Technologie de stockage de l’énergie, après Rondo le projet soutenu par Bill Gates à base de brique capable de restituer en énergie une t° « stockée » de 1500°, une nouvelle technologie « carbone » pète le score à 2000° (température de fusion 3000° = 2 x l’acier)

As a waste product of several other industrial processes and a common input to the metals industry, these blocks are available in virtually unlimited quantities, through well established supply chains
“Among the least expensive bulk thermal storage materials available,” with a materials cost around US$1/kWh – about 50 times cheaper than lithium-ion batteries
They’re non-toxic, conflict-free, and cause no environmental issues in solid form
High thermal conductivity, and high mechanical strength that increases as it gets hotter, gives solid carbon the ability to rapidly absorb large amounts of energy
The blocks remain solid at upwards of 3,000 °C (5,432 °F), roughly twice the temperature at which steel melts, sidestepping many issues found with molten salts, and other liquid heat storage media
High energy density makes these carbon blocks easy to transport, and gives Antora’s heat batteries a small footprint on site
They’re compatible with ultra-high temperature applications
