I wonder how this is even possible. Elsevier tells us at the proofing stage that changes in authorship are not possible anymore 🤔

Carbon dioxide removal benefits from solar PV Carbon dioxide removal is most likely needed for rebalancing the climate to comply with the 1.5 C target set in the Paris Agreement, as data suggest this level has already been breached on an annual b...

📰🌍🚀 CDR is most likely needed for the climate to comply with the 1.5C target. Beneath NCS and land use change, technological and bio-technical solutions are promising. Solar PV may play a key role for optimization even in unexpected places such as Iceland. @christianonre.bsky.social @lut.fi

This is important! To savely reach 1.5C we do not have any CO2 budget left, while low likelihood budget is also not plenty. @christianonre.bsky.social

Are these all full length research articles? Papers in IEEE journals are often relatively short. And what is the average peer-review time?

As always, it would be better to differentiate between fossil CCS, CCU, and CDR. Carbon capture as umbrella term is not suitable for this discussion.

Solar PV will have a major role in marshalling our productivity to create a sustainable civilization In all ages, humankind decided to spend considerable amounts of the available productivity on special monumental projects. Managing climate change and rebalancing within the planetary boundaries is su...

📰🌍🚀 Across history, societies devote major productivity to monumental tasks. Today, managing climate change within planetary boundaries is such a task, with the vast energy potential of solar PV emerging as a cornerstone of a sustainable civilization. @lut.fi @christianonre.bsky.social

Sodium-ion battery cells already near lithium-ion cost parity, set to get cheaper - Energy Storage By 2050, sodium-ion batteries with fast learning rates could deliver storage at 11–14 €/MWh - cheaper than lithium-ion at 16–22 €/MWh - while also offering higher energy-to-power ratios and high cycle...

It is interesting that never the cell chemistry is mentioned. Can it be a sodoum-ion solid state battery?

📰🌍🚀 Tropical islands can achieve #sustainable, secure economies through low-cost #renewables. #Solar #PV dominates due to strong resources and falling #costs, driving a transformative Solar-to-X economy for #energy and beyond. @lut.fi @christianonre.bsky.social

When will there be information available on the 4th conference on negative emissions, supposed to be hosted by IIASA next year?

The future arrived early: Why our energy cost forecasts need to catch up While solar modules and batteries have become icons of rapid progress, most energy models are still stuck in the past. A new global analysis shows that the cost of renewable energy has fallen far fast...

#Finland and the rest, pay attention to this 👇🏻 Nuclear power is not the way foward 👎🏻

DAC is largely needed primarily for CCU (e-fuels). Why novody thinks if that is a miracle - maybe because integrated assessment models do not include the technology - with the past bias of the @ipcc.bsky.social report on IAMs it not ended up in the last assessment report.

This would be true for a current policy scenario. Our study does not do this - but rather deploys a best policy scenario: Massive investments in renewable energy, net-zero emission system by 2050 and subsequent removal of 500 GtCO2 for 1.5°C and 1750 GtCO2 for 1.0°C by 2100.

When will information be available on the 4th int. conference on negative CO2 emissions - as I understood taking place next year at IIASA?
