Stirling Engines Market Trends




  • Growing demand for a low-emissions alternative to IC engines will driving the market growth




Market CAGR for stirling engine is being driven by the increasing demand for a low-emissions alternative to engines. The fact that Stirling engines have a low-temperature difference that no other heat engine has is one of the primary factors contributing to the market value increase for these engines. Traditional internal combustion engines cause air pollution and glasshouse gas emissions that impair the environment and human health. Internal combustion (IC) engine alternatives are now in the research, development, and demonstration stages. The Stirling engine is a very clean alternative to IC engines. Stirling engines, despite being invented over 200 years ago, were not commercially viable due to technological restrictions. Concentrated solar electricity is more effective when powered by a Stirling engine powered by the sun's temperature gradient, which may operate with a minor temperature gradient.


Additionally, according to the Statistical Review of Energy 2022, solar energy capacity expanded by 226 GW in 2021, nearly matching the record increase of 236 GW in 2020. Solar energy generation has also grown from 846.2 TWH in 2020 to 1033 TWH in 2021. This demonstrates that the demand for low-emission options and the usage of renewable energy sources for the sterling engine will move the sterling engine market forwards.


Moreover, the rise in oil costs is likely to assist the Stirling engine business. Crude prices have also risen dramatically, from 41.3$/bbl. in 2020 to 97.1$/bbl. in 2022, due to peak oil and climate change, or a spike in the price of conventional fuels, according to the World Bank Commodities Price Data 2023. During the review period, these factors are expected to drive increase the market for Stirling engines. According to the IEA, the average price of oil in 2021 will be $70.91 per barrel, the second-highest level since 2015. energy prices will skyrocket in 2021.


For instance, oil prices soared by more than 70% between 2021 and 2020, with Brent or West Texas Intermediate completing the year at almost $70 per barrel. The price increase will cause a move away from fossil fuels and towards renewable energy sources for engines, accelerating the market growth of sterling engines. Hence, resulting in driving the Stirling Engines market revenue.


Stirling Engines Market Segment Insights:


Stirling Engines Type Insights


The stirling engines market segmentation, based on type includes alpha, beta, gamma, and others. In 2022, the alpha category dominated the market. The fundamental goal of this technique is to minimise the size and weight of traditional IC engines, allowing them to be put in previously inconceivable devices/equipment due to their huge and heavy dimensions. Furthermore, Alpha Stirling engines are a type of internal combustion engine that converts energy from any source (including gasoline, diesel, and solar power) into usable working energy. The main purpose of this technology is to reduce the size and weight of conventional IC engines, allowing them to be used in a variety of devices and equipment that were previously impracticable due to their massive and heavy proportions.


Stirling Engines Application Insights


The stirling engines market segmentation, based on application, includes heating and cooling, solar power generation, marine engines, and others. The heating and cooling category generated the most income in 2022.  The increasing use of cryogenic refrigeration systems in various regions and in various industries has driven the demand for stirling engines market.


Stirling Engines End Use Insights


The stirling engines market segmentation, based on end use, includes residential, commercial, and utility. The utility category generated the most income in 2022. Increasing demand for energy-efficient and eco-friendly products is anticipated to be the primary force propelling product demand in this application segment. Residential application is also anticipated to experience significant growth during the forecast period due to consumers' growing awareness of energy conservation. Due to the rising adoption of furnaces and other heating devices in commercial establishments such as hotels, restaurants, and hospitals, among others, commercial applications are expected to grow steadily over the forecast period.
