In a rip-off truck in West Orange, New Jersey (EE.UU.), an electric car passes by one of the transits, which are completely missing from the space that is inside.
The car is parked at double the speed that the most conventional vehicles, giving the powder of the calf that, tal vez, the hizo cosquillas in the nariz to the cabalos that tiraban the cars.
Era principios del siglo XX and the conductor of the specific car era Thomas Edison.
If the electric cars are not a novelty in the nursery, the majority of them depend on the weight and volume of plum and acid batteries.
Edison has his car equipped with a new type of battery and hope that soon all the vehicles of all the country will use: era una nickel-iron battery.
About the base of the work of the uitvinder Swedish Ernst Waldemar Jungner, who first patented a nickel-iron battery in 1899, Edison refined it for his use in cars.
The established manufacturer claims that the nickel-iron battery is incredibly resistant and can load the most fast plumbing and acid batteries.
Includes an agreement with Ford Motors to produce this most efficient electric vehicle.
But the nickel-iron battery has some problems.
It’s great that plum batteries and acid that are usable and also are more expensive.
Además, cuando se cargaba, liberaba hydrogen, which at the moment is considered a preoccupation and can be dangerous.
Unfortunately, at the time Edison was building a more refined prototype, the electric vehicles were disappearing and the cars were being propelled by terrestrial fossil fuels, and the podiums would cover longer distances than ten.
The Edison contract with Ford Motors has been unveiled, although its battery continues to be used in some niches such as the railroad car, where its bulky tire is not an obstacle.
More than one sail sailed, the engineers rediscover the nickel-iron battery as a gross diamond species.
Now it is being studied as a response to the permanent challenge of generating renewable energies and complementing the sources of energy like electricity and solar.
And the hydrogen, which some consider considered preoccupied, can be converted into one of the most useful elements of these batteries.
Electrolysis
In the middle of the decade of 2010, a research team from the Delft University of Technology in the United States discovered a use of a nickel-iron battery based on hydrogen produced.
When electricity passes through the batteries the mine is charged, suffers from a chemical reaction that releases hydrogen and oxygen.
The reconstitution team that reacts with the water is used to release hydrogen, known as electrolysis.
“I understand that chemistry was the mism”, double Fokko Mulder, leader of the research team of the University of Delft.
This water division reaction is a form in which it produces hydrogen for its use as combustible and completely limping, while the energy used to stimulate the reaction is from one fuente opknapbaar.
If Mulder and his team know that the electrodes of the nickel-iron battery are capable of dividing the water, they will be surprised to see that the electrodes start to have an energy-boosting mayor that produces hydrogen.
In other words, convert to a better battery when also used as an electrolyzer.
It is also important to note that electrodes resist electrolysis, which can significantly degrade the most traditional batteries.
“And, by the way, we are pleased that energy efficiency appears to be good throughout this year”, doubled Mulder, increasing levels from 80% to 90%.
Mulder number to its creation el “artery” and hopes that the discovery can help to resolve important challenges for renewable energy: the release of energy and, when the batteries are empty, the production of combustible limpio.
“Listen to arguments about batteries, for a charge and hydrogen, for another”, Mulder doubles. “Always have a species of competence between the two, but basically need both”, added.
Renovable value
One of the most challenging mayors of renewable energy sources like the eolica and solar is the unpredictable and intermittent that can be.
With the solar, for example, it produces an energy surplus during the day and the day, but during the night and during the winter months, the summit decreases.
Conventional batteries, like the bases in lithium, can charge energy in short space, but when fully charged they have to release any excess sovereignty and degrade.
Without embargo, the “battolyser” of nickel-iron is permanently stable when fully charged, at which point it can be produced to produce hydrogen.
“(The nickel-iron batteries) are resistant and can tolerate the insufficient load and the better load than other batteries“, dice John Barton, researcher associate of the School of Mechanical Engineering, Electrical and Manufacturing of the University of Loughborough and United Kingdom, who also invested in the” battolyser “.
“With the production of hydrogen, the ‘battolyser’ collects energy from different days and includes between stations” of this year, year.
In addition to creating hydrogen, nickel-iron batteries also have other useful features.
First lie, which requires a exceptionally low maintenance. Son extremely durable, like the Edison demonstration in its first electric car and knows that some of them for more than 40 years.
The metals needed to make the battery (nickel and iron) are also more common than, for example, the cobalt used to create conventional batteries.
This means that the “battolyser” could have another paper for renewable energy: help it más rentable.
As any other industry, the prices of renewable energy fluctuate following the offer and the demand.
In a brilliant and solemn day you can have a large amount of solar energy, which can provoke an excess and a cycle in the price by which you can sell the energy.
The “battolyser” could help save these fluctuations.
“When electricity prices are high, you can charge this battery, but when electricity price is low, you can charge the battery and produce hydrogen,” says Mulder.
The “battolyser” is not alone in this aspect.
The most traditional alkali electrolyzers equipped with batteries can also perform this function and there are many extenders in the hydrogen production industry.
Mulder cree that the “battolyser” can do the same for less money and for more time thanks to the durability of the system. It’s something that is giving hope to the partisans of the new discovery.
Although hydrogen is the direct product of “battolyser”, it can also generate other useful substances, such as ammonia or methanol, which make it easier to transport and transport.
“With a ‘battolyser’ installed, (a) ammonia plant will operate in a more constant manner and (necessary) less maneuvering, which will reduce operating costs and maintenance costs”, dobbeltsteen Hans Vrijenhoef, executive director of Proton Ventures, que investment in Mulder’s “battolyser”.
“Asia produces ammonia in the most fertile, sustainable and ecological way”, added.
Escalando
At the moment, the largest “battolyser” that exists is 15 kW / 15 kW and has sufficient battery and hydrogen hydrogen storage capacity for a large space to feed 1.5 ounces.
It is working on a larger version of a “battolyser” of 30 kW / 30 kW h in the Magnum power plant in Eemshaven in the Netherlands, which will have sufficient hydrogen to satisfy the needs of the plant.
Once upon a time there were some rigorous tests, the object is todistribute and distribute the “battolyser” to green energy producers, as well as solar and eolicos parks.
Ultimately, the defenders of the “battolyser” hope to launch a gigabyte scale equivalent to the energy generated by an average of 400 eel turbines and a scale of public services.
In addition to the amplification, Barton has a paper for the “small battolyser” that could help save energy on the mini-devices used by remote communities that are not part of the main electrical devices.
The hecho of which the electrodes of the “battolyser” are hechos of common metals and relatively baratos can help.
And unlike the lithium, the nickel and the iron do not generate large amounts of water decoction when extraened, they are associated with a significant ambient degradation.
As such, both Mulder and Barton have obstacles that surpass in terms of efficiency and capacity.
“The ‘battolyser’ benefits greatly from a mayor’s capacity as a battery or from reduced internal resistance,” Barton doubled.
Internal resistance is the opposition to the current currant in a battery. When the mayor has internal resistance, the efficiency will be less. Mejorar eso is algo in that Mulder and his team are working.
Much of the potential of the “battolyser” has been in full view since Thomas Edison began experimenting with his nickel-iron battery on the principles of sail XX.
It is possible that he was equipped to create his own battery with the other vehicles on the roads.
Pero the nickel-iron battery can dissipate a paper on the replacement of the fossil fuels in general, it will help accelerate the transition to renewable energy.
