hi guys welcome back to elon musk evolution friends have you heard about a sand battery
it is a step forward to a better safer greener future today we will share some very important
information about sand batteries hope you will be benefited make sure to stick to the end of this
video as we have a lot to cover also don't forget to subscribe to our channel and like today's video
it helps us a long way what is a sand battery according to musk it is an electrochemical battery
with a wet sand electrolyte british and irish magnetic telegraph company were the first ones to
use these batteries and found them quite effective the sand battery charges low quality sand with
the heat made from relatively low-cost solar or wind-generated electricity it can store heat at
approximately 500 degrees celsius retaining it for months to keep homes warm in winter
can we produce electricity from sand yes we can and the outcome is amazing first the sand is
heated by running cold sand through a solar heat collector here it is heated before it is stored
in a hot reservoir this hot sand is now ready to be used to run electricity generating turbines the
cycle is completed by returning the cooler sand to the upper cold sand reservoir sand can store a lot
of heat in a small space at a temperature of about five to six hundred degrees celsius and is a tough
affordable material the heat storage has an eight megawatt hour energy capacity and one hundred
kilowatts of heating power when you think of energy solutions you are reducing your burden on
fossil fuels which are depleting at a high ratio engineers are working to produce devices that are
not only cost effective but are environmentally friendly as well scientists are optimistic that
sand batteries can be a good solution to the fossil fuel crisis how does a sand battery work
musk in an interview stated that polar night energy has developed a unique way to store heat
several hundred tons of sand are filled within a four by seven meter steel container
the sand is then heated using solar or wind energy stored and used to heat the neighborhood
by a local energy supplier in essence it is a huge sand battery remember wind and solar energy
are extremely useful and inexpensive but they do not ensure a continuous supply of energy whereas
sand is long lasting and budget friendly and can store a lot of heat without dissipation
at a temperature of about five to six hundred degrees celsius this means that once heated
the silo can stay hot for months with the least intervention more specifically the system has
an eight megawatt hour total energy capacity and a maximum heat power discharge of 100 kilowatts
the sand can be heated up to a thousand degrees celsius or even higher inside the sand is an
insulated heat transfer system to eradicate heat loss and carrier to and from storage
currently the company's sand battery is heating the can kanpa neighborhood keeping the
neighborhood's homes workplaces factories schools and swimming pools warm we were talking about how
if we had the liberty to design a community for ourselves how could we solve the energy problem
in such a confined environment marcus speaks about the ambitious approach of the company
he added then quite quickly especially here in the north you run into the problem of energy storage
if you're trying to produce the energy as cleanly as possible are sand batteries commercially
attainable in finland polar night energy has created the first commercial sand-based heat
storage battery system which might provide a way to sustainably supply heat and electricity
throughout the year by converting electricity to heat and storing it for later use battery
technology improves solar and wind energy the technology might help finland address the rising
cost of fossil fuels and support the government's commitment to achieving a net zero economy to the
2015 paris agreement's climate change goals musk explained vatinjenkowski power plant an energy
utility in western finland the new technology has been introduced by young finnish engineers
tommy ironin and marcu yolonen founders of polar night energy they have assured that it could be
used worldwide the first sand battery device has been installed in vatijankowski power plant an
energy utility in western finland experts say that it will provide heat for vata jankowski's heating
network in can kanpa in 2022 it has storage for 100 kilowatt heating power and a capacity
of 8 megawatt hours solar energy stored in sand batteries could help get fins through the long
cold winter which is said to be even tougher after russia stopped its gas and electricity supplies
additionally polar night energy is conducting a test pilot in hedenronta tampir where it is
heating a few buildings to evaluate verify and improve the sand battery solution
a 100 square meter solar panel system and some grid electricity are used in the pilot project
to help the project get off the ground the council donated the space to provide the funding
what are the major growth drivers of the world market for sand batteries according to musk an
increase in the use of smartphones computers and other electronic devices like power banks
remote controls and tablets are major growth drivers of the world market for sand batteries
the expected lifespan of silicon-based electric vehicle batteries can be increased by up to three
times or more with the use of sand batteries which can also improve performance according
to estimates this will help electric vehicle owners since batteries can be pricey to replace
as a result it is anticipated that the global market for sand batteries will grow during the
forecast period since sand batteries are safe for the environment and non-toxic it is anticipated
that increased awareness of energy conservation will benefit the global sand battery market during
the forecast period after receiving 70 million dollars usn funding from sutter hill ventures
in 2018 to develop and produce materials for a new standard of batteries as well as an additional 170
million dollars led by daimler in 2019 scila nano technologies inc is a significant player in the
global sand battery market after test pilots are finished and the performance of the vatijankowski
power plant has been independently peer reviewed more investment is likely to be attracted by the
capacity of polar night energy's sand battery technology to heat buildings climate change sand
battery could solve green energy's big problem friends hope we thoroughly explain the mechanism
of the sand battery finland as an example is trying to expand its production and export
now let's talk about the most crucial element of sand batteries can they solve green energy's
major problem and the big answer is a big yes the developers say this could solve the problem
of year-round supply a major issue for green energy we are experiencing drastic changes
in climate and environmental scientists fear by 2030 our planet will be in a vulnerable condition
the rapidly rising price of fossil fuels is another reason there is a ripple in investment
in new renewable energy production while new solar panels and wind turbines can be added to
national grids these extra sources also present huge challenges the large battery installed at
the vatijan koski power plant uses sand from a nearby sand pit we wanted to find something
that can be sourced nearly everywhere in the world the 33 year old explained but is sand as
ubiquitous as we might think according to a dutch study released earlier this year demand for the
building material will increase by 45 percent over the next 40 years sand pirates are hastening the
loss of building sand from these ecosystem which are typically taken from rivers and lakes for
construction purposes but it doesn't really sand comes from in the eyes of the finnish engineers
sand batteries can be used with any material that has a high enough density as long as it
falls within certain thermodynamic constraints even though the prototype used builder sand to
reduce transportation emissions we don't want to compete with the construction industry for
the good qualities of sand marco affirms in close reality the focus is less on the sand
and all about helping the wind and solar sectors to grow he adds we think that this is just one of
the key components to make a society with a high production of wind and solar power
given the delicate geopolitical balance in finland and the pressing need for the world to transition
away from fossil fuels it is not surprising that interest in polar night energy has soared
after a huge success in tampere the company made lots of inquiries about building apparatuses
before winter in the winter season the demand for heating buildings increases on a large scale
their ambition extends well beyond western finland proposes marku we want to build a
hundred times larger storage around the world as fast as possible a small finished startup
of six people has developed an intriguing and affordable solution the world's first commercial
heat storage battery made of a very low-tech low-cost material the district heating system
which is a neighborhood network of insulated pipes will be used to distribute the heat from
the silo which is a relatively small silo and a pilot project for vatinjin koski plant's managing
director pekka passi simply adores contemporary technology he hopes that in near future this
new technology will be seen operative in 10 plus countries nationwide they are optimistic
that there will be a tremendous decrease in environmental pollution please leave a comment
