More about FusionOne Technology:

FusionOne technology is an innovative approach to hydrogen production that involves the use of plastic waste as a feedstock. This process offers a promising solution to two major environmental challenges: plastic pollution and the transition to clean energy sources like hydrogen. Here’s a detailed explanation of the process along with specific data points:

1. Feedstock Collection and Preparation:
   • FusionOne technology begins with the collection of plastic waste, including various types such as polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyethylene terephthalate (PET).
   • The collected plastic waste undergoes sorting and cleaning processes to remove contaminants such as dirt, labels, and other non-plastic materials. This step ensures the purity of the feedstock for subsequent processing.
2. Plastic Pyrolysis:
   • Pyrolysis is the thermal decomposition of organic materials in the absence of oxygen. In the case of FusionOne technology, plastic waste is subjected to pyrolysis in specialized reactors at elevated temperatures (typically between 400°C to 800°C) and controlled conditions.
   • During pyrolysis, the plastic waste breaks down into its constituent hydrocarbons, primarily producing gases such as methane, ethylene, propylene, and other volatile organic compounds (VOCs). This process is crucial for converting the carbon-rich plastic waste into valuable hydrocarbon feedstocks.
3. Hydrogen Production via Steam Reforming:
   • The produced hydrocarbon gases from pyrolysis serve as feedstocks for steam reforming, a well-established industrial process for hydrogen production.
   • In steam reforming, the hydrocarbon gases react with steam (H2O) over a catalyst (typically nickel-based) at high temperatures (around 700°C to 1000°C) to produce hydrogen (H2) and carbon monoxide (CO) as primary products. The chemical reactions involved are:
     • CH₄+H₂O → CO + 3H₂
     • C_nH_m + _nH2O → _nCO + (2_n + m)H₂
   • The produced hydrogen gas is then separated from the reformate stream through processes such as pressure swing adsorption (PSA) or membrane separation.
4. Byproduct Utilization:
   • The carbon monoxide byproduct from steam reforming can be further reacted through the water-gas shift (WGS) reaction to produce additional hydrogen:
     • CO + H₂O → CO₂ + H₂
   • Additionally, any residual carbonaceous materials or char generated during pyrolysis can be utilized as a source of carbon for various applications, such as soil amendment or carbon black production.
5. Performance Metrics and Environmental Impact:
   • FusionOne technology offers several key performance metrics and environmental benefits:
     • Hydrogen Yield: The technology can achieve high hydrogen yields per unit of plastic waste input, typically ranging from 60% to 80%.
     • Energy Efficiency: Steam reforming is an energy-intensive process, but the utilization of plastic waste as a feedstock can improve the overall energy efficiency of hydrogen production compared to traditional methods.
     • Waste Reduction: By converting plastic waste into valuable hydrogen and carbon products, FusionOne technology helps mitigate the environmental impact of plastic pollution while contributing to the circular economy.
     • Emissions Reduction: Although the process generates carbon dioxide (CO2) emissions, the net environmental benefit depends on factors such as the source of energy used for process heat and the overall lifecycle emissions compared to conventional plastic disposal methods.
