Das ehemalige Nordsee-Ölfeld Nini wird ab 2026 als CO₂-Speicher genutzt.

#INEOS plant, jährlich bis zu 7,3 Millionen Tonnen #CO2 in leere Lagerstätten zu verpressen. Das Projekt #Greensand soll Europas erste voll betriebsbereite Offshore-CCS-Anlage werden.

#Umweltschützer warnen jedoch, #CCS dürfe kein Ersatz für echte #Emissionsreduktion sein.

This afternoon's bike trip was a 37 km round trip in one hour and ten minutes to collect a 20 kg sack of "greensand" olivine for the garden.

I think it's a good example of the efficiency of velomobiles: how they make human power even more effective than when riding a normal bike. Even on the return journey with a headwind and loaded with the sack of sand, it was easy to keep the speed above 35 km/h.

Being able to stow a lot of things inside the aerodynamic form of the bike helps a lot with efficiency. You feel extra weight when accelerating, not so much once you get going.

And why the olivine ? I calculated a few weeks back that in the worst case this last winter our heating could have emitted 105 kg of CO2. This sack is enough to absorb about a fifth of that amount from the atmosphere.

Each time we plant things indoors or in our garden we add a bit of olivine.

Once humanity (especially those of us in the highly emitting richer countries) has reduced emissions by a lot, it's possible to make a bit of a dent by using a product like this. But there's no chance of compensating for ever larger emissions by trying to mine ever larger amounts of olivine.

This morning's exercise ride was a 34 km round trip to collect another 20 kg sack of greensand. We've been using it with our house-plants, mixed with compost from the garden to start tomatoes, and here in the front garden it's levelled up the ground above our potatoes.

Over time, each sack permanently removes 20 kg of CO2 from the atmosphere and the process is beneficial to growing plants.

Three sacks make a very small difference to our historical emissions, but if I'm going to buy soil of some kind for the garden it may as well be this. I certainly won't buy #peat which would help to destroy an ecosystem somewhere and release CO2 into the atmosphere.

#Dänemark speichert #CO2 unter der #Nordsee

Der dänische Kronprinz Frederik gibt heute den Startschuss für die erste CO2-Einspeicherung unter der Nordsee. Warum das Projekt auch über die Landesgrenze hinweg interessant ist.

#Dänemark hat #Wintershall heute eine Lizenz für das #CCS Projekt #Greensand erteilt. Das Projekt ist ein weiterer Baustein in den klimaschädlichen #Wasserstoff-Projekten des Konzerns:

#WintershallDEA will aus #Erdgas Wasserstoff herstellen und das dabei entstehende #CO2 unter der dänischen Nordsee verpressen. Doch der als "blau" und sauber vermarktete #Wasserstoff bleibt klimaschädlich.

Wir vom #UmweltinstitutMünchen fordern: Keine Fördergelder für blauen #H2!
