Innovative System Produces Pink and Grey Hydrogen Simultaneously
N/A, Monday, 13 January 2025.
Discover how a new system combines nuclear reactors and electrolyzers to produce hydrogen more efficiently, reducing costs by 40% and cutting carbon emissions significantly. It’s a game-changer in energy!
Revolutionary Dual Production System
I’m excited to share details about a groundbreaking hydrogen production system that’s just been unveiled. The system cleverly combines a high-temperature gas-cooled reactor (HTGR) with a high-temperature electrolyzer to simultaneously produce both pink and grey hydrogen [1]. What makes this particularly interesting is that the HTGR operates at an impressive 850°C core temperature, channeling 600 MW of heat to generate 258 MW of electricity [1].
Impressive Production Capabilities
The numbers here are truly remarkable. The system can produce more than 3.04 kg/s of both pink and grey hydrogen [1]. To put this in perspective, traditional hydrogen production methods using steam methane reforming and coal gasification typically result in significant carbon emissions of 10.1 to 26.1 kgCO2/kgH2 [1]. In contrast, this new system achieves a carbon footprint of less than 1.0 kgCO2/kgH2 [1] - that’s a dramatic improvement for our environment!
Economic Benefits
Let’s talk about the economics, because they’re quite compelling. The system produces hydrogen at a cost that’s 40% lower than producing pink hydrogen alone [1]. Breaking down the numbers: while pink hydrogen typically costs $6.11/kg, grey hydrogen through this system can be produced for as low as $1.14/kg using autothermal reforming [1]. This is particularly impressive when compared to other nuclear-based methods, such as sulfur-iodine and copper-chlorine water-splitting cycles, which cost approximately $2.7/kgH2 [1].
Future Implications
This innovation represents a significant step forward in sustainable hydrogen production. The system’s ability to utilize oxygen from the electrolyzer for natural gas reforming, while simultaneously leveraging water vapour and electricity from the HTGR system [1], showcases an elegant integration of multiple processes. As we move forward in 2025, this development could be crucial in making hydrogen a more viable clean energy carrier.
