Welcome to Geoviridien – An Alternative Energy Technology Company. Over the next few posts, we hope to focus a spotlight on important and innovative technologies and developments in the Energy Transition. The name “Geoviridien” originated from three words: “Geo”=Earth, “Viridi”=Green, and “En”=Energy or “Earth’s Green Energy”. Individuals and organisations in […]

With intermittent renewable energies like Solar PV and Wind Turbines, it is necessary to consider energy storage to cover the times when the wind does not blow or the Sun does not shine. Short duration energy storage systems cover outages up to 4 hours and provide substantial grid stability. These […]
The ocean contains a lot of energy in waves and tidal streams. Intermittency may be reduced with persistent energy driven by winds, the Sun, gravity, the Earth’s rotation, density, and temperature. Analogous to wind turbines in the air, there are a range of technical solutions in the ocean to similarly […]
Literally beneath our feet is an incredible source of heat energy called Geothermal Energy. Over 99% of the Earth is over 100degC. Within reasonable well drilling depths (down to~5000m) it is possible to find locations with geothermal temperature gradients over 35-40 degC/km. Geothermal heat comes from (1) volcanic/magmatic sources along […]
Another popular renewable energy source has been Wind Turbines. Large onshore and offshore wind farms have been scaled up to significant energy levels. Unit costs have dropped over 90% in the past decade making this particularly attractive. •Wind turbines from tens of kilowatts up to 20 megawatts are being used […]
One of the most popular renewable energies is Solar PV with tremendous scale up of this technology across residential and commercial locations, industrial facilities, and large scale solar farms. •Unit costs have dropped over 90% in the past decade making this particularly attractive. But Solar PV energy is intermittent – […]
Carbon based fuels are a major source of carbon emissions whether for power generation or transportation. There are other sources of GHG emissions including agriculture and land clearance. Capturing carbon emissions at source is an obvious target since it is relatively easy to capture more concentrated local emissions. Utilising these […]
The Energy Transition involves a series of steps that many companies are making to improve their performance: Improve energy efficiency; Reduce Greenhouse Gas emissions and waste; Implement Carbon Capture, Utilisation, and Storage; Increase the use of Renewable Energy; The Circular Economy is another imperative where companies are working to avoid […]
Another concept for energy companies to consider is OTEC. Using familiar deepwater production facility technologies, Binary ORC power generation (used in waste heat and geothermal energy developments), and significant cost reductions over the past ten years, this energy solution is timely to be considered. Clean, persistent renewable energy that is […]
Geothermal Energy – the old new frontier in harnessing earth’s green energy. We are happy to announce that Stellae Energy is working to identify end of life oil or gas wells to be repurposed for the generation of clean, dispatchable Geothermal Energy. The Energy Transition includes reusing existing infrastructure as […]
