to electrify busses and to increase the Grid Balance. The pilot will start in January 2017.

In four or five years, the batteries in the roughly one and a quarter million EVs currently on the road are going to start to wane. EV owners will either replace them, or replace the cars entirely.

That means we’ll have a lot of used batteries (with plenty of life left in them) but which are no longer suitable for EVs. What to do?

One possibility is repurposing them to serve as grid-connected energy storage.

Storage is valuable to the grid for many reasons, including its ability to smooth out fluctuations in supply, allowing for more integration of variable renewable energy. Read More

Loss-free Solar Heat Battery

Solar Heat Battery

A chemical reaction transfers the absorbed heat into a special system, where it is stored. This system consists of a container that is mostly filled with salt, and a little water.

Until now, solar heat couldn’t be stored without several loss.

But this is gonna change. 

TNO presents a battery which can be used for solar heat storage without losses.

The heat is held in the salt, and the chemical reaction that trapped it there is reversed to release the heat again when it is needed. ‘It’s all about hydration and dehydration, or wetting and drying salt.

Energy producing buildings

TNO succeeded in developing a solution to store the energy surplus of energy producing buildings in a working lossless heat battery. Read More

Can Hydrogen compete E-cars?

Can Hydrogen Cars compete with E-cars?

In the body of the study it becomes clear that FCVs do not beat internal combustion engines (ICEs) by much in equivalent fuel economy, And they are not much better in greenhouse gas emissions either, particularly in the liquid hydrogen versions, because of the energy required to transport and compress the hydrogen.

Hydrogen fuel cell cars appear to be making a comeback. But is this real? The comparison in question includes discussion of:

  • the wider process behind producing hydrogen fuel
  • the production itself
  • the compression/storage
  • the transportation of the fuel
  • associated factors

The future is a bit cloudy for hydrogen fuel cells (HFC), as electric vehicles have developed quickly and taken significant market share. Read More
