As early as 2006, LiquidSOL was committed to reducing greenhouse gases. Traditional energy generation using fossil fuels such as coal or oil fuels climate change. LiquidSOL countered this with combined heat and power generation using renewable raw materials instead of fossil fuels. Diesel engines specially modified for the use of vegetable oil produced electric power as well as heat.
Even then, the focus was on using these plants in agriculture.
The average plant size was designed for a continuous output of around 300 kWel. This was sufficient to supply even larger farms with electricity. In the winter months, the heat generated covered the heating requirements of residential and farm buildings. With an absorption chiller (ACM) using heat for cooling, it was possible to cover the typical cooling requirements of a farm for milk, for example.
In the interests of maximum energy efficiency, LiquidSOL not only optimized diesel engines for use with vegetable oil, the consumption of these engines was also specifically optimized for the application. As a result, average consumption fell by around 15%. This was accompanied by a reduction in combustion residues. Moreover, the vegetable oil used as fuel ensured CO2-neutral operation of the plants.
In addition to the development, construction and operation of these pioneering plants, LiquidSOL provided know-how for the reduction of fuel consumption at an early stage in its corporate history. A large number of plants throughout Germany were thus significantly reduced in consumption.
