Joubert Konsult

Joubert Konsult is focused on providing appropriate energy storage solutions into Africa. These include proven Thermal Energy Storage (TES) and Flow Battery technologies, while also exploring other storage technologies such as high energy density solutions for future EV charging stations. We are available to work with potential clients to explore how our storage systems may be integrated into an optimal and cost-effective solution to suit their needs.

Energy Storage in Africa

    Appropriate energy storage for:

  • Micro/Mini-grid
  • Off-grid, including hybrid applications
  • Medium to large (MWh) storage
  • Balancing of grids
  • Harvesting and re-use of wasted heat energy

Africa's Energy Challenge

More than 60% of Africa’s people do not have access to electricity, which is deemed essential for the education and connectivity of all people in order to advance in terms of literacy and economic development.

Part of the problem is that existing electricity grids are mostly outdated and too expensive to extend to rural communities.

The popular solution is found in micro-grids with solar and wind energy plus storage to provide for periods when solar and wind do not generate electricity.

Even in more advanced economies, national grids have challenges to balance the load, voltage and frequency in the presence of solar and wind energy generation, which are both inconsistent. Electricity storage is required to stabilise the grid.

Thermal Energy Storage

Joubert Konsult offers a Thermal Energy Storage solution from a European vendor, which provides a low technology solution with the following features:

  • Upward scalability from >2 MWh per module
  • Each module contained in a stackable 12m container-sized package
  • Applicable to utility-sized grid solutions to balance the load
  • Capable of capturing and storing heat energy lost to the atmosphere – may be re-used as heat energy or electricity through steam.

Thermal Energy Storage Applications

  • Grid balancing
  • Boiler optimisation
  • Any production process where heat energy is lost to the atmosphere
  • Mining, metal, glass, ceramic and cement processing
  • Saving of grid peak time electricity costs

Flow Battery Storage

  • US technology with global lowest Levelised Cost of Storage (LCOS)
  • Zero to full rated power within 0,4ms
  • pH similar to soda and wine, no toxic materials
  • Inherently safe, no fire risk
  • Environmentally friendly
  • 100% recyclable
  • No materials degradation
  • Designed for 25-year project life with no performance degradation
  • 50kW and 100kW stackable modules available in 12m containers – fully scalable
