Henri HornThere are technical options to extend solar energy usage for heat delivery during winter months.
#Heliostorage uses borehole thermal heat storage technology to inject heat into shallow 50m soil and recover months later, similar to the #DrakeLanding site in Canada.

Borehole Thermal Energy Storage
Borehole Thermal Energy Storage Borehole Thermal Energy Storage Large Scale Thermal Energy Storage The Heliostorage borehole thermal energy storage solution provides large-scale underground energy storage that enables the long term, energy efficient and eco-friendly storage of heat. One of the biggest challenges with any sensible heat storage solution is overcoming losses. Through multiple iterations and […]
Some companies already offer promising 'low-tech' energy solutions that were not so attractive when energy was cheap and abundant:
#Heliostorage uses #BoreholeThermalEnergyStorage to make #SolarHeat available in winter. Similar to #DrakeLanding in 🇨🇦

#SavoSolar has built many large #PitThermalEnergyStorage systems in Central Europe, but not yet Finland.

We should quickly ramp up such technologies.
How It Works
How it Works Seasonal Thermal Energy Storage is the most energy efficient solution for the heating of buildings. It can be deployed from small to large scale and allows the heat production to be located close to where it is needed. How Does Seasonal Thermal Energy Storage Work? The cycle begins in spring when the […]
