To limit the warming of the planet to no more than a 2°C increase, models show that net-zero release of anthropomorphic CO2 must be achieved by the middle of the century. For the foreseeable future, the majority of the world's energy will still be provided by fossil fuels, so other methods, besides expanding the contribution of renewable energy, are needed in order to achieve this goal. According to the Intergovernmental Panel on Climate Change (IPCC), carbon capture and sequestration (CCS) is one such method, without which the cost to achieve the 2°C target would more than double. To achieve this climate goal, CCS efforts must increase by approximately 100-fold from current levels within the next 20 years. Geophysical simulations on suitable geologic models will provide an important tool to streamline and accelerate the vast expansion of geophysical site characterization and long-term monitoring tasks required for industrial-scale CCS to succeed.

Net zero requires an accelerated transition from fossil fuels to renewables. Carbon capture and utilization (CCU) can be an effective intermediate solution for the decarbonization of fossil fuels. However, many research works contain renewables in the design of CCU systems, which may mislead stakeholders regarding the hotspots of CCU systems. In this work we build a model of a CCU system with no renewables involved, and evaluate its greenhouse (GHG) emissions based on the life cycle assessment with a cradle-to-gate boundary. To pursue the best system performance, an optimization framework is established to digitalize and optimize the CCU system regarding GHG emissions reduction. The optimized CCU can reduce GHG emissions by 13% compared with the conventional process. Heating is identified as the most significant contributor to GHG emissions, accounting for 60%. Electrifying heating fully by low-carbon electricity can further reduce GHG emissions by 47%, but such extreme conditions will significantly sacrifice the economic benefit. By contrast, the multi-objective optimization can show how the decisions can affect the balance between GHG emissions and profit. Further, this work discusses the dual effect of carbon pricing on the CCU system – raising the cost of raw materials and utilities, but also gaining credits when emissions are reduced in producing valued products.

The Cost

The foreseeable energy future will be driven by economics of known technologies and the desire to reduce CO2 emissions to the atmosphere. Renewable energy options are compared with each other and with the use of fossil fuels with carbon capture and sequestration (CCS). Economic analysis is used to determine the best of several alternatives. One can disagree on the detailed costs, including externalities such as climate change and air and water pollution. But the differences in capital and operating costs between known technologies are so significant that one can draw clear conclusions. Results show that renewable energy cannot compete with fossil fuels on a cost basis alone because energy is intrinsic to the molecule, except for hydroelectricity. However, fossil fuels are implicated in climate change. Using renewable energy exclusively, including transportation and electricity needs, could reduce the standard of living in the United States by 43% to 62%, which would correspond to the level in about 1970. If capture and sequester of CO2 are implemented, the cost of using fossil fuels will increase, but they beat renewable energy handily as an economic way to produce clean energy.

Significance LNG is cleaner than most fossil fuels but still incompatible with net zero emissions. India, China and other Asian economies see LNG imports as a ready and economically viable means of displacing coal and oil use. Natural gas and then LNG demand will eventually peak as the energy transition accelerates over the next 20 years. Impacts LNG market growth will embed fossil fuel use and infrastructure in developing economies’ energy mixes. Recent market volatility and record spot LNG prices may reverse the trend of greater reliance on spot transactions than long-term contracts. Although the greenhouse gas (GHG) benefits of LNG use in transport are far from clear, it will gain market share in the next few years. LNG project developers will seek to cut GHG emissions from their projects to prolong LNG's attractiveness in the energy transition.

The movements for any type of electric vehicle (EV) can be powered by wheels or driven by rotary motors. EVs derive their power from various sources, including fossil fuels. In the long term, reducing the cost of electrically powered vehicles (EDV) is seen as an essential ingredient to increase consumer acceptance. In addition, it aims to reduce the weight and volume of EDV. Moreover, the focus is on improving the performance, efficiency, and reliability of the EDV. The development of innovative modules is important when the acceleration of production and marketing needs to be improved. Consumers are looking for the production and transmission of electrical energy. This contributes to a greener environment. One of the most important parts of an EV is its battery. A proposed model presented in this chapter considers several parameters: solar radiation (PV panels), EV backup battery, and main charger. The model allows energy storage to be developed efficiently.

Efficient Recovery

It is likely that the future availability of energy from fossil fuels, such as natural gas, will be influenced by how efficiently the associated CO2 emissions can be mitigated using carbon capture and sequestration (CCS). In turn, understanding how CCS affects the efficient recovery of energy from fossil fuel reserves in different parts of the world requires data on how the performance of each part of a particular CCS scheme is affected by both technology specific parameters and location specific parameters, such as ambient temperature. This paper presents a study into how the energy consumption of an important element of all CCS schemes, the CO2 compression process, varies with compressor design, CO2 pipeline pressure, and cooling temperature. Post-combustion, pre-combustion, and oxyfuel capture scenarios are each considered. A range of optimization algorithms are used to ensure a consistent approach to optimization. The results show that energy consumption is minimized by compressor designs with multiple impellers per stage and carefully optimized stage pressure ratios. The results also form a performance map illustrating the energy consumption for CO2 compression processes that can be used in further study work and, in particular, CCS system models developed to study performance variation with ambient temperature.

AbstractFacing intense price competition and societal pressures, health care provider organizations have focused increasingly on the cost-effectiveness of medical services. In instances when there is insufficient evidence that a more expensive treatment course generates improved outcomes, the lower cost option is often encouraged. Yet, with resource utilization still determined principally by individual physicians, large practice variations often persist. This paper reviews the literature and explores the impact of sharing cost information on physicians' practice patterns utilizing management theory concepts. More research should be conducted to determine long-term benefits of educational interventions, physicians' fundamental views on the relationship between cost and quality and its effect on their responsiveness to cost information, and the role of leadership in changing clinical behavior.

Abstract One of the way to reduce the greenhouses gases emissions generated by the fossil fuels combustion consists in the Carbon Capture, Transport and Storage (CCS) technologies utilization. The integration of CCS technologies in the coal fired power plants increases the cost of the energy generation. The CCS technology could be a feasible solution in the case of a high value of a CO2 certificate but for the present value an optimization of the CCS technology integration in the power plants is expected. However, for reducing the cost of the energy generated in the case of CCS integration in the power plants, a parametrical study optimization of the CO2 capture process is required. In this study, the chemical absorption process was used and the monoethanolamine with 30 wt. %. The objective of this paper is to analyze the effects of the package type used in the absorption column on the size of the equipment used and, on the energy cost of the power plant with CO2 capture process consequently. The packages types analyzed in this paper are metal Pall rings with different sizes and the rings are made of different metals: aluminum, nickel, cooper, and brass. In the case of metal Pall rings, the utilization of different material has an impact on the absorption column weight. Also, Pall rings made of plastics (polypropylene and polyethylene) were analyzed. The comparative assessment was achieved for a coal fired power plant with an installed power of 100 MW and considering the CO2 capture process efficiency of 90 %.
