🚨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."

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."

🚨What if we bet too much on future carbon removal tech and it doesn’t deliver?

New study shows that over-relying on #CDR like DACCS & BECCS could let fossil fuel emissions continue longer, delay action, and raise costs later.

Key findings🧵1/9 Image
2/ Many net-zero plans assume large-scale CDR. But techs like direct air capture (DACCS) & bioenergy with CCS (BECCS) are tiny today and scaling them is risky due to land, energy & cost barriers.
3/ Researchers ran 6 scenarios using GCAM:

-Stage 1: Plan for high or low CDR now
-Stage 2: Learn mid-century whether high CDR is actually feasible or not, and then adjust policy or not

They tracked emissions, energy shifts, costs & who bears the burden. Image

🚨A new study [preprint] shows that injecting sulfur at 50km could make #SolarGeoengineering much safer.

It cools the planet more effectively, speeds ozone recovery & avoids stratospheric disruptions. This could be done using a fleet of clean, reusable H2 rockets.

DETAILS🧵1/10 Image
2/ SAI involves spraying SO₂ into stratosphere, where it forms aerosols that reflect sunlight—cooling Earth. It mimics volcanic eruptions like Mt. Pinatubo (1991), which temporarily cooled the planet.

But current “SAI models” inject SO2 at a rate of 10 Tg/yr at ~25km altitude.
3/ But Injecting at 25 km creates problems

Aerosols accumulate in the tropical lower stratosphere, causing up to 6°C warming in that layer.

This disturbs jet streams, increases stratospheric water vapor, and delays the ozone layer’s recovery—by 25–55 years in Antarctica. Image
