-Systems rings in new biomethane-powered fuel cell

(6/15/2007)

For the first time in Europe, biomethane will soon be used to operate a stationary fuel cell system. All the preparations for this unique event are already in place. The HotModule, as the fuel cell system from Ottobrunn-based CFC Solutions GmbH is known, was installed on the customer site in May 2007. In conjunction with an absorption refrigeration unit, it provides an electricity and refrigeration package to ensure reliable operation of the servers in a T-Systems computer centre in Munich.

‘Biomethane’ is the name given to purified biogas. Regular biogas, such as can be obtained from the digestion of compostable waste, usually has a methane content of only one-half to two-thirds, but biomethane has a methane content of around 96%, giving it the same ‘degree of purity’ as natural gas. This means it can be transported mixed with natural gas in the same network, and it can be traded in the same way as green electricity.

Biogas generation and fuel cell operation spatially independent. This yields two advantages for utilisation in the HotModule. Firstly, the CO2-neutral fuel can be produced at any desired location, which allows biogas production to be decoupled from biogas consumption; and secondly, the cost of gas purification at the HotModule can be reduced significantly because biomethane and natural gas have a much lower concentration of sulphur compounds than regular biogas. Sulphur is harmful to the HotModule’s nickel catalyzer, and it must be filtered out by a gas treatment stage if biogas or sewer gas is used directly.

The biomethane for the HotModule in the T-Systems computer centre is produced in a plant belonging to Aufwind Schmack GmbH Neue Energien in Pliening. The plant processes energy crops, which makes CO2-neutral energy supply possible because the crops absorb the same amount of CO2 while they are growing as is released when the biomethane is burnt. This is the first plant in Germany that feeds biomethane into the network in compliance with the Renewable Energy Sources Act. The customer for this fuel is E.ON Bayern AG, which resells it in the same manner as green electricity, in this case to PASM Power and Air Condition Solution Management GmbH & Co. KG. This subsidiary of Deutsche Telekom AG is responsible for energy procurement for the Group, which includes the Munich computer centre.

‘Feeding biomethane into the natural-gas network marks a quantum leap for climate protection in Bavaria and all of Germany’, said Dr Werner Schnappauf, Bavarian Minister of State for People and the Environment, on the occasion of the dedication of the Pliening biomethane plant in May. ‘What’s more, the production of biomass, biogas and bio-natural gas is a purely national value creation chain, which means it creates jobs in Germany’, according to Michael Glos, German Federal Minister for Economic Affairs and Technology, in his speech on the occasion of the dedication.

Pourquoi pas . Je pense néanmoins que le Green ou l'environmental passe par différents sujets. La consommation de ressources considérées comme écologiques en est un , mais aussi des sujets qui peuvent réduire la consommation d'énergie tel de nouveaux matériels ou des rendements améliorés.

Si ce sujet interesse, il sera rajouté à la liste des forums.

Merci de vos contributions pour en déterminer l'intéret.

Pour information, il est souhaitable que les contenus soit en Francais ou qu'il soient commentés pour en permettre la lecture par tous

Ce serait sympa d'avoir un chapitre spécifique au PUE ou Green Datacenter
C'est devenu en quelques mois un sujet de préoccupation important.
