Business Model
What each company does and how it makes money
NuScale Power designs and sells small modular nuclear reactors for electricity generation and industrial heat applications. It generates revenue primarily through engineering, procurement, and construction contracts for its modular reactor systems, with future recurring revenue expected from long-term service agreements. The company's key advantage is its proprietary, passively safe reactor design — which is smaller, scalable, and factory-built — offering a standardized nuclear solution with lower upfront capital requirements than traditional large-scale plants.
Brenmiller Energy develops and sells thermal energy storage systems that use crushed volcanic rock to store heat at high temperatures for industrial and utility applications. The company generates revenue primarily from selling its proprietary bGen TES systems and related services to industrial customers and power producers. Its key advantage lies in the proprietary rock-based storage technology — which offers durability, scalability, and the ability to provide dispatchable heat or steam on demand using low-cost materials.
