Energy Storage

Although the “solar flow battery” is currently considered too expensive by its own creators, a further improvement of its design and the use of emerging solar materials and new electrochemistry may open new opportunities for this kind of technology.

DNV GL has issued its annual Energy Transition Outlook. It reports that global electricity demand is set to grow by a factor of 2.5. Over half of this demand is expected to be met with renewable energy by 2050, while storage will play a key role. It adds that grid infrastructure expenditures are less related to variable renewable energy assets than to increasing energy demand. In the current scenario, meanwhile, global warming is likely to reach 2.6°C.

The historic French brand says it will focus on rail, telecom and infrastructure, but environmentalists hoping the move finally heralds a breakthrough for electric vehicles in one of the world’s biggest transport markets appear set to be disappointed.

Following hot on the heels of Exide Industries, lead acid battery maker, Indian-based Amara Raja Batteries Limited has said it will set up a 100 MWh lithium ion assembly plant in Andhra Pradesh. The company aims to establish a foothold in the energy storage market for electric vehicles.

With a rapid reduction in costs, solar plus storage can be an effective alternative for customers buying peak power from the grid. At the same time, utilities can avoid investments in peak capacity or eliminate load shedding by utilizing these resources.

Hyderabad based Cygni Energy plans to utilize the capital to triple its solar DC solutions production capacity from 4,000 units to 12,000 by H1 2019, develop new technology-enabled products and streamline the product lifecycle, as well as expand nationally and internationally.

The Solar Energy Corporation of India Limited (SECI) has announced a tender for a 160 MW wind, solar and storage plant to be located in the state of Andhra Pradesh.

In the latest amendment to India’s National Wind-Solar Hybrid Policy, the word “battery” has been removed from a number of clauses, while the scope of storage has been broadened to include all technologies, like pumped hydro, compressed air and flywheel.

The U.S. Trade and Development Agency (USTDA) has approved a grant supporting the technical design and project planning work for IL&FS Energy Development Company Limited’s (IEDCL) 41 MW hybrid wind, solar and energy storage power plant in Andhra Pradesh.

India’s energy storage industry feels the government’s move to reduce GST on lithium-ion (Li-ion) batteries from 28% to 18% will benefit electric vehicles and the renewables sector. The government has also cut GST on the raw materials for battery manufacturing, to jump-start domestic industry.
