SoftInWay and GTI Develop Design for Revolutionary New Engine

Burlington, MA, April 30th, 2019 – SoftInWay, Inc. and GTI announce the concept of a new kind of heat engine with the potential to achieve greater than 65% net electrical or mechanical power-conversion efficiency and provide ultra-low pollutant emissions at a competitive cost. In this DOE-funded project led by GTI, the partners are working together to further the sustainable use of fossil energy (FE) resources and reduce the risk and cost of advanced technologies.

SoftInWay, Inc. and GTI have collaborated to identify the best options for a sub-atmospheric modular hybrid heat engine (MHHE) for FE applications. SoftInWay’s engineers successfully performed thermodynamic cycle simulations, which helped determine the MHHE’s operating regimes. In addition, they designed the compressor and the turbine for low pressure and sub-atmospheric configurations and refined the integrated MHHE layout.

“At the end of the day, our overall goal is the advancement of science and technology. When SoftInWay was founded 20 years ago, our focus was turbomachinery component design. We have since expanded into system level design, creating and optimizing advanced thermodynamic cycles ranging from steam and gas to ORC and supercritical CO2 cycles in power plants. In this project with GTI, we are advancing power generation and improving upon the science and technology already in place. It is important to develop alternative energy options, but it is just as important to improve upon what already exists and continue to innovate, particularly when you are looking at a non-renewable resource like fossil energy. We have to make every bit of it count because so much of the world is depending on it,” said Dr. Leonid Moroz, SoftInWay’s CEO.

“State-of-the-art gas turbine power generators are less efficient relative to other generating technologies, so today’s energy market is looking for more efficient and cost-effective turbines or turbine-based modular hybrid solutions, and GTI’s research and engineering team is responding to market demand. The transformational MHHE concept we are developing represents a smart combination of a high-efficiency sub-atmospheric air turbine and multi-fuel reciprocating internal combustion engine with an advanced humidifying regenerator.

“This approach offers cleaner and more efficient capabilities than existing technologies. The modular heat engines provide flexibility in meeting power requirements because the small scale allows them to be combined to create larger sizes as needed,” said GTI’s project manager Dr. Yaroslav Chudnovsky.

Researchers and engineers from SoftInWay and GTI are focused on advancing the cutting edge in fossil energy-fueled power generation around the world. Thanks to the relatively low construction and operation costs, this project will marry the two ideas of advanced efficiency with competitive manufacturing cost, expanding the accessibility and affordability of power to more people worldwide.
