Hydrogen firing of ceramic water filters

Adding hydrogen to natural gas is a way to reduce carbon emissions and decrease the national carbon footprint. To this end, the UK government currently plans to add up to 20% hydrogen to the existing natural gas infrastructure. Hydrogen and natural gas blends bring different combustion by-products into the kiln environment, which may affect product characteristics.

A set of water filters was sintered in a 20% blend following the same sintering profile utilised in a traditional gas kiln. The objective was to assess the fired properties of the product, specifically flexural strength, permeability, and shrinkage, when fired in an enriched hydrogen environment versus 100% natural gas.

Authored by Chris Thompson, the work was undertaken at The AMRICC Centre on behalf of MICG partners Mantec Technical Ceramics Limited and Lucideon, and was supported and partly funded by UK Research and Innovation through the Strength in Places Fund Programme.
