Ziel bis 2030 ist etwa 15 bis 30 TWh an Speicher für Wasserstoff bereitzustellen. Weniger wie gedacht, aber besser wie nichts (Im Vergleich zum Rest). Das meiste wird trotzdem importiert werden müssen (fehlende Elektrolysekapazität). Aber duale Nutzung Erdgas/H2 (Kraftwerke/Speicher/Netze) möglich.

Danke für den Input. H2 eher als verbindendes Brückenglied zwischen den Technologien, ob zur Synthese von E-Fuels oder bei der Dünger- & Schwerindustrie aber auch als Speicher. Redox-Flow-Batterien brauchen (noch) Vanadium (v.a. aus China & Russland). Ohne Atom/Öl/Kohle wirds ohne H2 schwierig.

Wenden sich ab ist stark übertrieben. Auf jeden Fall die richtige Richtung, nicht auszudenken diese Länder würden wie bisher hpts. auf Kohle, Erdöl und Gas setzen. Weltweit größte Emittenten China 31%, USA 13%, Indien 8%, EU 7% -> pro Kopf USA 15t/CO2, Deutschland & China 8t/CO2, Indien 2t/CO2.

(H2) Wasserstoffgas ist trotz geringer Dichte eine der wenigen Technologien, die überhaupt in der Lage sind, Terawattstunden (TWh) über Monate (vom Sommer zu Winter) zu speichern. Batterien sind für diesen Zeitraum technisch und ökonomisch ungeeignet und es besteht große Abhängigkeit (hier China).

Bei H2-Einlagerung geringeres Speicherpotential wie Erdgas, jedoch verfügt Deutschland über ein sehr großes geologisches Potenzial an Salzstöcken, das weit über die aktuelle Nutzung hinausgeht. Der Neubau von Kavernen (zur H2-Einlagerung) ist fester Bestandteil der Nationalen Wasserstoffstrategie.

I believe this was a dead or dying red alder although honestly I couldn't bring my eyes to look up as I was so mesmerized by these gorgeously upsetting orange slimy looking slime mold. Note the shelf fungi to the left of the trunk.

These bright orange colored slime mold exhibited a slimy exterior that I failed to touch to confirm their feel. These interesting creatures are hanging off of the moss that covers this dead/dying tree.

I was so confused and excited when I spotted these. The trunk had been sectioned into segments of no greater than 4 ft in length. The entire exterior of this stump as well as another cut section on the other side was covered in these adventitious roots. The trunk looked nowhere near capable of being alive enough to shoot these out. Maybe I'm wrong and these are actually related to another plant that is taking advantage of the sturdy nature of this cedar trunk but the only thing that makes sense based on how they look and their being on multiple sections of the same trunk is that it was the cedar sending out one last desperate hope of a root to be able to regrow their roots to gather more nutrients and grow once again. I wonder if this section was repositioned cut/rooting side down, if the tree could end up growing again. Fascinating find, at least to me.

I believe these are hanging slime mold, Badhamia utricularis. Found trailside at Murdock Beach Access on the N Olympic Peninsula.

The last photo is a first for me. Adventitious roots growing from the sapwood of this very old heavily weathered sectioned cedar trunk. 🍄📸 #SlimeMold #Nature #Trees

Speicher(problem): (Aktuell) Pumpspeicher ~ 25 GWh, Batteriespeicher ~ 25 GWh. Potential Erdgasspeicher (H2 umrüstbar) ~ 40 bis 80 TWh (1000x), Gasnetze sind H2-ready/umrüstbar neue Gaskraftwerke auch. Fernwärmeausbau (viele Möglichkeiten), Netzausbau gehören zum Konzept der EE-Überschussverwertung.

Chinas Botschaft in London: Spionagegefahr durch Keller neben Datenkabeln?

Fig. 2 (shortened, full legend in paper): Plasmodesmata at different cell interfaces in C4 monocot leaves. (A) In contrast to C4 eudicots, C4 monocots can be one or combination of either NADP-ME, NAD-ME, and/or PCK subtype depending on the decarboxylation enzyme present in the bundle sheath (BS). Confocal micrographs (leftmost panel) were obtained using an excitation wavelength at 633 nm and dual emission wavelengths at 650–720 nm (magenta for Photosystem II) and 720–800 nm (blue for Photosystem I) to visualize chloroplasts. Note that BS cells of C4 NADP-ME and C4 PCK leaves have agranal chloroplasts (see second panel from left) thus appear pseudo-blue under confocal microscope due to reduced Photosystem II content. The cell wall (green) was visualized at an excitation wavelength of 405 nm and an emission wavelength of 420–480 nm.

On Earth, avalanches are terrifying. On the Sun, they are simply overwhelming.

ESA's Solar Orbiter captured this magnetic avalanche on the Sun as it triggered a major solar flare. There's an outline of the Earth at the beginning for scale.
