LCH™ Process for the production of blue hydrogen

There is an urgent need to limit the rise in global temperatures to avoid severe environmental and societal impact. Many countries across the world have committed to zero emission targets being met by 2050, this timeframe is now only one typical syngas plant lifetime away.

The provision of decarbonised hydrogen at scale is an essential step to achieve this. Johnson Matthey’s (JM's) LCH™ technology enables decarbonised hydrogen to be produced at scale now, in the most sustainable manner.

The LCH process is the most profitable process for the production of low carbon hydrogen because, as a minimum whether compared to SMR or ATR, it:
• Utilises 10% less natural gas feedstock than competitive processes;
• Generates 10% less CO2 to be sequestered as a result; and
• Has the most intensified plant footprint of available technologies.

In this document JM’s LCH process is introduced, providing details of its key features. In addition, a comparison to a Steam Methane Reformer (SMR) with equivalent CO2 capture is provided. This technology was used by the UK Government Department for Business, Energy and Industrial Strategy (BEIS) when reviewing low carbon hydrogen production routes. The comparison reveals that JM’s LCH technology offers; lower cost, higher CO2 capture rate, improved scalability and feedstock flexibility.
