Blue Hydrogen by Membrane

1. The practice of "Net Zero by 2050" through greenhouse gas reduction is an international promise and action to make a better world to live in.

2. CO2 accounts for about 76 % of total greenhouse gas emissions. CO2 reduction is the most effective way to reduce greenhouse gases.

3. The clean fuel hydrogen market is expected to grow to $12 trillion by 2050. Steam Methane Reforming (SMR) is the most common and cost-effective method for hydrogen production, and it contributes about 50% of the world's hydrogen production.

4. Hydrogen produced by SMR is termed 'grey hydrogen' when the waste carbon dioxide is released to the atmosphere and 'blue hydrogen' when the carbon dioxide is captured and sequestered.

5. To recover and purify hydrogen, a pressure swing adsorption (PSA) technology is applied. It operates at high pressure and high temperature to separate hydrogen, and this results in high initial facility cost as well as operational cost.

6. Astroma's membrane carbon capture device is an innovative method for capturing CO2 and separating hydrogen from the gas that has passed through SMR. It operates at low pressure and ambient temperature, so the initial equipment cost and production cost are low. It is expected that the production cost of blue hydrogen is reduced by 25% to 50%, thereby increasing the competitiveness of the blue hydrogen produced with natural gas.

7. Natural gas markets in the USA, Canada, and the Middle East can benefit from the low cost of blue hydrogen production and contribute to the expansion of the hydrogen market.

8. Arstroma's carbon capture technology is already being used in the CCUS market, and with additional experiments to find out optimal conditions to apply the same technology to blue hydrogen production, it will be a promising technology to produce cost competitive blue hydrogen.
