Renewable Power

The Grid of the 21st Century: Making Renewable Energy a Priority Renewable energy has the promise to become the energy power house of the 21st century, creating jobs and new industries, and bringing improvements in air and water quality, energy security, access to energy and community development. [...] 3 Agence France-Press, 2 • Pembina Institute – Storing Renewable Power The Grid of the 21st Century The Benefits of Power Storage While the primary benefit of power storage capacity is to enable the integration of more renewable power sources into the grid, storage systems also offer many other benefits that can be summarized as foll. [...] At the Second International Energy Storage Conference (IRES II)8 in 2007 and the Electricity Storage Association’s (ESA) Annual Meeting9 in 2008, several speakers spoke of the important role storage will play in the grid of the future, the numerous technologies that are near to commercial and cost-effective deployment10 and the fact that some storage technologies are already being used for mainstr. [...] 8 • Pembina Institute – Storing Renewable Power The Growing Power Storage Industry Full scale tests of many storage technologies are underway, including a multi-source facility at the Riso National Laboratory in Denmark where flow battery storage is used to store wind, solar and diesel generated power and to provide power to a load controlled office building.22 The cost of newer power storage opti. [...] Energy is stored in the rotor in proportion to its momentum (at the square of surface speed).61 The rotor slows down as the energy is released — a reversal of the charging process — and the motor driving the flywheel acts as a generator.
