6 FAQs about [Hollow concrete sphere solar container]

Could concrete storage spheres be dropped down to the oceans?

In an effort to reduce the use of precious land to build renewable energy storage facilities, the Fraunhofer Institute has been cooking up a wild but plausible idea: dropping concrete storage spheres down to the depths of our oceans.

Could concrete spheres be a sea-based alternative to land-hungry energy storage?

That’s exactly what researchers at Germany’s Fraunhofer Institute are exploring, with plans underway to submerge massive concrete spheres in the ocean, offering a sea-based alternative to land-hungry energy storage solutions.

Could hollow concrete spheres sunk a new frontier?

Since 2011, the team has focused on deploying giant hollow concrete spheres sunk hundreds of feet beneath the ocean surface to test the waters on this new frontier, according to a report on New Atlas. An empty sphere functions as a fully charged storage unit.

How can concrete spheres sunk deep in oceans help reduce land use?

We empower professionals with advanced engineering and tech education to grow careers. We recognize outstanding achievements in engineering, innovation, and technology. Concrete spheres sunk deep in oceans may store renewable energy at scale, offering a new solution to reduce land use.

How does an empty sphere work?

An empty sphere functions as a fully charged storage unit. When its valve opens, seawater flows inside, driving a turbine connected to a generator that feeds electricity into the grid. To recharge, water is pumped back out against the surrounding pressure using energy from the grid.

How does a water sphere work?

To recharge the sphere, water is pumped out of it against the surrounding water pressure using energy from the grid. Each hollow concrete sphere measures 30 ft (9 m) in diameter, weighs 400 tons, and will be anchored to the sea floor at depths of 1,970 - 2,625 ft (600 - 800 m) for optimal performance.
