The climate crisis we are experiencing, with high temperatures, long periods of drought, melting
ice, and more, has been proven to be linked to human-generated carbon dioxide emissions
since the Industrial Revolution. International organizations and governments are striving to
mitigate this phenomenon and prevent future disasters by establishing environmental
frameworks, while the scientific and technological communities are inventing solutions to meet
humanity’s energy needs sustainably.
A cornerstone of the response to the energy problem is the use of renewable energy sources.
This study focuses on a specific category of renewable energy (biofuels) and on the power-togas
technology. Specifically, it examines, through life cycle analysis, the upgrading of biogas
using the biocatalysis method, that is, the biological conversion of carbon dioxide into methane
in a Trickle Bed Reactor (TBR). The environmental impact of this process is then compared to
that of conventional biogas upgrading methods. Furthermore, the study compares the
environmental impact of biological biogas upgrading in a TBR when the energy source used is
the country’s energy mix, to the case when renewable energy sources are used to meet the
process’s energy requirements.
The study concludes that, given that the energy demands of conventional biogas upgrading
methods are significantly lower than those of biological upgrading, when the energy source
used is the national energy mix, conventional methods have a smaller environmental impact.
However, if the energy used comes from renewable sources, biological upgrading offers
significant advantages, most notably the simultaneous utilization of carbon dioxide during its
removal, something absent from conventional methods, which release or store the removed
carbon. Thus, when wind energy is used to support biological methanation, the process not
only avoids burdening the environment but has a positive overall impact.
