How Cleaner Energy Tech is Boosting Rolls-Royce's Profits

Rolls Royce (RR) ​​​​​​​reported its operating profits surging 50% and free cash flow reaching £1.6bn (US$2.13bn), outperforming even in the face of supply chain constraints, inflationary pressure and tariffs. 

At the heart of this resurgence is a sharpened focus on efficiency, low-carbon technologies and long-term resilience, all of which are accelerating the company’s shift towards more sustainable operations and value creation.

Low-carbon energy solutions

A vital component of RR’s sustainability efforts is its SMR (Small Modular Reactor), selected as the exclusive provider for the UK’s Great British Energy – Nuclear (GBEN) programme.

This initiative aims to integrate three SMR units, with the first connected to the grid by the mid-2030s, projecting positive cash flow by late 2025 and full profitability by 2030.

An investment from ČEZ Group, a Czech utility operator, not only delivers capital but enhances nuclear expertise and prospects for European expansion.

The SMR programme, if scaled, could be pivotal in reducing reliance on fossil fuels and accelerating national net zero targets.

“Our multi-year transformation continues to deliver,” says Tufan Erginbilgic, CEO of Rolls Royce.

“Our actions led to strong first half year results, despite the challenges of the supply chain and tariffs. We are continuing to expand the earnings and cash potential of Rolls-Royce. 

“We also delivered continued strong operational and strategic progress in the first half of 2025.

“A strong start to the year gives us confidence to raise our guidance for 2025. 

“We see these targets as a milestone, not a destination, with substantial growth prospects beyond the mid-term.”

Battery storage and green technologies

RR is also advancing battery energy storage systems (BESS), with major orders including from Lithuania’s Ignitis Group. 

This business is now supporting revenue growth across the Power Systems division and is on course to reach breakeven in the near term. 

The company anticipates 20% annual revenue growth in its power generation segment, supported in part by growth in data centre power demand.

Beyond hardware, RR is embedding sustainability into product development. 

The next-generation engines under development are expected to offer lower emissions and improved fuel efficiency, with entry into service by 2028. 

In parallel, military engine upgrades with higher power density also reflect a focus on energy performance and environmental impact.

Progress in sustainability goals

RR is implementing various initiatives to bolster its sustainability profile.

To date, RR has achieved its aim to reduce energy use in operations and facilities by 50%, normalised by revenue and its ambition to achieve a GrandMean in Gallup’s top quartile (75th percentile) for large manufacturing companies by the end of 2023.

So far, the company is making key progress on:

• Delivering a 46% reduction of GHG emissions from operations, facilities and product testing by 2030 vs 2019 baseline, so far its 46%
• Achieving a Total Reportable Injury (TRI) rate of 0.33 per 100 employees by 2025, so far its 0.32
• Inspiring 25 million of  young innovators by 2030, 45% to date
• Reducing total solid and liquid waste in operations and facilities by 25%, normalised by revenue, so far 65% has been achieved
• Increasing the recycling and recovery rate to 68% by 2025 whilst maintaining zero non-hazardous waste to landfill, so far 60% has been reached.

RR’s initiatives were introduced in 2015, based on its 2014 performance, to help the company manage risk and reduce emission and cost across the company.

Sustainable aviation

In civil aerospace, RR is making strides in enhancing fuel efficiency and engine durability, key factors in decarbonising aviation.

The company completed compatibility testing of 100% SAF on its civil aero engine types, fulfilling a commitment to prove technology barriers to 100% SAF use are non-existent.

Other major highlights in the company’s progress include:

• Trent XWB-84EP: Now in service, this upgraded variant improves fuel consumption by over 1% and extends engine lifespan.
• Trent 1000 TEN: The new high-pressure turbine blade will more than double its time on wing, reducing waste and emissions associated with engine maintenance.
• Trent 7000 and 1000: Set to deliver a further 30% time-on-wing benefit by year-end 2025.

These enhancements are driven by data analytics and digital engineering. 

“This is an important milestone, not just for Rolls-Royce, but also for the wider civil aerospace industry,” says Simon Burr, Group Director of Engineering, Technology and Safety at Rolls-Royce plc.

“We hope the success of these tests provides a level of technical validation that supports those who seek to invest in the production of 100% SAF going forward.”
