Article 1: Defossilisation – A New Framework for the Global Energy Transition
The global energy transition has largely been framed around one objective: decarbonisation.
But carbon itself is not the fundamental problem.
Carbon is an essential element of life, industry and many of the fuels and materials on which modern society depends.
The deeper problem is the continuous movement of geological carbon into the active carbon cycle.
Coal, oil and natural gas contain carbon that has remained underground for millions of years. When these resources are extracted and consumed, additional carbon is introduced into the atmosphere-ocean-biosphere system.
That suggests a different way of defining the long-term objective:
Defossilisation
Defossilisation means progressively reducing—and ultimately eliminating wherever technically and economically possible—the requirement for newly extracted fossil carbon.
Follow the carbon
Consider the conventional fossil-energy pathway:
Geological carbon → extraction → processing → fuel → useful energy → atmospheric CO₂
Most climate policy focuses strongly on the final part of that chain: emissions.
Defossilisation asks us to look at the beginning as well.
How much new geological carbon must continuously enter the economic system?
That question produces a useful physical metric:
Fossil carbon entering the system / useful energy or product delivered
The objective is to drive that ratio progressively toward zero.
This is not an argument against decarbonisation
Electrification, renewable electricity, efficiency, batteries, hydrogen, carbon capture and genuine carbon removal can all contribute.
The distinction is one of system boundaries.
A technology may reduce emissions at one point while still depending elsewhere on fossil extraction, fossil-derived hydrogen, fossil backup power or carbon-intensive supply chains.
Defossilisation therefore asks us to examine the whole material and energy pathway.
Renewable electricity changes the equation
As solar and wind become increasingly competitive, renewable electricity can become more than simply a replacement source of electrons.
It can become the primary energy input for entirely new industrial systems.
Renewable electricity can directly power equipment.
It can produce hydrogen.
Hydrogen can provide industrial heat, act as a reducing agent, or react with recovered CO₂ to produce carbon-containing molecules.
This introduces another possibility.
Instead of continually extracting carbon:
Extract → use → emit
Some applications could increasingly operate through:
Recover → reuse → recover
with renewable energy continually entering the cycle.
Carbon does not necessarily have to disappear
This distinction is important.
A future energy system may still contain methane, carbon monoxide, carbon dioxide and carbon-based industrial products.
The critical question is where their carbon originated and where it ultimately goes.
A carbon atom recovered from an industrial process and reused is physically different, from a system-accounting perspective, from introducing another carbon atom from a geological reservoir.
This leads from a linear fossil-carbon economy toward a managed circular-carbon economy.
Measure before making the environmental claim
Defossilisation must also be measurable.
For any proposed system we should be able to establish:
Fossil carbon entering + recycled carbon circulating + carbon leaving the system
alongside the complete energy and water balances.
Only after establishing those physical flows should environmental claims be made.
That approach becomes increasingly important as regulators, customers, investors and communities demand evidence rather than broad labels such as green, clean or carbon neutral.
A technology-neutral framework
Perhaps the greatest advantage of defossilisation is that it does not prescribe one technology.
If direct electrification provides the lowest-cost reliable pathway with the lowest fossil-carbon requirement, use it.
If batteries provide the required storage, use them.
Where hydrogen is the appropriate molecule, use hydrogen.
Where permanent carbon removal is required, capture and store carbon permanently.
And where recovered carbon can provide useful system value without requiring continued fossil extraction, investigate carbon recycling.
The test remains the same:
How effectively does the complete system reduce its dependence on newly extracted fossil carbon while continuing to provide the energy and materials society requires?
That is the proposition behind Defossilisation – The Next Chapter of the Energy Transition.
It moves the conversation beyond labels and individual technologies toward something fundamentally physical:
Follow the carbon. Measure the fossil-carbon input. Then engineer it toward zero.
