Human-induced landscape modification in the in the last two centuries in the Po delta plain (northern Italy)

Historical maps with high degree of accuracy permit quantitative reconstructions of past land use and land cover (LULC), crucial to assess the impact of human activities on landscape evolution. After georeferencing in a modern reference system, the Carta del Ferrarese commissioned by Napoleon Bonaparte and completed in 1814, has been used to quantify the changes in LULC, occurred in the last two centuries in the Po delta plain. The map depicts a palaeo-landscape dominated by wetlands (49% of the study area) and agricultural areas (41%), whereas forests appear already largely depleted (5%). The Piantata Padana, a traditional agroforestry system with live trees used to support grapevines, is dominant (62% of the agricultural areas). The comparison with the 2014 LULC map highlights a dramatic reduction (85%) of wetland areas and the replacement of the Piantata Padana with bare arable lands, with the consequent removal of 4-40 million trees. Soils of areas formerly occupied by wetlands show high organic-carbon content, highlighting the potential of humid areas in carbon sequestration. Land reclaiming, prompted by the introduction of steam pumps, favoured the economic development of the area, but concurred to CO2 emissions through the oxidation of soil organic substances, energy consumption from pumping stations, and the extensive use of hydrocarbon fuels in agriculture. Although urbanisation is limited in the Po delta plain, this area appears nowadays largely shaped by human activities, with the dominance of lands devoted to agriculture, dissected by a dense network of draining channels. The landscape changes recorded in the last two centuries in the Po coastal plain have been uniquely driven by human activities, like in several coastal plains worldwide.

Direct-hydrocarbon solid oxide fuel cells with novel BaCe0.8Fe0.1Ni0.1O3-δ-impregnated NiO-GDC anode prepared by phase-inversion method

A phase-inversion method prepared NiO-GDC anode is coated by a novel perovskite material of BaCe0.8Fe0.1Ni0.1O3-δ (BCFN) via a solution impregnation to enhance the resistance of carbon deposition of the anode for direct use of hydrocarbon fuels. After a reduction in H2, the anode consists of a Ni-GDC scaffold in a straight-pore structure covered by BCFN with exsolved FeNi3 nanoparticles. With the BCFN/Ni-GDC anode, the polarization resistance of the cell is 0.034 and 0.11 Ω cm2 at 650 °C in dry H2 and dry CH4, leading to a peak power density of 720 and 475 mW cm−2, respectively. This cell performs stably in dry CH4 at 400 mA cm−2 and 650 °C for 425 h without noticeable voltage decrease and carbon deposition in the anode. In dry C2H6 at 650 °C, the cell voltage decreases linearly with time by 20 % within 390 h, which is attributed to carbon deposition in the anode.

The concept of transitioning centralized heating systems in multi-apartment buildings to decentralized electric water heating

In recent years, there have been significant changes in the perception of the feasibility of using electricity as a source of thermal energy for household heating systems. Electric boilers are considered an important element in the energy transition from the use of hydrocarbon fuels to renewable energy. For a modern comprehensive approach in assessing the feasibility of various heating systems, it is necessary to consider not only the operational costs but also the energy, environmental, economic requirements, safety of operation, and maintenance costs, from both the consumer’s perspective and in terms of the historically evolved role of the state and the social significance of providing heating to the population. This study compares these factors for centralized heating systems, apartment-based systems using wall-mounted gas boilers, autonomous systems using boilers on different types of fuel, and water electric heating systems. Conclusions are presented on the advisability of gradually transitioning the heating supply of multi-apartment buildings from centralized to individual apartment-based electric water heating.

La1.5Sr1.5Mn1.5Ni0.5O7 ±δ Vs La1.5Sr1.5Co1.5Ni0.5O7 ±δ: Exsolved Materials as Anodic Layers for Direct Biogas-Fueled SOFC

Currently, one of the main problems in commercial SOFC systems fueled directly with hydrocarbon compounds, such as biogas, is the high risk of blocking the active phase on the anode side (e.g. Ni-YSZ) due to carbon formation/deposition during the conversion of fuel into power energy. This issue causes a lowering in the overall performance and durability of the cell. Therefore, to overcome this deactivation mechanism, it was successfully demonstrated that an additional anodic active layer in commercial SOFC using materials based on exsoluted perovskites could be an interesting and viable alternative. This asseveration is based on the fact that using this kind of material is possible to get heterogeneous surface systems with highly stable and electrocatalytically active embedded nanoparticles uniformly distributed on the surface with a high carbon coking tolerance in a hydrocarbon fuel atmosphere.This study aimed to evaluate and compare the electrocatalytic behaviour of two new catalytic materials with Ni exsolution for direct dry biogas-fueled SOFC. The starting materials were Ruddlesden-Popper-type based on a nickel manganite (La1.5Sr1.5Mn1.5Ni0.5O7±δ or LSMN) and nickel cobaltite (La1.5Sr1.5Co1.5Ni0.5O7±δ or LSCN). Both materials have been synthesized by the Pechini method using stoichiometric amounts of precursors as nitrates. Once the respective gels have been formed, they were treated in the air at two dwell temperatures, 300°C for 2 h and 500°C for 3 h, to ensure the total elimination of the organic compounds. Finally, the resulting powders were treated in air at 1300°C for 12h and then, physicochemically characterized. For the electrochemical characterization, the as-treated powders were mixed individually with Gd0.1Ce0.9O2 (CGO) in a weight ratio of 70:30 using a ball milling for 6h. Finally, to get the slurry for the coating layer, each mixture (LSMN+CGO and LSCN+CGO) was ground for an additional 2h in the presence of 8 wt % of triethanolamine, 2 wt % polyvinyl butyral resin (BUTVAR B-98) and 2-propanol. Commercial button SOFC cells by InDEC® (anode-supported cell Ni-YSZ/YSZ/LSM) were painted on the anode side getting an active area of 2 cm2. The experiments were carried out at 800°C with pre-conditioning using diluted H2 and then, with simulated dry biogas. A Biologic tool was used as a device for the electrochemical measurements.The purpose of this communication is to present the results of experiments with two button cells derived from the same large area commercial cell (anode supporting cell) coated with the two electrocatalysts developed in this work. The electrochemical test carried out for more than 200 h demonstrated that this external functional layer on the anode side contributes to getting a stable potential within the whole working time at the selected galvanostatic conditions (500 mA cm−2). By comparing the results of these two tests, the exsolved LSCN layer showed better perfomances, because of the the B-site doped with Co instead of Mn which is responsible for an enhanced O2- transport within the crystal structures. Finally, post-reaction characterization revealed minimum/null carbonous species in both cases which suggests that the classical risks caused by the direct use of hydrocarbon fuels in commercial SOFC can be suppressed with this kind of approach which would lead us to think about the use of this type of materials in a next level or further electrochemical applications.

Natural Gas Flaring Management System: A Novel Tool for Sustainable Gas Flaring Reduction in Nigeria

The use of hydrocarbon fuels increases with population growth and rising standards of living, and so does natural gas flaring. Natural gas flaring is both a waste of natural resources and a violation of Nigeria’s energy policy for sustainable development through natural gas conservation. However, it remains the most cost-efficient and effective associated natural gas (ANG) management option in developing countries such as Nigeria. The World Bank’s initiative to eliminate routine gas flaring by 2030 has increased the need to limit or eliminate routine gas flaring. Often, studies on natural gas utilisation techniques fail to consider the lack of practical tools that integrate economic, technical, and regulatory factors into a gas flaring management framework, and the intricacies of existing tools, which often come at the expense of simplicity to achieve real-time information output. This paper aims to establish a framework and ANG management tool to reduce regular gas flaring in Nigeria. This research established a management framework (using a flowchart decision tree) and models to provide a user-friendly ANG flaring tool (using a MATLAB graphical front end user interface with back-end ASPEN HYSYS thermodynamic models). This was combined with techno-economic models for liquefied natural gas, gas-to-methanol, and gas-to-wire ANG utilisation options. The tool was then tested with data obtained from Fields Y and X in the Niger Delta region of Nigeria. The results, considering both economic and technical factors, showed that the choice of liquefied natural gas for Field Y was best due to its proximity to the pipeline infrastructure and its cost-effectiveness, and the availability of a high-demand LNG market for that area. For Field X, gas-to-wire was best due to its proximity to the electrical grid and high electricity requirements for that area. Additional geographical profiles in West Africa and ANG utilisation alternatives were recommended for further investigation. This paper developed and validated a one-of-a-kind ANG flaring management tool that incorporates techno-economic analysis of selected ANG utilisation options to assist operators and investors in making more profitable investment decisions.

메탄연료 공급 저온 고체산화물 연료전지를 위한 코스퍼터링법으로 제작한 백금-루테늄 촉매 기능층에 관한 연구

Solid oxide fuel cell is a next generation energy conversion device that can efficiently convert the chemical energy of fuel into electrical energy. Fuel flexibility is one of the advantages of SOFCs over other types of fuel cells. SOFCs can operate with hydrocarbon type fuel. While nickel based composite is commonly used in direct methane fueled SOFC anode because of its great catalytic activity for methane reforming, the direct use of hydrocarbon fuels with pure Ni anode is usually insufficient for facile anode kinetics, and also deactivates the anode activity because of carbon deposition upon prolonged operation. In this report, the Ni based anodes with 20 nm thick catalytic functional layers, i.e., Pt, Ru, and Pt-Ru alloy, are fabricated by using the co-sputtering method to enhance the anode activity and power density of direct-methane SOFC operating at 500℃.

A polyester-based initiation strategy for achieving high-efficient cracking of hydrocarbon fuels

Active cooling of scramjets by endothermic hydrocarbon fuels is considered as an effective approach to addressing the thermal problem for hypersonic aircrafts. To accelerate the endothermic cracking reactions of these fuels for a better cooling capability, a strategy for hydrocarbon cracking using polymer-based macromolecular initiators has been proposed. To verify the universality of this strategy and also to enhance the solubility of macromolecular initiators, a novel polyester macromolecular initiator (MI) is designed. It is clarified that the MI features high-efficient thermal cracking of hydrocarbon fuels in a tubular reactor with an improved conversion ratio, gas yield, and alkene selectivity. The possible mechanism behind the macromolecular initiator is revealed on the basis of intermediate analyses and density functional theory (DFT) calculations, which show the radical fragments from MI decomposition are effective in accelerating JP-10 dehydrogenation. The successful implementation of polyester materials in hydrocarbon fuels holds immense promise for the optimal use of hydrocarbon fuels in hypersonic aircrafts.

Impact of Carbon Deposition on Diffusion Parameters in Porous Anodes of Solid Oxide Fuel Cells Using the Lattice Boltzmann Method

A solid oxide fuel cell (SOFC) is an electrochemical device that converts energy of a chemical reaction into electrical and thermal energy. Besides lack of pollutants and high electrical efficiency, one of the main advantages of SOFCs is the flexibility of using a wide range of fuels, i.e., natural gas, biogas, or any reactant with hydrogen as constituent. However, the use of hydrocarbon fuels can affect the transport phenomena within the SOFC porous anode due to carbon deposition. The purpose of this work is to investigate, at pore-scale level, the impact of carbon deposition on the microstructural parameters that describes the diffusion process. The single-phase fluid flow behavior through digitally generated SOFC anodes is obtained by the Lattice Boltzmann method (LBM). Diffusion transport parameters, i.e., porosity, gas-phase tortuosity and effective diffusion coefficient are computed for different content of carbon deposition to be able to evaluate its impact.

Long-Term Operation and Post Analysis of a Stack with Methane Fuel

In the commercialization of the solid oxide fuel cell (SOFC) technology, the long-term stability and the use of hydrocarbon fuels are important. An 18-layer SOFC stack with anode-supported cells was first designed, assembled and operated in Huatsing Power Co., Ltd in China. After the basic performance test with H2, the stack was operated at 750 °C with a 14.53 L/min hydrocarbon fuel for nearly 800 hours. The voltage degradation rate was only 1.42%/kh. Post analysis was performed through SEM and EDS. Microstructures of Ni particles with different degree of carbon deposition at the fuel inlet were observed and discussed. A phenomenon of rainbow-shaped color distributions on the surfaces of anode and nickel mesh in every layer was found. This phenomenon was related to the oxidation of the upper part of the nickel contact layer. Due to the light interference taking place at the nickel-oxide-air interfaces, different thickness of oxide film led to different colors. Carbon deposition and oxide film of nickel contact layer with non-uniform thickness were the possible causes of degradation.

Formation of the component composition of blended hydrocarbon fuels as the problem of the multi-objective optimization

The problem of energy efficiency has always been the most significant in the economy. Its solution is related to the technologies of many industries. The most significant are the reserves of energy efficiency of the use of hydrocarbon fuels, which are observed at all stages of production of high-energy hydrocarbon fuels. This is largely due to the extensive scientific search for alternative energy sources and stagnation in the conduct of search and fundamental studies of the processes of producing motor fuels from hydrocarbon raw materials. A new energy-efficient technology for the production of high-energy, low-freezing hydrocarbon fuels for the Arctic was created by solving the problem of multi-object optimization.

Energy, Environment, and Social Development: Recognizing Sustainability Excellence in Oil and Gas

President's column The term sustainability is widely used. Unfortunately, when applied to hydrocarbon energy sources, it is often mentioned in a negative way. Too often, the focus is on reducing the use of hydrocarbon fuels, or measuring the emissions resulting from burning of hydrocarbon products. This unbalanced approach ignores key aspects of sustainability—aspects where the oil and gas industry makes significant positive contributions. A sustainable world is one in which everyone has enough to eat, access to energy, educational and social opportunities, health and safety, and so much more. If a key goal of sustainability is improving people’s lives, then the three key ways to support that goal are a strong economy, a healthy environment, and social development. Our industry has a very positive story to tell in each of those pillars. Instead of participating in the discussion around who or what is to blame for the world’s ills, we can show leadership in talking about what we have done, are doing, and will continue to do to improve people’s lives through our operations. The world economy will continue to run on oil and natural gas for decades to come. The companies in our industry make enormous investments to ensure that we can meet growing world energy demand. According to the International Energy Agency’s (IEA) World Energy Investment 2018, the oil and gas industry invested more than $2 trillion in the past 4 years to achieve a reliable supply of energy, despite the downturn and reduction of oil prices during the same period. Technology has allowed us to unlock shale resources around the world, develop smaller deposits economically, and find resources in new areas. Continued innovation will help us get more oil and gas from known reservoirs. Far from being a dying industry, our technical success will continue to feed the growing global economy. At the same time, our industry has helped to relieve energy poverty. The IEA reports that an additional 120 million people around the world gained access to electricity in 2017. As a result, the total number of people without electricity access fell below 1 billion for the first time ever. The availability of natural gas for power generation has been an important factor in this achievement. No industry is without impact. Our industry has been innovating ways to reduce our environmental footprint and enhance safety for years, and we continue to invest in technologies to do even better. Through industry organizations such as the International Oil & Gas Producers (IOGP) we are able to share best practices and report our successes. IOGP recently reported an exponential decline in fatal accidents in the oil and gas industry, even as activity rose significantly around the globe.

Study of Recent Manufacturing Trends towards Smart Automobile Vehicle

This chapter describes these themes and thereby the current situation in the manufacturing landscape the current manufacturing industry is already transforming changing social mindset and government aim for sustainable production. This general trend is accompanied by globalization, increasing competition and changing markets, which manufacturing companies need to cope with. Next to these general trends the developments on ‘Lean Manufacturing’, ‘TQM’ and ‘Logistic innovations’ are more and more accepted supported by the ongoing acceptance of Information and Communication Technology ‘ICT’. As mentioned this ICT developments are more and more visible in the inbound and outbound logistics of companies. Nowadays the manufacturing companies of Current time even cannot function without ICT guided logistics. Significant technological development has taken place, changing and reinventing how motor vehicles have been produced in the last 79 years. The manufacturing processes are now adopted to play greater role towards developments as aesthetical, aerodynamic, ergonomically comfortable design, with low periodic break down, highly fuel efficient and least pollution emitting motor vehicles. The complete process lines are almost undergoing automation to ensure quality, durability and cost effectiveness, resulting better future by way of sustainability of energy as well as adding to Fuel Saving & release of low emission to reduce Health hazards & Ecological imbalances. Since the fast depletion of fossil fuel has now a day become worldwide problem and technology has generally led to a greater use of hydrocarbon fuels for about 150 years, thus the decrease in supply of fossil fuel is making civilization vulnerable. The use of large number of vehicles for transport is also contributing to about 70% of total air pollution. In India vehicular pollution has also reached 8 times than it was 20 years before. Currently India is the fifth country which produces higher rate of emission and creating environmental & ecological imbalance after rating of USA, China, Russia & Japan. The world wide researches are going on and Japan has taken leading role for development of automobile vehicles at large. This paper covers the history of technological developments, use of CAD / CAM in designs, use of modern techniques for manufacturing processes & unconventional machining processes for vibration free, low noise and most balanced engines, use of sensor devices, development of alternative fuel efficient & low pollution automobile engines, tapping all other non conventional energy sources to develop fuel cell, battery operated, photocell and compressed air motor vehicles for future.

Applications of the Glycine Nitrate Combustion Method for Powder Synthesis on the LSGM-based Electrolyte-Supported Solid Oxide Fuel Cells

Solid oxide fuel cells (SOFCs) are recognized as environmentally friendly, highly efficient devices, and alternatives to conventional energy conversion systems. Typical material design used is the YSZ-based cell consisted of NiO-YSZ and LSM as anode and cathode, with a dense electrolyte of YSZ. When considering the use of hydrocarbon fuels, carbon deposition has been observed as major failure issue. Ce0.6Mn0.3Fe0.1O2 (CMF) has been studied recently because of the high tolerance against coke deposition and it also exhibited high catalytic activity. In this work, Cu-doped CMF powders were synthesized by glycine nitrate combustion process (GNC). The structure, microstructure, conductivity, coefficient of thermal expansion properties were investigated. Cu-doped CMF powders were utilized as anode material in Sr- and Mg-doped LaGaO3 (LSGM)-based electrolyte-supported solid oxide fuel cell for power performance test. The cell with structure of (Cu-doped CMF) | LSGM | LSCF was operated from 600 to 800 °C with humidified H2 as a fuel and ambient air as oxidant to evaluate the electrochemical properties. keywords：Ce0.6Mn0.3Fe0.1O2, glycine nitrate combustion process, Sr- and Mg-doped LaGaO3

Applications of the Glycine Nitrate Combustion Method for Powder Synthesis on the LSGM-based Electrolyte-Supported Solid Oxide Fuel Cells

Solid oxide fuel cells (SOFCs) are recognized as environmentally friendly, highly efficient devices, and alternatives to conventional energy conversion systems. Typical material design used is the YSZ-based cell consisted of NiO-YSZ and LSM as anode and cathode, with a dense electrolyte of YSZ. When considering the use of hydrocarbon fuels, carbon deposition has been observed as major failure issue in electrodes. Also the homogeneity of the electrolyte is essential for the gas-tightness after sintering process. In this article, we propose an innovative chemical reactor with powder collection system and its application to glycine-nitrate combustion process to produce precision ceramic powder in nano scale, not only generates precision ceramic powder of specific chemical composition in a mass-production scale, but also the system has the primary features of withstanding the instant high-temperature flare and pressure during powder formation reaction. Electrodes/electrolyte powders, SmBa0.5Sr0.5Co2O5+δ (SBSC), Ce0.6Mn0.3Fe0.1O2 (CMF), and La0.9Sr0.1Ga0.8Mg0.2O3- d (LSGM), have been synthesized and characterized for the crystallinity, microstructure, conductivity, coefficient of thermal expansion properties were studied. The material application to form an SOFC has been executed and cell performances are investigated as well.

Electrochemically modified, robust solid oxide fuel cell anode for direct-hydrocarbon utilization

A main advantage of solid oxide fuel cells (SOFCs) operating at a high temperature (>650°C) is the flexibility of the fuel they use, specifically as they offer the possibility to utilize methane (natural gas). Unfortunately, however, the state-of-the-art SOFC anodes, composed of a nickel and an anionically conducting oxide such as yttria-stabilized zirconia (YSZ), are associated with Ni-catalyzed carbon deposition and the ensuing degradation of the anode performance. Here, we address these issues through the application of a simple, scalable, cost-effective ceramic coating method known as cathodic electrochemical deposition (CELD). Samaria-doped CeO2 (SDC) was chosen as the coating material due to its high chemical stability against carbon formation, high electronic and ionic conductivities, and favorable electrocatalytic activity toward fuel oxidation reaction. Nanostructured SDC layers with a high specific surface area were successfully coated onto Ni surfaces via CELD. The physical and chemical attributes of each coating were characterized by a range of analysis tools, in this case SEM, TEM, XRD, EDS, ICP-MS and Raman spectroscopy. An analysis of the AC impedance spectroscopy (ACIS) of Ni-patterned YSZ symmetric cells (anode|electrolyte|anode) with SDC coatings revealed significantly enhanced electrode activity toward fuel oxidation and coking stability under dry or wet methane fuel at 650°C. These results suggest that the Ni-surface modification via CELD can be a feasible solution for the direct use of hydrocarbon fuels in SOFCs.

Compressed Air as a Clean Energy Source for Vehicles

In today’s civilization the excessive use of hydrocarbon fuels in transport sector is causing serious effect on environmental damage to the extent of 77.8% due to its tail pipe emission which mainly releases: carbon dioxide,carbon mono-oxide, nitrous oxide, and other un-burnt gases contributing to green house gases. The excessive consumption of hydrocarbon fuel has also led to the danger of depletion of hydrocarbon fuel and oil wells are likely to be dried around 2047, leaving much disastrous effect like global warming, tsunami, hurricane and health hazards etc.. This paper describes the compressed air as a clean energy source that can be utilized with the help of suitable air driven engine to develop shaft work to run the light transport vehicles along with compressed air storage tank system. A novel rotary air engine has been designed and developed to produce 73-97% of its performance efficiency. Supplementing the hydrocarbon fueled vehicles with the use of compressed air for running vehicles will significantly control the emissions and enhance the energy sustainability.

Dynamics of hydrogen powered CAES based gas turbine plant using sodium alanate storage system

Typical compressed air energy storage (CAES) based gas turbine plant operates on natural gas or fuel oils as fuel for its operation. However, the use of hydro-carbon fuels will contribute to carbon emissions leading to pollution of the environment. On the other hand, the use of hydrogen as fuel for the gas turbine will eliminate the carbon emissions leading to a cleaner environment. Hydrogen can be produced using renewable energy sources like wind, solar etc. Storage of hydrogen is a bottleneck for such a system. A high capacity sodium alanate metal hydride bed is used in this study to store the hydrogen. The dynamics of the CAES based gas turbine plant operating with hydrogen fuel is presented along with discharge dynamics of the metal hydride bed. The heat required for desorbing the hydrogen from the metal hydride bed is provided partly by the hot flue gas exiting from the low pressure turbine and partly by external heating. Thus some of the heat from the flue gas is extracted. A novel multiple bed strategy is employed for efficient desorption. Each bed consists of a shell and tube, with alanate in the shell and heating fluid flowing through the helical coiled tube. Hydrogen combustor is modeled using a simplified Continuous Stirred Tank Reactor (CSTR) assumption in CANTERA. The NOx emissions in the low pressure turbine exhaust stream are presented.
