Problem Statement:
Current hydrogen production techniques, such as steam reforming and electrolysis, are burdened by high energy requirements and negative effects on the environmental. These methods are costly and contribute to carbon emissions, making them unsustainable in the long term. Our project seek to address these issues by exploring nature-inspired solutions. In particular, we plan to test a bio-chemical process within a thermo-chemical system, which promises to be faster and more efficient than traditional methane combustion. We think this strategy can be scaled up for sustainable hydrogen production because it has demonstrated impressive efficiency in natural processes.
Proposed Solution Overview:
Our suggested reactions, which take their cue from the efficiency of nature, show promising thermodynamic properties for the production of hydrogen in a thermo-chemical system. We are concentrating on the following reactions:
Reaction 1 : 6CH4+2H2O+10O2 --> 6CO2+4H2+10H2O
Reaction 2: C6H12O6+H2O+5O2 --> 6CO2+2H2+5H2O
These innovative approaches not only offer clean and renewable energy sources but also minimize energy inputs, thus advancing the feasibility and scalability of hydrogen production. Our simulations have affirmed the viability of these approaches, showcasing stable and efficient hydrogen production. Based on standard conditions, they demonstrate favorable thermodynamic properties, as shown by the calculated standard enthalpy (Delta H°) and standard Gibbs free energy (Delta G°).
Thermodynamic Analysis:
Standard Enthalpy (Delta H°): Reaction 1's negative value of -3846 kJ/mol shows that the reaction is exothermic, which means that heat is released into the environment.
Standard Gibbs Free Energy (Delta G°): For Reaction 1, the value is about -3890 kJ/mol. This indicates that, under standard conditions, the reaction is spontaneous, meaning it will proceed forward in the absence of external energy input.
Simulation Results:
Our models validate the feasibility of our methods, demonstrating steady and effective hydrogen production that is similar to natural processes. This graph shows the steady production of hydrogen by showing the concentrations of gases over time.

Conclusion:
Testing this bio-chemical process within a thermo-chemical system holds immense potential for transform the hydrogen economy. By mimicking nature’s efficiency, we can achieve faster and more efficient hydrogen production compared to current methane combustion/reforming methods, thereby reducing energy demands and environmental impacts.
When we were working on dark fermentation, we discovered that certain living things could completely oxidize glucose or methane to carbon dioxide if they had access to water and oxygen in the right ratios. Opportunities to forecast and validate additional reactions will arise from this validation.
Feedback Requested:
We encourage collaborators to discuss and offer their perspectives on our suggested reactions, which are workable at standard pressure and temperature levels. We value your opinions as we investigate sustainable hydrogen production. I appreciate you taking the time to respond.
When I mentioned 'we,' I was referring to our team working on exploring innovative bio-chemical processes for hydrogen production.
Hi, We appreciate your interest. We are investigating biological processes that resemble dark and photo fermentation, in which some microbes have demonstrated the capacity to undergo biochemical reactions and produce hydrogen gas.
Although the creation of oxygen by photosynthesis is well known, our focus is on less well-known mechanisms that might be able to explain the underground deposits of hydrogen and natural gas found during the search for fossil fuels.
