Barclays says energy transition will add fuels, not replace them
In the United Kingdom, Barclays said in a February 2026 report that the global energy transition is evolving less as a clean break from fossil fuels and more as a vast expansion of the energy system, where new sources such as renewables, hydrogen, ammonia and methanol are added alongside existing fuels to meet rising demand.
The report argues that the central investment story is shifting away from headline technologies like wind and solar and toward the infrastructure that connects them. Power grids, mining, transmission systems, storage and industrial capacity are emerging as the system’s real bottlenecks and therefore the likely magnets for capital.
Global energy demand continues to rise, driven by industrial growth, artificial intelligence computing and expanding economies. Rather than replacing older fuels outright, the report says energy systems historically evolve by layering new sources onto existing ones, meaning fossil fuels remain deeply embedded even as cleaner technologies scale.
The analysis also highlights the growing role of molecular fuels alongside electricity. Ammonia, methanol, hydrogen and synthetic fuels are expected to serve sectors such as shipping, aviation and heavy industry where electrification alone cannot easily deliver the required energy density or storage.
For investors, Barclays concludes, the next phase of the transition will hinge less on generation technology and more on solving the physical constraints of energy systems.
