Showroom for Hoppecke energy store


HOPPECKE Energiespeichersysteme

Since 1927 HOPPECKE has been developing and producing energy storage systems. Many of the developments made have been ground breaking in the industrial battery market. Today, HOPPECKE is the largest manufacturer of industrial batteries, systems and charging equipment in Europe. This comprehensive range of battery products is complemented by the most modern charging technology and monitoring equipment to create complete systems. The increasing use of renewable energy and the conversion to emissions-free drives has made rechargeable energy storage units increasingly important. HOPPECKE has developed marketable designs for the future and is making an important contribution to solving the commercial challenges we must address in the face of global climate protection goals.

Challenge and project:

To demonstrate the newest renewable energy technologies, Hoppecke needed a demonstration container, which had to meet many safety, fire and explosion protection requirements. This two-part demonstration container, designed to act as a showroom for the customer's company, needed to allow the sensitive storage of hydrogen bottles for the operation of fuel cells and also the storage of lithium-ion batteries, which were to be charged via the fuel cells and the photovoltaic panels fitted on the roof.

The solution:

DENIOS designed a two-part technical / safety room for these complex customer requirements. The two areas were separated by an F90 wall. The left hand area was used as a technical room for batteries and fuel cells; the right hand area was used as a gas cylinder storage area for the hydrogen cylinders. A frame was constructed on the roof for the customer to fit photovoltaic equipment. All doors were fitted with door hold-open devices. The technical room did not need to be explosion proof according to the customer requirements. DENIOS provided an anti-static floor. In order to look after the fuel cells correctly, several ventilation bricks were included in the design. In addition, the technical room had a 1 wing door and wiring ducts running round the ceiling. In the hydrogen storage room a stud plate floor was fitted. Lighting and the light switch were in an Ex proof design. An additional fan in the floor area ensured optimum safety. Although the lower Ex limit for hydrogen is 4%, the fan would be activated by the gas detector at 1%. The customer had specified in the risk analysis that the fan did not need to have Ex protection. As hydrogen is lighter than air, additional ventilation bricks were fitted in the roof area. So that the bottle racks could easily be loaded, a 2 wing door was fitted.

Result and customer benefits:

For the completion of this challenging project, DENIOS could draw on many years of experience as a developer and manufacturer of walk-in fire-rated storage containers. With access to all the right skills, DENIOS was able to develop a technical / safety room in a short time, which met all the requirements for F90 fire protection, fire alarm sensor technology, explosion protection and ventilation technology.
