Battery storage systems target Europe

March 15, 2017 // By Nick Flaherty
Samsung SDI has launched two battery storage systems targetted at the Eurpean market

The high-capacity E2 and high-power P3 models, whose energy density is sharply increased.

E2 is a 9.1MWh ESS battery that substantially increases the number of cells integrated in the container by upgrading the module design and rack arrangement technology. The company designed a compact module by reducing its size from 42 litre to 35 litre, while configuring it to increase the number of integrated cells in the module by 10% from 20 in previous modules to 22 cells. The design uses a new rack arrangement that removes passages in the ESS container and improves the cooling with gates on both sides of the container. This is nearly twice the capacity of previous products.

The E2 model is aimed at the utility ESS market that requires large capacity for storing energy during low-demand hours and using it in high-demand hours.

In contrast the 78Ah P3 is aimed at providing peak power stabilisation for sub-stations. The power of the cells was increased by 15% without changing the size of 68Ah battery cells in previous models.

The common feature of E2 and P3 is that their energy density is improved by increasing capacity while retaining the size of previous ESS containers. This saves construction and facility management costs by reducing scale of ESS facilities. Eventually, this will lead to reduction in investment on the part of customers.

Navigant Research expects that the world ESS market will grow by around 50% to 4.3GWh in this year, and sharply increase by around 60% annually by 2020 to 14.8GWh. In its report on the world ESS market for 2015, B3, a market research institution, announced that Samsung SDI ranked first in the market by taking 18% of its share.
