374Water Inc. announced that its AirSCWO units will include its newly launched HEC-Prime engine that converts waste steam and gasses into renewable energy. Offering proprietary technology and design, the HEC-Prime was developed in partnership with Swedish-based energy company Maston Group, exclusively for 374Water. The solution consists of five pistons and turbines that collect the high-pressure mix gas (steam) to rotate and spin a shaft connected to a generator unit.

electricity is one of three byproducts of the AirSCWO process, along with clean water and minerals, designating the HEC-Prime as an integral part of a larger system that produces these derivatives. The first of its kind, the technology provides a sustainable solution to energy and resource scarcity, furthering 374Water's objective to promote a circular economy.
