Step-by-Step Instructions
1. Assemble the 100W solar panel and connect it to a 12V deep cycle battery to store energy.
2. Use a DC-DC boost converter to raise the 12V battery output to around 400V DC needed for the plasma reactor.
3. Build or program an H-bridge MOSFET driver circuit controlled by a microcontroller (Arduino) to generate the high-frequency AC voltage (~kHz range) for the dielectric barrier discharge.
4. Construct the plasma reactor by inserting stainless steel mesh electrodes inside a quartz or glass tube separated by a dielectric barrier (e.g., mica sheet).
5. Connect the boosted high-voltage AC output to the plasma reactor electrodes.
6. Set up a controlled methane gas feed from a biogas fermentation bottle or a small methane cylinder through gas tubing into the reactor.
7. Power the system using solar energy stored in the battery, ensuring the inverter provides stable 120V/230V AC with minimal total harmonic distortion for consistent plasma generation.
8. Monitor the plasma discharge visually and with sensors if available; adjust frequency and voltage for optimal methane conversion.
9. Collect hydrogen gas output downstream with proper tubing and capture or safely handle solid carbon deposits formed inside the reactor.
10. Enclose all electronics safely in a box, ensuring ventilation and accessibility for maintenance.
11. Test the system off-grid and verify increased hydrogen yield and methane conversion efficiency compared to grid-supplied power.
