The way the world gets its electricity is undergoing a rapid transition, driven by both the increased urgency of decarbonizing energy systems and the plummeting costs of wind and solar technology. In the past decade electricity generated by renewables in the U.S. has doubled, primarily from wind and solar Tiếp tục đọc “Utility-Scale Energy Storage Will Enable a Renewable Grid”

Could water solve the renewable energy storage challenge?

Seasonal pumped hydropower storage (SPHS), an already established yet infrequently used technology, could be an affordable and sustainable solution to store energy and water on an annual scale, according to new IIASA research published in the journal Nature Communications. Compared with other mature storage solutions, such as natural gas, the study shows that there is considerable potential for SPHS to provide highly competitive energy storage costs.

An oft-repeated refrain—the sun doesn’t always shine, and the wind doesn’t always blow—is sometimes seen as an impediment to renewable energy. But it’s also an impetus toward discovering the best ways to store that energy until it’s needed.

Declining costs in available technologies have propelled interest in energy storage forward like never before. The price of lithium-ion batteries has fallen by about 80% over the past five years, enabling the integration of storage into solar power systems. Today, nearly 18% of all electricity produced in the United States comes from renewable energy sources, such as hydropower and wind—a figure that is forecast to climb. And as communities and entire states push toward higher percentages of power from renewables, there’s no doubt storage will play an important role.

Compared with the same period a year earlier, the United States saw a 93% increase in the amount of storage deployed in the third quarter of 2019. By 2024, that number is expected to top 5.4 gigawatts, according to a forecast by market research firm Wood Mackenzie Power & Renewables. The market value is forecast to increase from $720 million today to $5.1 billion in 2024. Driving such growth is an increased focus on adding renewable energy sources to the nation’s grid.

Top 5 Developments Enabling Shift to 100 Percent Renewable Energy

Renewableenergyworld – A growing number of companies, cities, states and countries are aiming for, and achieving, a goal of obtaining power from 50 percent, 75 percent or even 100 percent renewable energy, thanks, in part, to a set of major developments that are enabling the resource shift, according to a new report from Clean Edge.

Commissioned by SolarCity, the report Getting to 100 discusses what is driving the transition to increasing levels of renewable energy consumption and identifies the successes and challenges of both governments and companies in targeting, and/or achieving, 100 percent renewable energy goals.

According to the report, these five developments are supporting the trend toward higher penetrations of renewable energy:

  • A resilient grid
  • A rise in net zero buildings and smart connected devices
  • Energy storage availability and affordability
  • Proliferation of utility-scale renewables
  • Cost-effective status of distributed solar across geographies

Distributed Solar Becomes Cost-Effective Across Geographies

The proliferation of ever-cheaper distributed solar generation – residential, commercial and community – is a key driver toward the 100 percent renewable energy goal, according to the report.

“The cost curves are undeniable,” the report said. “The plummeting prices of solar panels have been well-documented, but the industry has recently been attacking balance-of-system costs and so-called soft costs (such as marketing, customer acquisition, permitting, and installation) as well.” Tiếp tục đọc “Top 5 Developments Enabling Shift to 100 Percent Renewable Energy”
