ERV is a venture capital fund focused specifically on electrochemical and new chemistry businesses—covering energy storage, hydrogen, carbon capture, and advanced materials—rather than broader climate tech, and it also runs Prosemino, a venture builder with its own wet and dry lab space in London to help develop these technologies. Its portfolio centers on core industrial building blocks like batteries, hydrogen membranes, and carbon capture materials, and it is backed by industrial-focused investors, including family offices in metals and energy and the CVC arm of Morocco's OCP Group.
