How can investment in geothermal solve energy shortfall?

As the demand for clean and renewable energy continues to rise in Africa, the continent faces challenges in attracting enough investment to meet these growing energy needs. CNBC Africa recently spoke with Vivian Neil, the CEO of Kalahari Energy, to discuss the potential for investment in geothermal energy to address the energy shortfall in Africa. Neil highlighted the importance of attracting private sector investment and implementing policies that encourage renewable energy development in order to achieve electrification targets and meet the Sustainable Development Goals (SDGs) by 2030. Neil emphasized the significance of geothermal energy as a reliable baseload power source, especially in regions where variable renewable energies like wind and solar may not suffice. Kalahari Energy is leading the way in geothermal energy development, with the Bwanda section of the Buengua River project showcasing the company's commitment to sustainable power generation. The project, which has already seen an investment of approximately $9 million, aims to exploit a shallow outflow geothermal system to initially generate six to seven megawatts of electricity. This marks the first stage of a larger resource exploration effort that could potentially revolutionize geothermal power in Zambia and southern Africa. One of the key technologies employed by Kalahari Energy in geothermal power generation is binary technology. This innovative approach involves using low-temperature geothermal fluids to boil a fluid with a lower boiling point, such as isobutane or refrigerant, to create steam and drive a turbine for power generation. The geothermal fluid is then re-injected back into the system, creating a closed-loop process that maximizes energy efficiency. By harnessing the potential of geothermal energy and binary technology, Kalahari Energy is poised to play a significant role in transforming Africa's energy landscape and meeting the continent's growing electricity demands. In conclusion, investment in geothermal energy represents a promising solution to Africa's energy shortfall, offering a sustainable and reliable source of power for the region. With Kalahari Energy leading the charge in geothermal exploration and development, the potential for significant growth and expansion in the renewable energy sector looks increasingly achievable. By leveraging innovative technologies like binary systems and prioritizing private sector involvement, Africa can move closer to achieving its energy goals and driving economic development through clean and renewable energy sources.
