As discussed last week in last week’s posts on the Energy Transition, increased Electrification is required to support Decarbonisation. Not discussed very much in the press are Electrical Grid Challenges, but some articles are beginning to appear as writers get more informed. Without addressing these challenges quicker and without orders […]

A heat transfer systems to access more cost effective heating and cooling Temperature extremes and high energy prices are causing economic and health risks in multiple countries including India. Many people either do not have access to air conditioning or they cannot afford the cost of electricity required. One potential […]
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. […]
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 […]
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 […]
David Hartell MD & CEO Stellae Energy always been a voice of reason in the energy debate. Stellae Energy Ltd. supports Africa in its efforts to secure indigenous energy resources. Until Africa develops (and has the financial means to do so) #renewablesenergy resources such as #Geothermal, #biomass, #solarpower and #windenergy […]
A number of times various people have said CCS does not work and used the example of Chevron’s Gorgon Project to justify their views. This is uninformed and incorrect – the CCS element of the project worked with carbon capture in the process trains and transportation through pipelines and wells […]
A good informative article by Stellae Energy’s Head of Subsurface David Pickering is reposted here. https://lnkd.in/gKYwVQmt O&G folks aren’t necessarily very familiar with SUPERCRITICAL FLUIDS, but they are an important concept for those working in geothermal / CCS and something with which they need to become comfortable. I have drawn a couple […]
Another type of potential CCS location is depleted oil & gas reservoirs. In these kinds of locations, there would typically be much more data available initially for the technical assessment of the storage capability and any potential integrity issues. Existing well records, production data, and geophysical surveys would be useful […]
The first in a series of posts about successful CCS projects. Deep Saline Aquifers are considered good potential for CCS projects, but substantial subsurface geophysical and geological work is necessary to demonstrate this suitability and long term integrity. One attraction is the fact that these types of aquifers are widespread […]
The East African Rift System is a well known source of Geothermal Energy in Africa, but there is potential for low to medium enthalpy heat resources in more than 25# African countries associated with intrusive plutonic rock formations. Often these locations have been the site of shallow mineral exploration and […]
