Interactive Levelized Cost of Thermal Energy (LCOT) Calculator

09 Jun 2025

The Levelized Cost of Thermal Energy (LCOT) Calculator is an interactive tool developed to support techno-economic analysis of various heating technologies. This tool allows users to input system and economic parameters and interactively evaluates the LCOT for different heating systems including natural gas boilers (NGB), heat pumps (HP), and hydrogen boilers (HB).

The calculator is designed to help policymakers, researchers, and engineers better understand how changes in capital cost, efficiency, fuel price, lifetime, or discount rate affect the competitiveness of thermal energy systems over their lifetime.
