GlidePath Acquires 149MW Texas Wind Portfolio with Storage Additions Planned

GlidePath Power Solutions has acquired eight wind projects in North Texas with a total capacity of 149MW. The portfolio, purchased from Exelon Generation, will be optimised by GlidePath while it plans how best to add energy storage on-site at each project. The projects are all north of Amarillo and sell into the Southwest Power Pool (SPP). According to GlidePath, they will be the first battery storage projects in the SPP.

North Sea Rocks Could Act as Large-Scale Underwater Renewable Energy Stores, Study Finds

Rocks at the bottom of the North Sea may provide the perfect storage location for renewable energy, according to a new study. Excess power could be stored in the form of compressed air inside porous formations on the seabed, providing a reservoir that can provide energy on demand. This pressurized air can be released to drive a turbine, generating a large amount of electricity. This would allow green energy to be stored in summer and released in winter, when demand is highest.

Grid-Scale Energy Storage Firm to Launch Two US Projects in 2019

As liquid air energy storage company Highview Power prepares to launch two US projects this year, an official said Thursday, the company has teamed up with engineering firm Citec to help scale its storage facilities from 50 MW/500 MWh to multiple GWh. Though Cavada could not discuss specific locations or customers, he said Highview is looking at the wind corridor that runs through the Midcontinent Independent System Operator’s territory, as well as California, Texas and New York.

Molten Metal Energy Storage For Future Maritime Propulsion

The comparatively short sailing distances encountered along navigable inland waterways, combined with stops at navigation locks, enhances the attractiveness of using battery propulsion technology. While the popular electrochemical batteries involve lithium technology and chemical acid technology, other competing batteries operate at elevated temperatures utilizing molten metal energy storage. 

Renewables, Energy Storage, & Managing The Utility Grid Of The Future

Things are changing fast in the world of electricity generation and distribution. As always, changes are to the advantage of some and the disadvantage of others. The sharp drop in the cost of renewable energy in the past few years is the primary engine driving the changes. The next revolution is bulk energy storage, the piece of the puzzle that will turn traditional ideas of how an electrical grid should operate completely upside down. Here’s a look at what is happening right now and what the utility grid of the future may look like.

Xcel Energy, United Power Among Utilities Using Batteries

For longtime proponents of renewable energy, figuring out how to keep the lights on when the wind doesn’t blow and the sun doesn’t shine has been a key challenge. Harnessing the excess energy from a turbine or solar panel to use later was the “holy grail” or “golden key,” as one Colorado utility executive calls it.

Renewable Snergy Storage and the Future of Smart Cities

‘Smart cities’ are no longer considered to be just a buzzword; they are a topic of constant conversation, and they’ve already come to fruition across the globe. From Singapore to San Francisco, organisations, government officials and city planners have made incredible efforts to support the development of intelligent communities.

Southern Research, NICE Team to Repurpose Used EV Batteries as Energy Storage Systems

Southern Research and the National Institute of Clean and Low-Carbon Energy (NICE) are collaborating on a project to transform retired electric vehicle batteries into energy storage systems for offices and factories. Under the partnership, the Birmingham, Alabama-based research organization will provide critical testing services to assist NICE to develop stationary power systems using very low cost, retired EV battery packs for the U.S. market.

Energy Storage Technology Helps Renew, Stabilize Electric Grid

The U.S. Energy Information Administration reported that 17 percent of all electricity produced in the United States in 2017 came from renewable energy sources, including solar, wind and hydroelectric dams. That percentage is expected to keep growing as communities seek ways to improve local air quality and reduce greenhouse gas emissions linked by EPA scientists to climate change. Unfortunately, renewable energy sources need proper weather conditions to generate power. And those periods of sunshine, wind or heavy wave action occur only intermittently between 4 p.m. and 9 p.m. when consumer demand for electricity peaks. That’s where energy storage technology comes in.
