Résumé
Technological conclusions: At the beginning of the new millennium, hydrolysis of sodium borohydride (NaBH4) was presented as a promising on‐board technology to generate H2 for light‐duty vehicles. Years later, other B(−N)−H compounds (e.g., lithium borohydride (LiBH4) and ammonia borane (NH3BH3)) emerged as attractive alternatives whereas NaBH4 was struggling with several issues jeopardizing its implementation. The technological readiness of the promising hydrolytic B(−N)−H compounds is investigated in this Review. It is concluded that NaBH4 is the best hydrolytic B(−N)−H compound for implementation on a large scale, with a few key challenges left to address in the future. More details can be found in the Review by Umit B. Demirci of the University of Montpellier on page 470 in Issue 3, 2018 (10.1002/ente.201700486).
