Hidrógeno – La energía del futuro

El hidrógeno es considerado como una de las fuentes de energía más importantes del futuro. En vista de la escasez de recursos energéticos, las aplicaciones de hidrógeno ya ofrecen una alternativa tecnológica real a las soluciones convencionales.

El mejor ejemplo es la pila combustible. En las pilas de combustible el hidrógeno y el oxígeno se combinan para formar agua liberando una gran cantidad de energía. De esta manera las pilas combustibles se pueden utilizar en vehículos como una alternativa ecológica al motor de combustión convencional. WITT ofrece para ello válvulas de seguridad especiales que garantizan la seguridad protegiendo el sistema de hidrógeno contra peligrosas sobrepresiones. La válvula de WITT fue la primera en cumplir con la exigente directiva europea EX 79/2009 y está homologada para la instalación en coches y autobuses.

WITT dispositivos de seguridad no se encuentran solamente en aplicaciones móviles. También en calentadores modernos con pila de combustión se integran soluciones de WITT - en forma válvulas antirretroceso de llamas o válvulas antirretorno de gas.  Para el beneficio del medio ambiente y de la seguridad.

Las aplicaciones del hidrógeno ya ofrecen una alternativa tecnológica real

Hydrogen as an energy carrier

Example: Fuel cell
The best example here is the fuel cell. In fuel cells, hydrogen and oxygen combine to form water, thereby releasing a large amount of energy. Fuel cells can therefore be used as an environmentally-friendly alternative to conventional combustion engines in motor vehicles. WITT offers special pressure-relief valves for this, these ensuring safety while protecting the hydrogen system against dangerous overpressure. The WITT valve was the first to fulfill the high requirements of Regulation EC 79/2009 valid throughout Europe and is approved for installation in passenger cars and buses. WITT safety technology can also be found in the latest fuel cell heating appliances - in the form of high-quality flashback arresters or gas non-return valves / check valves.

Example: Power-to-gas
Power-to-gas applications involve the production of hydrogen by means of water electrolysis  or methane reforming using electricity generated by renewables. Among other things, the hydrogen serves as an energy storage medium and can be used later to generate energy as required. It is already used as back-up power banks as an alternative to diesel generators. There are also schemes to blend hydrogen into methane grids for domestic heating systems.

Hydrogen as a raw material

Example: E-Fuels
E-fuels are often understood to be synthetically produced fuels. They can be used to run combustion engines without having to resort to fossil fuels. Hydrogen from renewable sources is a possible raw material here. This process, known as Power to Liquid, makes it possible to produce a crude oil-like substance from hydrogen, which then forms the basis for 'synthetic' diesel fuel.

Example: Chemical industry
In the chemical industry, hydrogen is used as a raw material. In particular, green hydrogen can be used to produce ammonia or methanol, replacing natural gas.

Hydrogen as a process gas

Example: Semiconductors
Hydrogen often plays an important role in semiconductor production. For example, for 'cleaning' the fibre optics with a deuterium (hydrogen isotope) mixture. Or in copper-wire bonding, where hydrogen as part of the protective atmosphere increases the process quality. In both applications special WITT gas mixers ensure the necessary precision of the gas mixture.

Example: Metal working
Hydrogen is a popular gas in metal processing, for example as a protective gas in heat treatment of metals or in special autogenous welding applications. Here WITT flashback arrestors ensure the highest level of safety when handling this high-energy fuel gas.

Example: Steel and glass production
Huge amounts of CO2 are still generated in steel production and glass melting. Green hydrogen is increasingly being used in these applications instead of coal or natural gas, providing significant net reduction it would be a significant gain in terms of emission-free production. Hydrogen also plays a key role in annealing processes.
