Vorschlag für die Senkung der Netzengelte
Date: 2025.03.10
Vorschlag: Anstatt die Übertragungsnetze dauerhaft zu subventionieren, lieber kosteneffizienter bauen und ein Teil der Kosten mit einem Amortisationskonto um ein paar Jahre verschieben
Nach unserer Berechnung kann man mit kluger Planung etwa 92 Mrd. EUR (einen ,,Wumms'') sparen
Flexibility from biogas
Date: 2024.08.30
What flexibility do we need from biogas?
Shifting baseload generation by a few hours with small storage helps, but what we really need is seasonal flex by upgrading to biomethane/ol (and using most of it in other sectors).
A few thoughts on scaling, grids, liquids.
All your carbon shall be methanol

Arguments for mopping up all carbon in wastes and residues into methanol; use it to supply sectors that can't be electrified
TL,DR: methanol is liquid; easier to transport/store than CH4/H2/CO2; costs scale down nicely to multi-MW size
Burden of proof

In this post we provide some commentary on our recent paper "Response to 'Burden of proof: A comprehensive review of the feasibility of 100% renewable-electricity systems'".
