Also, to put the 36 thousand tons of CO2 the plant can capture into perspective: The average German person emits ~11 tons CO2 per year. Hence the plant can remove the yearly carbon output of ~3300 German citizens.

So the worlds largest plant will not even be able to compensate the carbon put out by a small German town…

Here's some more good news on our efforts to stop global warming.

A new road resurfacing material which enables the production of net zero asphalt has been used in the UK for the first time, in County Durham.

The material incorporates a carbon negative aggregate and recycled asphalt planings from another scheme in County Durham, contributing to a circular economy and demonstrating our commitment to sustainable solutions.

Capturing CO2 to put into the building materials that we need in order to build more efficient and resilient buildings and infrastructure is a win/win!

Austria’s ‘first large-scale carbon capture’ to turn emissions into construction materials.

The ‘circular’ process will be made possible by the ‘first industrial large-scale carbon capture and utilisation (CCUS) plant in Austria’!

So, I'm quite resigned to not being able to entirely restore the reputation of carbon offsets using carbon dioxide with everyone and I entirely appreciate the damage that has been done to this budding new part of the circular economy we need to transition into.

@jgkoomey @matthewtoad43 since y'all have been some of the fiercest opponents to this new industry, I'm curious what you think of this American University's group rebranding.

To me biochar is one of the most promising Direct Air Capture Carbon Dioxide Removal technologies because it is so accessible to the most people to take part in especially all of the farmers that we need to recruit into the struggle to transition away from fossil fuels and to minimize greenhouse gas emissions.

So, I am intrigued to see how this rebranding will go for this ivory tower think tank.

C'mon man. Just because some people oversold some offsets over a decade ago is no reason to trash an important aspect of our response to global warming.

And that you keep asserting that is too expensive just indicates that you've not spent a minute learning about or enhanced rock weathering, but whatever.

This graph of falling prices for batteries is all the reason anyone should need to justify making the decision to pause building new LNG export terminals.

Renewable energy and storage can replace all of our fossil fuel use for electricity production, heating, and industry.

This isn't a novice-level entry into the world of biochar and its potential role in helping to reverse the global warming we've caused and the two presentations are quite bland by most modern standards, but I really like this graphic that Nikolas Hagermann shared to help explain pyrolysis.

There’s no scenario in which rich countries buying land in developing countries to offset the rich countries’ carbon emissions is a good thing.

Just wait till they do this for engineered CO₂ removal () like direct air capture ().

Climeworks' collective mission is to remove a billion tons of carbon dioxide from the atmosphere by mid-century.

And while we love doing what we do, our driving force is climate science and the unequivocal truth that the world needs massive carbon removal to keep temperature scales within check.

Tangible

Wind and solar are close towards gaining 2 points per year of the global electricity production market share. At that rate of gain, global wind and solar production would only reach 30% of global electricity by 2032 so we all have to do what we can individually by helping to reduce the fossil fueled electricity and power we're responsible for being produced more quickly.

April 2019: 9.37%
April 2020: 11.12%
April 2021: 11.86%
April 2022: 14.57%
April 2023: 15.94%

CleanTechnica interviews USBI's Tom Miles about opportunities to repair our climate and help fix our agriculture industry using as one of our carbon dioxide removal technologies. The article's author is correct in that biochar is a deep and amazing rabbit hole, but the crucial aspect is that biochar is that it converts about 50% of the carbon in organic waste into a stable compound that stays locked in the soil.

Anyone know a SPI DAC breakout that's as ubiquitous in Arduino land as the MCP4725 I2C DAC?

Looks like the MCP48xx or MCP49xx might do it, but haven't found a module for these yet... bit it might be that just hooking up a 8-pin DIP is simple enough anyway...

Have you heard of Carbon Dioxide Removal and Direct Air Capture ?

Stopping to emit greenhouse gases just as fast as we each possibly can is the most important step, but along with that we've already emitted far too many so we've got to remove gigatonnes!

Measurement, Reporting, and Verification – the three most important letters in CDR – as a tool for justice and transparency that gives communities a clear view into how our technology works. https://www.heirloomcarbon.com/news/the-new-climate-economy-needs-rules-of-the-road

I know that I have a steep hill to climb in order to help Carbon Dioxide Removal recover from the damage the and just plain grifters have done to the reputation of Direct Air Capture .

I'm hoping that the tangible product can help to convince people to reconsider DAC for CDR.

The demonstrated recalcitrance of terra preta and ability of any and every farmer/gardener to manufacture and sequester it makes it one of my favorite approaches.

Oh yeah, related to Direct Air Capture and biochar, today when I should have been doing something else I ran into this new small start up from up where I went to get my Master's in soil microbiology.

This looks like a quite nice small-scale pyrolysis system. Of course the price is steep for a new product like this, but I hope that they'll be able to convince a bunch of cannabis growers making good profits to become early adopters.
