Why You Should Switch To A Hydrogen Boiler And What It Means For Your Budget?

Energy and fuel with hydrogen emissions.

Are you looking to upgrade your home’s heating system with a more environmentally friendly option? 

Discover the revolutionary potential of hydrogen boilers in transforming how we heat our homes while reducing our carbon footprint.

These cutting-edge heating solutions have the power to transform how we heat our homes while significantly reducing our carbon footprint.

In this blog, we’ll dive deep into the world of hydrogen boilers and explore their game-changing environmental benefits. 

We understand that you may have questions about the financial aspect, such as whether hydrogen comes with a higher price tag than traditional fuels. 

Rest assured, we’ll address these concerns and provide valuable insights into the cost considerations associated with hydrogen. 

But first, let’s look at what we know about hydrogen and how it can be implemented into our heating systems. 

What is hydrogen?

Did you know hydrogen is the most abundant element in the universe?

However, here on Earth, we don’t find it readily available in its pure form. Instead, it teams up with other elements like oxygen in water or carbon in hydrocarbons.

But what makes hydrogen truly special is its impressive energy content. This means that when we burn hydrogen, it releases a whole lot of heat, making it an amazing fuel source. From heating our homes to generating electricity and even powering vehicles, hydrogen can do it all!

One of the greatest things about hydrogen is its versatility. We can make it from different substances, like natural gas and water. This opens up a world of possibilities for clean and sustainable energy.

How do hydrogen boilers work?

Hydrogen boilers are heating systems that use hydrogen gas instead of fossil fuels to provide heat and hot water. 

Unlike traditional boilers, which burn fuels that produce harmful gases, hydrogen boilers only produce water vapour when burned. This makes them a potentially carbon-neutral heating option.

Hydrogen boilers are becoming more popular as people seek ways to reduce greenhouse gas emissions. 

By using hydrogen as a fuel, they have the potential to significantly decrease co2 emissions associated with heating systems.

Myths about hydrogen boilers

Hydrogen boilers are a relatively new phenomenon. This has led to a certain amount of misinformation about how they work. 

Let’s look at some of the four most common misconceptions surrounding hydrogen boilers. 

  1. Hydrogen boilers are dangerous and prone to explosions

Like any fuel-burning or natural gas boiler, proper design, installation, and maintenance are crucial to ensure safety. 

A hydrogen-ready boiler can be engineered with safety measures to mitigate risks. They undergo rigorous testing and adhere to safety standards.

  1. Hydrogen is a rare and scarce resource.

While it’s not freely available in its pure form on Earth, hydrogen remains the most abundant element in the universe and can be produced through various methods.

  1. Converting existing gas boilers to hydrogen is costly and complicated

Retrofitting an existing gas network to run on hydrogen fuel cells can be complex.

However, many boiler manufacturers are developing hydrogen-ready boilers, making the transition easier in the future. Additionally, new buildings can be designed with hydrogen boilers in mind.

  1. Hydrogen boilers are less efficient than traditional gas boilers

Hydrogen has a high energy content, making it a potentially efficient fuel source.

While hydrogen boilers may have slightly different combustion characteristics, technological advancements aim to optimise their efficiency and performance.

Are hydrogen boilers more expensive to run?

The cost of running a hydrogen boiler can be higher than traditional gas boilers due to the current pricing and availability of hydrogen.

Estimates suggest that heating a home with green hydrogen, the most eco-friendly form, could cost around £960 per year. In contrast, running a gas boiler costs approximately £551 per year, almost half the amount.

Hydrogen boilers can also run on blue hydrogen, which is cheaper but generates more carbon emissions than green hydrogen.

Despite the higher costs, hydrogen is highly efficient in heat production. In fact, 1kg of hydrogen contains the same energy as 2.8kg of natural gas. 

This means that hydrogen boilers require less fuel compared to gas boilers to keep homes warm. This efficiency can help offset some of the higher fuel costs associated with hydrogen.

Why should you install a hydrogen boiler?

Hydrogen boilers offer several benefits that make them an excellent choice for heating systems:

Environmentally friendly

Hydrogen is a clean and renewable energy source. When used in boilers, it produces only water vapour, meaning lower carbon emissions and a positive environmental impact.

Reduced carbon footprint

A hydrogen-ready boiler can help reduce greenhouse gas emissions and combat climate change. This is important because buildings contribute a significant portion of global carbon emissions.

Energy efficiency

Hydrogen has a lot of energy packed into it, so you need less hydrogen to produce the same amount of heat as natural gas. This means you can save on fuel consumption and lower energy bills.


Hydrogen boilers can be used for different purposes, such as heating your home and providing hot water. They can be adapted to fit different types and sizes of buildings, making them a flexible heating solution.

Potential for energy storage

Hydrogen can be produced and stored for later use. This means it can balance energy supply and demand, especially with renewable energy sources. It helps create a more reliable and sustainable energy system.

Advancements in technology

Ongoing research and development are improving hydrogen technologies, including boilers. This means they are becoming more efficient, cost-effective, and safe. As the technology continues to advance, hydrogen boilers will become even better.

Overall, hydrogen boilers are a potential game-changer for home heating, reducing carbon dioxide emissions and offering versatility. Despite higher costs, they are efficient and can help save on fuel consumption.
