"Transforming the Energy Landscape with HTI’s Hydrogen Fuel Conversion Breakthrough"
System Concept and Novelty:
The concept of producing hydrogen via electrolysis, as practical way to capture and store large quantities of renewable energy has been hypothesized and studied for many years. Today, there is unprecedented interest in using electrolysis technology to provide grid scale energy storage and ancillary services in markets where there is a high penetration of renewable energy. However, if the produced hydrogen is limited to a simple “power-to-power” (P2P) kind of play, it is often difficult to justify the investment. Consequently, there is applied research going on to validate alternate high value uses for the hydrogen, including power-to-gas (P2G) and power-to-fuel (e.g. for transportation, P2F). However, there is only one energy conversion technology that enables the use of renewable hydrogen to bridge all of the commercial energy silos, including zero-emission steam production. Hydrogen Technologies, Inc. has developed a breakthrough technology that enables the transformation of hydrogen and oxygen gas to high value steam via their Dynamic Combustion ChamberTM (DCC). This device provides the mechanism for converting renewable hydrogen/oxygen to useful steam in a high efficiency and pollution free process.

Once produced, the steam from the DCC boiler can be used to serve a variety of high value energy demands at the building or campus level. For example, steam driven chillers for cooling and refrigeration can address high summer loads for these functions, and provide significant cost reductions (estimated at 20% on a life cycle basis) during times of peak demand, particularly when the electrolyzer is operating on low cost power from stranded renewables. In addition, the steam can be converted back to electricity via a new generation of microturbines, specifically designed to capture waste steam. Ultimately, these microturbines operating in a CHP configuration can achieve a 70% efficiency in converting steam energy to heat and electricity.
The DCC boiler technology is a real-world disruptive technology that is providing a flexible system for converting hydrogen energy storage into useful steam and heat. While other projects are already addressing P2G, P2P, and P2F applications for renewable hydrogen, no other efforts of a meaningful scale are demonstrating the “power-to-steam” (P2S) concept. The value proposition for this technology is particularly strong at the building scale, because in building systems the vast majority of energy demand is in the form of addressing thermal loads. Thus, the technology offers an opportunity to address real world building system needs.
