"Energy transition" in iConvert
Posted: Mon Oct 29, 2018 6:25 pm
In the Netherlands there are advanced plans to say goodbye to fossil fuels for home use. That means we have to start thinking about how we can keep our house warm because that is for most Dutch people the biggest energy consumer. That is why I have extended iConvert with the category "Energy transition" with which one energy carrier can be converted to the other.
Before that, I first had to find out the calorific values of the various energy sources and convert the use into average power. The list that I made for this is attached as a PDF file "Energy transition.pdf". In order to be able to easily determine the average power of annual consumption, I have added the following items in the "Power" category: "Kwh / year" and "Megajoule / year".
For various energy carriers in the category, I have not only entered the annual consumption but also the daily consumption so that, for example, the peak power in the winter can be converted.
The screenshot shows that 1m³ Dutch natural gas per year corresponds to a power consumption of approximately 1 watt. Easy as a rule of thumb. Also a liter of petrol gives almost the same value.
As a possibility for energy storage, I have added the freezing of water. It is remarkable that a peak winter consumption of 20m³ of natural Dutch gas per day can theoretically be replaced by the heat that is extracted when freezing 2m³ of water.
Perhaps I should start digging a pond of at least 2 m³ in my garden. But then I also have to place 244m² of solar panels to thaw the ice during the day. However, it seems more practical to have a 3000 liter LPG tank buried in my garage path. With a single filling, from Belgium
, I can also replace my annual consumption of 2300m³ of gas.

As a possibility for energy storage, I have added the freezing of water. It is remarkable that a peak winter consumption of 20m³ of natural Dutch gas per day can theoretically be replaced by the heat that is extracted when freezing 2m³ of water.
Perhaps I should start digging a pond of at least 2 m³ in my garden. But then I also have to place 244m² of solar panels to thaw the ice during the day. However, it seems more practical to have a 3000 liter LPG tank buried in my garage path. With a single filling, from Belgium
, I can also replace my annual consumption of 2300m³ of gas.
