The group of Noriyoshi TSUKITA at Tohoku University has produced hydrogen from Tamagawa Hot Spring water at Semboku by reacting it with aluminum at 50 °C. The Tamagawa hot spring water has pH 1. As expected, no carbon dioxide was developed. As this and other hot springs spit with about 9000 l per spout, this technique might be used to produce small amounts of hydrogen locally. According to government plans for a hydrogen society”, the current production of 200 tons of hydrogen per year might be scaled-up to 300,000 tons in 2030.”
