Sustainable innovations Inc. and its partners, Greenway Energy and Savannah River National Laboratory, are collaborating to maximise the benefits of two cutting edge hydrogen (H2) compressor technologies by combining them into one high reliability, high efficiency hybrid compressor.

This important research and development (R&D) effort will address one of the most common problems in the H2 fuelling industry- how to cost effectively compress H2 for storage on board a vehicle.

Conventional compressor technology has proven less than optimal for H2 fuelling in early fuel cell vehicle markets like California. According to the department of Energy (DOE), the poor reliability of mechanical compressors is related to operating conditions at the H2 stations for which mechanical compressors were not designed.

Dr. Trent Molter, President and CEO of Sustainable Innovations says, “The goal of the hybrid compressor project is, for the first time, to demonstrate that H2 can be efficiently compressed directly to vehicle fueling pressure at significant scale while avoiding the unacceptable downtime and maintenance pitfalls that have hampered mechanical compressors. Simply put, we’re demonstrating a better way.”

Sustainable Innovations’ high efficiency, electrochemical H2 compressor will be integrated with Greenway Energy’s metal hydride compressor, which leverages advanced technology previously developed at the US DOE’s Savannah River National Laboratory.

President of Greenway Energy, Dr. Scott Greenway, “We believe that this breakthrough integrated system approach leverages the unique high-reliability attributes of each technology to create a long-awaited solution for the H2 fueling industry.”

“Our H2 compression solution is scalable to meet the current and projected needs for commercial fueling stations, will save consumers money, and serves as a keystone in addressing climate change,” added Dr. Molter.

Sustainable Innovations’ project is funded through a sub-award from the US DOE Office of Energy Efficiency and Renewable Energy (EERE), arising from the Company’s rich H2 technology heritage.

This project complements Sustainable Innovations’ concurrent efforts to develop a H2 impurity sensor for vehicular fueling, and its H2RENEW™ H2 recycling system for metals, glass and semiconductor processing.
