Google’s newest pledge to help a brand new clear power know-how is… a gasoline mission? To be exact, it’s a gas-fired energy plant outfitted with filtering units to seize its planet-heating carbon emissions. Is that this only a polluting fossil gas mission in sheep’s clothes?
Google simply inked an settlement to help the event of a brand new gas-fired energy plant in Illinois referred to as the Broadwing Vitality Middle. It’ll be paired with carbon seize and storage (CCS), know-how meant to filter carbon dioxide from smokestack emissions after which retailer it underground in order that the greenhouse gasoline doesn’t construct up within the environment.
Is that this only a polluting fossil gas mission in sheep’s clothes?
In principle, that’s supposed to assist the planet from heating past the purpose at which rising sea ranges render whole coastal communities unlivable and ocean warming kills off the world’s coral reefs, amongst different disasters introduced on by local weather change. In actuality, CCS is mired in doubts about its technical and monetary feasibility. There’s additionally a wholesome quantity of skepticism over whether or not CCS will solely extend dependence on fossil fuels slightly than encouraging a transition to extra sustainable sources of power, like photo voltaic and wind energy.
Google says it has agreed to buy “most” of the facility that the brand new 400MW-capacity energy plant at Broadwing produces as soon as it begins working in 2030. “Our aim is to assist carry promising new CCS options to the market whereas studying and innovating shortly,” Google says in its announcement at this time.
To date, CCS has a reasonably checkered observe file within the US. The US Division of Vitality (DOE) has burned by way of lots of of hundreds of thousands of {dollars} on failed CCS initiatives, based on a 2021 report by the Authorities Accountability Workplace. Of almost $684 million spent on CCS initiatives at six coal vegetation, solely one in every of them ever got here on-line. The opposite initiatives suffered from “elements affecting their financial viability,” the GAO report says.
The price of electrical energy from energy vegetation mixed with carbon seize is no less than 1.5 to 2 occasions costlier than that from photo voltaic, wind, or conventional coal and gasoline energy vegetation with out CCS, based on a 2023 report primarily based on services in Australia. Already, rising electrical energy demand from knowledge facilities have contributed to climbing utility payments within the US.
The only CCS mission that moved ahead within the US with DOE help got here on-line in 2017 earlier than shuttering for a number of years beginning in 2020, when the covid-19 pandemic despatched oil costs crashing. Why was it so delicate to grease costs when the plant burned coal? It provided captured CO2 to an “enhanced oil restoration” mission, a course of involving taking pictures the CO2 deep into the bottom to drive out hard-to-reach reserves, as a method of staying financially viable.
The mission that Google is backing differs in a pair key methods. The plant burns gasoline, which has turn into a less expensive technique to generate energy than than burning coal within the US. And the CO2 shall be sequestered a mile underground in a effectively close to the facility plant, slightly than bought as a product for enhanced oil restoration. Google claims Broadwing will have the ability to completely retailer about 90 % of the carbon dioxide emissions the plant generates, a determine increased than many different CCS initiatives have been in a position to obtain up to now.
That doesn’t account for different issues related to gas-fired energy vegetation. Though the business prefers the time period “pure gasoline,” they primarily burn methane, which is a greenhouse gasoline much more potent than carbon dioxide. Methane routinely leaks from oil and gasoline wells and pipelines, an issue that merely capturing CO2 at an influence plant fails to unravel. Gasoline vegetation additionally produce different air pollution that pose well being dangers to close by communities.
Photo voltaic and onshore wind power farms don’t include the identical local weather air pollution issues and are sometimes cheaper to deploy than fossil fuel-fired energy vegetation lately. Google has been one of many largest company purchasers of renewable power for years now, serving to wind and photo voltaic turn into the fastest-growing sources of latest electrical energy era.
Google doesn’t point out that in its announcement at this time, nevertheless, maybe reflecting the political tide turning towards renewables within the US below the Trump administration. Donald Trump has put in fossil gas executives to guide the Division of Vitality and different key posts in his administration whereas clawing again beforehand allotted federal funds for renewable power initiatives and issuing cease work orders to offshore wind farms below building.
Republicans are sunsetting tax incentives for photo voltaic and wind initiatives, however not for CCS, by the way. CCS has wanted the monetary help to assist it get off the bottom, and now it has one other backer in Google. Google is making an attempt to satiate energy-hungry knowledge facilities because it scales up its AI ambitions, and its carbon footprint has grown within the course of.
