The U.S. Department of Energy has invested over a billion dollars into mostly failed carbon capture programs since 2009

2021-12-31T11:08:00-05:00

The Biden administration wants to shove more money into projects that are supposed to capture CO2 emissions from power plants and industrial facilities before they can escape and heat up the planet. But carbon capture technologies that the Department of Energy has already supported in the name of tackling climate change have mostly fallen flat, according to a recent report by the watchdog Government Accountability Office.

According to the report, the Department of Energy (DOE) has invested about $1.1 billion in 11 carbon capture and storage (CCS) demonstration projects since 2009. Of those, only three were ever built, however, the sole participating coal plant shut down in 2020, leaving only two industrial projects in operation.

The U.S. Government Accountability Office (GAO) suggests that Congress consider implementing a mechanism for greater oversight and accountability of DOE CCS demonstration project funding. GAO also recommends that the DOE improve its project selection and negotiation processes and that they should establish more consistent scopes, schedules, and budgets for projects.

Los Angeles approves nation's largest solar and battery energy storage system

2019-09-12T17:37:00-04:00

Under the 25-year deal with developer 8minute Solar Energy, the city would buy electricity from a sprawling complex of solar panels and lithium-ion batteries in the Mojave Desert of eastern Kern County, about two hours north of Los Angeles. The Eland project would meet 6% to 7% of L.A.'s annual electricity needs and would be capable of pumping clean energy into the grid for four hours each night. The combined solar power and energy storage is priced at 3.3 cents per kilowatt-hour [...]

Los Angeles Mayor Eric Garcetti praised the approved Eland Solar and Storage Center as an integral part of the city's climate commitment to reach 55% renewable energy by 2025, 80% renewable energy by 2036, and 100% renewable energy by 2045.

"Located on 2,650 acres in Kern County, California, the project will include two large-scale solar facilities that will capture 400 megawatts (MW) of solar energy and store up to 1,200 megawatt-hours (MWh) of energy — all of which can be distributed to meet peak demand, reducing the need for natural gas at night or on cloudy days," explains a statement issued by the Mayor's office and the Los Angeles Department of Water and Power, adding, "The site will hold enough energy to power 283,330 homes across Los Angeles."

Are underground salt caves the next innovation in renewable energy generation?

2019-08-12T08:00:00-04:00

Compressed air energy storage has been used for decades, but only at two facilities in Germany and Alabama, built before solar and wind started creating challenges for power grid operators. “This is a pretty simple concept,” said Bobby Bailie, director of business development for energy storage at the German industrial firm Siemens. “You’re pushing air into a cavern, storing that energy. And at times when you need it, you pull it back out.”

Can a giant underground salt cave in the Utah desert hold a potential answer to Los Angeles’s growing sustainable energy needs?

The Los Angeles Times digs into a new-old approach for storing energy in compressed air deposits deep underground. The compressed air, generated with the help of solar or wind energy, is held deep below the surface of the earth until needed, creating a giant, high-pressure battery.

When the energy is required, say on a cloudy day when solar generation might dip, the compressed air is used to turn a second set of turbines that recaptures the air’s energy, thus converting the air into electricity.

Power companies take the pledge to deliver carbon-free electricity — one fossil-fueled plant at a time

2019-08-02T14:02:00-04:00

New Jersey's largest and oldest power company is pledging to deliver carbon-free electricity to fight climate change. To get there, the power company is shutting down its coal plants, betting big on offshore wind and working hard to keep its existing nuclear plant alive. PSEG said it won't build or acquire any new fossil-fueled power plants, including those running on dirt-cheap natural gas.

Announced in July, one of the oldest power companies in the U.S. is taking the next step towards addressing their involvement in battling climate change. The New Jersey power company PSEG has used fossil fuels to power their plants for the last 116 years. As the oldest power company in America, their initiatives to make changes addressing their plants' carbon emissions is a big step.

According to CNN, "To get there, the power company is shutting down its coal plants, betting big on offshore wind and working hard to keep its existing nuclear plant alive. PSEG said it won't build or acquire any new fossil-fueled power plants, including those running on dirt-cheap natural gas."

PSEG is not the only company to address these issues on climate change. Companies like Xcel Energy, formerly a coal-first company, is making moves to provide zero-carbon electricity by the year 2050. Although the Trump administration has made efforts to save the coal industry by promoting fossil fuels and cutti...

What will become of retired coal-fired power plants? A new "playbook" outlines a plan

2019-07-05T18:35:00-04:00

Nearly 300 coal-fired power plants have been "retired" since 2010, according to the Sierra Club. It's a trend that continues despite President Trump's support for coal. That has left many communities worried that those now-idled places will simply be mothballed.

In an NPR segment, which aired in May, Jeff Brady discusses the Department of Community and Economic Development's plans to reuse and redevelop retired coal plants. Plans of action are listed in a "playbook" that outlines the attributes of listed coal plants and the pros and cons of each site. Through these assessments, it will help the Department realize what types of business would be an appropriate fit to relocate there. With the increased number of coal plants shutting down opportunities for coal cities will change for the better thanks to plans of introducing new businesses to the area by promoting these unused sites.

Examples of the playbook in action are happening now in the small Pennsylvania town of Shamokin Dam. The coal-fired plant in town provided power for over six-decades before it was shut down in 2014. However, with the Department's new plans for redevelopment, the once forgotten site is teeming with activity. In the segment Brady shares, "Environmental groups cheer...

Renewable energy production overtakes coal nationwide

2019-06-26T11:33:00-04:00

America's coal industry has already been left in the dust by natural gas. Now it's under immense pressure from the renewable energy boom. The renewable energy sector had slightly more installed capacity than coal in April, according to a Federal Energy Regulatory Commission report.

Surging renewable energy production capabilities have finally overtopped coal-fired power production in the United States in recent months, a historic first. The milestone is the latest development in a decade-long slide for coal-fired energy production, which peaked in 2008.

CNN reports that coal consumption has fallen 39% since then, while energy generated from solar, wind, and other renewable sources has climbed ever higher. Energy production capabilities from renewable sources now slightly exceed those of coal, a discrepancy that is expected to continue to climb. No new coal-fired power plants were put online last year, for example, while renewable energy potentials soared during the same period. Despite the shift, renewable energy production is not expected to overtake coal-generated power production on an annual basis for a few years.

The writing is on the wall, though. Jeff McDermott, a managing partner at clean energy investment bank Greentech Capital Advisors, told CNN, "C...

China plans to build a fleet of floating nuclear power plants

2016-04-25T15:15:00-04:00

All the radar systems, lighthouses, barracks, ports and airfields that China has set up on its newly built island chain in the South China Sea require tremendous amounts of electricity, which is hard to come by in a place hundreds of miles from the country’s power grid. Beijing may have come up with a solution: floating nuclear power plants. A state-owned company, China Shipbuilding Industry Corporation, is planning to build a fleet of the vessels to provide electricity to remote locations [...]
