it is literally rock science ;)
Seriously, in Germany, concrete costs arount 100 EUR per cubic meter. So we would end up with around 150 EUR per kwh capacity. But they would not have to use concrete for the task. They could as well use 23 m^3 gravel (which goes down to 10EUR) and some steel scaffolding. Or even just plain water (35m^3).
- vidarh 6y agoThey're using "composite" bricks that include waste material (I can't find any obvious references to exactly what kind of mix of materials), so my guess would be the material cost will be rather low.
