The solar hydrogen station is located on the grounds of the Saitama Prefectural Office in Japan, as part of a collaboration between Honda, industrial group Iwatani and the Saitama Prefecture. 

It uses a high pressure water electrolysis system, developed by the carmaker, which removes the need for a mechanical compressor and produces 1.5kg of hydrogen per 24 hours – enough to provide a 90-mile range for the FCX Clarity.

Most notably, though, the system is the first in Japan to emit zero CO2 as a result of the production, storage and dispensing of hydrogen from water, and Honda hopes to develop a downsized version for home use.
