Calculations for CO2 emissions, sequestration capacities and solar energy
1. Using black coal and the newest coal firing technology, 1MWhr of power generates about 0.7 tonnes of C02. 80 MW of power x 24 hours in a day = 80 x 24 hrs x 0.7t = 1,344 tonnes of CO2 per day. ZeroGen say the first gasfield can sequester 200,000 tonnes. 200,000 tonnes / 1,344 tonne per day = 149 days.
2. 1MW (Mega watt) = 1000kW (kilo watt). 1000kW x 24 hours = 24,000 kWhr, and a kWhr is the unit of billing for domestic power. An average home uses 10 to 30 kWhr of power a day, so 24,000 kWhr of power will power about 1,200 houses. 80MW could run a town of about 96,000 houses.
3. The Bureau of meteorology web site's solar radiation charts, says that most of Australia gets over 10 MJ (Mega Joules) of solar energy each day on every square metre. This equates to 2.8 kWhr / sqm /day. An average house has a roof of about 150 sqm, which means that the roof is hit by 420 kWhr of solar energy every day.
