Green Hydrogen Powering the Textile Industry’s Clean Energy Transition

The world's clothing industry is expanding rapidly, projected to reach $1.3 trillion by 2030 [1]. This growth, however, comes at a significant cost in terms of energy use and pollution.

This article explains how green hydrogen, a clean energy source, can help the clothing industry become significantly more sustainable by reducing carbon pollution, conserving water, and improving production processes.

Beyond environmental benefits, it offers real business advantages. We'll also cover upcoming challenges and global efforts in this critical transition.

The Big Environmental Problem with Making Clothes

Making clothes is an energy-intensive process that requires both electricity and heat at every stage. Processes such as dyeing and finishing are particularly energy-intensive, requiring substantial heat and steam. This high energy consumption leads to severe environmental impacts:

Air Pollution: The global clothing industry contributes 8-10% of all CO₂ emissions worldwide (about 1.7 billion tons annually), surpassing aviation
Water Use and Pollution: It's the second-biggest industrial water user (79 billion m³ in 2015). Producing one cotton T-shirt requires approximately 2,700 litres of freshwater. Approximately 20% of global water pollution originates from dyes and chemicals discharged by textile factories, which often contain harmful substances.
Waste: The sector discards 92 million tons of clothing waste annually, with only about 8% of new fibres from recycled materials. This waste burdens landfills and contributes to increased pollution.
Tiny Plastic Bits: Synthetic clothes shed microplastics when washed, accounting for up to 35% of all microplastics released into the environment.

It's also crucial to note that consumer habits, such as washing and drying clothes at home, contribute significantly to a garment's total environmental footprint. [2-9]

How Green Hydrogen Works in Making Clothes

Green hydrogen is a versatile tool for cleaning up various parts of textile manufacturing.

Heating and Steam: A Clean Switch

Many textile steps, such as dyeing, washing, drying, and finishing, require significant heat and steam, traditionally generated from fossil fuels. Green hydrogen offers a clean alternative, producing only water vapour when burned, thus eliminating CO₂ pollution from boilers and specialised heating machines.

Textile machinery makers are actively working on this. Monforts, for instance, launched the "WasserSTOFF" project in 2022 to develop hydrogen-heated stenter frames for carbon-neutral textile finishing [10]. While direct electric heating is suitable for some applications, green hydrogen is crucial for very high-temperature processes.

A Green Ingredient for Textile Chemicals

Green hydrogen can also be a clean ingredient for chemicals:

Hydrogen Peroxide: Widely used in textiles for bleaching and wastewater treatment, it's eco-friendly and breaks down into water and oxygen. Using green hydrogen to produce it makes the process cleaner and can lead to brighter fabrics [11].
Methanol and Synthetic Fibres: Green hydrogen can replace traditional hydrogen in the production of methanol [12]. For synthetic fabrics like polyester, using low-carbon hydrogen as fuel and an ingredient can reduce total pollution by up to 31%, and even 45% when using renewable CO₂ [13].

Making Your Own Clean Energy On-Site

Textile factories can produce green hydrogen on-site using renewable energy thereby reducing their reliance on the grid and enhancing energy security. The "WhATTer" project in Spain, for example, cleans textile wastewater while generating green hydrogen, creating a powerful synergy that makes the sector more sustainable [14].

The Benefits of Using Green Hydrogen in Textiles

Switching to green hydrogen offers the textile industry a more sustainable, resilient, and profitable future.

Better for the Environment: Less Pollution, Cleaner Water

Green hydrogen significantly cuts greenhouse gas emissions and pollution. Unlike fossil fuels, it only produces water vapour when burned, ensuring a clean energy cycle . This directly reduces the textile industry's carbon footprint.

It also fights water pollution. Projects like "WhATTer" demonstrate systems that clean toxic textile wastewater while yielding clean hydrogen, recovering water and reducing waste.

Additionally, using green hydrogen to make hydrogen peroxide for bleaching is an eco-friendly alternative to harmful chlorine-based chemicals, promoting a circular economy.

Good for Business: Money Savings and Security

Though initial costs are higher, the long-term economic outlook is promising. Green hydrogen costs are projected to decrease by 50% by 2030, potentially making it profitable, especially with declining renewable energy prices.

Governments offer substantial financial assistance, such as tax breaks in the U.S. (IRA) and large budgets in India's National Green Hydrogen Mission, to lower production costs and de-risk investments.

Relying less on volatile fossil fuel prices means more predictable energy costs and greater security. On-site production or local hubs also boost local economies and create jobs.

Better Ways to Operate: Efficiency and Quality

Green hydrogen brings operational advantages:

Reliable Energy: On-site production with energy storage ensures a steady supply, reducing reliance on the grid and providing backup.
More Efficient Energy Use: Systems running on green hydrogen (such as CHP/CCHP) can achieve energy efficiencies of 80-90%, thereby lowering costs [15].
Flexible and Adaptable: Green hydrogen is versatile, converting to electricity or synthetic gas for various industrial tasks. Its high energy density and transportability suit fluctuating demands.
Higher Product Quality: Using sustainably produced hydrogen peroxide for bleaching yields superior fabric quality, including brighter whites and more vibrant colours.

Real-World Projects Making a Difference

Many projects demonstrate practical applications:

Textile-Specific:

Monforts' "WasserSTOFF" project in Germany is pioneering the development of hydrogen-heated textile machinery, specifically focusing on stenter frames. This initiative aims to enable carbon-neutral textile finishing by investigating the use of hydrogen, or hydrogen/natural gas mixtures, as an alternative fuel for drying and fixation processes, thereby significantly reducing CO2 emissions from these energy-intensive operations.
Spain's "WhATTer" project offers an innovative electrochemical system that simultaneously cleans textile wastewater and generates green hydrogen. This dual-purpose technology not only tackles the challenge of textile effluent treatment, removing difficult-to-biodegrade dyes and pollutants, but also produces a valuable energy by-product in the form of green hydrogen, fostering a powerful synergy for circularity and reduced reliance on fossil fuels within the sector.
The UK's Project Re:claim is a commercial-scale polyester recycling plant that utilizes hydrogen power for its operations. This groundbreaking venture transforms post-consumer garments and other polyester textiles into raw materials, driving the industry towards a circular economy. By employing hydrogen power units (HPUs) from companies like GeoPura, the plant ensures zero-emission electricity generation during the recycling process, effectively replacing high-polluting diesel fuels, especially while awaiting grid connection. [16]

These initiatives demonstrate the rapid transition of the green hydrogen economy from concept to reality, laying the groundwork for widespread adoption.

Investing in the Green Future

Green hydrogen investments surpassed $150 billion in 2023. The market, valued at $1.1 billion in 2022, is projected to reach $72 billion by 2030, with a 55% compound annual growth rate (CAGR) [17]. This growth is driven by:

Cheaper Renewable Energy: The costs of solar and wind energy have dropped significantly.
Better Technology: Innovations make electrolysers cheaper and more efficient.
Government Help: Tax breaks and grants encourage projects.
Bigger Scale: Increased investment lowers production costs per unit.

While the initial investment focuses on ammonia, refining, and methanol, the textile industry's growing need for clean energy and ingredients makes it a promising area for future green hydrogen investment.

Conclusion and What's Next: A Sustainable Tomorrow

The textile industry must decarbonise, and green hydrogen offers a vital path to sustainability. Produced with renewable energy, it drastically cuts carbon emissions, unlike fossil fuels.

We've seen its versatile use in textile factories, where it replaces dirty fuels for heating and steam, serves as a cleaner chemical ingredient, and even cleans wastewater while producing more hydrogen.

These applications promise significant environmental benefits, including reduced CO₂ emissions and cleaner water. Economically, future price drops, government incentives, and energy security suggest long-term profitability. Operationally, it means reliable, efficient, and flexible energy, resulting in improved product quality.

Global initiatives, substantial funding, and pilot projects demonstrate a strong commitment to this endeavour. As green hydrogen costs fall and technology improves, it will become even more attractive. Growing consumer demand for sustainable products further pushes this transition.

Ultimately, the full integration of green hydrogen requires sustained investment, strong partnerships, clear government regulations, and dedicated infrastructure development.
