Wave energy resources: Wave climate and exploitation
Portilla, Jesus; Sosa, Jeison; Cavaleri, Luigi - In: Renewable Energy 57 (2013) C, pp. 594-605
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...

Hydrogen–ethanol blending as an alternative fuel of spark ignition engines
Al-Baghdadi, M.A.S. - In: Renewable Energy 28 (2003) 9, pp. 1471-1478
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...

An analytical formula for the capacity credit of wind power
Voorspools, Kris R.; D'haeseleer, William D. - In: Renewable Energy 31 (2006) 1, pp. 45-54
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...
