Grid-based energy storage directly addresses one of the main issues facing renewable energy; renewable sources aren’t always available. The sun doesn’t always shine. The wind doesn’t always blow.

Energy storage solutions allow energy to be stored during sunny and windy periods, and be released when it is needed. It may sound like a simple concept, but there are a number of ways energy storage can be achieved.

Energy Storage News – As researchers look for better ways to store energy, pseudocapacitors (“super-fast batteries”) have proven to be of great interest thanks to their fast charging and discharging, high power density, and excellent cycling stability. The technology is likely to be beneficial to many potential applications ranging from personal (think portable electronics) to nationwide grid energy storage. Typically, transition metal oxides are used in electrodes of batteries and these pseudocapacitors.

The U.S. energy storage market is continuing along a roller-coaster of rapid growth, according to the latest report by GTM Research and the Energy Storage Association (ESA). Q1 2016 U.S. Energy Storage Monitor found a 127% growth year-over-year to 18.3 MW installed, which is also down 84% from a spike in the fourth quarter of 2015.

The market is also changing significantly. While behind-the-meter installations have in the past been a much smaller market than utility-scale, during Q1 behind-the-meter energy storage made up nearly half of all newly installed capacity at 8.9 MW. This is accompanied by an ongoing geographic shift in the market.

Energy Storage News – According to GTM Research and ESA’s latest U.S. Energy Storage Monitor, the U.S. deployed 18.3MW (21.2MW-hrs) of energy storage in the first quarter of 2016. Deployments were up 127% year-over-year, but down 84% from the historic fourth quarter of 2015.

The first quarter continued the trend of relatively slow starts seen over the last few years. However, residential energy storage was a standout segment both quarterly and annually. More than 8.9MW were deployed in behind-the-meter applications.

Energy Storage News – A new report titled “Closing the California Clean Energy Divide” has highlighted some key insights about the housing market in California as it relates to solar power and energy storage. California has done well in the installation of solar power systems, including some paired with energy storage technology. However, the affordable multifamily rental housing sector is currently not experiencing the same level of solar and energy storage installations.

Energy Storage News – Getting extra power to where it’s needed is a tricky business, often requiring millions of dollars in investments.

Now a solar-industry veteran has proposed a cheaper alternative: juice stored in batteries that are delivered by truck, rail or barge.

Shihab Kuran, who founded Petra Systems Inc. and also worked at NRG Energy Inc. and SunEdison Inc., has now formed Power Edison, which offers grid-scale lithium-ion battery systems encased in specialized shipping containers that can be stacked like Legos.

Government subsidies should be used to encourage investment in energy storage to fully integrate renewables in the sector.

That’s according to a study by the University of East Anglia (UEA), which insists investment in power storage is vital for renewables to achieve their full potential.

The study focused on two types of storage systems – pumped hydro storage and compressed air energy storage.

Energy Storage News – Numerous reports claim that, if the world is going to transition to a low-carbon economy to meet internationally set global warming targets, large-scale energy storage technology will be essential due to the intermittent nature of renewable energy resources.

However, low-cost power storage capabilities still evade the energy industry and, at present, there appears to be little appetite to invest in this disruptive technology.
