Revolutionize Energy Efficiency

Waste heat recovery as an innovative way to reduce emissions

By Adi Voldman, Head of Waste Heat Recovery activity


Ormat Technologies is a leading global provider of renewable energy solutions, specializing in the development, manufacture, and deployment of geothermal power plants and recovered energy generation (REG) systems. One of Ormat's most innovative and successful technologies is our REG systems, which have revolutionized the way industrial facilities reduce their carbon footprint.


At its core, Ormat's REG technology captures waste heat from industrial processes and converts it into clean, renewable electricity. This technology is a game-changer for industries that produce large amounts of waste heat, such as cement, steel, chemical plants and any facility that generate heat such as gas compressor stations. In the past, this waste heat was simply released into the atmosphere, contributing to greenhouse gas emissions and wasting valuable energy. With Ormat's REG systems, however, this waste heat is harnessed and used to generate electricity, thereby reducing emissions, significantly improve overall energy efficiency, lead to substantial cost savings and providing a reliable source of power.


Ormat's REG system captures waste heat to heat the Organic working fluid (directly, or through intermediate heat media). The heated working fluid vaporizes and expands in a turbine, which is connected to a generator that produces electricity. The working fluid is then cooled and recycled back into the system, where it can be used again to generate more electricity.

Ormat's REG systems are highly customizable, with solutions tailored to meet the specific needs of each customer and are designed to generate electricity from a wide range of waste heat sources and operating conditions. The systems are also designed to be highly efficient, with low maintenance requirements and long operating lives.


In addition to the environmental and economic benefits, Ormat's REG systems also offer important reliability benefits. By generating electricity on-site, industrial facilities can reduce reliance on the grid and ensure a stable source of power even in the event of power outages or other disruptions.


Overall, Ormat's REG technology is an important part of our commitment to providing sustainable, reliable, and innovative energy solutions. As more and more industries look for ways to reduce their carbon footprint and increase their energy efficiency, Ormat's REG systems are poised to play an increasingly important role in the transition to a cleaner, more sustainable energy future.
