H Power Biomass Power Plant in Honolulu, Hawaii | Waste-to-Energy Facility

H Power is a biomass power plant located in Honolulu, Hawaii, United States. With a capacity of 97.3 MW, it operates as a waste-to-energy facility, converting municipal solid waste into electricity. The plant is owned and operated by Covanta Honolulu Resource Recovery and is currently operational. The plant uses waste as its primary fuel, a common practice in biomass power generation. In the United States, such facilities are regulated under the Clean Air Act, including emissions standards for pollutants like SOx, NOx, and particulate matter. The technology typically involves combustion of waste in controlled conditions to generate steam for turbines. H Power plays a significant role in Honolulu's waste management and energy supply, reducing landfill dependence while providing renewable energy. Its location in an urban area underscores the importance of emission controls and community engagement. The plant contributes to Hawaii's renewable energy goals and grid resilience.

The plant's use of waste as fuel reduces methane emissions from landfills but requires stringent air pollution controls to manage SOx, NOx, and dioxins. Located in Honolulu, it serves a densely populated area, necessitating compliance with US EPA NAAQS and local regulations. The 97.3 MW capacity places it in the medium-to-large scale for biomass plants, with environmental impacts tied to fuel composition and combustion efficiency.
