Green CHP has launched ETHOS (Energy, Thermal, and Heat Optimization Services), a comprehensive engineering service aimed at small to mid-sized energy users in industries where thermal loads and hot water operations are crucial. The service, designed for projects between 250 kW and 250 MW, provides technology-agnostic solutions tailored to commercial, industrial, and community-scale facilities that have historically been underserved. The approach focuses on data-driven design, integrating renewable CHP, thermal energy recovery, and system-level solutions to enhance performance. Green CHP's methodology considers real-world variables to deliver systems that balance efficiency, flexibility, and feasibility. ETHOS supports a range of project types and can be applied to both green and blue hydrogen projects, promoting high-efficiency system design from the beginning. The service is cost-effective, offering full system engineering, integration planning, and performance optimization. Green CHP's CEO highlighted the shift towards precision-engineered energy design, using data and tools to support smarter decisions and transition to better energy systems without compromising performance.
