Blue hydrogen as a bridge to green
Steam methane reformers consume natural gas to make grey hydrogen and they emit carbon dioxide as a consequence. In the long term, that can be mitigated with a transition to ‘green’ hydrogen production using electrolysers which can be fed with renewable electrical power or steam methane reformers fed with renewable biogas. In the short-term retrofitting carbon capture to steam methane reformers (SMR), autothermal reformers (ATR) and gasification reactors to make so-called ‘blue hydrogen’ will make a big difference. Whether the carbon dioxide is captured and utilized (CCUS), or captured and stored (CCS) in permanent underground storage will in some way depend on the use-cases that are developed and commercialised. On the 27th of January the European Parliament voted that blue hydrogen produced on SMRs from natural gas with CCS will be an acceptable bridge on the journey to full decarbonisation with green hydrogen. This must be one of the most important hydrogen policy decisions that ha
