Introducing a Green Revolution in Brick Making: Michelmersh’s Hydrogen-Fired Innovation


Michelmersh Brick Holdings PLC, a pioneer in the British building materials industry, is leading a remarkable transformation with its latest innovation: hydrogen-fired brick making. This breakthrough technology not only promises to revolutionize the way bricks are produced but also aligns with global sustainability goals. This article explores how Michelmersh is setting new environmental standards in the brick manufacturing sector, delving into the technology, benefits, and potential impact of this green initiative.

The Context of Innovation

The brick making industry has historically been resource-intensive, relying heavily on processes that emit significant levels of carbon dioxide (CO2). As global awareness and regulations surrounding carbon emissions tighten, the pressure mounts on industries to adopt more sustainable practices. Michelmersh’s response to this challenge is both timely and transformative, marking a significant step forward in the company’s commitment to sustainability.

Hydrogen-Fired Brick Making: How It Works

Traditional brick firing methods use natural gas or coal, producing a substantial amount of CO2. Michelmersh’s new technology replaces these fossil fuels with hydrogen, a clean-burning alternative. When hydrogen is burned, it primarily produces water vapor, eliminating CO2 emissions by 60-80% from the firing process.

Technical Details

Hydrogen Generation: Hydrogen used in the firing process is produced through electrolysis, a method that splits water into hydrogen and oxygen using electricity. Ideally, this electricity is sourced from renewable energies, ensuring that the hydrogen production itself is also sustainable.

Kiln Modifications: To accommodate hydrogen combustion, Michelmersh has innovated modifications to their traditional brick kilns. These modifications ensure that the kilns can handle the different combustion properties of hydrogen compared to natural gas.

Environmental and Economic Benefits

Reduced Carbon Footprint

By eliminating CO2 emissions during the firing stage, Michelmersh significantly reduces the overall carbon footprint of their bricks. This not only helps in fighting climate change but also positions Michelmersh favorably in a market that is increasingly sensitive to environmental impact.

Energy Efficiency

Hydrogen burns at a higher efficiency compared to natural gas. This increased efficiency can lead to reductions in overall energy use, further enhancing the sustainability of the brick-making process.

Regulatory Compliance and Market Advantage

With governments worldwide imposing stricter regulations on carbon emissions, Michelmersh’s hydrogen-fired bricks offer a competitive edge. They meet current and future regulatory standards, appealing to eco-conscious consumers and industries looking to reduce their environmental impact.

Challenges and Solution

While the shift to hydrogen-fired brick making is a significant advancement, it comes with its set of challenges.

Cost of Implementation

The initial cost of modifying existing kilns and setting up hydrogen production facilities is substantial. However, Michelmersh anticipates that the long-term benefits and the potential for governmental subsidies for green technologies will offset these initial costs.

Hydrogen Storage and Safety

Hydrogen requires careful handling and storage solutions due to its high reactivity and flammability. Michelmersh has invested in state-of-the-art storage solutions and safety protocols to mitigate these risks.

Scaling Up

Scaling this technology from pilot to full-scale production is another hurdle. Michelmersh is planning phased investments and is seeking partnerships with technology providers to scale up efficiently and economically.

The Future Impact

Michelmersh is not only transforming its own production processes but also setting a precedent for the brick-making industry at large. As this technology proves viable, it could catalyze a wider adoption of hydrogen across other sectors of heavy industry, leading to broader environmental benefits.

Industry-Wide Adoption

As other companies witness the success and benefits of hydrogen-fired brick making, industry-wide adoption could become more feasible, reducing global CO2 emissions from one of the most traditional sectors of the manufacturing industry.

Technological Innovations

The push towards hydrogen might also spur further technological innovations in brick making and beyond, including advancements in renewable energy, hydrogen storage, and safety technologies.


Michelmersh’s pioneering move to hydrogen-fired brick making is a significant step towards a more sustainable future. This innovation not only demonstrates Michelmersh’s leadership in the building materials industry but also serves as a model for other companies aiming to reduce their environmental impact. With this green revolution, Michelmersh is paving the way towards a cleaner, more sustainable future in brick making and setting the stage for the next generation of industrial manufacturing solutions.
