In this paper, we develop a multi-factor real options model for a two-stage investment problem where a coal-fired power plant is later retrofitted with carbon capture and storage (CCS). A capture-ready power plant with lower retrofit costs is compared with a conventional one and higher CCS...

Thermophotovoltaic systems convert the radiant energy produced by fuel combustion directly into electricity. Such systems can potentially attain high overall conversion efficiencies. Because they may use renewable as well as fossil fuels, they permit a smooth pathway for an environmentally...

Theoretical analysis of a solar energy-powered Rankine thermodynamic cycle utilizing an innovative new concept, which uses supercritical carbon dioxide as a working fluid, is presented. In this system, a truly ‘natural’ working fluid, carbon dioxide, is utilized to generate firstly...

Using solar energy to produce fresh water and electricity simultaneously is a prospective way to solve the problems combining fresh water shortage, energy crisis and farm land degradation in Northern Victoria. This paper records the process of calculating the performance of the nozzle applying...

In identifying the most convenient zones for harvesting wave energy, it is natural to be attracted by the areas where we find the highest mean energy values. The obvious examples are the storm belts. A more careful analysis reveals that for practical use other factors need to be taken into...

China is facing a number of energy-related challenges such as shortage of electricity supply and environmental pollution. The Government recognized the important role the renewable energy plays in the power generation structure. As a result, a series of supporting policies, laws and regulations...

The performance and pollutant emission of a four-stroke spark ignition engine using hydrogen–ethanol blends as fuel have been studied. The tests were performed using 2, 4, 6, 8, 10 and 12 mass% hydrogen–ethanol blends. Gasoline fuel was used as a basis for comparison. The effect of using...

The capacity credit of wind power expresses how much ‘conventional’ power can be avoided or replaced by wind power. From data available in the literature, we have designed an analytical formula for the capacity credit based on the penetration level of the wind power in the power system, the...

CO2 emissions of the electricity supply sector in China account for about half of the total volume in the country. Thus, reducing CO2 emissions in China’s electricity supply sector will contribute significantly to the efforts of greenhouse gas (GHG) control in the country and the rest of the...

An effective pyrogas cleaning system is necessary for downstream application of biomass pyrolysis technology for power generation. Particularly, tar must be lowered to a satisfying level in order to avoid the problem of tar blockage for preventing damage to the engine and to prolong the engine...
