Researchers from the Massachusetts Institute of Technology (MIT) have harnessed two of the world''s most ubiquitous materials, concrete and carbon black, to develop a novel
A startup called Energy Vault is working on a unique storage method, and they must be on the right track, because they just received over $100 million in Series C funding last week. The method was inspired by pumped hydro, which has been around since the 1920s and uses surplus generating capacity to pump water up into a reservoir.
