Greenhouse gas to combat climate change

There is enough talk of hydrogen as a clean fuel and it is true as long as it is generated with renewable and non-polluting sources. Although it has several problems, one of the main ones is its low energy density. However, we must also consider methane, which can paradoxically combat climate change. Although it is considered one of the worst greenhouse gases, however, if we produce biomass in low-cost agricultural areas such as deserts, we will be benefiting the environment and our pockets, it will allow to recover land, fix carbon dioxide, produce oxygen and also cheap and massive clean fuel. Which can be used in vehicles or injected into gas pipelines for distribution. In some cases, the energy need for its operation is higher than the energy produced from the process. In no case do we produce more waste to feed a biogas plant, therefore, its growth is limited

The cultivation of cactus biomass fixes environmental carbon dioxide, the methane in Biogas is the same molecule as natural gas, with the difference that it does not contribute carbon dioxide to the environment when burned, plants fix more carbon dioxide in photosynthesis than produced by burning methane, its balance is negative. Methane has 4 times the energy density of hydrogen at 350 bar, it requires a container 4 times smaller for the same energy. The equipment and applications are the same as natural gas. In internal combustion vehicles, their autonomy is similar to a vehicle with gasoline. 


The obvious question is if it is so good, why is it not used because of biogas?


Biogas is normally obtained from agricultural waste, manure, sewage, food scraps etc. Their function is environmental health and these plants are not economically profitable, they are only useful to dispose of waste or reduce operating costs by producing gas for combustion or electricity, they are not profitable.

The second alternative


It is a crop to produce energy in this case cactus biogas, which corresponds to a raw material developed by genetic selection to produce quality biomass and its transformation into biogas. These process plants are 15 times smaller than a manure biogas plant, and most importantly, they do not generate waste, the raw material is processed 100%. Only 10% of the energy produced is consumed in the process, 90% remains available. Therefore in this case they are profitable and economically attractive.


Climate change 


This crop combats climate change in several ways: It produces energy with a neutral balance in carbon dioxide, reforests arid areas, improves soil, retains moisture, multiplies life in areas where insects and birds can proliferate, in high-density and extensive plantations. they act as a buffer system or thermal buffer avoiding large fluctuations in temperature, they are basically a cactus forest. They are a brake on forest fires, the cactus is 85% water, a fire cannot spread. It allows to have permanent and local energy, avoiding transport over long distances. It can sequester 250 tons of CO2 / year / hectare.
