15 Ways to Power the Future: Exploring Clean Hydrogen Production Methods

The Quest for Clean Hydrogen

Hydrogen has the potential to be a game-changer in the fight against climate change. As a clean-burning fuel, it produces only water vapor when used, making it a desirable alternative to fossil fuels. However, the production of hydrogen itself isn't always clean. Traditional methods often rely on fossil fuels, creating emissions that counteract the benefits of using hydrogen as a fuel source.

This blog post dives into the exciting world of clean hydrogen production methods. We'll explore 15 different techniques, each with its own advantages and areas for development. From harnessing the power of sunlight to utilizing organic materials, scientists are constantly innovating ways to produce hydrogen without leaving a negative impact on the environment.

Below, I have described 15 different methods for producing clean hydrogen.

🟩 1) Alkaline Hydrogen Electrolyser;

Cathode: 2H2O + (2e−) → H2 + 2OH−
Anode: 2(OH−) → H2O + ½ O2 + 2e−

H2O → H2 + (½ O2)

🟩 2) Anion Exchange Membranes (AEM) Hydrogen Electrolysers;

Cathode: 4H2O + (4e−) → 4OH− + 2H2
Anode: 4OH−→ 2H2O + O2 + (4e−)

4H2O → 2H2O + O2 + 2(H2)

🟩 3) Molten Carbonate Electrolysis Cell (MCEC);

H2O + CO2 + 2e−→ H2+(CO-2)3
(CO−2)3 → CO2 + 0.5 O2 + 2e−

H2O + CO2,fe → H2 + 0.5 O2 + CO2,oe

🟩 4) Proton Exchange Membrane (PEM);

Cathode: (2H+) + (2e−)→H2
Anode: H2O → (2H+) + ½ O2 + 2e−

2H2O → H2 + ½ O2

🟩 5) Acidic/Alkaline Amphoteric;

Cathode: (2H+) + (2e−)→ H2
Anode: (4OH−) → 2H2O + O2 + 4e−

(4OH−) + (4H+) → 2H2O + O2 + 2H2

🟩 6) Solid Oxide Electrolysers Cell (SOEC);

Cathode: H2O + (2e−)→H2 + (O2-)
Anode: O2−→ ½ O2 + (2e−)

H2O → H2 + ½ O2

🟩 7) Microbial Electrolysis Cells (MECs);

Cathode: (8H+) + 8e−→ 4H2
Anode: (CH3COO−) + 4H2O → 2HCO3− + (9H+) + 8e−

(CH3COO−) + 4H2O → (2HCO3−) + (H+) + 4H2

🟩 8) Photoelectrochemical (PEC);

Cathode: (4H+) + 4e−→2H2
Anode: 2H2O → (4H+) + O2 + 4e−

2H2O + (4H+) → (4H+) + O2 + 2H2

🟩 9) E-TAC Hydrogen Electrolyser;

Electrochemical, Thermally Activated Chemical (E-TAC) generates hydrogen and oxygen individually in two steps (no risk of H₂ /O₂ mixing), the Electrochemical and Thermally-Activated Chemical stages.

🟩 10) Capillary-Fed Electrolysis cell (CFE);

2(H2O) (l) ⇌ 2H2 (g) + O2 (g) E0 = -1.229V

🟩 11) SunHydrogen Photoelectrosynthetically Active Heterostructures (PAH);

Each PAH nanoparticle is a microscopic device composed of countless layers, allowing the solar electrolysis reaction.

🟩 12) Photoelectrolysis Hydrogen Panel;

2(H2O) + light + Solhyd "Hydrogen Panel" → 2(H2) + O2

3 different methods of photoelectrolysis:

1- photoelectrolysis using a hydrogen panel;

2- photoelectrolysis using a photoelectrode with a photoabsorber;

3- photoelectrolysis with a photoelectrocatalyst.

🟩 13) Methane pyrolysis from biogas or landfill gas powered by renewable electricity;

CH4 → 2H2 + C

A. Enthalpy change of this reaction (37.4 kJ/mol H2) is less than water electrolysis (285.8 kJ/mol H2).

B. Pyrolysis produces no CO2, unlike Steam methane reforming (SMR).

C. Turquoise hydrogen costs less than green hydrogen and can have a similar cost as blue hydrogen (SMR + CCS).

🟩 14) H2EG’s High-Yield Fast Pyrolysis;

Biomass → 40% H2 + 40% CO + 10% CH4 + 10% CO2

🟩 15) Direct air electrolysis (DAE).

Direct hydrogen production from the air via in-situ moisture capture by hygroscopic electrolyte and electrolysis powered by solar or wind with a current density up to 574 mA cm−2.

Cathode reaction:
(4H+) + 4e- → 2H2

Anode reaction:
2H2O → O2 + (4H+) + 4e-
