Decarbonisation technology shifts from niche to core of industrial strategy with rising market value

Decarbonisation technology has moved from the margins of energy strategy to the centre of industrial planning. According to the International Energy Agency, the global market value of clean energy technologies reached nearly US$1.2 trillion in 2025 and could almost double by 2035, depending on policy choices. Grand View Research separately estimates the wider decarbonisation market will reach US$4.06 trillion by 2030, underlining how quickly deployment is being commercialised across power, transport, buildings and heavy industry.

For industrial decarbonisation professionals, the message is increasingly clear: the transition will not be delivered by a single breakthrough, but by a portfolio of technologies working in concert. The 2025 literature on hard-to-abate sectors, including work published in Nature Reviews Clean Technology, stresses that iron and steel, cement and primary chemicals require a mix of efficiency gains, electrification, recycling, bioenergy, carbon capture and storage, hydrogen and alternative feedstocks. Those sectors accounted for roughly 17% of global emissions in 2021, making them a critical test of whether net-zero targets can be met in practice.

The strongest near-term momentum is still in renewable power and electrification. The IEA says falling costs are making solar, wind and storage progressively more competitive with fossil-fuel generation, while Goldman Sachs has noted that batteries and solar are scaling and cheapening faster than several other pathways. That matters because clean electricity is the platform on which much of the rest of the transition depends, from low-carbon heat in factories to electric vehicle fleets and building retrofits.

But the industrial sector’s hardest challenges remain unresolved. Carbon capture, utilisation and storage continues to be seen as essential for cement, chemicals and parts of the steel value chain, especially where process emissions cannot be eliminated by electrification alone. Grand View Research values the CCS market at US$3.9 billion in 2025, with growth to US$6.7 billion by 2033, reflecting rising investment and tighter emissions regulation. At the same time, the IEA’s 2026 outlook points to CCUS and green hydrogen as central to decarbonising cement and methanol production, where direct substitution is often impractical.

Hydrogen remains strategically important, but its economics are still uneven. Goldman Sachs has argued that hydrogen-dependent technologies are lagging behind solar and batteries on cost and scale, and that local supply chains and policy support will shape how quickly they mature. Even so, a 2025 study on cement and methanol co-production in China suggests that combining renewable-powered hydrogen with CCUS could reduce abatement costs to US$41-53 a tonne by 2035, hinting at the value of integrated systems rather than isolated technologies.

That systems perspective is increasingly shaping investment decisions. The most credible decarbonisation pathways now combine low-cost electrification where it is feasible, carbon removal or capture where it is not, and materials innovation to reduce the volume of carbon-intensive inputs in the first place. For industrial operators, the practical question is less whether decarbonisation will happen than which mix of technologies can cut emissions at acceptable cost, with acceptable risk, and on a timeline that matches regulatory pressure and customer demand.

The scale of the opportunity is large, but so is the execution challenge. In industrial decarbonisation, competitive advantage is likely to accrue to firms that can move early on capital planning, grid access, hydrogen sourcing, capture infrastructure and process redesign. The technology base is broadening quickly; the constraint now is deployment.
