OGRON new energy storageA new dimension in application possibilities for lithium batteries promisses the company OGRON. First time are storage power plants mentioned as target market.
OGRON mentions cells with up to 8000 Ah. Until now, the largest cell known by me was the 240 Ah cell from Kokam. The photo shows a 200 Ah cell, the 240 Ah version is only correspondingly more thick What to do with an 8000 Ah cell? Let's start with a 42 tons truck. 6 tons with 160 Wh per kg makes 800 kWh batteries. But built with 8000 Ah cells, this would be only 100 Volt.( 800.000 Wh / 8000 Ah = 100 V ). This first thought shows, 8000 Ah cells are for much larger applications than for a 42 tons truck.
Storage power plants for electric power, large ships, only for this applications are 8000 Ah cells useable. Until now, we examined lithium batteries only regarding to electric mobility. Gasoline and Diesel vs electric power and lithium batteries had been the big compare. But here, we have to compare at a complete different level. Lithium batteries vs pump storage power plant. Lithium batteries vs Compressed air power plant. That are complete new dimensions. Our cars burn only the best part from crude oil. Because of environment requirements sulfur reduced Diesel. But big ships burn the last dirt of crude oil, the heavy oil. Even there are different sorts, The bigger ships can use lower qualities of heavy oil.
Because of the absence of prices on the Ogron web site, we have to combine "economical production technology" with our interrogations about the price development. We estimate for 2010 to 2012 a price at 300.-EUR per kWh capacity. |
