Hydrogen (H2) sensors are a key part of the growing Green Energy infrastructure. A highly explosive gas, Hydrogen is used in fuel cell vehicles including forklifts and automobiles. Hydrogen is also produced during lead acid battery charging and must be monitored in battery backup rooms and related facilities. The danger of hydrogen arises from its potential for explosion when it builds up without ventilation. There is a strong need for Hydrogen sensors which have long lifetimes and stability, making N5 Sensors an ideal choice for Hydrogen sensing applications. Reliable, cost effective Hydrogen sensors will enable the continued adoption of Green technologies.
