Hydrogen from eFarm
SPANGLER – the Plus of Innovation.
What is more obvious than to apply a kind of energy storage for electric power generated by renewable energy, which brings the power at any time to other sectors like traffic and industry in order to decarbonise them. Electrolysers, which convert green electricity into green hydrogen, are the technical key components for this. H-TEC SYSTEMS GmbH has developed such electrolysers (PEM process) that achieve the conversion with a degree of efficiency of up to 95%. With green hydrogen low CO2 and pollutant emissions with cars, lorries, trains, ships etc. can be achieved. For this project SPANGLER Automation has designed the switch system and the control system with process surface.
The PEM elektrolysers from model series ME100/350 are applied in Germany’s biggest green hydrogen mobility project eFarm. Many participants are involved in North Friesland with the generation of green hydrogen from wind energy which is put on the market as fuel. As the complete technology of the electrolyser is installed in a 20 feet container, a decentral application of this gas generator is no problem.
This flexibility, however, becomes obvious with the requirements to the operation. As the electrolyser can virtually be applied anywhere, the operating interface has to be designed in a way that also operators with a short training time can cope with it. Additionally, a number of assumptions and redundancies have to be considered in order to exclude the risk of possible malfunctions as the gaseous hydrogen is highly explosive. Therefore, as safety performance category Safety Integrity Level (SIL) 2 was realised. This aims at finding and minimising possible risks for customers, plants and operators in advance.
The generation of green hydrogen which is acceptable from the economic and ecological point of view, in order to apply it as fuel or storage of huge amounts of energy is one of the central challenges connected to the conversion to renewable energy generation. SPANGLER Automation helps to manage this.
