📽️ "It's at the heart of what we are doing." "This is really much more focused on industrial research, you could say and to establish the link between the academic and the industrial research is really one of my ambitions to make that really work" say Ed Buddenbaum and Guido Mul and much more In the movie from Arend De Groot | Sanjana Chandrashekar, PhD #green #hydrogen #

Today is the first day! ⚡ CIRCO Electrolysers is a GO! ♻️🌍 Right now, industries worldwide are ramping up electrolyser production to scale up green hydrogen. But there’s a hidden challenge in this transition—what happens when these systems reach the end of their lifecycle? Electrolysers contain valuable metals, advanced membranes, and composite materials that aren’t easily recycled. If we don’t act now, we risk creating a new waste problem—just as we solve another. 🚨 Will electrolysers be designed for circularity from the start? 🚨 Or will they follow the same linear path as so many other technologies? That’s why we’re launching CIRCO Electrolysers—bringing together key industry players to tackle critical questions like: 🔄 How can we extract precious metals from frames that would otherwise be mixed back into recycled steel? 🔄 How do we navigate regulations on PFAS and ambitious circularity targets? 🔄 How do we ensure Alkaline, PEM, and Solid Oxide electrolysers have end-of-life strategies? 🔄 How do we work together? We’re excited to work with some of the most innovative companies in the sector: Bosal Bosch Battolyser Systems Endress+Hauser Group HyCC Plug Power Powall Uniper VDL Groep Together, we will develop practical, scalable circular solutions to ensure electrolysers are built for sustainability from the start.

𝗕𝗮𝘁𝘁𝗲𝗿𝘆 𝟭𝟬𝟭🔋: 𝗪𝗵𝗮𝘁 𝗶𝘀 𝗡𝗠𝗖 𝗰𝗵𝗲𝗺𝗶𝘀𝘁𝗿𝘆? 𝗛𝗼𝘄 𝗱𝗼 𝗯𝗮𝘁𝘁𝗲𝗿𝗶𝗲𝘀 𝗯𝗮𝘀𝗲𝗱 𝗼𝗻 𝘁𝗵𝗶𝘀 𝗼𝗽𝗲𝗿𝗮𝘁𝗲? 𝗔𝗻𝗱 𝘄𝗵𝗮𝘁 𝗶𝗺𝗽𝗿𝗼𝘃𝗲𝗺𝗲𝗻𝘁𝘀 𝗮𝗿𝗲 𝗰𝗼𝗺𝗶𝗻𝗴? Here’s some of the key points. ---------------------------------- NMC is a battery material with layered structure The image shows what these layers look like. Lithium (red) sits between the transition metal polyhedra. The structure can remove lithium without breaking, which is key to its ability to work as a battery when combined with an anode which also stores lithium. On charging, the lithium moves from cathode to anode. NMC refers to three elements in this material: ➡ Nickel, Ni ➡ Manganese, Mn ➡ Cobalt, Co The general chemical structure is Li (Ni x, Co y, Mn 1-x-y) O2. This represents an evolution of the LiCoO2 (lithium cobalt oxide) structure, reducing cost by decreasing the cobalt quantity, and improving energy and lifetime. The key role these elements play are: ➡ Ni – increased energy density ➡ Mn – Thermal and structural stability ➡ Co – Corrosion resistance and stability The first commercial version of this material was NMC 111, which has equal quantities of Ni, Mn, Co. Since this a family of alternative materials has been developed, with continual drive to improve performance. These include but aren’t limited to: ➡ 33% Ni, 33% Mn, 33% Co – 𝗡𝗠𝗖 𝟭𝟭𝟭 (𝗼𝗿 𝟯𝟯𝟯) ➡ 50% Ni, 30% Mn, 20% Co – 𝗡𝗠𝗖 𝟱𝟯𝟮  ➡ 60% Ni, 20% Mn, 20% Co – 𝗡𝗠𝗖 𝟲𝟮𝟮 ➡ 80% Ni, 10% Mn, 10% Co – 𝗡𝗠𝗖 𝟴𝟭𝟭  ➡ 90% Ni, 5% Mn, 5% Co – 𝗡𝗠𝗖 𝟵 𝟬.𝟱 𝟬.𝟱 As the nickel content rises, so does the capacity – ability to store lithium ions per gram of material. However, the stability of the material can drop. Moisture sensitivity increases. Cracking of particles can lead to reduced cycle life or premature failure. Currently, batteries based on NMC are more expensive in $ / KWh than LFP (lithium iron phosphate). However NMC has a higher energy density at the cell level. What's next for this chemistry? Some examples: ➡ Combination with Silicon anodes ↳ Many companies looking at this for higher energy / faster charging. ➡ Improved particle coating. ↳ Eg Powall are developing continuous ALD processes to enhance performance ➡ Single crystal materials. ↳ Eg LG Chem ‘mid nickel’ NMC materials which can operate at higher voltages. ➡ Dual chemistry systems ↳ Eg Tesla have recently released a patent for NMC/LFP. In Summary: ➡ NMC describes Nickel, Manganese, Cobalt oxides ➡ Layered structure allows lithium storage ➡ In future: ⬆️energy density, lifetime. What excites you the most about this chemistry?
