  1. Drinking water protections:

    By Ben Szalinski and Brenden Moore, Capital News Illinois

    “Illinois Senate Bill 1723 bans #carbon #sequestration — the process of capturing and storing carbon by injecting it underground — within an area that “overlies, underlies, or passes through” a U.S. Environmental Protection Agency-designated sole-source aquifer. #EPA

    The new law applies to the footprint of the #Mahomet #Aquifer, which is the main source of drinking water for more than 500,000 people across a 15-county area in central Illinois.

    It comes as Illinois, especially downstate, is targeted for carbon sequestration projects due to the state’s favorable geology and the availability of federal tax credits.

    Studies, including those conducted by researchers at the #universityofillinois have found minimal risk to water sources from sequestration activity.

    But the legislation was a priority for central Illinois community #activists #environmental advocates and a bipartisan cadre of local lawmakers with zero risk tolerance due to the lack of a clear alternative water source if the aquifer were tainted.”

  2. Call your damned Senators! Anyone claiming this reconciliation bill "doesn't touch Medicare" is using weasel words. Technically it is true the bill does not touch it directly, but they know it triggers #sequestration which leads to cuts in #Medicare and #SocialSecurity. #SocialSafetyNetCuts #BigHorribleBill

    Compost & Biochar Could Boost Carbon Sequestration by Crushed Rock
    Crushed rock additives may also help decrease soil emissions of other greenhouse gases, such as nitrous oxide & methane. eos.org/research-spotlights/co [science mag]

    Enhanced rock weathering (ERW) is a proposed method of CO2 #sequestration that spreads crushed silicate minerals on soils to drive chemical reactions that form carbonate minerals: Essentially, boosting the natural process of rock weathering, in which carbon is transferred from the atmosphere into rocks.

    Researchers spread finely crushed metabasaltic rocks across test plots in Browns Valley CA in each of 3 yrs. Along with crushed rock, some applications included compost or a combination of compost & #biochar. Other plots were treated with only compost, & a group of control plots received no treatment.

    Combining crushed rock, compost, & biochar yielded the best results; in addition to sequestering carbon, the mixture reduced NOx emissions & increased methane conversion, resulting in increased greenhouse gas mitigation overall. The researchers estimate that if the combination of all three materials were expanded to cover 8% of California’s total rangelands, it could sequester up to 51.7 million metric tons of CO2e per year.

    CA Ag Sector emissions are 32 million metric tons [including cow farts]. CA total emissions are 381 million metric tons. If 58% of rangeland were covered, we would become carbon neutral.

  4. How is the C balance of #plants and #ecosystems regulated: We assume that C #sequestration under future #climate conditions will follow #optimality principles that balance #water and #carbon resources to maximize growth in the long term nph.onlinelibrary.wiley.com/do

  5. Pennsylvania is at a crossroads: The resources that fueled Pennsylvania’s past growth are plateauing or petering out.

    “Coal employment has gone off a cliff,” said Seth Blumsack, who runs the Center for Energy Law and Policy at Penn State.

    “You had an influx of natural gas jobs
    — that growth has largely leveled off, as Pennsylvania hit this kind of steady state of gas production.”

    This isn’t the first time Pennsylvania’s core economic drivers have waned.

    Factories and steel mills took a beating in the 1970s and 1980s, as foreign producers competed in earnest with America’s industrial machine.
    Plants that sustained whole towns closed down, with nothing to replace them.

    The ironworks Andrew Carnegie built in 1875 still operates on the bank of the Monongahela River, but owner U.S. Steel is desperately trying to unload it to Japan’s Nippon Steel.

    These conditions have created new opportunities for the #clean #energy #transition to take hold.

    Political leaders like Democratic Gov. #Josh #Shapiro and business owners are embracing low-carbon industry as an economic development strategy for the energy-rich state.

    ✅Shapiro has pushed to strengthen the state’s outdated #clean #energy standard for #power #production,
    and he signed a bill this summer to establish ground rules for developing #carbon-#sequestration projects.

    💥His administration recently won $400 million in federal funding from the U.S. Environmental Protection Agency
    (“the second-largest federal grant in Pennsylvania’s history,” a spokesperson for the governor pointed out).

    Pennsylvania will disburse that money in competitive grants to industrial entities proportional to their ambitions at carbon reduction;

    ⚠️The Shapiro administration wants the ensuing projects to slash statewide industrial emissions 10 percent by 2050.

    Given the state’s long history of oil and gas, #hydrogen production is sure to loom large.

    In the lower-carbon future, clean hydrogen could become the next key energy commodity.

    Last year, Biden’s Department of Energy awarded seven proposed hydrogen hubs around the country roughly $1 billion each.

    Pennsylvania, as Shapiro regularly points out, was the only state to win funding for two:

    🔸The Philadelphia-based hub is slated to produce hydrogen with nuclear power and renewables,
    🔸while the Pittsburgh-based hub will focus on turning fossil gas into hydrogen and stowing the ensuing emissions underground.

  6. Ein neuer Ansatz, um die Verbreitung von #FakeNews zu bekämpfen, könnte in der „#Sequestration“ anstatt Verboten liegen. Dieses Modell sieht vor, dass Fake News in kleinen Netzwerken gefangen bleiben. Untersuchungen zeigen, dass Fake News nur in speziellen Fällen eine größere Gemeinschaft erreichen, wenn bestimmte Parameter erfüllt sind. Durch Anpassung dieser Parameter könnten Fake News effektiv in kleinen Gruppen isoliert werden, ohne die #Redefreiheit einzuschränken.

  7. "These data give us a new insight into the #evolutionary relationships between wood nanostructure and the cell wall composition, which differs across the lineages of #angiosperm and #gymnosperm plants. By identifying the potential selective pressures for the evolution of macrofibril morphology, our work provides the basis for selection or engineering for desirable wood properties and may open up routes for improved #carbon #sequestration in plantation forests."

  8. @davidho Will it be at the expense of ‘#sequestration’ by the #Fusion #energy boondogglers? They’ve had over SIX decades of successful ‘green’ 💰 sequestration!

  9. The urgency of implementing large-scale #tree planting is prompting funding of inadequately assessed projects that will most likely have negligible #sequestration benefits and cause potential social & ecological harm: theguardian.com/environment/20 #afforestation #reforestation #landuse

  10. Interesting read on Jigsaw farms in Western Victoria attempt to go #carbonNeutral. Soil #sequestration maxxed out, trees now older sequester less CO2. Reducing animal methane with seaweed additives needed. We need these farm solutions but we also need to move to a more plant based diet as IPCC highlighted

  11. Pläne den #Klimawandel mit Hilfe von #Aufforstung oder Abscheidung von #CO2 bei der Nutzung von #Bioenergie aufzuhalten stoßen schnell an ihre Machbarkeits-Grenzen:

    "In our new paper, published in Science, we assess the level of sustainability risks that could be triggered by the use of various different land-based CDR techniques, such as bioenergy with carbon capture and storage (BECCS) and afforestation and reforestation."

  12. Can soil #carbon sequestration in #grassland offset GHG #emissions from ruminants? Such #sequestration is time-limited. 2x the carbon in managed grasslands would be needed to offset continuous #methane & N2O emissions from the global ruminant sector: doi.org/10.1038/s41467-023-434 (1/2)
