The SUNKRAFT Bioenergy - Concept




Why bioenergy?

Fossil fuels are still cheap and available in large quantities.

So far, mankind has not reached the "limits of growth" that Meadows postulated in 1972, and oil production has not plummeted after the "peak oil" has been exceeded. Coal stocks will not run out in the foreseeable future either.

So - why bionergy?

There is absolutely nothing to support the assumption that new deposits of fossil fuel will be tapped forever, from which the world can be supplied with cheap energy sources. On the other hand, these fuels come from a few sources that are strategically important and whose accessibility has to be guaranteed more and more often by military means.

The fossil carbon that is released in large quantities when fossil fuels are burned must be returned to the natural cycle in order to avoid the undesirable effects of CO2 in the atmosphere.

Apart from that, not only energy sources such as oil, natural gas and coal are important, but also nutritional elements such as nitrogen, potassium and phosphorus, without which adequate nutrition cannot be ensured, whereby potassium and phosphorus must also be counted among the indispensable, fossil raw materials. The same applies of course to arable soils, what ist the essential precondition for agriculture.

Unfortunately the established economy is only scarcely sustainable and will be subjected to significant restrictions at some point due to the fact that indispensable raw materials are becoming scarce and therefore expensive and, on the other hand, problematic waste products are accumulating, as is already indicated with CO2 and plastic waste

The bioenergy economy can help here, since many energy crops, unlike most food and feed crops, are perennial and fix both carbon and nutrient elements in the long term and protect the soil from devastation.

In addition, this concept farming can also provide us with raw materials from renewable sources, for example with much less durable plastic as recently.


Bioenergy and Sustainablity

Bioenergy is nothing but solar energy, which is bound as high-energy plant biomass. Although this can also be done with technical methods, bioenergy has the advantage that a field is much closer to nature than any industrial wasteland. In addition, the energy is directly available in an easily storable form, whether as a fermentation substrate, biofuel or fuel.

Of course, the advantages of bioenergy are scarce if simply the classic food- or feed-crops for energy purposes are used. But there are more and more alternatives available, such as the Silphium perfoliatum instead of energy maize, "double zero"-rapeseed instead of sugar beet, which produces not only expeller as cattle- and swine-feed, but also plant oil for food or biodiesel, short-rotation plantations give us not only energy wood, but also poplar fluff that can replace cotton. Other undemanding oil and fiber plants should also be mentioned here, such as hemp.

The bioenergy economy opens up completely new markets and fields of activity for farmers. The farmer thereby becomes - also - an energy and raw material farmer who produces food, feed, energy and raw material plants, whereby the question of a contradiction between "tank or plate" does not arise because the Circular economy requirements or "permaculture" are obeyed and makes the concept highly environmental-friendly.

Bioenergy from biogas is an important component in the conversion of our energy supply to sustainable sources, since in contrast to wind and solar power plants, biogas plants also supply energy in the dreaded "dark doldrums", but can also be throttled temporarily if there is a surplus of wind and solar power ,

In the process, biogas plants regain the nutrient elements contained in the fermentation substrate, which are then returned to the field with the digestate and thus returned to the natural cycle. SUNKRAFT Bioenergy offers appropriate consulting and advice for biogas plants to ensure smooth operation and to propagate the most advanced methods.

Bioenergy and Self-Sufficiency

In many cases the claim is made to achieve self-sufficiency at national or at least at EU level through bioenergy. So far, however, this has not become apparent since the areas in densely populated Central Europe are nowhere near sufficient. With this demand, bioenergy is clearly overloaded, so one should be very reluctant to make any promises.

But this is not a disadvantage, since a reliable supply of the population would not even be guaranteed with food if no oil for agricultural machinery and no phosphorus were imported as a nutrient element. Here, too, bioenergy can help, since the nutrient elements are better circulated and not lost to the previous extent and must be replenished accordingly.

Anything that cannot be produced yourself can still be bought in from the outside, since the bioenergy economy also brings a number of advantages for other countries, especially in tropical developing countries:
