Robust Distribution Network Reconfiguration Using Mapping-based Column-and-Constraint Generation
The integration of intermittent renewable energy sources into distribution networks introduces significant uncertainties and fluctuations, challenging their operational security, stability, and efficiency. This paper considers robust distribution network reconfiguration (RDNR) with renewable generator resizing, modeled as a two-stage robust optimization (RO) problem with decision-dependent uncertainty (DDU). Our model optimizes resizing decisions as the upper bounds of renewable generator outpu…

TPHE-Graphene: A First-Principles Study of a New 2D Carbon Allotrope for Hydrogen Storage
The shift from fossil fuels to renewable energy sources is essential for reducing global carbon emissions and addressing climate change. Developing advanced materials for efficient hydrogen storage enables sustainable energy solutions in this context. Herein, we propose sodium-decorated TPHE-graphene as a high-performance two-dimensional material for hydrogen storage. Density functional theory (DFT) calculations demonstrate that TPHE-graphene exhibits dynamical, thermal, energetic, and mechanic…

Unlocking the Future of Energy: How UK Flex Markets Are Reshaping the Grid
With more renewable energy—especially wind and solar—being integrated than ever before, maintaining balance between supply and demand in real time is a growing challenge. That’s where flex markets come in - and everyone from business to consumers is invited to have a seat at the table.

A mix of long-duration hydrogen and thermal storage enables large-scale electrified heating in a renewable European energy system
Hydrogen-based long-duration electricity storage (LDES) is a key component of renewable energy systems to deal with seasonality and prolonged periods of low wind and solar energy availability. In this paper, we investigate how electrified heating with heat pumps impacts LDES requirements in a fully renewable European energy system, and which role thermal storage can play. Using a large weather dataset of 78 weather years, we find that electrified heating significantly increases LDES needs, as o…

Oh it is frustrating when I can't find an article I thought I saved but didn't! It was 3 myths (or misconceptions) commonly held by people who are not climate change deniers. One was the myth that it would only affect future generations, a long time in the future. Two was that renewable energy could fix it. Can't remember number three. Does that ring a bell for anyone? #climatecrisis

Beyond Leaders and Laggards: A Typology of Renewable Energy Adoption Trajectories with Evidence from Off-Grid Communities
Understanding the dynamics of renewable energy adoption is essential for designing strategies that accelerate its spread - an urgent priority for advancing climate goals and improving well-being, especially in off-grid regions facing energy poverty. This study introduces a time-series-based analytical framework that quantifies and classifies adoption behaviors of geographic entities within a region. A novel metric, the Adoption over Time Index (ATI), captures cumulative adoption intensity and i…

Damping LFOs: Grid Following with Power Oscillation Damping vs. Grid Forming vs. PSS

Damping LFOs: Grid Following with Power Oscillation Damping vs. Grid Forming vs. PSS
Low-frequency oscillations (LFOs) present a significant challenge to the stability and reliability of power systems, especially in grids with a high penetration of renewable energy sources. Traditional grid-following (GFL) inverters have proven less effective in damping such oscillations. This paper presents a GFL-power plant controller with an auxiliary power oscillation damping control for damping LFOs. This approach is compared with a traditional power system stabilizer (PSS) for a two-area …

A better name for wind farms, solar parks, big hydro:
"Non renewable systems for capturing renewable energy flows."
Term used by Pedro Petro (cited by @… in his "The uncomfortable truths about the energy transition" (in Spanish).

Today in “silly billboards in my community”. The first is by the very “truthful” (/s) people at LNGfacts.ca. Of course, the word "LNGfacts" does not appear anywhere in the dictionary because it's made up nonsense. Just like the "fact" that LNG “makes Canada stronger”... like we're going to win the war in Ukraine with our LNG or fend off #TheAmericanFascist. (Note: LNG is a tool of fascists not the other way around)
This billboard used to say “BC LNG WILL REDUCE GLOBAL EMISSIONS”... with a link to ‘bclnghelps.ca' but that was so clearly a lie that they were forced by the courts to remove it and delete their website, but I made a website instead in their honour called: bclngburns.ca
Back to today's billbboard though... Here's a fact from February 2025: “European LNG imports fell by 19% in 2024 as gas consumption reached an 11-year low, thanks, in part, to renewable energy additions.” (#BCPoli #BCLNG #ClimateAction #ClimateEmergency #ExtinctionRebellion #LNG #NaturalGas #Europe #EU #Ukraine #Russia

Imagine you want to produce E-Fuels⚡⛽ but the power company does not want to sell you electricity⚡
That appears to be what potential E-Fuels producers faced in Iceland🇮🇸. The country uses 100% renewable electricity (hydro/geo) & could produce more.
Yet, Iceland's electricity producer Landsvirkjun does not have enough electricity⚡. Building new plants is delayed by slow permitting 📝. Landsvirkjun has therefore set out priorities.

Iceland's E-Fuels Controversy
Hydrogen and E-Fuels companies want to utilize Iceland's abundant renewable energy sources. But Iceland's largest energy company Landsvirkjun does not want to sell electricity to them. E-Fuels producers hope that European authorities will intervene, the EFTA Surveillane Authority investigates.

Anti-Net Zero Reform Mayor Andrea Jenkyns Urges Offshore Wind Investment
A Reform UK mayor who claims “net zero madness” is “bankrupting Britain” has called for investment in an offshore wind project “to boost growth” in the local economy. Dame Andrea Jenkyns, who was elected as Greater Lincolnshire Mayor in the 1 May local elections, has been a vocal opponent of climate action and renewable energy […]
