Adaptation And Mitigation

The greatest lever for advancing climate adaptation and mitigation is the defossilization of energy systems. A key opportunity to replace fossil fuels across sectors is the use of renewable hydrogen. In this context, the main political and social push is currently on climate neutral hydrogen (H2) production through electrolysis using renewable electricity. Another climate neutral possibility that has recently gained importance is biohydrogen production from biogenic residual and waste materials. This paper introduces for the first time a novel concept for the production of hydrogen with net negative emissions. The derived concept combines biohydrogen production using biotechnological or thermochemical processes with carbon dioxide (CO2) capture and storage. Various process combinations referred to this basic approach are defined as HyBECCS (Hydrogen Bioenergy with Carbon Capture and Storage) and described in this paper. The technical principles and resulting advantages of the novel concept are systematically derived and compared with other Negative Emission Technologies (NET). These include the high concentration and purity of the CO2 to be captured compared to Direct Air Carbon Capture (DAC) and Post-combustion Carbon Capture (PCC) as well as the emission-free use of hydrogen resulting in a higher possible CO2 capture rate compared to hydrocarbon-based biofuels generated with Bioenergy with Carbon Capture and Storage (BECCS) technologies. Further, the role of carbon-negative hydrogen in future energy systems is analyzed, taking into account key societal and technological drivers against the background of climate adaptation and mitigation. For this purpose, taking the example of the Federal Republic of Germany, the ecological impacts are estimated, and an economic assessment is made. For the production and use of carbon-negative hydrogen, a saving potential of 8.49–17.06 MtCO2,eq/a is estimated for the year 2030 in Germany. The production costs for carbon-negative hydrogen would have to be below 4.30 € per kg in a worst-case scenario and below 10.44 € in a best-case scenario in order to be competitive in Germany, taking into account hydrogen market forecasts.

Adaptation And Mitigation

The role of adaptation and mitigation to climate change is described using the concept of planetary boundaries. The future evolution of the main reservoirs of carbon is described. The role of the land and ocean sink, the permafrost feedback and ocean acidification is described. The challenge to keep Earth’s temperature below 1.5 °C or 2.0 ºC is discussed. As this will involve large amounts of negative emission technologies, such as carbon capture and storage, this may be hard to achieve, as an analysis of their potential and environmental costs shows. Geoengineering has a separate of difficult problems to cope with, which makes the application non-trivial. Decarbonization of societies is discussed and an outline given for a transition path towards a carbon-free society.

AbstractIn this article I try to show that climate ethics must be to a great extent risk and energy ethics. As the emissions of carbon dioxide have to be stopped completely in a relatively short period of time a massive change of global energy systems is needed. Scenarios of how this can realistically be achieved must be developed and evaluated. The required transformations potentially conflict with the important aims of energy security, economic development and overcoming energy poverty. Proposed measures may involve unacceptable risks or be counterproductive. Criteria, principles and guidelines are proposed which are needed to deal with these problems. Finally, the difficulties and tasks of climate related energy ethics are critically exemplified on the strategy of comprehensive carbon capture and storage, a strategy which is part of almost all scenarios which aim at restricting the increase of the average global temperature to 2° C.

For significantly reducing greenhouse gas emissions, those from electricity generation should be negative by the end of the century. In this sense, bio-energy with carbon capture and storage (BECCS) technology in sugarcane mills could be crucial. This paper presents a technical and economic assessment of BECCS systems in a typical Brazilian sugarcane mill, considering the adoption of advanced—although commercial—steam cogeneration systems. The technical results are based on computational simulations, considering CO2 capture both from fermentation (released during ethanol production) and due to biomass combustion. The post combustion capture technology based on amine was considered integrated to the mill and to the cogeneration system. A range of energy requirements and costs were taken from the literature, and different milling capacities and capturing rates were considered. Results show that CO2 capture from both flows is technically feasible. Capturing CO2 from fermentation is the alternative that should be prioritized as energy requirements for capturing from combustion are meaningful, with high impacts on surplus electricity. In the reference case, the cost of avoided CO2 emissions was estimated at 62 €/t CO2, and this can be reduced to 59 €/t CO2 in case of more efficient technologies, or even to 48 €/t CO2 in case of larger plants.

The problem of global warming is a key challenge. One means to prevent climate change is to reduce the concentration of carbon dioxide in the atmosphere. This can be achieved using CO2 capture and storage (CCS) technology. Due to the relative novelty of the technology, low level of experience, and high risk of implementation, in practice society often displays a negative attitude towards CCS projects. Thus, it is necessary to develop a targeted strategy to popularize CO2 capture and storage technology. Based on an extensive literature review and the experience of implementation of CCS projects in different countries, this study demonstrates the necessity of applying the deficit, contextual, lay expertise, and public participation models to promote CCS technology. As a result, the factors influencing the choice of promotion tools are identified, and the measures to popularize CCS technology, depending on the stage of its implementation, are determined. Recommendations for the improvement of CCS public databases are developed. The methodologies used this study include case studies, system-oriented analysis, and stakeholder management tools.
