CTI Hydrogen (H₂)
CLEAN, ECONOMIC HYDROGEN
Acceleware believes that integrating CTI-driven RF as the energy input for a pyrolysis reactor could result in the cleanest, most flexible, and most economic hydrogen globally. Hydrogen from pyrolysis is often referred to as turquoise, because it combines the cost efficiency of blue hydrogen with the emissions reduction benefits of green hydrogen. Another major environmental benefit is that the pyrolysis process requires zero fresh water, and does not require disposal of any resulting wastewater.
Pyrolysis is quickly gaining attention due to environmental benefits and economic potential. Having greater than 98 percent conversion efficiency means that CTI-driven RF energy could be the most economic and effective way to commercialize and scale-up hydrogen production. CTI pyrolysis is expected to be flexible, scalable, and capable of distributed low-cost production with no carbon emissions.
how it works
Acceleware has a working commercial scale version of the CTI platform which operates at 20 kHz to 120 kHz and at a power range from 100 kW to over 10 MW. The power of this heating ‘engine’ could allow for significant improvements to a pyrolysis reaction since CTI produced RF energy could provide conversion efficiency and cost advantages over other energy sources. The CTI technology has (1) been developed over seven years and is currently operating at a 2 MW maximum power level, (2) is proven and capable of scaling to over 10 MW, (3) provides a rapid path to scale hydrogen production to industrial levels of 20 tons /day at 10 MW while maintaining unparalleled energy conversion efficiency.
Acceleware is currently engaging with partners to accelerate CTI hydrogen technology development.
CTI BULK SOLIDS / CROP DRYING
TIME FOR INNOVATION IMPROVEMENTS
The bulk solids drying market includes the drying of crops, lumber, pulp, pet foods, chemicals, medicines, and minerals. This sector contributes to approximately six percent of global emissions, primarily because most drying processes heat air by burning methane or propane (drying through evaporation), and have seen limited innovation over the past two decades. This process is inefficient and makes uniform drying difficult: hot air is blown over the product to evaporate water from its surface, which is both emissions intensive and costly.
Researchers have been exploring the use of electromagnetic (EM) energy (microwaves and RF are different frequency ranges of EM energy) to improve the efficiency, emissions, and cost of the drying process. Widespread adoption, however, has not been achievable to date due to cost and scalability limitations.
We firmly believe CTI can change this, as it allows for volumetric heating via RF energy. Volumetric heating could reach water molecules inside the product, allowing for faster and more uniform drying with much less energy and much lower emissions.
THE RF DRYING ADVANTAGE
The CTI is a proven high-power high efficiency platform that is low cost, and can be applied to bulk solids drying.
RF drying advantages:
- Efficient energy transfer – minimal heat losses, maximum energy delivered directly to the water.
- Volumetric heating – results in fast and uniform water removal. This can drive energy input reductions of up to 50 percent for the drying process by delivering energy directly to the water molecule.
- Lower energy cost plus faster drying time can drive operating cost reductions of 50 percent.
- Precise temperature regulation – allowing for higher quality product which can often command a premium price (i.e. grain and food product markets).
- Tight process control and drying customization to optimize consistent results.
CTI INDUSTRIAL HEATING
CTI FOR EFFICIENT HEATING
The commercial and industrial process heating markets combined represent a $28B market that contributed to a massive twelve percent of global GHG emissions in 2020.
Commercial heating refers to the heating of commercial buildings like shopping malls, offices, universities, and hospitals. Industrial process heating is the use of thermal energy used directly in the preparation or treatment of materials used to produce manufactured goods, and could include chemical, pharmaceutical, steel, and mining, among others.
CTI can reduce emissions in the commercial heating sector by replacing gas and coal fired boilers with clean RF heating technology.
Likewise, CTI could modernize industrial heating processes, which have not experienced a significant technology update in nearly one hundred years – since the introduction of the pressure vessel.
California, New York, and the U.K. all have legislation around, or outright bans on, the sales of fossil-fuel boiler systems. A growing number of major cities have voted to ban natural gas use by 2050 – the drive for a cleaner, more efficient technology is strong and clear.
RF ADVANTAGES FOR INDUSTRIAL PROCESS HEATING
Volumetric heating means RF can deliver energy to a large volume of water, as opposed to only the surface area of water near an electric heating element or a pipe that has been heated by gas combustion.
RF energy provides significant improvements to heating efficiency versus a typical heating element that relies on conduction, as it can deliver energy directly to each water molecule.
Efficiency improvements, combined with volumetric heating capabilities, could allow a CTI system to heat a large volume of water quickly enough to provide on-demand steam or hot water, even in cases where traditional boilers must maintain a high temperature in a large volume of water 24x7x365.
