Węgiel dusi fotowoltaikę. Zanieczyszczenia z elektrowni fizycznie blokują produkcję energii ze słońca
Elektrownie węglowe nie tylko emitują gazy cieplarniane i toksyczne popioły, ale również w bezpośredni sposób uderzają w swoją największą rynkową konkurencję.
Najnowsze badania opublikowane na łamach „Nature Sustainability” pokazują, że aerozole powstające przy spalaniu paliw kopalnych zasnuwają niebo na tyle szczelnie, by zauważalnie obniżyć wydajność paneli fotowoltaicznych na całym świecie. Straty idą w setki terawatogodzin rocznie.
Cień wielkości 84 elektrowni
Do oszacowania skali zjawiska zespół brytyjskich naukowców wykorzystał globalny rejestr farm słonecznych, uzupełniony o zdjęcia satelitarne analizowane przez sztuczną inteligencję oraz lokalne dane pogodowe. Wyniki pokazały, że w 2023 roku światowa fotowoltaika straciła ponad jedną czwartą swojego potencjału produkcyjnego ze względu na ograniczony dostęp do światła. O ile 20 procent tych strat to naturalna zasługa chmur, o tyle kolejne 6 procent to bezpośredni efekt zawieszonych w powietrzu aerozoli.
W liczbach bezwzględnych to ponad 500 utraconych terawatogodzin (TWh) energii rocznie. Aby to zrekompensować, trzeba by zbudować 84 duże elektrownie węglowe (każda o mocy 1 GW), pracujące na pełnych obrotach przez cały rok. Co więcej, w latach poprzedzających 2023 rok, globalnie instalowano moce słoneczne zdolne wygenerować dodatkowe 250 TWh rocznie, z czego aż 75 TWh było natychmiast „zjadane” przez zanieczyszczone powietrze.
Geograficzny paradoks
Za niemal połowę badanych aerozoli odpowiada dwutlenek siarki, będący produktem ubocznym spalania węgla. Kolejne 18 procent to materiał bogaty w węgiel, również pochodzący w dużej mierze z paliw kopalnych.
Wpływ tego zjawiska jest silnie uzależniony od geografii. W Chinach zanieczyszczenia obniżyły produkcję energii słonecznej o 7,7 procent, niwelując od jednej trzeciej do połowy rocznego wzrostu wydajności tamtejszych farm. Jak zauważają badacze, mapa strat w produkcji fotowoltaicznej w Chinach idealnie pokrywa się z mapą lokalizacji elektrowni węglowych. Dla kontrastu, w Stanach Zjednoczonych straty wyniosły zaledwie 3 procent, ponieważ panele słoneczne montuje się głównie na słonecznym południu i zachodzie kraju, podczas gdy przemysł węglowy skupiony jest na wschodzie.
Dane te pokazują rzadko omawiany aspekt transformacji energetycznej. Węgiel okazuje się jedynym powszechnym źródłem energii, które w sposób fizyczny tłumi produktywność swojego bezpośredniego następcy. Oznacza to również, że zamykanie starych bloków węglowych przyniesie podwójną korzyść: nie tylko zmniejszy emisje, ale z automatu podniesie efektywność już istniejących farm słonecznych. Zainteresowanych pogłębieniem tematu odsyłam do źródła w Nature Sustainability.

I like this idea way more than floating #NuclearPlants...!
These remarkable floating #SolarPanels solve one of the biggest problems with sun-based energy — here’s how they work
Story by Rick Kazmer, October 20, 2023
"Solar power innovators in Europe, Asia, and North America are launching flotillas of solar panels on open water with shocking results.
"In this case, electricity and water are a great combination, sometimes providing new life for forgotten lagoons that were created for past industrial efforts. Bloomberg reported that an old coal pit can be turned into a 'green powerhouse' when covered with floating panel systems, and such a project has the potential to replace fossil-fuel generation entirely in certain communities.
"When operational, these systems could make towns self-sufficient energywise. A paper in the journal #NatureSustainability claims that more than 6,200 'communities and/or cities in 124 countries' could provide all the power needed with floating solar energy systems.
"Cohoes, New York, is an example of how these projects can work in America’s towns.
"Here, with no land available for a #SolarFarm, city planner Joe Seaman-Graves looked to an unused 14-acre reservoir in his town, according to a PBS report. A floating solar energy system is slated to be completed in Cohoes, which has a population of about 17,000, this year at a cost of about $6 million to $6.5 million. PBS reported that the federal government and other incentives are covering about half the cost.
"The price tag to get a floating system running is higher than other solar operations, and experts are studying aquatic ecosystems to ensure the projects don’t impact life under the water. Once completed, however, the returns can be great. The solar energy system in Cohoes could power the town’s government buildings and street lighting, realizing a $500,000 yearly savings, all per PBS."
