“Heat Recovery Steam Generator (HRSG) Market Set to Reach USD 2.4 Billion by 2030: Trends, Drivers, and Strategic Insights”
Introduction
In the race towards energy efficiency and decarbonization, Heat Recovery Steam Generators (HRSGs) have emerged as essential assets in modern power plants and industrial facilities. As global energy demands rise, so does the need for systems that maximize output while minimizing waste. Enter the HRSG — a powerful solution that captures exhaust heat from gas turbines to produce steam, reducing fuel consumption and greenhouse gas emissions.
Valued at USD 1.6 billion in 2023, the global HRSG Market is projected to grow at a CAGR of 6.1%, reaching nearly USD 2.4 billion by 2030. This article explores what’s driving that growth, the challenges and opportunities ahead, and what key players and investors need to know.
What is a Heat Recovery Steam Generator?
A Heat Recovery Steam Generator is a type of energy recovery heat exchanger that recovers heat from hot gas streams — typically the exhaust of a gas turbine — and uses it to generate steam. This steam can then be used in combined cycle power plants or for industrial processes, increasing overall efficiency and reducing emissions.
