Technologies to Decarbonise Hydrogen Production
The challenges of the energy transition require addressing long-term solutions for reduction of carbon emissions to the atmosphere by addressing the needs for generation, storage and utilization of future energy sources.
Blue hydrogen is expected to pave the way for the future low-carbon energy solutions. Cost-effective, deeply decarbonized blue hydrogen production is available and proven today at the desired scale for both new plants and retrofits, and provides immediate solutions for carbon capture, handling and utilization. In projects converting grey to blue hydrogen plants, flue gas capture may be an attractive option for deep carbon capture and is expected to be more cost effective compared to traditional CCS applications where CO2 content in the flue gas is lower.
The paper will address the carbon intensity of various hydrogen production methods, from traditional grey hydrogen through blue hydrogen, at various capture rates, as well as the production of hydrogen in electrolysers.
