Earth’s gravity: the largest (and inexhaustible) source of clean energy

On November 15, 2022, the world population reached 8 billion people.

Even if each of us were to use judiciously use the resources of our planet, avoiding waste and implementing virtuous behaviourour energy needs is inevitably destined to increase dramatically. To this must be added the ever more pressing need to find green and reliable sources of supplycapable of providing energy continuity to the grid.

And if on this aspect solar and wind are proving to be fragile, geothermal and gravity proved absolutely solidacting not only as a provider but also as an accumulator.

Among the companies that are perfecting systems for the exploitation of gravity for energy purposes, we find the Swiss Energy Vault which has developed a sophisticated automated 35 ton gravity block stacking and unstacking system in an open space with a 70-meter-high six-arm crane.

In this circuit the potential energy increases as the objects or blocks rise, decreasing as the bodies lower.

Energy Vault’s method is more sustainable than other dam-based storage systems (such as that of Nant de Drance, located in the Canton of Valais, which we talked about in this article), on gigantic batteries or on other materials, as in the case of Enel’s thermal storage.

After developing a successful prototype in 2020, the company is now aiming to build 20-story buildings “Energy Vault Resiliency Centers”.

Other companies, such as Gravitricity, they stack weights of 500 to 5,000 tons in a mine shaftwhile New Energy Let’s Go and Gravity Power each have individual stacking methods that they use water hydraulics.

Research into safe and performing storage systems it is almost more important than the one dedicated to the exploitation of renewable sources.

According to the latest estimates, approx 13% of the world’s population lives in energy poverty, i.e. 940 million people lack access to electricity.

A data doomed to increase not just because of increasingly violent and frequent atmospheric events due to climate change, which by destroying entire communities leave the survivors without a functioning electricity network, but also as a result of wars.

According to HuffingtonPost, Ukraine, which has been under Russian military attack since February 24, he has been in serious energy difficulties for ten days.

President Zelensky, during the daily evening message to the population, reported the invitationby the national energy companies, currently engaged in repairing the damage suffered by the grid, to consider leaving the country to reduce electricity demand.

“If they can find an alternative place to stay for another 3 or 4 months, it will be very helpful for the system [ndr elettrico]…”the CEO of told the BBC Dtekthe main electricity provider in Ukraine, Maxim Timchenko. “… If less is consumed, hospitals with injured soldiers will have guaranteed power supply”has explained.
