    JIMIQ: To je optimisticke. Ted jeste jak to dostat na ty udrzitelne mene jak 5 MLD.
    BTW - Ja zas dost slychavam neco kolem 2100 / 11 MLD.

    zajmavej clanek. bejvalej exec Blackrocku o klimatu, trhu a zelenejch investicich. ve zkratce rika, ze bez carbon tax to nepujde/nikam nepovede. nevim jak moc s tim souhlasit, protoze zanedbava fakt, ze na renewables se da vydelat a bude lip, v sirsim kontextu ale bude mit pravdu

    blackrock na to reaguje, ze to tak neni (zmenili strategii z fosil na green investments, musi to hajit) a zaroven dodava, ze opravdu statni regulace by pomohly vic/rychleji nez freemarket, takze s nim vlastne souhlasi :)

    $5.4 B Project Will be World's Largest Green Hydrogen Producer in 2025
    https://cleantechnica.com/...lion-project-aims-to-be-worlds-largest-green-hydrogen-producer-in-2025/

    Enegix Energy is moving forward with plans to build a $5.4 billion facility off the coast of Brazil called Base One. And that’s news because the company claims that Base One will be the world’s biggest individual CO2 reducer by generating more than 600 million kg of green hydrogen per year by the time it’s fully operational in 2025.

    Australian scientists achieve breakthrough with renewably powered carbon capture – pv magazine International
    https://www.pv-magazine.com/...-scientists-remarkable-renewably-powered-carbon-capture-breakthrough/

    Australian scientists have achieved a new breakthrough in carbon capture and storage. Their novel electrochemical process can store carbon dioxide in water with the power of solar or wind, while also producing by-products such as green hydrogen and calcium carbonate – perhaps the key to decarbonizing the cement industry.

    Researchers from the Queensland University of Technology have made a remarkable breakthrough with the development of an electrochemical process in which carbon dioxide is captured from the air and stored in water as a non-toxic calcium carbonate (chalk) in a renewably powered process that could also produce green hydrogen and decarbonize the cement industry. 

    ...

    We found we could use seawater once it had been treated to remove sulphates. To do this we first precipitated calcium sulphate or gypsum, another building material, and then carried out the same process to successfully turn CO2 into calcium carbonate, thus providing proof of concept of a circular carbon economy,” O’Mullane said. “Next, the hydrogen evolution reaction during electrolysis ensured that the electrode was continually renewed to keep the electrochemical reaction going while also generating another valuable product, green hydrogen. This means if this electrolysis process is powered by renewable electricity, we are producing green hydrogen alongside the calcium carbonate (CaCO3).”

    Farming fish in fresh water is more affordable and sustainable than in the ocean
    https://phys.org/news/2021-03-farming-fish-fresh-sustainable-ocean.html

    Optimistic projections say that smart mariculture—fish farming at sea—could increase ocean fish and shellfish production by 21 million to 44 million metric tons by 2050, a 36%-74% jump from current yields. Other estimates suggest that an ocean aquaculture area the size of Lake Michigan might produce the same amount of seafood as all of the world's wild-caught fisheries combined.

    The Environmental Protection Agency (EPA) is underestimating methane emissions from oil and gas production in its annual Inventory of U.S. Greenhouse Gas Emissions and Sinks, according to new research from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS). The research team found 90 percent higher emissions from oil production and 50 percent higher emissions for natural gas production than EPA estimated in its latest inventory.

    Volcano in Iceland Is One of the Largest Sources of Volcanic CO2

    The Soil Carbon Sink Doesn’t Grow With Atmospheric CO2, Study Finds
    https://cleantechnica.com/...3/26/the-soil-carbon-sink-doesnt-grow-with-atmospheric-co2-study-finds/

    Soil’s capacity to store carbon may be less than previously thought, according to a study published in Nature.

    The amount of carbon stored in soil is approximately triple that stored in living plants, but as rising CO2 levels increase plant growth, the scientists found, soil carbon storage decreases.

    We expected faster plant growth and more biomass to increase soil organic carbon, as extra leaves and biomass fall to the forest floor [but] it didn’t,” Stanford professor and senior author Rob Jackson told Earther.

    The findings, the scientists say, mean global heating could accelerate more quickly than previously expected. “If we really want to stop global warming,” César Terrer, who led the research while at Stanford University, told The Guardian, “we need to stop emissions, because ecosystems only take up a fraction of all the CO2 emissions.”
