One of the key technologies identified by the World Economic Forum in the future of energy systems is Thermal Energy Storage (TES). TES allows for the storage of heat energy, which can be used later to generate electricity or provide heating and cooling. This is particularly important for addressing the intermittent nature of renewable energy sources such as solar and wind. By storing excess energy generated during peak production times TES systems can release energy when demand is higher or when renewable energy production is low
For South Africa, where solar energy potential is vast, TES can play a pivotal role in stabilizing the grid and ensuring a reliable supply of energy during periods when the sun isn’t shining. It also aligns with the country's need to reduce reliance on coal while addressing the intermittency challenge associated with renewable energy.

As the world grapples with the complex and ever-evolving challenges of energy security, climate change, and sustainable development, one of the most important resources for understanding our current trajectory is the Energy Institute's Statistical Review of World Energy 2024, with additional insights provided by Our World in Data. This resource offers a comprehensive analysis of global energy consumption, production, and technological trends, shedding light on the pressing need for innovation and transition to more sustainable energy systems.
In the context of South Africa, these global trends present both challenges and opportunities. South Africa is heavily reliant on coal for electricity generation, making the transition to a greener energy system crucial for reducing its carbon footprint. But transitioning from fossil fuels to renewable energy sources like solar, wind, and innovative technologies such as Thermal Energy Storage (TES) will require strategic investment and robust technological adoption.
Global Energy Trends: A Snapshot
According to the Energy Institute's Statistical Review of World Energy 2024, the global energy landscape is evolving at a rapid pace. Renewable energy sources, particularly solar and wind, continue to dominate new energy capacity additions. Despite this, fossil fuels—coal, oil, and natural gas—remain the largest contributors to global energy consumption, though their share has gradually declined as countries adopt cleaner alternatives.
Key takeaways from the 2024 report include:
• Global energy consumption continues to rise, driven primarily by developing economies in Asia.
• Coal consumption is still significant, especially in countries like India and China, but is slowly being replaced by renewable energy sources.
• Renewable energy is growing at a record pace, with solar and wind leading the charge.
• Natural gas remains a key player in the energy transition, serving as a bridge fuel in many regions.
