The battery-storage market is expected to grow fast in the next decade, with Tesla Inc. and Siemens AG among other new entrants

General Electric is set to announce GE Reservoir, a giant new battery platform for storing power generated by wind turbines and solar panels. Shown, an engineer climbing out of a GE turbine at a wind farm in Mongolia in 2016.

HOUSTON— General Electric Co. plans to unveil a new battery platform Wednesday as it seeks to become a leader in the emerging market of storing electricity.

The giant platform called GE Reservoir will be able to store power generated by wind turbines and solar panels for later use. It will also be able to be used to add jolts of power when needed to stabilize voltage and frequency on the electric grid. Den Rest des Beitrags lesen »

Google parent developed plans to store electricity from solar panels or wind turbines as thermal energy in hot salt and cold liquids, such as antifreeze

X engineers work on designs for an energy system that stores electricity as thermal energy in high-temperature molten salt and a low-temperature liquid. X is a “moonshot” research and development lab under Google’s parent, Alphabet.

Google parent Alphabet Inc. is pitching an idea to store power from renewable energy in tanks of molten salt and cold liquid, an example of the tech giant trying to marry its far-reaching ambitions with business demand.

Alphabet’s research lab, dubbed X, said Monday that it has developed plans to store electricity generated from solar panels or wind turbines as thermal energy in hot salt and cold liquids, such as antifreeze. The lab is seeking partners in the energy industry, including power-plant developers and utilities, to build a prototype to plug into the electrical grid. Den Rest des Beitrags lesen »

Home Energy Storage Enters a New Era

Advanced lithium-ion chemistries offer cooler operation, longer life spans.

WHY IT MATTERS: Cheaper energy storage is needed to integrate renewable energy sources into the grid.

SimpliPhi’s installations, like this one for the Los Angeles Department of Water and Power, can help reduce loads on the grid and integrate more power from renewable sources.

Driven by the explosion of residential solar power, the market for home energy storage—which attracted little interest until earlier this year, when Tesla announced its Powerwall battery—is suddenly looking crowded.

This week at the Solar Power International show, in Anaheim, a company called SimpliPhi Power is unveiling a lightweight battery system for homes and small businesses that offers a longer life span than other lithium-ion batteries and doesn’t require expensive cooling and ventilation systems.

Solar is giving hundreds of millions of Africans access to electricity for the first time

Subject: Africa: A brightening continent

Solar panelsFOR THE WORLD’S 1.2 billion poorest people, who are facing a long and perhaps endless wait for a connection to mains electricity, solar power could be the answer to their prayers. A further 2.5 billion are “underelectrified”, in development parlance: although connected to the grid, they can get only unreliable, scanty power. That blights lives too. The whole of sub-Saharan Africa, with a population of 910m, consumes only 145 terawatt hours of electricity a year—less than the 4.8m people who live in the state of Alabama. That is the pitiful equivalent of one incandescent light bulb per person for three hours a day.

In the absence of electricity, the usual fallback is paraffin (kerosene). Lighting and cooking with that costs poor people the world over $23 billion a year, of which $10 billion is spent in Africa. Poor households are buying lighting at the equivalent of $100 per kilowatt hour, more than a hundred times the amount people in rich countries pay. And kerosene is not just expensive; it is dangerous. Stoves and lamps catch fire, maiming and killing. Indoor fumes cause 600,000 preventable deaths a year in Africa alone. But candles or open fires are even worse—and so is darkness, which hurts productivity and encourages crime. Den Rest des Beitrags lesen »
