1. The Context

Billions have already been invested in hydrogen. Only now are we asking whether the fundamentals actually work.
The challenge is not just economic or technological. It is rooted in thermodynamics.

2. The Scientific Foundation

Hydrogen is not a primary energy source. It is a high-Gibbs-free-energy molecule.
This means energy must be supplied to produce it (via electrolysis), and losses are inevitable when converting it back into usable energy.
These losses are not due to immature technology—fundamental thermodynamic limits govern them.

3. The Core Mistake

The industry has made a category error by treating hydrogen as:
• A fuel
• A traded commodity
• An export vector

However, physics supports hydrogen primarily as:
• A reactive intermediate
• A system-integrated molecule

When used outside this role, inefficiencies become unavoidable.

4. Why Carriers Do Not Solve the Problem

Hydrogen carriers such as ammonia, LOHCs, and e-fuels introduce additional conversion steps.
Each step adds entropy, energy loss, and capital cost.

This does not solve hydrogen’s limitations—it compounds them.

5. The System Perspective

The challenge is not hydrogen itself, but where it is placed within the energy system.
When used as a traded fuel, it struggles.
When used within a closed, integrated system, its performance improves significantly.

6. Conclusion

Hydrogen is not a dead end. But it is misapplied in current energy strategies.

The real breakthrough will not come from better hydrogen technologies alone.
It will come from better system design—placing hydrogen where thermodynamics actually supports it.

We do not have a hydrogen problem.
We have a system design problem misunderstood as a fuel problem.
