Keeping the carbon: Biochar can be added to cement to sequester carbon within concrete. (Courtesy: Sabbie Miller) Topics: Biomass, Civil Engineering, Environment, Global Warming, Green Tech Replacing conventional building materials with alternatives that sequester carbon dioxide could allow the world to lock away up to half the CO2 generated by humans each year – about 16Continue reading “Carbon Storage…”
PV Caveats…
Graphical abstract. Credit: Joule (2024). DOI: 10.1016/j.joule.2024.01.025 Topics: Applied Physics, Chemistry, Energy, Green Tech, Materials Science, Photovoltaics The energy transition is progressing, and photovoltaics (PV) is playing a key role in this. Enormous capacities are to be added over the next few decades. Experts expect several tens of terawatts by the middle of the century. That’s 10Continue reading “PV Caveats…”
