To store 1 MWh of energy, you''re storing 3.6 billion joules of energy - 3.6e+9 J. From the article they''ve got a fall of 550m, so to store 1 MWh you need 667,903 kg of material - 667 tons, so probably about 333 cubic meters of volume.
Concrete with smart and functional properties (e.g., self-sensing, self-healing, and energy harvesting) represents a transformative direction in the field of construction materials. Energy-harvesting concrete has the capability to store or convert the ambient energy (e.g., light, thermal, and mechanical energy) for feasible uses,
By David L. Chandle, Massachusetts Institute of Technology October 4, 2023. MIT engineers have created a "supercapacitor" made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive

Several thermal energy storage (TES) systems have been developed and tested to be integrated in concentrating solar power (CSP) systems. Recent studies show that concrete as storage media has the potential to become an interesting solution due to its properties such as relatively high specific heat and thermal conductivity, good
They estimate that a 45 cubic meter sample of their supercapacitor could hold 10 kilowatt-hours of energy—equivalent to about one-third of an average U.S. household''s daily electricity usage.
Abstract. The performance of a lab-scale concrete thermal energy storage (TES) module with a 2-kWh thermal capacity is evaluated at temperatures up to 400 °C. The TES module uses conventional normal weight concrete with thermal and mechanical properties that are tailored for use as a solid thermal energy storage media.
By storing excess thermal energy during periods of low demand or high energy production, concrete matrix heat storage systems contribute to energy efficiency and load balancing in the energy grid. This allows for the efficient utilisation of renewable

We characterize our carbon-cement electrodes by combining correlative EDS
The world is undergoing an energy transition with the inclusion of intermittent sources of energy in the grid. These variable renewable energy sources require energy storage solutions to be integrated smoothly over different time steps. In the near future, batteries can provide short-term storage solutions and pumped-hydro storage

In summary, our material design of porous carbon-cement composites provides a scalable material solution for energy storage to support the urgent transition from fossil fuels to renewable energies. Key to scalability is the intensive nature of the volumetric capacitance, which originates from the unique texture of the space-filling carbon network.
Concrete is perhaps the most commonly used building material in the world. With a bit of tweaking, it could help to power our homes too. It means that we need to store that energy in batteries

Electrical energy storage (EES) alternatives for storing energy in a grid scale are typically batteries and pumped-hydro storage (PHS). Batteries benefit from ever-decreasing capital costs [14] and will probably offer an affordable solution for storing energy for daily energy variations or provide ancillary services [15], [16], [17], [18].
Ulm says that the system is very scalable, as the energy-storage capacity is a direct function of the volume of the electrodes. "You can go from 1-millimeter-thick electrodes to 1-meter-thick electrodes, and by doing so basically you can scale the energy storage capacity from lighting an LED for a few seconds, to powering a whole house," he
