The British Eden Project, a special greenhouse complex for nature and education, will have a geothermal power plant.
The plant will generate 4 megawatts green electricity and heat to the park and 4,000 households. Read More
A bag full of water, situated in the crawl space of your house holds you warm for three weeks during the dark winter season. This is what we all want, isn’t it?
The advantages of the Solar Freezer:
Heat recovering Industry system.
Paper factorySappi can not use the heat which is produced during the proces, itself.
Therefore the waste heat is sent to the power company and ‘recycled’ to produce heat and cold for homes and businesses in the city of Maastricht. Read More
The Technical University of Delft want the campus to be energy neutral by 2020. Part of this metamorphosis involves a new smart heat grid.
TU Delft is converting the existing heating system into a smart heat grid that provides heat at various temperature levels from various conventional and renewable heat sources.
The Dutch startup Ecovat is making the energy supply in the built environment sustainable, by creating a large thermal storage tank that is able to store high temperature heat (to around 90 degrees C) over a longer period (> 6 months) with a loss of energy in this period of less than 10%.
Solar heating in combination with a ground source heat pump is cost-effective for the on-site heating of buildings according to the VTT technical research centre of Finland. (report)
Recover heat from the sewer. The technique is not new, but was hardly used in the Netherlands.
Now the efficiency of the technique increases, a breakthrough is coming.
In industry, lots of hot water is used for cleaning. Hot water of 60 to 80 ° C is very common. During the industrial process a lot of heat flows directly with the wastewater into the sewer.
What a waste of energy! With Regain heat exchangers, heat can be recovered from wastewater. Read More
In several regions in Europe, waste water is recycled with renewable energy as a result.
The energy output of blue engines can be increased by a factor of order 2 if warm (waste-heated) fresh water is mixed with cold sea water.
Moreover, the underlying physics can also be used to optimize the reverse process of capacitive desalination of water. Read More
