I. what is the energy content (GJ/ha) of willow at 55% moisture content, if it has a calorific value of 7MJ/kg and a yield of 22 tonnes/ha at 55% M.C?
II. if one tonne (1145 litres) equals 43GJ, what is the oil equivalent in litres of the willow per hectare?
III. if edenderry power station has an excess CO2 how many tonnes of willow at 55% M.C would be needed to clear the excess CO2? peat has a calorific value of 8GJ/tonne and yields 0.856 tonnes of CO2 per tonne burned
IV. what is the energy content of 10 ha of miscanthus at 20% M.C if the net calorific value is 13.7 MJ/kg at a yield of 12.5 tonne/ha?
