Energy storage systems are already being sold around the world to utilities and to homeowners with rooftop solar. However, studies suggest that long-duration energy storage on the scale of days or even weeks, will be necessary to address the seasonal variation of expanded renewable generation. On February 24, OurEnergyPolicy held a webinar examining this issue and featured a panel of experts discussing the potential industry impact of various energy storage technologies, as well as relevant policies.

A Grand Challenge to Commercialize Energy Storage

Author(s): Faith Martinez Smith

Date: March 5, 2020 at 10:12 AM

Note: At the time of this discussion, Faith Martinez Smith was a Policy Analyst at ClearPath, managing the organization’s energy storage, geothermal, and hydropower portfolios.   Grid-scale energy storage is critical for decarbonizing our economy and merits high-profile attention from our policymakers. Storage is technology agnostic—it can be used with any generation technology, provides ancillary services, and can reduce demand charges. As climate change policy continues to take center stage, the commercialization of U.S. energy storage technologies can play a pivotal role in enabling higher integration of variable renewable resources (wind and solar power) and addressing grid reliability. Thus far,… [more]

Energy storage, a potential solution for integrating intermittent renewables and improving grid stability, again saw rapid growth this past year. A “transition year” for U.S. energy storage, 2016 saw a more diverse market emerge “both in terms of the types of systems (market segments) deployed and the business models.” These trends are expected to continue in the U.S. with combined residential, commercial, and industrial energy storage deployments predicted to surpass 2 GW by 2021. Despite this rapid growth, there are those who claim that the adoption of storage has been slowed by a “web” of regulations at all levels. Some… [more]

Do We Have The Raw Materials For The World To Become 80% Renewable By 2050?

There have been many voices lately saying that renewables could produce 80% or more of the world’s energy by 2050 in order to limit global warming to 2.5°C, as long as we develop sufficient energy storage and bring up efficiency and conservation. But the real issue is raw materials. It takes about 500 tons of steel and 1000 tons of concrete per MW of wind power. Even more to connect them to the grid. The United States has used 40 million tons of steel to build 48,800 wind turbines totaling 74,512 MW and costing about 150 billion dollars. Wind energy… [more]

The Energy Storage Promotion and Deployment Act of 2015, recently introduced by Sen. Marin Heinrich (D-NM) and Sen. Angus King (I-ME), seeks to create a National Energy Storage Standard. Similar to a Renewable Portfolio Standard, the storage standard would require electric utilities to meet a percentage of their generation via storage, in this case 1% of peak demand using any energy storage technology by 2021 and 2 percent by 2025. In real terms, utilities would have to add 8 GW of storage by 2021 and 18 GW by 2025. Available technologies range from electric and thermal salt batteries to pumped… [more]

The State And Promise Of Energy Storage

Author(s): Ken Dragoon
Executive Director
Renewable Hydrogen Alliance
Date: October 6, 2014 at 10:00 AM

Energy storage has become one of the hottest topics in the electric power industry today as penetration levels of variable energy resources (e.g. wind, solar) rise rapidly. However, from the perspective of the electricity industry, analyzing energy storage can be dauntingly complex, and financial incentives are weakened by depressed electricity prices. A recent study summarizing the state of energy storage, “Energy Storage and Opportunities: A West Coast Perspective White Paper,” offers the following conclusions: Complexities in calculating and realizing the value of energy storage provides multiple system benefits that are often not fully valued, partly because of the complexity involved.… [more]

Last month, the National Alliance for Advanced Technology Batteries released “Distributed Energy Storage: Serving National Interests,” a white paper which outlines the benefits of distributed energy storage (DES) and its relationship to the nascent electric vehicle (EV) industry. According to the paper, DES systems can increase grid reliability, stability and security because of their “ability to provide… electric supply capacity and energy time shift, ancillary services, transmission and distribution (T&D) system support, electric utility customer energy cost management, and renewable energy integration.” These advantages may be necessary if the U.S. were to increase integration of renewable energy sources, see a… [more]

On March 13th, C2ES held a panel discussion in Washington, DC titled “Electric Vehicles Plugging into the U.S. Grid.” The panel addressed the opportunities and challenges surrounding broad roll-out of plug-in electric vehicles (PEVs). A key point of discussion was the need for harmonization between the auto industry, utilities, and government so as to optimize the electric grid as PEVs become a larger proportion of the vehicle fleet. Another key point was the need for consumers that are well-educated on PEVs. What’s keeping PEVs, and other alternative fuel cars, from breaking into the market? Is it simply a lack of… [more]

As reported by the New York Times, Envia Systems, a California-based battery manufacturing company, announced yesterday what it calls a “major breakthrough” in battery technology that is “poised to revolutionize cost, range and safety in electric vehicles.” According to Envia’s press release, the breakthrough is a world record 400 Watt hour/kg lithium-ion battery, at a cost of $150 per kilowatt-hour, which is expected to “slash the price of a 300-mile range electric vehicle by cutting the cost of the battery pack by more than 50 percent.” Envia was awarded $4 million by DOE’s ARPA-E in 2009, and later received $7… [more]

The New York Times recently published an article outlining the role of energy storage in facilitating increased adoption of renewable energy. The article highlights two companies – SolarReserve and BrightSource – that will open and operate solar thermal storage plants over the next several years. These plants will use the daytime sun to heat water and salt. The latent heat will then be used to power traditional electric turbines after the sun has set. The Energy Storage Council lists the following among the uses of energy storage: Enabling “renewables, solar or wind, to store energy generated during off-peak hours for… [more]
