➡️ Takeaway: Design choices matter as much as the technology itself—and uncertainty changes the story. 📄 doi.org/10.1016/j.gerr.2026.… #EnergyStorage #LCA #CleanEnergy #NetZero @MarkidesC @imperialcollege @ImperialChemEng @EnergyFuturesIC @Grantham_IC

⚠️ When uncertainty is included (Monte Carlo): 👉 Carnot (water) ≈ Li-ion Ranges overlap → no clear winner ❌ Thermal-oil Carnot batteries perform significantly worse (due to higher material + processing impacts)

✅ Water-based Carnot batteries outperform Li-ion in 13/18 categories 🌍 Up to ~23% lower climate impact (construction + end-of-life) ⚙️ Key driver: thermal energy storage systems → contribute >50% of total impacts → storage medium choice is critical

In our recent article in Microfluidics and Nanofluidics, we demonstrate how micro-mixer geometry and flow conditions control droplet breakup and flow regimes in liquid–liquid microfluidics, enhancing mixing efficiency and specific surface area. lnkd.in/e5tV2P4s

In a new paper published in @NatureComms, we propose a multi-#energy (electricity, heat, clean water) generation #photovoltaic #leaf concept with biomimetic #transpiration and show much-improved performance relative to competing #solar-energy solutions! doi.org/10.1038/s41467-023-3…

Check out our recent article in Nature Communications, where we apply energy system modelling to explore how solar PV-based mini-grids can interconnect with national grids and assess the investment risks posed by reduced electricity demand. doi.org/10.1038/s41467-025-6…
