Biomass as a renewable source of hydrogen

Biomass as a renewable source of hydrogen

For centuries, biomass has been one of the main energy sources used by humans. Materials such as wood, plant residues and other organic matter were traditionally burned for cooking and heating, before coal, oil and natural gas became dominant. Today, biomass is being reconsidered as a renewable raw material that can be converted into cleaner forms of energy.

Hydrogen is expected to play a key role in the energy transition, especially in sectors where electrification is more difficult, such as heavy transport, industry, and energy storage. For this reason, biomass is attracting growing interest as a renewable feedstock for hydrogen production.

Biomass includes agricultural residues, forestry waste, food by-products, algae, and other biological resources. Using these materials for hydrogen production can support both renewable energy goals and waste valorizations.

Main conversion routes

Several approaches are currently being studied:

• Thermochemical processes such as gasification and pyrolysis, convert biomass at high temperature into hydrogen-rich gases.
• Biological processes such as fermentation and anaerobic digestion use microorganisms and can work under milder conditions, especially with wet biomass, although hydrogen yields are often lower.
• Electrochemical and hybrid processes are also being explored to improve efficiency and process flexibility.

Catalysts are a key part of many of these technologies because they can improve hydrogen yield, reduce by-products and enhance process efficiency:

• Nickel-based catalysts are widely studied in reforming and gasification-related systems.
• Iron-based materials, metal oxides and carbon-based materials are also relevant as catalyst components, supports or functional materials in hydrogen-related research.

Although biomass-to-hydrogen technologies still face challenges such as energy demand, catalyst stability and scale-up, they offer an interesting route for combining renewable energy, waste valorization and process innovation.

At CymitQuimica, laboratories working on biomass conversion, catalysis and hydrogen-related research can find products to support these workflows, including nickel compounds, iron-based materials, titanium dioxide, zinc oxide, carbon materials, and other research chemicals and analytical reagents for process development and laboratory studies.
