Scaling solutions for the new energy reality

The global energy system is entering a new phase – shaped not only by climate ambition, but by a renewed surge in demand for reliable and affordable energy.

Geopolitical disruptions, supply-chain concentration and growing energy demand are reshaping how countries think about energy security, industrial competitiveness and decarbonization.

At the same time, digitalization, electrified mobility and broader economic growth are driving power demand upward at remarkable speed, often in highly concentrated locations. After nearly two decades of relative stability, electricity demand in the United States is projected to grow again. Similar dynamics are unfolding across Europe and parts of Asia.

According to BloombergNEF, U.S. data center power demand alone could rise from roughly 35 gigawatts in 2024 to more than 100 gigawatts by 2035.

The challenge facing energy systems is clear but profound: deliver more energy – reliably, affordably and at scale – while continuing to reduce greenhouse gas emissions and strengthen system resilience in an increasingly volatile world.

Expanding the energy toolkit

The energy transition will involve replacing higher-emissions energy sources while also expanding the portfolio of technologies and fuels that power modern economies. Managing that shift requires balancing availability, affordability and decarbonization – the core dimensions of the global energy trilemma.

Renewables and electrification will continue to play a central role. But as energy demand accelerates, the system will increasingly rely on a broader set of solutions, including e-fuels, renewable fuels and low-carbon fuels.

The result is a more diversified energy system in which multiple technologies contribute to reliability, affordability and long-term emissions reductions.

Power demand and fuel diversification

Rising electricity demand – particularly from AI and data centers – is adding new pressure on power systems that are already facing grid constraints in many regions.

The challenge is not only deploying more clean energy, but ensuring the system has the capacity and infrastructure to meet rapidly growing demand.

We clearly need more renewable electricity generation and stronger grids. But we also need to expand the pathways through which energy is produced and delivered.

Not all sectors can run directly on electricity. In many parts of the economy – from aviation and shipping to chemicals and heavy industry – energy will continue to be used in the form of fuels and molecules.

This is where diversified fuel pathways will play an increasingly important role.

Topsoe technologies and catalysts help customers produce fuels and chemicals more efficiently, and solutions such as SynCOR, HydroFlex, SOEC and eREACT support the production of e-fuels, renewable fuels and low-carbon fuels that cut emissions and diversify energy supply.

By converting electricity into hydrogen and other molecules, these technologies create flexible energy carriers that enable the production of fuels for sectors that cannot easily electrify directly.

Efficiency will be critical. Topsoe’s high-temperature SOEC electrolyzer produces more hydrogen per unit of power input than conventional electrolyzer technologies. SOEC achieves around 20% higher efficiency – rising to as much as 30% when integrated with steam – enabling greater hydrogen output from the same amount of electricity. In a power-constrained world, that efficiency advantage matters.

Scaling solutions that deliver

Parts of the clean fuels market are moving from early momentum toward large-scale deployment.

Higher capital costs and policy uncertainty have slowed investment decisions for some projects. Moving viable projects to final investment decision – and ultimately into operation – will be essential for maintaining momentum and building investor confidence.

At the same time, the need to diversify fuel supply remains clear. Across sectors, companies are investing in technologies that improve efficiency, expand feedstock flexibility and enable the production of new fuels.

Refineries are upgrading to produce advanced fuels more efficiently, industrial producers are integrating hydrogen and ammonia into their operations, and aviation is working to scale sustainable fuels to support long-term growth.

For technology providers, this shift underscores the importance of solutions that can deliver performance at industrial scale – from refining and advanced fuels to renewable fuels, carbon capture and clean hydrogen.

At Topsoe, we help customers deploy and scale these technologies across the energy spectrum. Our portfolio spans catalysts and advanced refining systems that improve efficiency, as well as hydrogen, ammonia and sustainable fuels – helping strengthen resilience, support industrial competitiveness and advance the energy transition.

Diversification and balance

As these technologies advance, diversification is becoming a strategic imperative for energy systems.

Recent geopolitical disruptions and supply-chain volatility have underscored the importance of resilience. Economies that broaden their energy mix – combining conventional strengths with advanced technologies and cleaner fuels – will be better positioned to manage risk, stabilize costs and sustain industrial competitiveness.

The new energy reality ultimately requires balance: more generation and stronger grids, greater efficiency, and diversified fuel pathways supported by continued innovation.

Those that successfully combine diversification, competitiveness and decarbonization will build the most resilient energy systems – and shape the global energy landscape in the decades ahead.
