“Combined Heat will grow to USD 35.2 billion by 2026 (forecast year) from USD 26.6 billion in 2021 (estimated year), at a CAGR of 5.8% during the forecast period.
Combined heat and power (CHP) is an energy-efficient technology that generates electricity and captures the heat that would otherwise be wasted to provide useful thermal energy, such as steam or hot water. This steam or hot water, in turn, can be used for heating, cooling, and other domestic and industrial processes. The conventional method of producing usable heat and power separately has a typical combined efficiency of 45%, where CHP systems can operate at levels as high as 80%. CHP can be implemented for different types of prime movers, such as gas turbines, steam turbines, reciprocating engines, fuel cells, and microturbines. CHP is also called cogeneration, and it can be used in an individual facility/building or a district energy/utility resource. The technology is typically employed at facilities where there is a need for electricity and thermal energy. It provides benefits such as a reduction in dependency on grid support due to on-site electricity generation, enhanced reliability, reduced costs of energy and initial setup, increased resiliency against power disruption, and reduction in harmful emissions. Critical electrical and thermal loads can be handled by CHP systems during grid power outages. Micro turbines are a type of combustion turbine that produces both heat and electricity on a relatively small scale.
The 10–150 MW segment is expected to dominate the combined heat and power market, by capacity, during the forecast period.
The 10–150 MW segment accounted for the largest share of 37.5% of the CHP market in 2020. This segment consists of larger CHP plants mainly with reciprocating engines such as gas and diesel engines as prime movers, particularly used by industrial, commercial, and utilities end users. The demand for diesel power engines in this segment comes from utility-scale diesel power plants, large industrial plants, captive generation, and independent power producers (IPPs).
Some of the prominent key players are GE (US),Siemens (Germany),2G Energy (Germany),Wärtsilä (Finland),Mitsubishi Hitachi Power System (Japan),FuelCell Energy (US),Clarke Energy (UK)
The gas turbine segment is expected to dominate the combined heat and power market, as prime mover, during the forecast period.
The gas turbine segment accounted for the largest share of 32.9% in 2020. A gas turbine is a type of internal combustion (IC) engine where inlet air is compressed and sprayed with fuel. The mixture is thereafter ignited in a combustion chamber and allowed to flow at high temperature and pressure through the turbine. The gaseous mixture passes through the turbine nozzles, which further channelize the kinetic energy of the hot air flow onto the blades. The turbine blades, which are mounted on a rotor, rotate with the impact of the high-velocity air. The rotary motion is used to turn a shaft, which performs tasks such as driving an electric generator. Gas turbines are used for power generation and in the mechanical drives used by oil & gas and other industries.
The natural gas segment is expected to dominate the combined heat and power market, by communication technology, during the forecast period.
The natural gas segment accounted for the largest market share of 53.4% in 2020. Natural gas is mostly used in gas engines for electricity generation, as it burns cleaner and has low carbon emissions compared with other types of fuels. It also emits low levels of nitrogen oxide, sulfur dioxide, and particulate matter. The consumption of natural gas has led to rising concerns over global warming.
Asia Pacific is expected to lead the CHP market
Asia Pacific accounted for a 55.7% share of the CHP market in 2020. The countries covered in the region are China, Japan, South Korea, India, Australia, and the Rest of Asia Pacific. The market is expected to grow due to rapid industrialization, urbanization, and economic growth in the region, leading to the installation of new CHP systems in various emerging economies.
The CHP market is expected to grow in countries such as China and India due to infrastructural expansions, ongoing power generation projects, and technological innovations. Investments in large new gas-fired cogeneration plants and large coal-fired plants, along with rising demand for electricity, are expected to drive the growth of the Asia Pacific combined heat and power market over the next five years.
