Hydrogen

Safety Solutions for Hydrogen

Hydrogen will be crucial in the future energy mix, supporting energy security and lower-carbon systems. Its production and transport pose unique safety challenges due to its explosive range, low ignition energy, and high diffusion rate. PROTEGO® offers specialized Flame Arresters Corta-chamas Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. and Breather Valves Válvula de vácuo e de alívio de pressão A pressure and vacuum relief valve is a pressure equalization valve for impermissible pressure and vacuum in a closed system. for hydrogen ensuring tailored safety solutions for project needs.

Ammonia as a Hydrogen Carrier

Ammonia is widely used as an effective means to transport and store hydrogen. In this configuration, safety considerations extend beyond the hydrogen itself to the associated tank systems and venting arrangements.

An example ammonia storage tank configuration illustrates the placement of Pressure and Vacuum Relief Valves, In-Tank Valves, and in-line Detonation Flame Arresters as part of an integrated safety concept.

Applications for 
Electrolysis Processes

System safety and personnel protection are top priorities during hydrogen production and transport. Hydrogen forms highly flammable and explosive mixtures with air, having low ignition energies and small safe gap sizes.
The explosion Explosão Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. risk increases with higher oxygen concentrations, such as in electrolysis processes. Safety devices are selected based on the specific hydrogen–oxygen concentration. Engineering ensures protection measures align with actual operating conditions.
