>>
>> An example:
>> A family in Denmark:
>> Gross income 100000 EUR pr year - personal income tax 40000 EUR - Left for
>> consumption 60.000 EUR pr year
>> Energyconsumption:
>> 8 MWh  ~ price 40 EUR + tax 200 EUR = 320 EUR + tax 1600 EUR
>> 2000 liter petrol ~ price ,6 EUR + tax ,7EUR = 1200EUR + tax 1400 EUR
>> 1500 m3 nat gas ~ price ,5 EUR + tax ,8 EUR = 750 EUR + tax 1200 EUR
>> Total energy bill 2270 EUR --  tax 4200 EUR.
>>
>> Thus the energy tax is close to 10 % of what this family pays in tax
>>
>> If this family converts to non taxed energysources - the tax will have to

>>
>>
>>
>> It was not easy to draw a conclusion from the presentations.
>>

>>
>> The Skive plant is using fuel at 1200 DKK/tons (162 EUR) and has an
>> availabilty of 50 % now.
>>
>> The pyroforce techmology seems to work but there where no economical numbers
>> in their presentation.
>>
>> The Stirling present investment figures of 1,4 MEUR for a 140 KWel plant and
>> present a payback times of 5,5 years if they can sell the electricity at 270
>> EUR/MWh and the heat at 45 EUR/MWh and the maintenace cost are defined at 45
>> kEUR/years.
>>
>> V?lund technology definetely works and produce electricity, heat and taroil
>> but they present no economical data.
>>
>> DONG presented their 85/15 plan which is almost financed by converting taxed
>> fuel (coal) into non taxed fuel (biomass) - but rumours say that the tax
>> issue most be solved first (who is going to pay for the hospitals if the
>> energy tax on fossils are not payed?)
>>
>>
>>
>> For our own 3 stage gasification technology we are expecting a total
>> electricity production  cost of 300-400 EUR/MWh with a fuel price of  5
>> EUR/GJ and no income for heat for a 1 MWel gasifier in generation 3. We base
>> this number on approx 12000 hours operation wtih two 50 kWel gasifier.
