🚨NEW PAPER🚨

"A comprehensive #bioenergy accounting model with a multi-dimensional analysis was
developed in a new study based in #China by combining spatial, life-cycle, and multi-path analyses."

Summary in a 🧵 below ⬇️
1/6 Image
Accordingly, "the #bioenergy production potential and #GHG emission reduction for each distinct type of #biomass feedstock through different conversion pathways were estimated in the study."
2/6 Image
"The sum of all available organic waste (21.55EJ/yr) & energy plants on marginal land (11.77EJ/yr) in China produced 23.30EJ of #bioenergy & reduced 2535.32Mt CO2-eq emissions, accounting for 19.48% & 25.61% of China’s T energy production & C emissions in 2020, respectively."
3/6 Image
Furthermore, in this study, "life-cycle emission reductions were maximized by a mix of #bioenergy end uses based on #biomass properties, with an optimal 78.56% bioenergy allocation from biodiesel, densified solid biofuel, biohydrogen, and #biochar."

🚨A recent field study conducted over the Great Barrier Reef has provided key insights regarding sea spray aerosols (SSA).

For the first time, it shows that SSA can reach the cloud base height, advancing Marine Cloud Brightening (#MCB) research.

DETAILS🧵1/8 Image
2/ MCB is a proposed climate intervention that aims to reflect more sunlight by enhancing marine clouds.

The concept relies on artificially generated sea spray aerosols (SSA) at the ocean surface and their transport in sufficient quantities to low-level maritime clouds.
3/ A portion of the SSA that reaches cloud height can act as additional cloud condensation nuclei and modify cloud microphysical properties, potentially reducing the amount of solar radiation reaching the sea surface.

🚨A new 3-year study found that by combining crushed rock + compost + biochar could remove 51.7 million tons of CO₂e/year—just by treating 8% of California’s rangelands.
#ERW #CDR #biochar

Here’s the details:🧵1/9 Image
2/ Researchers spread finely crushed metabasaltic rocks across test plots in Browns Valley, California, in each of 3yrs.

Along with the crushed rock, some of the applications included compost or a combination of compost & biochar (burned pine & fir left over from local logging). Image
3/ Other plots were treated with only compost, and a group of control plots received no treatment.

Throughout the year, the team monitored each plot for levels of soil organic and inorganic carbon, pore water dissolved carbon, aboveground biomass, and greenhouse gas emissions.
