Studies on How Energy Storage Systems Affect the Grid

Testing will determine the effects of residential energy storage systems on local power grids.

Queen's University and RoseWater Energy Group, a provider of next-generation energy storage products, are conducting a collaborative study to evaluate the impact of a widely-distributed energy storage system on an electrical grid.

"The development and implementation of safe and efficient distributed energy storage systems is a critical factor for the future of a reliable and sustainable energy grid," said David Strong, Professor in Design Engineering at Queen's University and research leader.

Together with local distribution companies (LDCs), Queen's University and RoseWater Energy are determining the benefits of applying advanced lead acid storage technologies to an electrical grid.

"We are at a true watershed moment that will only become evident in hindsight," said Mario Bottero, president of RoseWater Energy.

"We're confident the results of this study will demonstrate that the true solution for distributed energy is through a massive network of energy storage units spread throughout the grid--perhaps having one in every home--and not massive multi megawatt centers that further strain the network and create as any problems as they solve," Bottero said.

Pending the results of the study's initial phase, Queens University and the participating LDCs would work with RoseWater to create a product based around RoseWater's proprietary storage technology, including those found in RoseWater's Residential Energy Storage Hub, that would address the energy needs.

Built to provide a variety of solutions for energy needs, the Residential Energy Storage Hub serves as an uninterruptible power supply (UPS) for a home.

The system employs the Axion Power advanced lead carbon battery which ensures 5-20 times the cycle life of traditional lead acid batteries, is safe for home use (UL approved) and is over 99 percent recyclable.

"Compared to other battery chemistries, [the Axion Power battery] excels in the combination of safety, cycle life, cell balancing, ambient temperature adaptability and cost," Strong said.

The Hub conditions incoming utility and auxiliary power while providing flexibility to the customer using integrated renewable solar and turbine energy. The system acts as a surge protector and ensures that, regardless of source, the connected circuits will always have a steady energy supply. It also allow homeowners to participate in demand-response programs from their local utilities and go "off grid," enabling power independence.
