Professional chemical engineer,specializing on clean energy and water technologies.He has more than 35 years of industrial experience in various process industries.Bulk of his experience were in R&D and commercialization.He has few innovative National and International patents on desalination and power generation. His latest patent is to store renewable energy such as solar, wind and geothermal in the form of SNG (synthetic natural gas) to generate base load power. You can eliminate the usage of fossil fuel and substitute with SNG with Zero Carbon emission. He is also a writer on Eastern philosophy, especially on Advaita Vedanta. He believes that science and Vedanta are two sides of the same coin. Science applies to this physical world, and it has its limitations. However, spirituality transcends science and the physical realm. It is your TRUE NATURE. Please check my LinkedIn profile.

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.

After a month’s pause, this series returns at a time when the intersection of energy security and water scarcity has never been more critical.


Green hydrogen is often presented as a solved pathway:
scale it, subsidize it, deploy it.


But engineering reality tells a different story.

Hydrogen is not just another fuel.
It is the smallest molecule in the universe, with properties that challenge materials, infrastructure, economics, and even system design itself.


Six Realities Often Overlooked

• The trillion-dollar subsidy gap required for global scale

• Materials challenges, including embrittlement in pipelines and storage systems

• Energy penalties across conversion, compression, and transport

• The water–energy nexus, often ignored in deployment strategies

• Infrastructure mismatch with existing hydrocarbon-based systems

• The atomic reality that makes hydrogen both powerful — and problematic


Beyond the Narrative

The goal is not to dismiss hydrogen. It is to place it within its true engineering and economic context.

Because the energy transition is not driven by headlines — it is governed by systems, constraints, and thermodynamics.

Are we designing energy systems around electrons alone — or are we overlooking the critical role of molecules?


CEWT Perspective

At Clean Energy and Water Technologies (CEWT), we believe the future is not about choosing between electrons and molecules.

It is about designing systems where both coexist — in balance, in continuity, and in alignment with physical reality.

1. Project Overview

Project: 135 MW Carbon Recycling Technology (CRT) Demonstration Plant
Proponent: Clean Energy and Water Technologies Pty Ltd (CEWT)
Location: Western Australia (Kwinana Industrial Region)

CRT establishes a closed carbon loop where captured CO₂ is continuously converted into renewable fuel (RNG) using hydrogen, enabling firm 24/7 power, the elimination of fossil dependency, and integration of renewable electricity with industrial systems.

2. Commercialisation Objective

Deliver Australia’s first grid-scale, firm, defossilised power system demonstrating continuous renewable-integrated power, industrial-scale carbon recycling, and a bankable architecture for replication.

3. Delivery Model

Blended finance, infrastructure-led model:
– Government Grants (~25%)
– Concessional Debt (~20–25%)
– Commercial Debt (~30–40%)
– Strategic Equity (selective, non-controlling)

4. Revenue & Bankability

Revenue Streams:
– Long-term PPA
– Industrial offtake
– Environmental certificates
– Grid services

Bankability:
– Anchor offtake
– Fixed EPC
– Vendor integration
– Policy alignment

5. Execution Pathway

Phase 1 (2026): FEED & Structuring
Phase 2 (2027): Financial Close
Phase 3 (2027–2029): Construction
Phase 4 (2030): Commissioning & COD

6. Strategic Partnerships

Collaboration with global partners for GTCC, SMR, methanation, and EPC delivery ensuring technical credibility and risk sharing.

7. National Impact
