Dispelling Myths

When it comes to decarbonisation, steam often gets a bad reputation.

There’s a growing misconception that to achieve net-zero, industries must move away from steam entirely – a process sometimes dubbed “desteaming.” But here’s the truth: steam isn’t the problem; It’s the fossil fuels that have traditionally been used to generate steam that are. In fact, with the right updates and technologies, steam systems can play a central role in a low-carbon future.

At Spirax Sarco, we believe it’s time to set the record straight.

❌ Myth: Steam is Outdated and Incompatible with Net-Zero

Steam has been the backbone of industrial heating for over a century. It’s trusted, efficient, easy to control and distribute and incredibly versatile – which is exactly why it’s still widely used across sectors like food & beverage, healthcare, pharmaceuticals, and manufacturing.

What’s often misunderstood is that steam systems themselves aren’t inherently inefficient. It’s how they’re managed, maintained, and powered that makes the difference.

✅ Fact: Steam Can Be Decarbonised – Without Being Replaced

Modern steam systems are nothing like those of decades past. Today, businesses can make huge strides towards net-zero while continuing to use steam, by adopting smarter, cleaner practices such as:

• Electrifying steam generation using renewable electricity
• Installing energy-efficient components like precision control valves, insulation, and flash steam recovery systems
• Digitally monitoring steam traps to prevent losses and keep systems running at peak performance
• Recovering waste heat to reduce overall energy demand

These solutions don’t require a complete overhaul. They work with the existing infrastructure you already have – and they deliver measurable savings in both emissions and operating costs.

🌍 Why “Desteaming” Isn’t Always the Answer

Removing steam entirely often comes with unintended consequences: large capital expenditure, longer payback periods, costly and intrusive building, pipework and process modification and the introduction of alternative systems that may still rely on fossil fuels at some stage of the process.

For many businesses, it's far more practical – and sustainable – to optimise what’s already in place.

At Spirax Sarco, we’re helping customers decarbonise without compromising performance, safety, or reliability. Whether it's a dairy looking to cut emissions or a hospital needing guaranteed sterilisation, steam remains one of the most effective ways to deliver heat – especially when it's used wisely.

💡 The Bottom Line

Ditching steam isn’t a prerequisite for going green.

With the right upgrades, maintenance, and control, steam systems can absolutely support your decarbonisation strategy – and in many cases, outperform newer alternatives in both efficiency and environmental impact. The FIRST step is to reduce demand for steam by following best practice with steam generation & distribution and then seek to understand the process.

Let’s stop writing steam off – and start working with it to build a cleaner, more sustainable future.
