To store the increasing amount of clean energy coming from renewables, we need batteries. Without them, there’s a risk of stalling the transition away from fossil fuels. Stationary thermal batteries or heat batteries are growing in popularity for industrial processes and district heating. In this episode of Transforming Business, we look at some simple, natural, and cost-effective materials, squirreling away energy as heat to be used when needed.

Do you remember walking on the midday beach sand under 30º C? It will burn your feet. That's what is enough…
Finland is a wealthy country. The resources required to create this huge battery are immense. Fossil fuels are used to create and run the materials and machines required to create this magical battery. This is not a solution. This is not a panacea. This is not “renewable”.
Nice and informative. Best way to the planet carbon neutral in less than 20 years may be 10 years and at a reasonable cost
Would love to know more on this subject

Generating electricity using photovoltaics only to convert it resistively into heat is a horribly inefficient way of using energy. A much better way would be to convert sunlight directly into heat using lenses etc to directly 'charge' the thermal battery.
This is why I love YouTube.
In Canada, the use the sand battery to store the heat when the summer, and uses the heat to warming up the building when winter
Excellent future
Sand battery, flow Battery, Aluminum air battery, flywheel power storage
Can we at least hear a vague reference how much watt or joules can be stored? Some hard figures. I hear only marketing-like statements "equivalent of a Tesla", yeah, which Tesla? So vague. Please do the effort to explain what watt-hour is and use real units. Celcius doesn't count, it doesn't indicate how much energy is in it. This is too wooly and not convincing for me.
An interesting, well presented and balanced video, thanks for sharing

Where is the innovation ? UK has been using storage heaters in homes (using bricks and off peak electricity foe decades. reinventing the wheel ?
Willen jullie de hele natuur vol met opslag zetten Weten jullie wel dat dat heel veel plaats nodig heeft.Weer niet over nagedacht.Zet er ook nog een paar datacenters neer dan gaat iedeeen dood,want dan hebben die datacenters al ons water nodig.Denk eens na.Niet te geloven
Let's always do alot of good
Congrats, you "discovered" the principle behind the terracotta stove which many east-european houses still use in rural areas today to heat their homes using firewood during winter.
Not saying it's a bad idea but the half tone brick is exactly like a terracota stove, storing heat and gradually releasing it into the shorounding environment.
I don't se the revolution here. Degrading electricity to heat doesn't help with our renewable storage problem at all.
Interesting calculation:
1) The silo of 4 meter wide and 7 meter hight has 220 tons of sand (with perfect conditions, without insulations and any other equipment). Once heated to 600 celsius degrees it will store about 112 gigajoule of energy.
2) The swimming pool (mentioned in the video) of 25 meter long and presumably 15 meter wide and 1.5 meter deep will have 565 tons of water. It will need 2.4 gigajoule of energy to heat this water by 1 celsius degree.
3) Thus, in perfect conditions (there is no energy loss anywhere) this silo will allow to heat the water in the pool by 50 celsius degree for once. Or, imagine that it will be used to maintain the temperature of water. Suppose the water in the pool loose 1 celsius degree per 1 hour, the silo will allow to maintain the temperature in the pool for only 2 days, in perfect conditions (so, in real conditions it will be not more than 1 day). Not much!
I had to listen to 2:00 three times, as I couldn't believe my ears – "The sand stores electricity".
No wonder the west is falling behind when even large, govt. sponsored media outlets are so clueless about what they are talking about.
Absolute hogwash. Another technique to plunder the taxpayers.
Could the leftover cement from demolish buildings or the waste after burning trash for electricity be used as energy storage medium?
30% energy loss is serious. They also don't mention the cost and maintenance of the installation to turn electricity into heat and, more importantly, to turn heat into electricity. Still nice to see they are working on these problems!
If you put an iron scouring pad in a pyrex tube filled with water,the sun will keep boiling water because 0 heat can escape pyrex tubes.if someone can invent a more efficient conductor of sun heat,there will be a new very high efficiency battery storage combination that no one has realised yet.
Salt heat batteries are interesting ,but humidity batteries are genius,thanks for this educational documentary,encouraging future
Early stage (up to 5 years):
Adoption of new technologies takes time, so adoption is expected to be low (e.g., less than 5%).
Mid-term stage (up to 10 years):
As technologies mature and costs fall, adoption may increase (e.g., around 20%).
Long-term stage (up to 20 years):
With improved policy support and infrastructure, adoption may increase (e.g., 50% or more).
