Abstract Germany 2050: For the first time reached a balance between its sources of anthropogenic CO 2 to atmosphere and newly created sinks. This backcasting study presents fictional future in which this goal was achieved by avoiding (∼645 Mt ), reducing (∼50 ) removing (∼60 carbon emissions. meant substantial transformation energy system, increasing efficiency, sector coupling, electrification, storage solutions including synthetic carriers, sector‐specific for industry, transport,...
Abstract To reach their net‐zero targets, countries will have to compensate hard‐to‐abate CO 2 emissions through carbon dioxide removal (CDR). Yet, current assessments rarely include socio‐cultural or institutional aspects fail contextualize CDR options for implementation. Here we present a context‐specific feasibility assessment of the example Germany. We assess 14 options, including three chemical capture six bioenergy combined with and storage (BECCS), five that aim increase ecosystem...
In its latest assessment report the IPCC stresses need for carbon dioxide removal (CDR) to counterbalance residual emissions achieve net zero or greenhouse gas emissions. There are currently a wide variety of CDR measures available. Their potential and feasibility, however, depends on context specific conditions, as among others biophysical site characteristics, availability infrastructure resources. our study, we selected 13 concepts which present in form exemplary units described dedicated...
A growing number of countries have set ambitious climate targets and recognized the potential CO2 geological storage. Brazil's goal is to neutralize carbon emissions by 2050. The Paraná Basin one most favorable onshore sedimentary basins for storage in Brazil. This extensive basin presents a privileged location south southeast regions, where largest stationary emitters are concentrated. Our results showed Rio Bonito Formation siliciclastic deposits present pairs reservoir-seal rocks with...
Power-to-gas-to-power technologies incorporating electrolysis, methanation, SNG-fired Allam cycles and subsurface storages allow for a confined circular use of CO 2 /CH 4 thus an emission-free seasonal storage intermittent renewable energy.
Carbon capture and storage will be necessary for some industries to reach carbon neutrality. One of the main associated challenges is design network linking CO2 sources sites. Establishing a can impacted by many uncertainties such as amounts, pipeline routes locations emitters sinks. We present framework investigate different scenarios future in Germany. The analyses compare costs scenarios. developed model uses several geospatial datasets an optimization scheme yield realistic...
Abstract Designing low-cost network layouts is an essential step in planning linked infrastructure. For the case of capacitated trees, such as oil or gas pipeline networks, cost usually a function both diameter (i.e. ability to carry flow transferred capacity) and length. Even for incompressible, steady flow, minimizing becomes particularly difficult topology itself dictates local material balances, rendering optimization space non-linear. The combinatorial nature potential trees requires...

Designing low-cost networks is an essential step in planning linked infrastructure. For the case of capacitated trees, such as oil or gas pipeline networks, cost usually a function both thickness (i.e. capacity) and length. Minimizing becomes particularly difficult network topology itself dictates local flow material balances, rendering optimization space non-linear. The combinatorial nature potential trees requires use graph heuristics to achieve good solutions reasonable time. In this work...
