Xcel energy wants to deliver carbon-free electricity by 2050. can capturing power plant emissions help it get there victaulic t gasket

Carbon capture is essentially the process of removing carbon dioxide, the primary contributor to global warming, from power plant exhaust and sequestering it into underground formations. electricity pick up lines The federal government has spent more than $7 billion on research into the technology, and a handful of projects are operating in the U.S., mostly piping carbon dioxide to inject into oil fields to improve production.

Xcel last year announced plans to close two aging coal plants, Comanche 1 and 2 near Pueblo, no later than by late 2025. Those two plants, built in the 1970s, together have a generating capacity of 660 megawatts — enough to power roughly a half-million homes. A third unit, Comanche 3, is one of the nation’s newest coal plants with a generating capacity of 750 megawatts.

Alice Jackson, the chief executive of Xcel subsidiary Public Service Co. of Colorado, stressed the company’s ambitions to have partnerships and collaborations. electricity cost per kwh south africa She did not identify specifically what partnership Xcel hopes to forge, but the speakers who were chosen for the announcement, held at the Denver Museum of Nature and Science, may offer some clues.

First came Colorado Gov.-elect Jared Polis, who ran on a platform of 100 percent renewables by 2040, and then Denver Mayor Michael Hancock, whose city has embraced an 80 percent goal. wd gaster cosplay tutorial Also speaking was Rich Powell, the executive director of ClearPath, a Washington D.C.-based organization that advocates for “developing and advancing conservative policies that accelerate clean energy innovation.”

But Leslie Glustrom, a biochemist and founding member of Clean Energy Action and long an adversary of Xcel in proceedings before the Public Utilities Commission, urged her followers to be “very, very wary of the ‘carbon capture’ research and design part of Xcel’s proposal. It’s not likely to work at any price or scale that matters. electricity outage houston The laws of chemistry and physics make that clear.” ‘We stand on their shoulders’

“The question that anyone with a fossil fuel plant has to ask is what are the comparative economics of the CCS versus all the other ways you might be able to reduce greenhouse gas emissions. That is a calculation that all of us who own fossil fuel plants have to do. gas jeans usa The other alternative is to close those fossil assets prematurely, before their useful lives have ended.”

Holy Cross in September announced a goal of 70 percent renewables by 2030 and comparable greenhouse gas reductions goals. It gets a substantial amount of its electricity from Xcel. As such, he said Xcel’s goal will allow Holy Cross to elevate its own goals. “We stand on their shoulders and if the shoulders get higher, we can reach higher ourselves,” said Hannegan.

“Self-styled climate advocates will ask utilities what they can do to create programs and policies in support of renewable energy and other goals,” he said. “I would encourage them to think more holistically about the energy system. A key challenge will be moving decarbonization to other parts of the economy, including transportation and buildings.”

Others will question why there needs to be government involved when Xcel and other utilities are making major advanced on their own. But government, he believes, needs to play a role in development of new technology. Energy solutions, he said, must transcend typical divides or rural vs. urban, liberal and conservative, and other divisions that now cleave the nation.
