Can a solar-wind system meet future energy demands?

Accelerating energy transition towards renewables is central to net-zero emissions. However, building a global power system dominated by solar and wind energy presents immense challenges. Here, we demonstrate the potential of a globally interconnected solar-wind system to meet future electricity demands.

Which energy storage projects have been approved by state regulators?

Energy Dome and Alliant Energy's 200MWh long-duration energy storage (LDES) project in Wisconsin, US, has been approved by state regulators. The Ministers of Energy and the Environment in Lithuania have approved an additional €37 million (US$43 million) for an energy storage capex grant scheme, while Trina Storage has secured orders in the country.

How does solar-wind generation affect the cost of a solar system?

High penetration of solar-wind generation is invariably associated with increased curtailments and system-wide costs, with pronounced marginal cost effects. For instance, the cost increase required to raise penetration from 78% to 80% is more than four times that of raising it from 72% to 75%.

What are the biggest solar and storage projects in the US?

One of the biggest solar and storage projects underway in the U.S. is Longroad Energy's Sun Streams Complex in Arizona, totaling 973 MW of solar and 600 MW/2.4 GWh of battery storage capacity. After the first two phases began operations in 2021 and 2024, the fourth and largest project is underway with 377 MW of solar and 300 MW/1.2 GWh of storage.

What happens if solar-wind generation exceeds net power demand?

When solar-wind generation within a grid exceeds its net power demand (i.e., total demand minus baseload), surplus power is first transferred to interconnected grids experiencing shortages, with the remaining surplus stored until capacity is reached. Any surplus beyond storage capacity is curtailed.

How much does a solar-wind power outage affect electricity supply?

Under the S-G scenario, the decline in solar-wind electricity supply caused by the complete outage of a single regional grid averages only 2.6% (ranging from 0.7% to 11.7%), compared to declines of 5.8%, 15.1%, and 26.4% under the S-C, S-A, and S-I scenarios, respectively (Fig. 4b).

Does industry need energy storage standards?

As cited in the DOE OE ES Program Plan, “Industry requires specifications of standards for characterizing the performance of energy storage under grid conditions and for modeling behavior. Discussions with industry professionals indicate a significant need for standards ” [1, p. 30].

What safety standards affect the design and installation of ESS?

As shown in Fig. 3, many safety C&S affect the design and installation of ESS. One of the key product standards that covers the full system is the UL9540 Standard for Safety: Energy Storage Systems and Equipment . Here, we discuss this standard in detail; some of the remaining challenges are discussed in the next section.

What is energy storage R&D?

Under this strategic driver, a portion of DOE-funded energy storage research and development (R&D) is directed to actively work with industry to fill energy storage Codes & Standards (C&S) gaps. A key aspect of developing energy storage C&S is access to leading battery scientists and their R&D insights.

Is energy storage a future power grid?

For the past decade, industry, utilities, regulators, and the U.S. Department of Energy (DOE) have viewed energy storage as an important element of future power grids, and that as technology matures and costs decline, adoption will increase.

Are new battery technologies a risk to energy storage systems?

While modern battery technologies, including lithium ion (Li-ion), increase the technical and economic viability of grid energy storage, they also present new or unknown risks to managing the safety of energy storage systems (ESS). This article focuses on the particular challenges presented by newer battery technologies.

What are ESS standards & technical specifications?

The standards and technical specifications discussed above provide utilities and end users unique resources to compare various ESS technologies on an equitable basis in terms of performance, environmental compliance, and safety. It is important to treat the ESS as a black box for a direct comparison independent of battery technology.

How can Lagos improve its energy supply & demand?

Commissioned by C40 Cities, Arup conducted an extensive study reviewing Lagos's current energy supply and demand, its projected future needs, and the potential of various renewable technologies. We recommended a suite of measures, including localised solar power generation, energy efficiency improvements, and battery storage solutions.

How much electricity does Lagos have?

Home to 18 million residents, Lagos has only 850-1,000 MW of installed capacity serving the national grid, which meets just 10% of the city's electricity demand. The remaining demand is being met by fossil-fuel generators, firewood, or individual renewable energy systems – such as solar panels and biofuel.

Could solar photovoltaics meet 66% of Lagos's energy demand?

Solar photovoltaics combined with battery storage could meet 66% of Lagos's projected 2050 energy demand without significant infrastructure upgrades. Commissioned by C40 Cities, Arup conducted an extensive study reviewing Lagos's current energy supply and demand, its projected future needs, and the potential of various renewable technologies.

How much energy will Lagos generate by 2050?

The study estimated a total local renewable energy generation potential of 25 GW by 2050 – primarily from solar power. Solar photovoltaics combined with battery storage could meet 66% of Lagos's projected 2050 energy demand without significant infrastructure upgrades.
