According to Montena, during the next years the costs of double-layer capacitors will decrease significantly. Several reasons are given:

• First, the nominal voltage of Montena BOOSTCAPs®, currently rated at 2.5 V, will go up to 3 V within the next years. This way, the costs of a module built up from several capacitors units will be reduced by about 25 %.
• Second, an important cost reduction will come from the automation of the whole production process. Especially, the winding technology used for the production of double-layer capacitors offers a big potential for cost reduction.
• Third, cf. Scale effects .

Montena estimates that, thanks to these improvements, future costs per energy content will come down to 10 US$ per 1000 F. In addition, module costs will decrease due to higher production volumes and new low-cost voltage sharing technologies.
