Comments on: New CO2 Sequestration from Finland Yields Commercially Useful Materials

Hydrogen storage is possible, but it’s more likely that utility scale batteries will be how we power the grid when the wind is not blowing and sun not shining.

Using electricity to make hydrogen is very inefficient. You loose about half the power input. The machinery to make and use hydrogen is likely to be expensive.

Batteries are about 85% efficient. Batteries are likely to be cheap to manufacture. And very easy to incorporate into the grid.

Congrats and sorry. I do not have the space and the money for a battery system although we have some solar. There are many, many people who depend on grid supply I meant to say. I am sure you know some, too. We need both, decentralisation from individuals like you, CO2 use technology like from Finland or Germany – no pumping into the unseen!- and given all that we cannot quite leave the coal in the ground just yet, until we get little hydrogen generators scattered along the coastlines. Apparently the university of New South Wales developed a system whereby sunlight and seawater make hydrogen. If only we could get the alpha class (those with power, positions, and money) to make it happen…

This writing brought to you by solar power.

Stored for the dark hours in batteries.

I haz no coal. I haz electricity without it….

So you have electricity to write in.

So after digging up immense tracts of land to acquire coal, we’ll have to dig up immense tracts of land to acquire the feldspar to neutralize the emissions from the coal. Why don’t we leave the coal in the ground in the first place?
