Most major economies around the world have committed to meeting ambitious net zero targets by 2050. As a versatile, clean and safe energy carrier, hydrogen is expected to play a crucial role in the transition to net zero. Large-scale, economic production of low carbon hydrogen is essential for the mass decarbonisation process, and this is especially true for hard-to-abate sectors such as the steel, cement and chemical industries, as well as dispatchable power, domestic heating and transport. To accelerate the energy transition, Johnson Matthey (JM) has developed a unique carbon capture and storage (CCS)-enabled hydrogen production process that economically delivers very low carbon intensity hydrogen, commonly known as ‘blue’ hydrogen. The flowsheet combines a gas-heated reformer (GHR) and autothermal reformer (ATR), and provides a more energy efficient process than both conventional steam methane reforming (SMR) and flowsheets that deploy a stand-alone ATR, ultimately resulting in a higher hydrogen yield and reducing natural gas consumption. JM's GHR-ATR blue hydrogen technology makes decarbonisation via CCS easier and cheaper than using an SMR. By delivering a CO2 capture rate of over 95%, the technology provides significant benefits compared with SMR and alternative ATR technologies. Compared with conventional SMR, JM's GHR-ATR blue hydrogen technology demonstrates: Natural gas consumption – 10% lowerCO2 produced – 10% lessCapital cost for the CO2 capture system – 75% lower Use of JM's unique GHR-ATR blue hydrogen technology will future-proof and de-risk projects by minimising the impact of rising feedstock, CO2 transmission and storage costs, as well as potential governmental schemes for carbon taxation. This process will enable hard-to-abate sectors to reduce Scope 1 and Scope 2 emissions by decarbonising their operations, accelerate the energy transition by producing clean hydrogen for consumers, ensure the viability of the plant for the future, and demonstrate commitment to sustainability. JM's GHR-ATR blue hydrogen technology has been selected for deployment by HyNet North-West, the United Kingdom's first low carbon hydrogen plant. The 300 MW plant is expected to be built in the UK in 2026 (pending the final investment decision), and will provide hydrogen to industrial and eventually domestic customers. |
