What are the potential benefits and challenges of integrating hybrid-electric propulsion systems into commercial aircraft?5 answersIntegrating hybrid-electric propulsion systems into commercial aircraft offers significant benefits and challenges. The benefits include potential energy savings ranging from 1% to 14% over conventional engines, reduced fuel consumption, and improved emissions. However, challenges arise in system integration, especially when retrofitting existing aircraft, due to complexities in space utilization, power distribution, safety, and thermal management. Implementing hybrid-electric systems requires bridging the gap between aircraft and subsystem levels, necessitating advanced integration tools for efficient conceptual design. Additionally, the development of new energy storage methods like battery-superconductor hybrids aims to enhance performance metrics such as weight reduction and fuel efficiency. Overcoming these challenges while leveraging the benefits is crucial for the successful adoption of hybrid-electric propulsion in commercial aviation.
What is the cost of balance of plant for hybrid power plants?5 answersThe cost of balance of plant for hybrid power plants has been investigated in several studies. In the HYLIFE-II concept, the impact of molten salts on the direct capital cost of the balance of plant (BOP) and the cost of electricity (COE) has been analyzed using the RUBY computer code. Another study analyzed two different architectures for a hybrid power source, comprising a polymer electrolyte membrane fuel cell and a Li-ion battery, in the Boeing Fuel Cell Demonstrator airplane. Additionally, a proposal for a hybrid plant composed of wind and photovoltaic generation with two types of storage, lithium-ion batteries and a thermal storage system, analyzed the techno-economic aspects to optimally size the plant and determine the most cost-competitive solution. These studies provide insights into the cost considerations for balance of plant in hybrid power plants.
What will be the difference for for hybrid vs Electric air taxi passengers price/km/PAX?5 answersHybrid and electric air taxis offer different advantages in terms of price per kilometer per passenger (PAX). In the case of today's technology, a full electric air taxi has advantages over a hybrid-electric road taxi, especially in cases involving low emission intensity and unfavorable driving conditions. The comparison with a referenced fully electric road vehicle is detrimental to the air taxi, but the CO2 emissions for the air taxi are still quite low. However, in the case of 2035 technology, the comparison with a fully electric road vehicle is not favorable for the air taxi. The difference in price per kilometer per passenger between hybrid and electric air taxis is not explicitly mentioned in the abstracts provided.
Is pricne of fossil fuels expensive ?5 answersFossil fuel prices vary depending on factors such as location and fuel type. The economic value of health impacts associated with fossil fuel electricity in the United States ranges from $0.005-$0.013/kWh in California to $0.41-$1.01/kWh in Maryland. In Iran, the price policy for fossil fuel consumption suggests increasing prices gradually within 2018-2030, with diesel, gasoline, and liquefied petroleum gas prices expected to increase by certain percentages. Implementing extended producer responsibility (EPR) for fossil fuels can deconflict energy security and climate policy at an affordable cost. However, the price elasticity of fossil fuel demand is lower than one and inelastic, making price policy ineffective in reducing consumption. Instead, energy efficiency improvement is much more effective in reducing fossil fuel consumption, saving significant amounts of fuel, expenditure, CO2 emissions, and improving sustainable development. Therefore, while fossil fuel prices can be expensive, the effectiveness of price policies in reducing consumption varies, and energy efficiency improvement is a more impactful approach.
Why hybrid cars is a bad investment?1 answersHybrid cars may be considered a bad investment due to several factors. Firstly, the high initial cost of hybrid cars compared to conventional cars makes it difficult to achieve a payback, especially in countries without privileges for hybrid car acquisition or operation. Additionally, the reduction in fuel costs with hybrid cars is only around 20%, which further hinders the payback period. Furthermore, there is a low potential for electric cars but a significant latent demand for hybrid cars, indicating a preference for hybrid technology over fully electric vehicles. This suggests that the market for hybrid cars may not be as strong as initially anticipated. Overall, the combination of high initial costs, limited fuel savings, and potential market limitations make hybrid cars a less favorable investment option.
