Capacity Insight

The 1 MW – 5 MW capacity segment is dominant, capturing over 41.2% market share in 2024. This range is favoured for its versatility, striking an optimal balance between cost-effectiveness and performance for various small to medium-scale applications. It's ideal for distributed power generation, including industrial waste heat recovery from sources like engine exhaust or furnace flue gases, combined heat and power (CHP) systems, and smaller-scale renewable energy projects such as biomass combustion or moderate-temperature geothermal sites. Its suitability for diverse industrial and commercial settings with varying space and budget constraints further solidifies its market leadership.

End-Use Insight

Gas turbines lead the end-use segment, accounting for more than 65% market share in 2024. The integration of ORC systems with industrial gas turbines is a highly effective method for enhancing overall energy efficiency by converting substantial amounts of exhaust waste heat, which would otherwise be lost, into valuable additional electricity. This waste heat recovery is particularly critical in industries facing stringent environmental regulations and mounting pressure to reduce carbon emissions and improve energy sustainability. The synergy between gas turbines and ORCs offers a compelling solution for optimising power generation in industrial processes and power plants.
