📰🌍🚀 Iran's strongest long-term energy asset may be the sun. New research shows how solar #PV could drive a cost-competitive transition across #power, #heat, #transport, #industry, and #desalination, while opening the door to a broader Solar-to-X Economy. @christianonre.bsky.social @lut.fi

📰🌍🚀 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

📰🌍🚀 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

📰🌍🚀 #Industry is hard to defossilize due to high energy needs, nonstop operations, and process emissions. #Hydrogen role may be overestimated, while solar #PV - being cheapest - could enable broad #electrification. @christianonre.bsky.social @lut.fi www.pv-magazine.com/2025/09/12/s...

A few days ago there was a nice milestone: 100 podcasts on research articles in my team! www.youtube.com/@ChristianOnRE and growing ... right now with 82 subscribers - pls feel free to join. Thx to all the many coworkers within the team & all around the world. Marius, special thx!

🔥New research on bifacial solar #PV modelling and power system impact. No game changer, but still valuable addition to the technology portfolio. @lut.fi

The most annoying part of being a researcher: Investing hours in adapting research proposals (for paying your own salary) to specific requirements and layouts of funders over and over again, so that a REVIEWER can kill it because he/she doesn‘t like it (w/o getting reviewer reports after rejection)🤦🏻‍♂️

"huge solar PV demand for Africa ahead" - that's what we find since year. The energy system solution for Africa is largely PV+battery as the core & most important backbone. Additional articles would be these ones: www.cell.com/iscience/ful... ; www.cell.com/joule/fullte... ; doi.org/10.1016/j.eg...

😎☀️Well this is good news! There is a huge potential ahead for Africa 🌍 (and South Asia): doi.org/10.1016/j.so... @christianonre.bsky.social

#Trump climate report has so many misleading information and false claims that it takes forever to read the entire #factcheck. @carbonbrief.org, well done 👍🏻

#ThrowbackThursday #TBT ☀️🍃⚡️ Over one year ago our study on the Seychelles introducing a new EnergyPLAN-based optimisation tool was published. Check it out (it‘s #OpenAccess) 👇🏻

📰🌍🚀 Wave power shows strong potential as a renewable source, especially for coastal and island regions. Complementary to solar PV worldwide, it could support hybrid systems. Islands may gain the most from combining wave power with solar PV. @lut.fi @christianonre.bsky.social

📰🌍🚀 The role of solar PV in Indonesia will extend; it will also include the production of e-fuels for hard-to-abate segments as alternative to land-intensive biofuel production. Various scenarios show the cost-competitiveness of solar PV in Indonesia’s renewable energy transition.

Cost-competitiveness for green hydrogen using intermittent renewable energy sources remains a significant challenge. Researchers have shown that considerable cost reductions can be achieved by optimizing plant control and design based on specific hydrogen demand targets and local weather conditions.

📰🌍🚀 To address the variability of renewable energy for a stable supply, 22 distinct types of flexibility options are found in 100% renewable energy systems research articles, categorized into power-to-X, energy storage, demand response, transmission and distribution grids, and curtailment. @lut.fi

📰🌍🚀 The WEO @iea.org has been a report on energy statistics and guiding future energy supply and demand developments. An examination of these reports indicates that even the progressive WEO scenarios vastly underestimate the growth of #RE, especially PV. @christianonre.bsky.social shorturl.at/YnORe

Here's a dye called Nile blue. It doesn't take much to stop a great deal of visible light from passing through. CO₂ acts in a different part of the spectrum (infra-red rather than visible), but basically does a similar thing.
