Israel has pioneered technologies that recover energy from water infrastructure. One notable example is InPipe Energy (operating internationally) and Israeli-developed in-pipe hydropower systems that capture excess pressure inside municipal water pipelines.
Water distribution systems often use pressure-reducing valves (PRVs) to prevent pipe damage. Instead of wasting this pressure, specially designed turbines can be installed inside pipes to convert kinetic energy into electricity. These systems typically generate power ranging from a few kilowatts up to hundreds of kilowatts, depending on flow rate and pressure.
Israel’s water sector is highly advanced due to its arid climate and large-scale desalination infrastructure. Integrating micro-hydropower into pipelines increases overall efficiency without requiring dams or additional water diversion.
While these systems do not produce large-scale grid power like hydroelectric dams, they provide localized renewable energy and reduce operational costs. It’s an example of smart infrastructure — extracting energy from systems already in operation.
