The group's storage solution is especially suitable in places like Switzerland, where solar power is abundant in the summer, and scarce in the winter. Surplus solar power is used to split water to produce hydrogen in the summer; it's then streamed into stainless steel reactors filled with iron ore at 752 °F (400 °C).

The cleanest way to produce hydrogen is by using sunlight to directly split water into hydrogen and oxygen. Multijunction cell technology developed by the photovoltaic industry is being used for photoelectrochemical (PEC) light harvesting systems that generate sufficient voltage to split water and are stable in a water/electrolyte environment.

is a storage form whereby hydrogen gas is kept under pressures to increase the storage density. Compressed hydrogen in hydrogen tanks at 350 bar (5,000 psi) and 700 bar (10,000 psi) are used for hydrogen tank systems in vehicles, based on type IV carbon-composite technology. Car manufacturers including Honda and Nissan have been developing this solution.

Among the many hydrogen-storage materials reported, transition-metal hydrides can reversibly absorb and desorb hydrogen, and have thus attracted much interest from fundamental science to applications. In particular, the Pd-H system is a simple and classical metal-hydrogen system, providing a platform suitable for a thorough understanding of .

“Fundamentally, the aluminum becomes a mechanism for storing hydrogen—and a very effective one,” says Douglas P. Hart, professor of mechanical engineering. “Using aluminum as our source, we can ‘store’ hydrogen at a density that’s 10 times greater than if we just store it as a compressed gas.”

Companies internationally are working to produce hydrogen without the carbon output, and in quantities large enough to serve global energy needs to allow us to start relying on it. According to GlobalData, global green hydrogen production capacity reached over 109,000 tonnes per annum (ktpa) in 2022, representing a 44% increase over 2021.

A tower of the concrete blocks — weighing 35 metric tons each — can store a maximum of 20 megawatt-hours (MWh), which Energy Vault says is enough to power 2,000 Swiss homes for an entire day. According to Quartz, the Swiss startup is planning to build their first commercial plants starting early 2019.
