questions about our proprietary technology:
Q. What is quick refueling?
A. The same way that hydrocarbon fuels are in use today, our Cryo technology matches this convenience. Filling equipment from empty to full in just a few minutes is an important necessity for commercial use cases.
Q. Your cycle cleans the local air?
A. Yes! As we capture atmospheric air this removes debris and other impurities, including CO2, leaving the local air much cleaner.
Q. What are the biggest advantages relative to lithium ion based battery systems?
A. First, storing energy as a Cryo based liquid provides the ability to store large quantities of energy at a very competitive cost. Second, for portable power use cases our process provides the ability to fuel in less than 5 minutes while also carrying up to 300 watt-hours per kilogram, important metrics that are superior to lithium ion systems currently on the market.
Q. Is condensing air into liquid new?
A. No, the process has been commercialized for over 100+ years. Liquid Air Energy Storage (LAES) is already being commercialized for various applications.
Q. Is the proprietary process from Cryo Energy Tech new?
A. Yes, we have improved all of the core steps resulting in a new version of an existing process.
Q. Is the expansion step proprietary?
A. Yes, when mechanical output or electricity is required, we reverse the process so the liquid changes state back into a gas. Yet another unique and novel feature is the way we avoid frost issues while also incorporating the ability to use waste heat during the expansion step.
Q. Are you compressing air?
A. Yes, we increase the pressure of the air before condensing into liquid state.
Q. Isn’t compressing air extremely inefficient?
A. Some designs are inefficient but our proprietary design includes a unique and novel method of increasing the pressure of a gas, such as air, without the inefficiencies.
Q. Are you compressing air isothermally?
A. Not exactly, we increase the pressure of a gas and liquid simultaneously to help minimize the increase of temperature of the gas.
Q. Why is this more efficient?
A. After compression, we separate the gas from the liquid while also recuperating some of the potential energy which can be fed into other cycle steps or transferred elsewhere, increasing the overall efficiency of the compression step.
Q. Do you capture waste heat from the compression step?
A. No, we minimize the amount of waste heat created during the compression step.
Q. Is waste heat important to the cycle?
A. Yes, our process is so efficient at converting waste heat that it is possible for the system to have a COP greater than 1, which means our method of energy storage is NOT a net consumer of electricity. Every other energy storage system consumes electricity.
Q. You add waste heat during the condensing step?
A. Yes! Another novel feature of our proprietary design is the ability to supplement the output with waste heat, allowing more “cold” to be available for condensing. More cold results in more gas being condensed into liquid form.
Q. What about storage vessels?
A. There are established suppliers that provide storage vessels for cryogenic based liquids. Our designs utilize lower cost materials relative to previous cryogenic based systems.
Q. How long can Cryo based liquids remain in storage?
A. The average loss is less than 1% per day, but we can increase the overall length of time to multiple weeks with minimum losses when including waste heat from the other steps.
Q. How do you supplement the LNG process?
A. Our cycle allows the use of "on-demand" LNG loading/unloading along with converting waste heat and off peak electricity into Cryo to avoid peak and demand charges.
Q. How do you supplement the industrial gas process?
A. Just like the LNG process, we can avoid peak and demand charges. Also, we can deliver feedstock for the distillation process that produces Nitrogen, Oxygen, Argon, etc.
