🌍🔋 Grateful to have had the opportunity to contribute to this technical paper on critical materials for the renewable energy transition. 𝐂𝐨𝐧𝐬𝐭𝐫𝐮𝐜𝐭𝐢𝐧𝐠 𝐚 𝐫𝐚𝐧𝐤𝐢𝐧𝐠 𝐨𝐟 𝐜𝐫𝐢𝐭𝐢𝐜𝐚𝐥 𝐦𝐚𝐭𝐞𝐫𝐢𝐚𝐥𝐬 𝐟𝐨𝐫 𝐭𝐡𝐞 𝐠𝐥𝐨𝐛𝐚𝐥 𝐞𝐧𝐞𝐫𝐠𝐲 𝐭𝐫𝐚𝐧𝐬𝐢𝐭𝐢𝐨𝐧: https://lnkd.in/dyh9XiC2 The paper identifies and ranks materials essential for green energy technologies. It's a product of great vision and leadership by Indra Overland and terrific work by the whole team! 🤝 First, a meta-list of critical materials was compiled based on existing lists of materials deemed critical for renewable energy. Second, a composite index of criticality was created based on indicators such as market diversification, mineral abundance, and substitution potential. The composite index was combined with the meta-list to generate criticality scores as the basis for the global ranking of critical materials: 1.    Most critical: lithium, cobalt, copper, graphite, rare earth elements (REEs), others 2.    Moderately critical: silver, strontium, platinum, others 3.    Least critical: molybdenum, magnesium, others This work highlights the dynamic nature of material criticality and offers policy recommendations for future-proofing supply chains. 🔧 #RenewableEnergy #CriticalMaterials #EnergyTransition #Geopolitics #Innovation

Could Zinc-Bromine be a viable alternative to Li-ion? 🔋 With the shift to renewable energy, safe and efficient energy storage is crucial 🌍🔋 While lithium-ion batteries dominate, they're prone to saefty concerns particularly around fires 🔥 The flowless zinc-bromine battery (FLZBB) is a promising alternative. Researchers at Gwangju Institute of Science and Technology have developed a novel NMC/GF electrode, which suppresses the self-discharge issue that has plagued previous iterations of FLZBBs. This innovation boosts performance, achieving 96% coulombic efficiency and lasting over 10,000 cycles. 🔄 It offers a safer, cost-effective solution for energy storage, paving the way for more stable renewable energy systems. 🌿⚡ (Full Article -> https://lnkd.in/eZbAFukz) **For those interested: NMC/GF = nitrogen-doped mesoporous carbon-coated graphite felt #RenewableEnergy #EnergyStorage #BatteryTech

I'm thrilled to announce that last July I defended my MSc Thesis "Techno-economic model for Power-to-X hybrid plants", which has recently been awarded with a 10/10 grade with Honours. The .pdf file can be found on my GitHub repository: https://lnkd.in/dCThE6Zc ➡The thesis showcases an algorithm to find the minimum cost solution to produce #Hydrogen 🛢 or any of its derivatives (#Ammonia, #Methanol, #efuels ⛽). ➡ To find this solution, a Second-Order Cone Problem (#SOCP) was developed, taking into account variable renewable production, grid prices, #H2 storage and #BESS🔋. ➡Furthermore, a cutting-edge method for implementing both the electrolysis non-linear efficiency curve and the different states of the electrolyzer was included, diverging from the state-of-the-art solutions. BESS degradation was modelled as well. ➡The algorithm implementation onto #Pyomo and #Gurobi showcased that an optimal solution can be found in polynomial time, allowing for real time operations thus enabling its use in Power-to-X and electrolysis plants Energy Management Systems (#EMS). ➡The studied cases highlighted the harsh scenario of hydrogen projects, finding it difficult to reach profitability while maintaining low levels of risk. Hence, financial and regulatory aids must be granted to promote hydrogen implementation as #green #energy carrier. ➡Last but not least, I would like to extend my gratitude to Manuel García Plaza for believing in this tough project since the beginning and delivering helpful advice in the BESS modelling. Also, I would like to thank Guillermo Matute Gómez for sharing with me his deep understanding on Hydrogen systems and hourly dispatch algorithms. #Hydrogen #MathematicalOptimization #EnergyTransition

Valparaiso University undergrads demonstrate multi-year thermochemical energy storage Three and a half years after a group of undergraduate researchers at Indiana’s Valparaiso University stored heat at 1000°C, they have extracted the heat in a proof of concept demonstration of the extremely long-duration potential of the redox cycle for solar thermochemical storage. (How solar thermochemistry works). After storing reduced cobalt at room temperature for three and a half years, the re-oxidized material could be used to supply process heat directly or produce hydrogen with electrolysis by electrochemically oxidizing the cobalt in water. Their paper, Fungible, Multiyear Solar Thermochemical Energy Storage Demonstrated via the Cobalt Oxide Cycle, was published in the Journal of Solar Energy Engineering in April 2024. The idea that solar heat stored as chemical energy can be stored for long periods is not new, and this aspect of solar thermochemistry has been used in many redox reactions — including ceria and copper — which have already begun to generate startups to completely decarbonize commercial aviation and mining. But the Valparaiso University study with cobalt is the first time the concept has been demonstrated over multiple years. https://lnkd.in/da2W_jxb #CSP #solar #thermal #concentrated

A proprietary direct lithium extraction technology proposes using electrodialysis to produce lithium, green hydrogen, and fresh water from geothermal brines while repurposing oil and gas infrastructure. Meanwhile, new research reveals that deepsea polymetallic nodules generate oxygen through electrochemical processes at depths of up to 13,000 ft and may also hold valuable lithium and other rare metals. https://lnkd.in/dnZDYyTS

🔬 Stanford University researchers have made a breakthrough in developing liquid organic hydrogen carriers (LOHCs) for renewable energy storage. 💡 Key Insights from Research: 🌱 Led by Robert Waymouth, a professor of chemistry at Stanford, the team has discovered a novel, selective catalytic system for storing electrical energy in a liquid fuel without generating gaseous hydrogen. 🌱 The system uses isopropanol, a high-density liquid form of hydrogen, which can be stored or transported through existing infrastructure. 🌱 The team discovered that cobaltocene, a chemical compound of cobalt, is an unusually efficient co-catalyst in the reaction, delivering protons and electrons directly to the iridium catalyst. #RenewableEnergy #EnergyStorage #LiquidBattery #LOHC #HydrogenFuel #SustainableEnergy #StanfordUniversity #ScienceBreakthrough #CleanEnergy #EnvironmentalSustainability

🌍 Peak Oil: A Reality or an Overstated Concern? ⛽ As a master's student in Chemical and Petroleum Engineering, I’m continuously exploring the future of energy and sustainability. The concept of peak oil — the point at which global oil production reaches its maximum rate before declining — has been debated for decades. With advancements in extraction technologies, alternative energy sources, and evolving demand patterns, I wonder: 🔹 Are we truly close to reaching peak oil, or has this concept become less relevant due to innovations in energy exploration and renewables? 🔹 How might this impact energy security and the global economy in the coming decades? I’d love to hear perspectives from industry professionals, researchers, and fellow students. How are your organizations and countries preparing for this potential shift? Let’s discuss! #EnergyFuture #PeakOil #Sustainability #PetroleumEngineering #Renewables #EnergyTransition
