Coupling solid oxide electrolysis to ammonia production

LSB Industries has announced various decarbonization projects for its existing facilities in the USA, including CCS in El Dorado (Arkansas) and electrolysis-based hydrogen production in Pryor (Oklahoma). At Pryor, a dual-technology approach will be pursued, with 20 MW of alkaline electrolysis capacity to operate alongside a 10 MW solid oxide electrolyzer, with the latter electrolysers to be provided by Bloom Energy. To discuss the Pryor project and the opportunities on offer, the AEA's Kevin Rouwenhorst spoke with Jakob Krummenacher (Director of Clean Energy, LSB Industries) & Rick Beuttel (Vice President of Business Development, Hydrogen, Bloom Energy). 0:00 Welcome and introduction from Kevin 4:35 Rick Beuttel - advantages of SOEC technology and R&D with Idaho National Labs 17:50 Jakob Krummenacher - LSB's ammonia production footprint, and the Pryor SOEC project (a pdf of the speaker's slides can be downloaded here: https://bit.ly/3XGPCPl) Q&A 22:34 When would we see a GW-scale SOEC ammonia production plant? 24:55 Drivers for LSB to pursue electrolytic hydrogen production at Pryor? 28:04 Electrolytic hydrogen will supply about 10% of total requirements at Pryor - any reasoning behind this figure? 29:20 Combination of electrolysers & SMR/ATR in the future? 30:15 Opportunities to utilize oxygen by-product? 32:32 What key developments have extended the lifetime of electrolysers, especially in a commercial setting? 35:35 More oxygen by-product opportunities for LSB 37:00 Cold standby or hot standby for SOEC-coupled ammonia production? 38:27 Recommended ramping frequencies for SOEC? 39:50 How "green" can Pryor go? 41:10 Will the mix 'n match technology approach continue, and to what scale? 45:50 Materials for SOEC, and recycling old units 47:46 What impact does the energy efficiency of SOEC have on overall carbon footprint? 50:05 Different safety & maintenance concerns vs. other types of electrolysis? 54:10 Five to ten years from now, what does success look like for the Pryor (and other) LSB decarbonization projects? 55:18 Five to ten years from now, what does success look like for Bloom's engagement with ammonia production projects? 57:00 Wrap-up and next month's webinar (the HyEx project in Chile, register here via Zoom: http://bit.ly/3JayIUX) Stay up-to-date with news, analysis and future AEA events by signing up to our weekly email newsletter: https://bit.ly/3GfnavW
