According to Stratistics MRC, the Global Stirling Engine Market is accounted for $1.3 billion in 2025 and is expected to reach $2.4 billion by 2032 growing at a CAGR of 8.5% during the forecast period. A Stirling engine is a type of heat engine that operates by cyclic compression and expansion of air or another gas at different temperatures, converting heat energy into mechanical work. It works on the Stirling cycle, involving two main phases: heating the gas to expand it and cooling it to compress it, often using external heat sources like solar energy or combustion. Unlike internal combustion engines, Stirling engines are external combustion engines, meaning the combustion takes place outside the engine, offering high efficiency and low emissions.
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.
