Lithium batteries could count days to store solar and wind energy
The society behind this battery is Climate change technologies, also called CCT energy storage. The battery, which they named TED (thermal energy device), is a modular storage system to store the energy generated by any type of source, whether solar, wind or fossil. This is very useful because solar energy can not be used at night and it is necessary to have batteries to be able to store and use it during these hours.
The key to this battery is that it uses heat for heat and melt silicon It is stored inside by means of an isolated camera. Each of these batteries can store 1.2 MWh of energy, with a compact design that can be placed in a transport container of 6 meters.
So, in this size, he is able to store 12 times more energy than a lead-acid battery, and around 6 times more than a lithium. In addition, it is very easily scalable and is therefore ideally suited for storing excess energy generated by renewable energy systems ranging from 5 kilowatts to virtually any capacity. They are also useful against power outages because they can stay active for 48 hours in a row.
They last almost 10 times longer than those of lithium and are 100% recyclable.
Another interesting part of the thermal batteries they can be loaded and unloaded at the same time, in addition to having virtually no maintenance. Its durability far exceeds that of lithium batteries, where they reach up to 3000 charge cycles without degradationand they only go down to 80% with 5,000 charge cycles. In the case of lithium, it is normally reached Load capacity of 80% when they take about 700 cycles. With this, each The battery can last up to 20 years.
The key to this durability is the material used. Molten silicon, used in thermal batteries, requires only a phase transition by heat application. In addition, when the end of life is reached, the battery is discharged. 100% recyclable, compared to lithium and its associated problems. A shutdown system can also be installed in the face of earthquakes, where it can be disabled. It is not advisable that there is silicon to 1400 degrees Celsius it can spread.
In addition, the key that will facilitate the implementation of these batteries is that its cost is between 60 and 80% of the price paid for a battery such as the Tesla Powerpack, in addition to occupy less space.
The company has already signed agreements with companies such as Stillmark Telecommunications or the group MIBA who will be able to manufacture and market the batteries in Denmark, Sweden and the Netherlands, in addition to other European countries which will soon be added to the list and are currently in the negotiation phase.
The first business units will be manufactured during this second quarter with 10 units and once they start to gain market sales, they will increase their production to create more than 100 MW installations. here two years with more than 200 units. Although these batteries are better suited to power grids, they will not reach mobile phones or cars for all the necessary associated technologies, such as container, insulation, heat generation engine, etc.
