A good article by Kristina Sevastianova from our Stellae Energy Ltd. team about how CO2 can be utilised in addition to those volumes being sequestered. For collaboration or enquiries, contact us@stellaeenergy.com CO2 Utilisation Once I read on the coffee jar that “This coffee has been gently decaffeinated using CO2”. Good example of #circulareconomy and #wastemanagement. […]

A range of heat transfer systems to access heating and cooling With higher costs for energy required for heating or cooling, other options than the use of electricity or carbon based fuels are available. Shallow Geothermal Energy involves extracting heat or cooling from the relatively shallow subsurface using heat pumps. […]
For remote, power intensive Extractive or Hydrocarbon Processing Sites For remote, power intensive Extractive (Mining), Hydrocarbon Processing, or Industrial sites, sometimes there might be an opportunity to install large scale hybrid renewable energy solutions. Combining Solar PV, Wind, and perhaps Geothermal could offer a resilient energy mix, able to better […]
Geothermal Energy resources are found in tens of thousands of locations, however not all locations are conveniently located close to suitable electrical utility grids with good feed-in tariffs. One option is to use the electricity to produce some form of Green Hydrogen for road, rail, or pipeline export to market. […]
Off grid or Bad grid Standalone Power Systems (SPS) Off grid or bad grid Standalone Power Systems can utilise hybrid Solar PV and Hydrogen power solutions to provide economic, environmentally sustainable clean Renewable Energy systems. In some locations, the Solar PV can be supplemented by Wind Turbines. For locations with […]
Microgrids helping to mitigate Energy Poverty with Renewable Energies With the challenges of remote locations, either bad grid or off grid, the Standalone Power System concept is a potentially technically and commercially attractive solution. Energy Poverty of many of these locations in the Developing World is hindering the achievement of […]
Potential for Geothermal, CCS, EOR/EGR, and Energy Storage End of life, depleted hydrocarbon, porous formations, either sedimentary or naturally fractured systems, are valuable assets with existing data and infrastructure potentially able to be repurposed for hybrid redevelopments. Additional value is able to be investigated and captured with potential combinations of […]
Another type of reservoir potentially able to be used to capture Geothermal Energy is naturally fractured geological systems. Significantly recognised for potential hydrocarbon production over the past decade, some of these reservoirs may have good effective permeability to be repurposed later to facilitate the circulation of heat transfer fluids for […]
The next CCS example in SE Asia to be discussed is the BP Tangguh project in Indonesia. A giant depleted gas reservoir is planned for carbon sequestration along with Enhanced Gas Recovery (EGR). Significant CO2 emissions from the LNG facilities will be captured and injected into the nearby Vorwata reservoir.
Some very good projects are being developed in South East Asia involving high CO2 gas reservoirs and the use of Carbon Capture and Storage of these potential emissions in nearby depleted gas reservoirs. The first example is Repsol’s Sakakemang project in Sumatra Indonesia.
In the right circumstances, CCS and EOR can be linked to sequester significant amounts of CO2 (up to ~100mmscfd / 2 MTA) and extract additional amounts of residual oil (up to ~50mmbo in some places). Finding the right large low BTU reservoir and then locating a large residual oil reservoir […]
Another example of where experience with utilising CO2 injection to facilitate Enhanced Oil Recovery has also helped advance confidence in carbon sequestration technologies and storage integrity monitoring. These combined CCS and EOR solutions continue to scale up with very significant similar but much larger projects being investigated internationally.
