KBR review backs Syntholene's geothermal hydrogen economics for eSAF…

KBR's independent review validates Syntholene's geothermal-integrated hydrogen production economics, projecting levelised cost of hydrogen at $1.75–$2.10/kg depending on deployment conditions, with hydrogen identified as the dominant cost driver in synthetic aviation fuel production. If you make hydrogen electrolysers, compressors, heat-recovery systems or anything else that sits between a geothermal plant and a fuel synthesis reactor, Syntholene just proved there's a buyer willing to pay for your piece of this puzzle—and they're now running a live facility in Iceland to prove it works. The cost floor for green hydrogen just moved; anyone selling into eSAF production needs to know what $1.75/kg means for their margin.
