Green iron and aluminum as recyclable energy carriers in circular economy - From global opportunities to solid fuel combustion physics
Green iron and aluminum as recyclable energy carriers in circular economy - From global opportunities to solid fuel combustion physics
Abstract:
The transformation to a net-zero carbon society is one of the most pressing challenges of our time. Green metal fuels, produced from metal oxides using renewable energy, are emerging as a carbon-free, high energy density replacement for fossil fuels due to their availability and recyclability. Iron and aluminum in particular iron and aluminum are promising options for a carbon-free cycle since they are non-toxic, safe to transport, easy to store, abundant, and in principle can be recycled an unlimited number of times.
This plenary will deliver two key messages:
1. Iron and aluminum are promising carriers of renewable energy for a net-zero carbon society.
2. While previous work on solid carbonaceous fuels provides an excellent starting point for studying metals as energy carriers, the physics of iron and aluminum combustion is quite different, fascinating, and largely unexplored.
In the first part, iron and aluminum are introduced as a recyclable chemical energy carrier. During the reduction of metal oxides, energy from renewable sources such as wind, hydro, and solar is stored. This energy is released again through combustion in air or steam. This yields either high-temperature heat (air) or high-temperature heat and hydrogen (steam). The product of this zero-CO2 combustion process is solid metal oxide. One promising application of metals is the retrofit of existing infrastructure. This is demonstrated with a thermodynamic system analysis for a coal-fired power plant to be operated with iron powder in the future. This is followed by a techno-economic analysis, for which different partner countries for reduction and oxidation are considered. Hydrogen and iron are compared as energy carriers based on round-trip efficiency and levelized cost of electricity.
In the second part, selected experimental and numerical results on the combustion physics are presented. First, the oxidation of single iron particles is showcased, and the different phases of ignition and combustion are discussed with a special focus on the coupling of gas phase transport with the condensed phase kinetics. Similarly, the fascinating physics of aluminum-steam combustion are explored. Going towards multidimensional flames, discrete and continuous flame propagation modes are analyzed. Finally, results for turbulent iron-air flames are presented. The need for well-controlled and well-characterized experimental conditions to reduce uncertainties is demonstrated by comparison to simulation results.

Data and Digital Twins for Sustainable Renewable Fuel Combustion
Data and Digital Twins for Sustainable Renewable Fuel Combustion
Abstract:
Decarbonizing industrial heat, particularly in sectors like steel, glass, cement, and aluminium, presents a critical challenge in the pursuit of global energy transition goals. This challenge is amplified by the reliance of these industries on high-temperature heat, which is difficult to electrify, making the exploration of alternative decarbonization strategies essential. Digital twins have emerged as a powerful tool with the potential to revolutionize the modelling and optimization of complex combustion systems in these industries. By integrating physics-based constraints, data assimilation techniques, and sparse sensing, digital twins can provide accurate and reliable predictions of system behaviour under various operating conditions.
This presentation delves into the development and application of digital twins for practical combustion systems, with a focus on enhancing their predictive capabilities for improved efficiency and reduced emissions. We explore the use of physics-based, data-driven approaches for the development of digital twins capable of continuously integrating heterogeneous data streams and providing estimates of prediction uncertainties.

Cofiring biomass with coal in China: Progress, perspectives and challenges
Cofiring biomass with coal in China: Progress, perspectives and challenges
Abstract:
The extensive utilization of coal in China is the major reason for the large emissions of CO2. To achieve the ambitious goals of "carbon peak and carbon neutrality", decarbonization of coal-fired power generation is an important and urgent task. China has abundant biomass reserves, but its utilization is still at a low level. Using biomass to partly or completely replace coal can not only increase renewable energy utilization, but also accelerate the decarbonization of coal-fired power generation, which has great strategic significance for building a new and sustainable power system. Since the 1990s, biomass-coal cofiring technologies have been greatly developed and widely applied in developed countries and regions such as Europe, the United States, and Japan, with the United Kingdom even achieving 100% biomass combustion in large coal-fired power plants. In comparison, China's experience in this area is still very limited. However, in recent years, the Chinese government has successively promulgated a number of policies to encourage cofiring biomass with coal for power generation.
This presentation first introduces the progress in practicing biomass-coal cofiring in China. Secondly, the significant importance and broad prospects of this technology in China's "carbon peak and carbon neutrality" strategy are elaborated. Finally, it points out the challenges associated with cofiring biomass at high ratios, and discuss possible countermeasures based on international experiences.

Emerging issues in turbulent combustion of low carbon fuels
Emerging issues in turbulent combustion of low carbon fuels
Abstract:
Energy systems across the world are changing at a fast pace, with demands for low or zero net carbon energy conversion. Wind and solar dominate the growth of primary energy delivery, while a number of solutions are proposed for the particularly difficult problems of long-term seasonal storage. Hydrogen, ammonia and liquid synthetic fuels are proposed solutions, although their production costs are still outside the competitive range.
An increasing number of studies on laminar and turbulent combustion of such fuels have been launched to both understand their properties relatively to well-studied fossil fuels. The investigations have opened further windows into the role of differential diffusion of both large and small molecular weight fuels in turbulent combustion, as well as the continuing challenges of predictions in the combustion of blends.
In this talk, we will survey at the current state of the art in experimental and modeling studies of low carbon fuels and blends, showing successes and pointing the way to further challenges

Energy and mobility sustainability
Energy and mobility sustainability
Abstract:
Energy and Mobility sectors are responsible for more than 3/4 of the global green-house gases emissions. Combustion is still widely used in many so called “hard-to-abate” sectors. They include both energy production and energy intensive industrial sectors as well as terrestrial, marine and aeronautical propulsion systems. While it is commonly forecasted that combustion free processes and technologies will allow for a significant reduction of GHG emissions, the present picture hardly suggests that this goal will be reached in the next decade. According to realistic scenarios combustion will continue to play a central role in many industrial sectors and will be used in propulsion for many years to come. Cleaner combustion processes, carbon neutral fuels exploitation, efficient and fuel flexible processes and devices will be still developed in the next years. The lecture aims to outline the main motivations and critical issue that research in combustion has to face with to support this developments.
