From previous research and monitoring of agricultural biogas plants it is known that there are various possibilities and needs for improving their efficiency. However, a reliable methodological approach for this purpose was missing. Therefore, the objective of this research was to develop a...

Combustion is often used in the industry to produce required energy. Due to the increasing need of minimizing energy loss or pollution of combustors, keeping good performance of combustion control is highly desired. To achieve tight combustion control is not straightforward, because most of the...

This paper builds a system dynamics model to simulate the effect of China’s strategic petroleum reserve (SPR) on stabilizing the domestic oil price. By setting the sensitivity of the market to the domestic oil price and the increase in international oil price, this paper discusses three...

Malaysia has abundant potentials of renewable energy resources mainly because of its rich agriculture that makes high potential in bio-power and its tropical climate, which provides sufficient sunlight for utilization of solar systems. Feed in Tariff mechanism has been applied since 2011 in...

The integration of renewable energy sources into existing energy systems has emerged as pivotal in the context of sustainable energy planning. However, despite their appeal, the diffusion rate of eco-innovative technologies in the energy sector varies considerably among countries, mainly due to...

A novel Air Resource Co-benefits model was developed to estimate the social benefits of a Sustainable Energy Policy, involving both renewable energy (RE) and energy efficiency improvements (EEI). The costs and benefits of the policy during 2010–2030 were quantified. A system dynamics model was...

Since ethanol is considered an essential additive for biofuel production, there may be the opportunity to employ it as such in Mexico. However, an analysis of the ethanol supply chain should be performed first. Therefore, in order to analyze the main variables of the ethanol supply chain, as...

To achieve national CO2 emission reduction targets, the Taiwanese government is planning to adopt policies, such as feed-in tariffs (FITs) and capital subsidies, in order to attract the public as well as companies to invest in and use solar photovoltaic (PV) systems. However, a huge budget is...

We discuss the role of diversification on dependency and security of energy supply. A system dynamics model with especial focus on the role of renewable energy resources (as a portfolio) on Finland’s energy dependency is developed. The purpose is also to cover a part of research gap exists in...

This paper develops a real-time automotive air propulsion system for light-duty vehicles. This system consists of a high-pressure air tank, an electric-controlled throttle valve, and a vane-type air motor. The isentropic-nozzle element and control volume concepts were introduced with their...
