North Sea Rocks Could Act as Large-Scale Underwater Renewable Energy Stores, Study Finds

Rocks at the bottom of the North Sea may provide the perfect storage location for renewable energy, according to a new study. Excess power could be stored in the form of compressed air inside porous formations on the seabed, providing a reservoir that can provide energy on demand. This pressurized air can be released to drive a turbine, generating a large amount of electricity. This would allow green energy to be stored in summer and released in winter, when demand is highest.

Solar + Storage Half The Cost Of Gas Peaker Plants — 8MinuteEnergy

S&P Global reports the cost of solar with battery backup dropped precipitously in 2018. Several tenders for solar plus storage came in at under $30 per megawatt-hour last year. Stand alone prices for installed battery storage — based on a 20 megawatt-hour system with 4 hours of storage — dropped 40% from the previous year to $357 per kilowatt-hour and are expected to keep falling. Bloomberg New Energy Finance projects a further 52% reduction by 2030. Such tumbling prices have led Wood Mackenzie to forecast that as the market for solar plus storage matures, it could put more than 6,400 MW of new natural gas-fired peaking capacity in the US at risk by 2027.

Grid-Scale Energy Storage Firm to Launch Two US Projects in 2019

As liquid air energy storage company Highview Power prepares to launch two US projects this year, an official said Thursday, the company has teamed up with engineering firm Citec to help scale its storage facilities from 50 MW/500 MWh to multiple GWh. Though Cavada could not discuss specific locations or customers, he said Highview is looking at the wind corridor that runs through the Midcontinent Independent System Operator’s territory, as well as California, Texas and New York.

DOE: Energy Security, Investments are Top Priority

In his keynote speech at the 2018 Energy Investment Forum held at the Shangri-La at the Fort, Secretary Alfonso G. Cusi highlighted the importance of investments in the sector, adding that it was the Duterte’s administration top priority. “Ensuring reliable, sufficient and affordable electricity in the country entails close cooperation and collaboration with all our partners in the industry,” Sec. Cusi was quoted as saying in a Philippine Information agency report.

Energy Storage Technology Helps Renew, Stabilize Electric Grid

The U.S. Energy Information Administration reported that 17 percent of all electricity produced in the United States in 2017 came from renewable energy sources, including solar, wind and hydroelectric dams. That percentage is expected to keep growing as communities seek ways to improve local air quality and reduce greenhouse gas emissions linked by EPA scientists to climate change. Unfortunately, renewable energy sources need proper weather conditions to generate power. And those periods of sunshine, wind or heavy wave action occur only intermittently between 4 p.m. and 9 p.m. when consumer demand for electricity peaks. That’s where energy storage technology comes in.

Energy Storage to Play Key Role for California to Reach Target of 100% Zero-Emission Electricity by 2045

SACRAMENTO, Calif., Sept. 10, 2018 — The California Energy Storage Alliance (CESA) applauds the California State Legislature for passing landmark Senate Bill (SB) 100, making California the largest U.S. state to set such an aggressive zero-emission electricity target. Since 2010, California has procured 1,514 MW of new energy storage capacity to support the grid – by far the most of any state. SB 100 would mandate 100% zero-emission electricity by 2045, with 60% renewables to be achieved by 2030. The bill now awaits the signature of California Governor Jerry Brown, who could sign it into law this week at the Global Climate Action Summit in San Francisco. The bill will update SB 350, passed into law in 2015, that requires retail sellers and publicly owned utilities to procure 50% of their electricity from eligible renewable energy resources by 2030. California efforts to date have been so successful that state legislators believe more aggressive targets are achievable.

BTM storage is booming in Ontario – Utility Dive

Ontario’s Global Adjustment (GA) charge is creating a behind-the-meter energy storage boom. Energy storage developers are flocking to Ontario offering large industrial customers tools to cut their demand, which is directly linked to the level of GA charge they have to pay. Industrial customers have had to pay a majority of their electricity bills to the GA charge, which the Ontario government established in 2005.

Green Energy is Gold for California, US

I am a physicist, and an energy and sustainability science researcher, and I live in California because of its penchant for not just setting but actually achieving big goals and adopting bold visions others may consider too ambitious. What California proposes, we research, debate and then accomplish. In fact, we often exceed the goals skeptics have deemed unmeetable. This is why I believe that California should — and ultimately will — pass into law the “100 Percent Clean Energy Act” (Senate Bill 100), which would establish a bold goal of 100 percent clean, zero-carbon electricity by 2045.

CAISO Could Lose 28 Gas Plants and Keep the Lights on: UCS

California could retire 28 natural gas plants without impacting electricity reliability, the Union of Concern Scientists said in a report published Tuesday. In order to meet the California Public Utilities Commission’s (CPUC) target to reduce carbon to 42 million metric tons (MMT) by 2030 in the most economic way possible, the UCS model chose not to build any new gas plants to replace less efficient combined-cycle gas turbines.
