How to decarbonization in coal operation? 


Best insight from top research papers

Decarbonization in coal operations can be achieved through various methods. One approach is retrofit decarbonization, which involves adding carbon capture, fuel conversion, and replacing coal boilers with low-carbon energy sources while reusing existing equipment . Another method is co-firing coal with biomass, either through biomass gasification co-firing with pulverized coal (BGCPC) or biomass direct co-firing with pulverized coal (BDCPC) . Additionally, the use of vibrated gas-solid fluidized bed separation has shown promise in achieving efficient decarbonization of coal-series kaolinite . For coke oven gas and converter and/or blast furnace gas, a decarbonization method involving CO2 separation and cyclic regeneration of MDEA barren solution has been proposed . Finally, a coal gangue decarbonizing system has been developed, which reduces the carbon content of coal gangue without the need for other ores . These methods offer potential pathways for decarbonizing coal operations.

What are the aspects and facts of energy systems decarbonization?4 answersDecarbonization of energy systems is crucial due to the significant impact of industrial activities on climate change. Fossil fuels, contributing to 80% of global energy supplies, are a major concern for emitting greenhouse gases. Internal carbon pricing aids in cost-optimal decarbonization of facilities, but uncertainties in energy systems require robust solutions. Energy storage plays a vital role in achieving nearly complete decarbonization without compromising reliability or cost. To meet greenhouse gas reduction targets, a multi-faceted approach is necessary, with energy storage systems being key in transitioning to renewable-based power supply. Different storage technologies cater to various needs, from short-duration for solar energy integration to long-duration for seasonal energy shifts. Decarbonization strategies must consider ambitious emissions targets and local contexts for effective implementation.
What are the components of building decarbonization?5 answersBuilding decarbonization involves several components. One important component is the use of renewable energy sources, such as photovoltaic and wind turbine systems, to provide power for heating systems. Another component is the implementation of energy efficiency upgrades in buildings, which can significantly reduce greenhouse gas emissions. Additionally, the adoption of emission pricing policy instruments, standards and regulations, and complementary policies to facilitate the transition to low-carbon activities are crucial for effective decarbonization strategies. The integration of material flow analysis, building energy modeling, and life cycle assessment can also play a role in assessing the decarbonization potential of different strategies and prioritizing decarbonization efforts. Finally, the use of innovative technologies, such as decarbonization systems that atomize liquid for engine decarbonization, can contribute to reducing emissions.
What is ccus in decarbonization?5 answersCCUS, or Carbon Capture, Utilization, and Storage, is a suite of technologies that remove CO2 from the atmosphere and play a critical role in the process of decarbonization. It involves capturing CO2 emissions from various sources, such as industrial systems, power plants, and refineries, and then either utilizing the captured CO2 as a raw material for the production of valuable chemical products or sequestering it underground to prevent it from entering the atmosphere. The goal of CCUS is to reduce greenhouse gas emissions and combat climate warming by capturing and storing CO2, thus contributing to carbon neutrality. Offshore CCUS, specifically, focuses on capturing CO2 from emission sources and injecting it into sub-seabed geological reservoirs, permanently isolating it from the atmosphere. However, the deployment of CCUS on a commercial scale faces challenges such as economic costs and the need for technological innovations and investments.
What are the key factors that need to be considered in order to achieve decarbonization?5 answersAchieving decarbonization requires considering several key factors. First, there is a need for massive resource infusion and coordination between state and market actors to develop and diffuse deep decarbonization technologies. Second, policy design plays a crucial role in guiding the transition to a low-carbon economy. Policies need to be designed with market and technological investment risks in mind, and should aim to match problems and policies effectively. Third, a broad policy mix that creates reinforcing effects between climate and energy policies is essential. This mix can trigger technological innovation, restrict polluting activities, promote green growth, and ensure just energy transitions. Fourth, achieving decarbonization requires addressing the challenges of diverse energy resource options, varying levels of existing infrastructure, and societal readiness across different countries. Finally, behavioral transformations, institutional shifts, and action by a broad network of actors are crucial for successful decarbonization efforts.
Which are the decarbonization needs for the heting system?5 answersDecarbonization needs for the heating system include the development of carbon-neutral heat sources and technologies, such as hydrogen, that can compete with natural gas by 2050. Additionally, there is a focus on innovative consumer offerings and smart home technologies to drive the decarbonization of heating. Cost-effective decarbonization of heat is a grand challenge, and natural gas remains the cheapest heat source even after carbon capture, highlighting the need for dramatic reductions in the cost and availability of renewable energy for emissions-favorable electrification. In the electricity sector, deep decarbonization can be achieved through a high penetration of renewable sources like wind, solar PV, and hydro power, complemented by flexibility from hydro and storage facilities. Industrial decarbonization models lack certain capabilities to inform policymakers, such as cost, industrial, technology, and geographical coverages, and there is a need for transparency and accessibility of models and input data.
What is a decarbonized economy?2 answersA decarbonized economy refers to an economy that has significantly reduced or eliminated its carbon emissions. It involves transitioning from fossil fuel-based energy sources to cleaner and renewable energy sources, as well as implementing technologies and practices that minimize carbon emissions in various sectors such as industry, transportation, and power generation. The goal is to achieve a net-zero carbon emissions state, where any remaining emissions are offset by carbon removal or storage methods. Decarbonization strategies may include the adoption of renewable energy, energy efficiency measures, carbon capture and storage technologies, and changes in industrial processes. The decarbonization of energy-intensive industries, such as power generation, steel production, and cement production, is particularly important in achieving a low-carbon economy. Electrification of transportation and the use of direct air capture processes for CO2 are also key aspects of decarbonizing the economy.
