Lidt om priser på energilagring
I sidste uge bragte Ingeniøren en artikel om et nyt koncept for lagring af elektricitet fra vedvarende energi. Når vinden blæser og solen skinner, og der er overskud af strøm, sendes elektrisk drevne togvogne op ad et bjerg i Californien. De er lastet med store betonklodser, som efterlades for enden af sporet. Her står de pænt og venter på, at vinden holder op med at blæse eller en sky går for solen, så er bliver underskud af strøm. På det tidspunkt sættes klodserne tilbage på togvognene, så de kan trille ned af bjerget igen, mens de elektriske motorer i togvognene producerer strøm.
Henrik Stiesdal reflekterer i dette indlæg på ing.dk over priser på forskellige former for energilagring og fremlægger samtidig sin simple beregningsmodel.
Energilagringsteknologier

Jon Fold von Bülow
Jon Fold von Bülow recieved his Cand. Scient. in Nanoscience from University of Copenhagen in 2011 and is currently working with upscaling Li- and Na-ion battery materials to the 100+ kg scale for Haldor Topsøe A/S.
Jon's main interest lies in energy technologies for the future and he started working with fusion energy at Risø National Laboratory for Sustainable Energy. He has since developed a growing interest in technologies that are closer to potential industrial application. He is a highly dedicated academic as well as a very active professional and have initiated and participated in many different projects.
His studies within nanotechnological material science and affiliation with Risø National Laboratories has taken him to Germany, China and the US, where he has collaborated independently with several international research groups. He has so far succeeded in pushing two academic projects to industrial application, first with the Danish company Coloplast A/S and recently with a California-based battery start-up – an invention that is currently being US patented.
Jon has conducted most of his work on Li-batteries in the facilities of California NanoSystems Institute (CNSI) as a research scholar at UCSB-MIT-Caltech Institute for Collaborative Biotechnologies (ICB). The manganese based cathode materials he fabricated during this period were all tuned for high-power applications and covers synthesis of various manganese oxides from solution, molten and solid states.
