Tecogen Inc.(OTCQX: TGEN), a clean energy company providing ultra-efficient and clean on-site power, heating, and cooling equipment, is pleased to announce the launch of its smart Tecochill Hybrid-Drive Air-Cooled chiller (the “Hybrid-Drive”) at AHR 2023, the largest HVAC tradeshow in North America. The Hybrid-Drive chiller seamlessly combines two power sources, economical natural gas and electric power from the grid, offering customers up to 50% lower operating costs compared to alternative chillers, as well as dual-power-source resiliency. When the Hybrid-Drive is powered by the chiller’s integral natural gas engine, it produces chilled water for air-conditioning plus free engine heat that is recovered to produce usable hot water. Competing solutions are less efficient, have a higher greenhouse gas footprint, have a higher energy operating cost, and require a separate boiler to produce hot water.
The Hybrid-Drive can track inputs from the electric power grid to enable customers to optimize economic savings and/or greenhouse gas reductions. Marginal grid power generation in the United States is currently predominantly fossil fuel-based, particularly during peak demand periods, so customers able to utilize both the chilled water and hot water generated by the chiller will benefit from both the lowest operating cost and the lowest greenhouse gas footprint. The Hybrid-Drive can maximize greenhouse gas reductions by using power from the electric grid when the grid incrementally is powered by renewable energy and can switch to engine power when the grid is generating higher greenhouse gas emissions. In addition, when grid power is more expensive during periods of high demand, the Hybrid-Drive can switch to operating on engine power, and then switch back to operating on the grid if prices become lower, enabling customers to optimize operations as electric grid costs and greenhouse gas emissions fluctuate.
