2010 | Solar Hydrogen Station
Honda began operation of a next generation solar hydrogen station prototype , designed as a single, integrated unit to fit in the user's garage at the Los Angeles Center of Honda R&D Americas, Inc. in January 2010. The next-generation Solar Hydrogen Station is small enough to fit in a typical household garage. To produce high-pressure hydrogen, the previous station required not only an electrolyzer but also a separate compressor unit. For the next-generation Solar Hydrogen Station, Honda developed a new high-differential pressure electrolyzer that combines electrolysis and compression functions in a single unit.
Since a separate compressor is no longer necessary, the Solar Hydrogen Station is more compact, quieter and lower in cost, making home hydrogen supply a more realistic option going forward. In addition, the new system is 25 percent more efficient than the previous system. Thanks to its enhanced design, the next-generation Solar Hydrogen System can produce 0.5 kg of hydrogen in 8 hours, enough to power the FCX Clarity fuel cell electric vehicle 30 miles.
