Carbon Burial Carbon Capture and Storage

1 Upvotes

Global CO₂ levels are rising faster than ever. As outlined in our Facts and Consequences pages, the time for action is now. But current global climate efforts are far from sufficient.

To make a meaningful impact, we must act on three fundamental strategies:

🌍 The Three Core Solutions

0. Raise Awareness - Nothing changes until people care. Spreading understanding of the urgency and scale of climate change is the foundation for any action.

1. Reduce Fossil Fuel Use - We must burn less oil, coal, and gas. This is the primary source of anthropogenic CO₂.

2. Capture and Store CO₂ - We need to actively remove CO₂ from the atmosphere through scalable, natural, and technological solutions.

3. Land Use Change - Preserve forests, stop deforestation, and reforest land globally to absorb CO₂ naturally.

So lets have a deeper look into Carbo Capture and Storage!

🌱 2. Capture CO₂ From the Air

Direct air capture (DAC) is energy-intensive and expensive — often >$300 per ton of CO₂. We need faster, cheaper solutions now.

✅ The best near-term solution: Biomass Burial

Nature already captures CO₂ for us — through photosynthesis. All we need to do is prevent that carbon from returning to the atmosphere.

2.1 Burying Dead Wood

  • Forests hold 295 Gt of carbon. Burying just 1.7% would remove 5 Gt of carbon — nearly half of the world's current CO2 emissions!
  • This could start with already fallen deadwood.
  • Costs are estimated at just $10–20 per ton — much cheaper than current carbon prices.

2.2 Wet Biomass Burial (e.g., Azolla)

  • Azolla is one of the fastest CO₂-absorbing plants on Earth.
  • Using water surfaces biomass can be grown on large scale and injected into geological formations.
  • The same can be done with all kinds of biomass or biological waste.

⚠️ Other Capture Technologies

  • Direct Air Capture: Scalable but costly and land/energy-intensive. It makes energy generation less efficient, why burn carbon in the first place.
  • Carbon Capture & Storage (CCS): Still only 45 Mt CO₂ captured annually. Requires 24–40% more fuel and is risky to store.

Direct Air Capture DAC has been done only on very small prototype scale. It is very energy intensive and it needs to store CO2 in gas form. It is very expensive with estimates between 300 to >1000$ per tonne of CO2. To sequester 1 Gt of CO2 35.000 square km of area would be required primarily for solar panels. To capture 40Gt of CO2 per year about 1.4 million square km would be needed (nearly the size of Lybia: 1,76 million square km). The amount of solar power would take up all the solar panel production for decades, as it represents about a third of the world's total energy production. 

Apart from that this does not seem to be very feasible, the amount of CO2 which needs to be put in gas form in the ground is enormous. There is the risk that the CO2 gets to the ground and kills people as it is heavier than air. In 1986 1700 people died in the Lake Nyos disaster when 100-300 kilo tons of CO2 were released. That equates to about 4 minutes of the above mentioned facility!

There is also CCS: Carbon Capture and Storage. There are only 45Mt Co2 captured this way in 2023. CCS requires a lot of energy, 24-40% more fuel are needed to produce the same amount of energy and then the process has only a 70% success rate. The better way would be to get rid of this power station entirely. The same problems with storing the CO2 in gas form apply. 

Conclusion: Biomass burial is the simplest, most scalable, and most cost-effective method we have today.

----------

So lets have a deeper look into Biomass burial. How feasible is it?

2.1 is a very low technology solution! It requires digging a whole in the ground, putting wood inside and covering it, such that the decay of wood is slowed down significantly. Instead of decaying within 10 years on the surface - and such that becoming CO2 again - it should last 100-1000 years in the ground.

It is especially interesting in countries where plant grow and decay fast and the average income is low. It is important that not the whole forest is cut down and buried, but only dead wood or certain trees which can be harvested to benefit the overall forest.

2.1) The world has about 40 Million square km of forest, which hold about an estimated 295 Gt Carbon. If only 1.7% of that mass is buried, 5 Gt Carbon equivalent to 18,35 Gt CO2 would be buried. Initially this can be achieved just by burying dead wood already lying on the ground. Then only 1 out of 50 trees is harvested every year.

2.2) If the fastest CO2 capturing plant (Azolla) would be used to produce biomass and this biomass would be pumped into the ground, then 21 tons of Carbon are buried per hectare per year. If the whole Mediterranean Sea 2.5 Million square km would be used in this way, then 5 Gt Carbon equivalent of 18,35 Gt CO2 would be buried. That is roughly less than half of what the world has produced in 2024. 

Strategy 2.1 is low cost, very simple and low tech. It only needs to be applied in the whole world. Most of these forests are in less developed parts of the world where the average income is quite low. The cost for burying of dead wood has been estimated in the order of magnitude of 10-20$ in North America! The prices for Carbon permits have traded constantly above 20$ the last 5 years and above 60$ since 2022. This seems to be a very viable source of income for a lot of people in the developing world!

Strategy 2.2 is probable also viable in some scale, but would require enormous areas of ponds to achieve a Gigaton Carbon impact. Also the technology requires more investment and infrastructure. 

The best, simplest and cheapest form of getting CO2 from the air is done by Mother Nature! We only need to incentivize enough people on the planet to harvest biomass and bury it in the ground on a large scale!

Discussion Designing cooling systems to reject heat at higher temperatures could help with decarbonization

2 Upvotes

The first law of thermodynamics states that energy cannot be created or destroyed. This means that all cooling systems reject heat as they work by removing heat from a medium in a given space. What prevents us from using this rejected heat for direct thermal applications is that the temperature is too low to be useful. The low temperature of rejected heat from cooling systems requires us to use an energy consuming heat pump to upgrade the heat to a temperature that is suitable for direct thermal applications. What if instead we choose to redesign cooling systems to reject heat at higher temperatures so that could avoid the energy penalty of a heat pump.

This is the barocaloric cooling cycle. This technology is already energy efficient and F gas free. This technology could act as the basis for developing cooling systems that reject heat at higher temperatures to enable them to function as useful heat sources

If we choose to pursue this in the future then we will end up making cooling systems dual use

  1. They provide cooling for refrigeration, air conditioning, gas liquefaction etc

  2. They produce usable heat for direct thermal applications

This could eliminate the need for separate cooling and heating systems.

If we pursue this then it will have the following benefits

  1. Elimination of natural gas for direct thermal applications

  2. Reduction of freshwater consumption by cooling towers to reject heat from cooling systems in industrial applications

  3. Elimination of all the costs associated with having cooling and heating systems being two separate systems

  4. Reduction of energy cost

Improving cooling systems to reject heat at higher temperatures will enable rejected heat from cooling systems to work as a decarbonization solution.

The effect of climate change on rising sea level was underestimated. This is just another case against emissions.

But the post asks a question on whether only policy measures can be effective in reducing CO2. What do you think? Do we need to look at our consumption pattern to realibly reduce CO2?

Facts CO2 fertilization effect exaggerated in Earth system models

Thumbnail pnas.org
2 Upvotes

Overestimated natural biological nitrogen fixation translates to an exaggerated CO2 fertilization effect in Earth system models by Sian Kou-Giesbrecht, Carla R. Reis Ely, Steven S. Perakis, and Nina Wurzburger.

In brief, the Earth system models, including climate models used in the IPCC report, have overestimated by about 11% the degree by which wild plants growth improves under higher CO2 aka CO2 fertilization. Although 11% does not sound huge, this shall significantly decrease the effects of land carbon sinks.

There is a video discussion at https://www.youtube.com/watch?v=ywxdWD6NqE8 which brings up some related work, including one paper that suggests methods for improving nitrogen bio-availability in natural eco-systems, but this paper says known methods appears highly ecosystem dependent.

Solution How to restore Earths climate

2 Upvotes

The only real solution to climate change is to restore Earths climate to its pre-industrial state. This is to be done by removing CO2 from Earths atmosphere once carbon neutrality has been established. We will need to first establish carbon neutrality by transitioning from fossil fuels to non-intermittent carbon neutral energy sources. After than we will need to use a carefully planned portfolio of CDR methods to return atmospheric CO2 to 280 PPM. We need to restore Earths climate if we choose to care about human civilization and the natural environment.

Here are the CDR methods we should use to restore atmospheric CO2 to 280 PPM once carbon neutrality is established

  1. Regenerative agriculture

  2. Biochar

  3. Enhanced Rock Weathering

  4. Turning fire prevention thinning waste into bio-oil and injecting this oil underground - https://heatmap.news/technology/charm-forest-service-carbon-removal

  5. Wastewater Alkalinity Enhancement

  6. Killing and sinking harmful algae blooms - https://carbonherald.com/first-ever-carbon-credits-from-toxic-algal-remediation-are-issued/

Direct air capture should not be used because it is energy intensive and does not have any co-benefits besides CDR.

All of the CDR methods listed above will need to be implemented at the same time acorss the entire world in order to restore Earths climate. We will likely need to use all six methods for at least 50-100 years in order to return atmospheric CO2 back to 280 PPM. In the meantime these CDR methods will each have their own co-benefits other than CDR which will make than beneficial to society rather than loss making activities.

Absolute restoration of Earths climate its the only acceptable climate action strategy if we truly care about present and future generations. We must accept that restoration of Earths climate is not a simple task but it need to be done to undo the mistakes of our past. If we reuse to fix the mistakes of our past then we will be betraying present and future generations whose quality of life will inevitably deteriorate due to climate change. We need to stop thinking according to the short termist plan of mitigation and adaption and start actual climate action.

Can We Predict Success Better Than a Job Interview?

Post image
0 Upvotes

At ReduceCO2Now, we've been experimenting with a different approach to recruiting.

We no longer conduct traditional job interviews.

Instead, we invite people to join our project meetings, collaborate with the team, and experience the project firsthand. The recruitment process itself becomes a practical test of motivation, teamwork, communication, reliability, and initiative.

Over time, we've collected data from more than 2,000 applicants from around the world.

Now we have an important question:

What can we learn from this data?

We're looking for:

• University professors
• PhD researchers
• Master's students conducting research
• Experts in organizational psychology
• HR researchers
• Industrial and organizational psychologists
• Data scientists interested in people analytics

Possible research topics include:

• Do interviews actually predict success?
• Which applicant characteristics correlate with long-term contribution?
• Can work samples outperform interviews?
• How can volunteer organizations improve recruiting?
• What predicts engagement, retention, and performance?

We believe many organizations still rely heavily on interviews despite growing evidence that structured assessments and work samples may be stronger predictors of future performance.

If you are interested in helping analyze this unique dataset, we'd love to hear from you.

Let's use data to improve how organizations identify talent and create opportunities.

Join us and help shape the future of recruiting.

Do You Want Your Children to Live in a World That Is Still Usable?

Post image
7 Upvotes

It's a simple question.

Do you want your children, grandchildren, nieces, nephews, and future generations to inherit a world where they can thrive?

A world with stable food supplies.
A world where extreme heat, droughts, floods, and wildfires are not constant threats.
A world where nature still exists beyond photographs and history books.

Most people would answer "yes" without hesitation.

The challenge is that the future is being shaped right now. Every year of delay increases the risks and makes solutions more difficult and more expensive.

The good news is that we already know a lot about the problem. We have talented people, scientific knowledge, engineering capability, and the ability to organize global action.

What we need is enough people who care and are willing to help.

So today's question is:

What do you think we should do to create a world that remains usable for future generations?

Share your thoughts in the comments. We are genuinely interested in different perspectives and solutions.

Earth's Blanket Is Getting Too Thick

Post image
10 Upvotes

The greenhouse effect is one of the reasons life exists on Earth.

Without it, our planet would be far too cold for humans, animals, and plants. Greenhouse gases act like a blanket around the Earth, trapping some of the Sun's heat and keeping temperatures suitable for life.

The problem is not the greenhouse effect itself.

The problem is that humans are making that blanket thicker.

By burning coal, oil, and gas, we have increased the concentration of CO₂ in the atmosphere from about 280 ppm before the Industrial Revolution to more than 430 ppm today. This extra CO₂ traps additional heat that would otherwise escape into space.

The result:

• Rising global temperatures
• More frequent heatwaves
• Melting glaciers and ice sheets
• Rising sea levels
• Changing rainfall patterns
• Increased risk of extreme weather events

Think of it this way:

A blanket keeps you warm on a cold night. Add a second blanket and you get warmer. Add a third, fourth, and fifth blanket, and eventually you become uncomfortably hot.

That is essentially what we are doing to our planet.

The science behind the greenhouse effect has been understood for more than a century. What has changed is the amount of greenhouse gases we are putting into the atmosphere.

The good news is that the same actions that reduce CO₂ emissions can slow the warming. Every ton of CO₂ we avoid helps reduce future temperature increases.

The challenge is large, but the solutions already exist.

What do you think is the most effective way to reduce greenhouse gas emissions globally?

We Stopped Doing Job Interviews. The Results Surprised Us.

Post image
0 Upvotes

Over the last months, we have been researching volunteer recruitment and team building for climate projects.

Like many organizations, we started with traditional interviews. We wanted to understand people's skills, motivation, and fit for the team.

Then we tried something different.

We stopped doing job interviews.

Instead, we invite interested people to join our project meetings directly.

They see the real project.
They meet the real team.
They experience how we work.
And we get to see how they collaborate, communicate, contribute ideas, and interact with others.

The results have been surprising.

Some people who interviewed extremely well contributed very little once they joined a project.

Others who might never have impressed in a formal interview became highly valuable team members.

We are currently analyzing the data and looking for someone interested in helping us evaluate our findings.

If you have experience in:
• Psychology
• Human Resources
• Organizational Development
• Statistics
• Data Analysis
• Recruitment Research

we would love to hear from you.

We believe there may be lessons here that apply far beyond climate projects.

Watch our short video:

Are job interviews still the best way to select people, or should organizations focus more on observing people in real work situations?

Land Is Warming Nearly Twice as Fast as the Planet Average

Post image
23 Upvotes

When people hear that Earth has warmed by about 1.5°C since pre-industrial times, many assume that is what they experience where they live.

In reality, much of the world's population lives on land, and land areas are warming significantly faster than the global average.

The graph from the German Weather Service (DWD) shows a striking example:

• Global average warming: about +1.5°C
• Germany's warming: about +3°C

Why the difference?

About 70% of Earth's surface is covered by oceans. Water absorbs and stores enormous amounts of heat, which slows temperature increases over the oceans.

Land behaves differently. It heats up faster and cools down faster. As a result, countries and regions dominated by land often experience warming rates that are far above the global average.

Germany is not unique.

Scientists observe similar patterns across Europe, North America, Asia, Africa, and many other regions. In many places, people are already experiencing temperature increases that are close to double the global average.

This is important because agriculture, water supplies, ecosystems, infrastructure, and human health are all directly affected by local temperatures, not by the global average alone.

Climate change is a global phenomenon, but its impacts are often felt most strongly on land where people live.

What changes have you noticed in your country over the last 20 years?

Why Do Some People Deny Human-Caused Climate Change?

Post image
8 Upvotes

The scientific evidence for human-caused climate change is stronger today than at any point in history. We can measure rising CO₂ levels, increasing global temperatures, melting ice, rising sea levels, and changes in weather patterns around the world.

Yet many people still reject or question the idea that humans are the main cause.

Why?

There are many possible reasons:

• Climate change challenges habits and lifestyles that people are comfortable with.
• Accepting the problem may feel like accepting personal responsibility.
• Some people distrust governments, corporations, media, or scientists.
• The impacts often seem distant until they affect us directly.
• Climate science is complex, and misinformation spreads quickly online.
• Many people simply do not realize how strong the scientific evidence has become.

Human psychology plays a role too. We often underestimate slow-moving threats and prefer information that confirms what we already believe.

What do you think?

Why do some people deny or reject human-caused climate change despite the growing evidence?

Please share your thoughts in the comments. We are interested in hearing different perspectives and experiences.

Germany Is Warming Nearly Twice as Fast as the Planet

Post image
118 Upvotes

When people hear that the Earth has warmed by about 1.3°C since the late 19th century, many assume that means temperatures have increased by roughly the same amount everywhere.

They haven't.

Because oceans absorb and redistribute large amounts of heat, land areas warm much faster than the global average. Since about 70% of our planet is covered by water, the global average temperature increase hides what people actually experience where they live.

Germany is a striking example.

According to data from the German Weather Service (DWD), Germany has already warmed by around 2.5°C since 1881. That is nearly double the global average warming.

This difference matters because most people, agriculture, infrastructure, and ecosystems are located on land. The warming we experience in our daily lives is therefore often much greater than the number reported for the planet as a whole.

The consequences are becoming increasingly visible:

• More frequent and intense heatwaves
• Higher nighttime temperatures that reduce recovery from heat stress
• Increased drought risk and pressure on agriculture
• Greater risk of extreme rainfall and flooding events
• Growing impacts on ecosystems and biodiversity

Global warming is not a future scenario. It is already measurable in Germany and across many other land regions around the world.

The good news is that the causes are well understood, and we already have many of the technologies needed to reduce emissions and stabilize the climate. Every tonne of CO₂ avoided reduces future warming.

Germany Breaks Nighttime Heat Record: 29.4°C After Sunset

Post image
41 Upvotes

Germany has recorded a nighttime temperature of 29.4°C, one of the highest overnight temperatures ever measured in the country.

Nighttime heat matters. Our bodies, homes, infrastructure, and ecosystems depend on cooler nights to recover from daytime temperatures. When temperatures remain extremely high after sunset, heat stress increases significantly.

This is exactly what climate scientists have warned about for decades.

Global average temperature has increased by about 1.3°C since pre-industrial times. Because oceans absorb much of the heat, warming over land is significantly higher. In many regions, including Europe, land temperatures have risen roughly twice as much as the global average.

The underlying driver is clear. Human activities have increased atmospheric CO₂ concentrations from about 280 ppm before the Industrial Revolution to more than 430 ppm today.

NASA ice core records show that for hundreds of thousands of years, CO₂ remained within a relatively stable range. We have now pushed far beyond that historical range, and the climate system is responding.

Heat waves that once seemed exceptional are becoming more frequent, more intense, and longer-lasting.

The good news is that we still have choices. Every ton of CO₂ we avoid emitting reduces future warming. Every solution we scale helps.

Discussion Growing oilseeds as cover crops

0 Upvotes

Regenerative agriculture is absolutely necessary if we want to adress climate change. We will need regenerative agriculture to protect our food supply from the effects of climate change in the immediate term. In the long term we will need regenerative agriculture to remove CO2 from the atmosphere and sequester it in soil so that atmospheric CO2 can be restored to 280 PPM. Regenerative agriculture cannot happen without cover cropping. We need to decide what crops to grow as cover crops in order to scale regenerative agriculture

One type of crop which we could grow as cover crops are oilseeds. Oilseeds are plants which naturally produce lipids and store them in there seeds. These plants do this to give their seeds a supply of energy for initial growth before photosynthesis can start. We can tap these lipids and use them to produce liquid fuels. The best way to do this without causing the indirect land use change is by growing such crops as cover crops. Cover crops are by definition grown on existing agricultural land in order to protect the soil during the off season.

Here are the criteria for determining if a oilseed plant can work as a cover crop

  1. Effectiveness at cover cropping in terms of soil health impact

  2. Oil content (30% is a good baseline to ensure efficiency)

  3. Wether of not the oil is edible or inedible to humans (inedible for biofuel)

If a oilseed crop meets all three of these criteria then it can be utilized as a cover crop with valorization of the seed oil after start of season harvesting

Crushing the seeds from these crops does not just yield oil. A solid material known as oilseed meal is also produced. This oilseed meal can be fed to livestock which in turn produces meat, dairy and eggs for human consumption. The wastewater produced during the crushing process should be anaerobically digested on site to produce biogas for use as fuel to produce the heat needed for the crushing process.

Here are some examples of oilseeds which can be used as cover crops

  1. Camelina - https://en.wikipedia.org/wiki/Camelina

  2. Carinata - https://en.wikipedia.org/wiki/Brassica_carinata

  3. Pennycress - https://en.wikipedia.org/wiki/Thlaspi

These oilseed crops are currently undergoing extensive research to see how well they can function as both cover crops and biofuel feedstocks.

Here is the idealized production pathway for biofuels from oilseed cover crops

  1. The Seeds are crushed with oil being sold off as biofuel feedstock and meal being sold as animal feed

  2. Seed oil undergoes cleaning, enzymatic degumming and enzymatic selective hydrolysis to make it suitable for pipeline transportation with the wastewater produced from this process being used to produce biogas to be burned to produce the heat needed by the process

  3. Seed oil is transported by pipeline like crude oil to large centralized biofuel production facilities

  4. These facilities use bimetallic catalytic reactors to hydrodeoxygenate the seed oils using hydrogen produced via self powering steam reforming of the bio-LPG byproduct

(The steam reformers are self powered via there own carbon monoxide output and also use bimetallic catalysts to reduce energy demand)

  1. The diesel and jet fuel produced by this process are sold on the existing liquid fuels market

A future cover crop oilseed economy will be a multi step system.

Growing oilseeds as cover crops will be a significant boast to both decarbonization and CDR. We would be able to enable soil carbon removal while at the same time producing carbon neutral liquid fuels to replace fossil fuel derived liquid fuels. The cultivation of oilseeds as cover crops should be considered a foundational aspect of climate action.
