Carbon Capture (CCS)

Electricity From Carbon Dioxide

When I first read about the work of the University of Queensland research team claiming to create electricity from CO2, my initial thought was that this was a cross between a fossil fuel funded beatup and a fairytale. But, digging deeper, and talking with Dr Zhuyuan Wang of UQ’s ARC … [continued]

CCS Redux: Carbon Engineering’s Diesel? Just Put Electricity Into Tesla Semi Instead

For the same energy inputs you could travel 3 times as far for a 5th the CO2 emissions and well under half the cost in an electric truck.

Climatetech Startup Seabound Is Developing A Carbon Capture System For Large Ships

Here at CleanTechnica, we have written about electrifying personal watercraft and ferries — vessels used to cover short distances. Ocean-going cargo ships with all their containers are massive and need to travel much farther. It’s not possible to simply slap an enormous battery system and some electric motors in them … [continued]

Green Sharp Sand Beaches As A Carbon Drawdown Technology?

Carbon capture, direct air capture, and carbon direct removal are back in the hype cycle again, so yet again I’m looking at solutions that are technically interesting, if not remotely likely to scale. Under the microscope today is Vesta Earth, which is exploring olivine weathering as a beach sand supplementation … [continued]

CCS Redux: Carbon Engineering Was Always A Figleaf For Fossil Fuel Industry, Now It’s Owned…

Carbon capture and sequestration in all of its various ineffective, inefficient and expensive forms is having another run up the hype cycle. Nothing has really changed. The problems still exist. The alternatives are still better. The potential for use is still minuscule. And so, the CCS Redux series, republishing old … [continued]

Another Day, Another Suspect Ocean Carbon Capture Technology

Carbon capture is back on the hype cycle, years after it was last being pushed upon us as the only real solution to our climate change problem because . It’s a favorite of the fossil fuel industry for obvious reasons. Some of them are even saying the quiet part out loud, that it gives them the social license to not only continue to operate, but to actually increase extraction of coal, oil, and gas.

Electrolyzing Carbon Dioxide Out Of Sea Water Has Multiple Red Flags

In recent months I’ve returned to the overlapping subjects of geoengineering and carbon capture, both of which I’d mostly satisfied myself about years ago. Both, however, are re-ascending the hype scale and at least for aspects of geoengineering, my curiosity was unsatisfied.

CCS Redux: ExxonMobil’s CO2 Sequestration Is Just A Tiny Fraction Of Its CO2 Emissions

Carbon capture and sequestration in all of its various ineffective, inefficient, and expensive forms is having another run up the hype cycle. Nothing has really changed. The problems still exist. The alternatives are still better. The potential for use is still minuscule. And so, we’ve got this CCS Redux series, … [continued]
