ACT NOW OR WAIT FOR A MIRACLE
Climate change poses a major challenge to our society. The German per capita CO2 emissions are at an average of 9.6tCO2/a. The worldwide emissions target is between 2.0tCO2/a per capita in 2050. Quite horrifying considering that a holiday flight from Hamburg to Majorca (Spain) already causes emissions of 1.226kgCO2 for one person.
Some are still looking for "the" technical solution that solves this problem for us without having to change our habits. This might be the first problem. Nevertheless different concepts exists to deal with the problem. Just to name a few that have gotten the most attention recently. Shading of the atmosphere with giant satellite-like solar sails that are circulating in space around the earth, in order to reduce the solar radiation on our planet and thus reduce the Greenhouse effect. Or air filters, which filter out the CO2 and then enclose 2000m below the ground or the seabed. This is already known from industrial CCS systems at coal power plants.
Carbon sequestration through industrial CCS or CO2 air filtration considers the risks associated with safe and permanent storage to be a significant drawback.
CO2 sequestration critics argue that compression can increase heavy metal pollution in aquifers. Furthermore, according to a study carried out at Stanford University, the compression of carbon dioxide has a high likelihood of weak earthquakes. A further disadvantage of this technology is that significant amounts of additional CO2 emissions are generated for capture, transport and compression of CO2. Critics fear that leaks can even increase the CO2 content of the air significantly.
THE EMISSION TRANSITION
The complexity of the issue can not be discussed further here, but it should be emphasized that municipalities, farmers, foresters, wastewater treatment plant operators, energy contractors and much more can act now with the combination of existing systems and intervention measures. This has not only a positive impact on greenhouse gas emissions but also on the economic situation of the operators.
The implementation of many decentralized combined measures to reduce CO2 emissions worldwide has the effect of an "Emissions Transition" as a whole.
These measures include the following:
Reduce energy consumption / energy efficiency measures
Regenerative energies (generate and consume)
Compensate CO2 emissions (refforestation)
BIOMACON - Biological CCS
In a BIOMACON machine, heat is generated from biomass. A large proportion of the carbon is decoupled before combustion and therefore can not form CO2. About 1/3 of the total energy is removed from the system with the carbon. In contrast, in the case of biological CO2 sequestration, the loss
The use of carbon (biochar) is versatile. Due to its high porosity, this raw material is in demand for water and air treatment as well as for improving soil fertility. Under normal conditions, the carbon is stable for more than 1000 years.
In the case of biological sequestration, logistics takes place via the existing infrastructure.
Only the carbon is transported. One kilogram of carbon binds 3.6 kg of CO2
Climate change and our take on it
Carbon dioxide CO2 is permanently emitted into our atmosphere by us, the world population, or industry (energy, agriculture). Unfortunately, CO2 emissions also depend directly on the economic development of the regions. For this reason, especially industrialized countries are the largest issuers. Often it is addressed to the emerging countries, that they contribute the most to climate change and that environmentally harmful production conditions are one of the reasons for this. It is regularly forgotten in this debate, that the consideration of CO2 emissions per capita is much fairer for the country comparison. The following figure shows the output per capita for different countries. It is striking that in this comparison, the US has the highest per capita CO2 emissions of more than 15tCO2/a. Closely followed by Germany and Norway with approx. 9-10t/CO2/a.
