   As the global energy market, piece by piece, slowly but surely, moves towards a renewables-centered paradigm, dispatchable solar and uncurtailed wind, along with other forms of clean energy, are requiring longer and longer durations of storage to integrate them to the grid. While there’ll be a place for lithium-ion for many years yet, the technology really excels at applications of up to around four hours. For everything else, there’s a growing list of contenders, with diverse technologies and at different stages of commercialization. Here’s a handy guide to some of those technologies and their providers, electrochemical and otherwise, that promise anything from five hours to even days or weeks of storage.

   Recent growth in renewable energy, spurred by state mandates, federal tax incentives, and increasingly attractive costs, has shifted attention to the use of energy storage to ensure that variable wind and solar generation reliably serve load and provide ancillary services. In this domain, lithium-ion currently dominates. But some analysts don't see it as economically-efficient enough at scale to fully support the amount of renewable energy expected to come onto the grid, and other options are on the rise, including rail-based gravity systems, hydrogen and flow batteries.

   The Commonwealth of Massachusetts is likely to fall short of its greenhouse gas emission goals if it cannot implement utility-scale storage, according to a new study. More than 70% of the state’s two pumped-hydro storage facilities — with a collective capacity of around 1,800 MW — is currently unutilized due to the lack of market incentives, according to researchers. The lack of utility-scale storage could mean that the state’s grid remains “dirty” even with a high penetration of renewables.

   Scientists from General Electric's Global Research Center in Niskayuna recently won a $1.25 million grant from the U.S. Department of Energy to study the viability of so-called pumped storage hydropower technology that essentially stores up power generated from solar and wind farms for use on the electric grid. The grant, which was awarded by the DOE's Water Power Technologies Office, will be shared by GE Research, GE Energy Consulting and GE Renewable Energy's hydro team.

6. Hot Dam: How Hydro Storage Will Allow Uruguay To Join The 100% Renewables Club

   In recent years, 50-60% of Uruguay’s power has been generated from the country’s four hydroelectric dams on the River Uruguay. Most of the remainder comes from renewable energy sources such as solar panels and wind turbines. That combination has turned the country into the world’s poster child for low-carbon energy. The one remaining sticking point is storage. Without it, renewables can only be used as they are generated. Hydro storage provides reliability and flexibility to a renewables-based grid by creating a huge, continuously rechargeable battery that is entirely powered by the elements.

   The Ludington pumped storage facility is essentially one of the world’s largest batteries. Consumers Energy gets its base load of energy from its coal and gas plants across the state. When the energy demands peak above that base load, they need places like the Ludington Pumped Storage Facility to pick up the slack. In just a matter of minutes, they can open up the gates, get the water flowing through the turbines and pick up that amount. When the demand is low, like at night, they will start pumping water back in to the reservoir, getting ready for that next call.

   The Los Angeles Department of Water and Power has turned two big lakes into a monster battery capable of storing enough energy to power tens of thousands of homes. It involves using the excess wind and solar power L.A.'s renewable energy sites produce during the day to pump water from Castaic Lake uphill 7.5 miles to Pyramid Lake. Then, late in the day, when the sun goes down and the city's energy demand spikes, the water gets run downhill through hydroelectric generators at Castaic Lake.

    Pumped storage accounts for over 94% of installed global energy storage capacity, rightfully deserving the accolade of being the world’s ‘water battery’. The existing 161,000MW of pumped storage capacity supports power grid stability, with the International Hydropower Association estimating that total storage is in the region of 9000GWh. A recent working paper has been produced to help stimulate timely discussion among policy makers and energy system stakeholders about the increasingly important role of pumped storage in the clean energy transition. The paper provides an assessment of the technology’s current status as well as tracing its historical roots.

    The U.S. Department of Energy announced selections for up to $7.5 million for innovations that reduce cost and maximize the value of new stream-reach hydropower development and pumped storage hydropower. Funded projects will develop new design concepts and associated modeling and analysis for standard modular hydropower and pumped storage, respectively. DOE supports technologies consistent with DOE's Advanced Energy Storage Initiative—which drives technology beyond cost reductions toward improved performance and enhanced provision of services to the grid. Selections were made across two topic areas, including scientific analyses that would illustrate how pumped storage hydropower can optimize the performance of the U.S. electric grid system to lower overall system costs.

    Thousands of megawatt-hours of electrical energy squirreled away into utility-scale energy storage plants to cover the spread between generated renewable energy and the lowest reliable operating limit during the 10 a.m. to 3 p.m. “duck curve” period of the day — does this sound like a glimpse into the far future of major utilities across the United States and the world? But the future has already arrived at the Carolina operating companies of Duke Energy. The Duke Energy Progress Company, serving customers primarily in the eastern half of North and South Carolina, managed a whopping 106 GWh of excess energy in 2017, largely generated from utility-scale solar in North Carolina, using pumped hydro energy storage.

    Crane-suspended concrete segments, patterned like an enormous stave silo, power a commercial scale-ready system based on what Swiss developer Energy Vault describes as “the principles that underpin traditional gravity-based pumped hydro plants.” Software operates an automated six-arm crane and orchestrates positioning of the concrete segments that provide the basis for efficient electricity storage and discharge. The use of low cost and environmentally-friendly concrete materials enables the system to achieve low cost per kilowatt-hour and high round trip efficiency while delivering a 30-40 year life without any degradation in storage capacity. Energy Vault figures that a properly configured system will be capable of reaching 100 percent of target power levels in 2.9 seconds.
