Steam & electricity generation segment accounts for the largest share in WHRS market
The WHRS market is segmented based on application into preheating, steam & electricity generation, and others. In 2015, the steam & electricity generation application segment captured the maximum share of the overall market; it is also expected to witness the highest CAGR during the forecast period. Steam & electricity generation is a significant application of the recovered waste heat because of the growing demand for energy in both developed and developing economies. Steam generation from waste heat sources is crucial to several end-use industries and, hence, is a major WHRS application.
Growing demand from the cement industry to boost the WHR system market
The major end-use industries of the WHR system are petroleum refining, metal production, cement, chemical, paper & pulp, and others. The demand for WHRS in the cement industry is projected to register the highest CAGR during the forecast period. The global cement industry is projected to register a CAGR of 9%. The growth in this industry is backed by increasing investments in various developing countries worldwide, increasing per capita income, and economic growth. The construction sector of developing countries such as China, India, and Indonesia is growing rapidly, especially in terms of social and education, healthcare, retail, and residential construction. These factors will also play a crucial role in driving the demand for WHRS in the cement industry.
Europe: The largest market in WHRS
The WHR system market is broadly segmented into five regions, namely, North America, Europe, Asia-Pacific, the Middle East & Africa, and South America. Europe is the largest WHR system market, closely followed by North America, in terms of value. Government and environmental organizations in various countries such as the U.S. and European Union have adopted stringent legislations on energy saving and energy efficiency. Even the government in developing regions such as Asia-Pacific and South America are formulating stringent regulations for environment protection. These stringent energy efficiency regulations are driving the use of WHRS in various manufacturing-oriented industries.
Currently, market players such as ABB Ltd. (Switzerland), Amec Foster Wheeler (U.K.), Ormat Technologies Inc. (U.S.), General Electric Co. (U.S.), Mitsubishi Heavy Industries Ltd. (Japan), Echogen Power Systems Inc. (U.S.), Econotherm Ltd. (U.K.), Thermax Limited (India), Siemens AG (Germany), and Cool Energy Inc. (Colorado) dominate the global WHR system market.
