UK firm turns plastic waste into hydrogen, targets 35 tons daily for clean energy
Industry newsThe FTU processes 2.5 tons of waste plastic per day. While this is smaller than the anticipated 35 tons per day capacity of a future commercial unit, the FTU replicates the core processes and parameters in a controlled environment.
FTU provides a platform for evaluating the viability of processing various waste plastic feedstocks.
It operates using a pyrolysis process within a rotary kiln, which breaks down the plastic materials into their constituent chemical components. Pyrolysis is a thermochemical decomposition process that occurs in the absence of oxygen.
The primary product generated by this thermochemical process is syngas. Syngas is a mixture of gases, predominantly hydrogen, methane, and carbon monoxide.
The Powerhouse system is specifically engineered to maximize the proportion of hydrogen within the syngas mixture, as hydrogen is the most desirable and valuable output.
Before this syngas can be utilized, it undergoes a crucial cleaning and cooling stage. This purification process removes any unwanted acidic compounds or other impurities, resulting in a clean syngas stream ready for various applications.
This cleaned syngas can then be directly used for energy production (e.g., in a gas turbine), or it can be further processed to create other valuable products, including pure hydrogen fuel.
The system, however, incorporates the capability for process modification. It will allow for the introduction of steam or oxygen, which enables gasification processes.
The unit facilitates the ability to test different waste plastic types, and to adjust process parameters, in order to optimize the hydrogen production.
This flexibility allows Powerhouse to explore the potential of its DMG technology across different waste streams and assess its suitability for handling various types of plastic waste.
