Business Model
What each company does and how it makes money
Rain Enhancement Technologies Holdco develops and commercializes ionization technology to artificially generate rainfall for governments, industries, and regions facing water scarcity. It makes money primarily through technology licensing agreements and project implementation contracts with clients — typically governments and large agricultural or industrial users — seeking to augment their water supply. The company's moat lies in its proprietary ionization rainfall generation technology and first-mover advantage in a niche but growing climate adaptation market.
Energy Vault develops gravity-based energy storage systems that use custom bricks and cranes to store and release electricity. The company makes money primarily through selling its EVx gravity storage platforms and related software solutions to utilities and large energy users. Its key advantage is proprietary gravity storage technology that offers longer duration storage—up to 24 hours—compared to lithium-ion batteries, using low-cost materials like soil and waste materials.
