Green H 2 production reduces emissions by 80–95% compared to grey thus meeting the REDII directive. However, blue and turquoise fall short of this criterion without CO sequestration.
The planned steel industry shift from fossil-based production to low carbon alternatives will require millions of tons hydrogen. Hydrogen delivery large users calls for building new infrastructures. This study analyses five different hydrogen pathways including mill-site electrolysis, pipeline transport in and repurposed pipelines, synthetic methane, shipping various products. Costs, energy efficiency, greenhouse gas (GHG) emissions are evaluated using a mill consuming 144 kt as an example....
The EC 2030 Framework acknowledges that CCS may have an important role in reducing direct emissions from industrial processes on the scale needed longer term. In this paper potential of applying different CCUS concepts to applications Finland has been evaluated both economic performance as well emission reduction point view. overall CO2 industry heat and power sector were 2013 about 52 Mt which estimated biogenic comprise 24 Mt. results work show with a allowance price 50 €/t, would be...
Nutrients can be circulated back to agriculture from waste streams through anaerobic digestion and digestate processing. Digestate processing, however, is making slow progress as nutrient products have not been cost competitive compared fossil fertilizers designed the farmer's perspective truly match with regional need. In this study, aim assess apply mathematical optimization design of a cost-optimal processing route for biogas plant's produce fertilizer based on specified needs. Another...
The European Union's goal is to increase the share of renewable energy sources 20 per cent and that liquid biofuels for transport at least 10 by 2020. Liquid are, example, biodiesel bioethanol. Their use not assumed CO2-emissions in atmosphere. However, production processes fuels need causing indirect CO2-emissions. To evaluate environmental burden these it important consider analyses, too. This study defines Digestion process, Bioethanol FT-process (Fischer-Tropsch-process) Bio-SNG-process...
