Wolmaransstad Survey Solutions
Technology-led
innovation
Dedicated to the innovation of pumped storage in South Africa and beyond.
The Project
A potential energy behemoth that can solve South Africa’s energy crisis.
Our long term cornerstone project is ambitious, unprecedented and large enough to provide 968GWh per day to the SA base load
The research
Mapping a path to renewables baseload via:
Machine learning
Wind resource database and visualization
Solar resource tools from landsat vs ground data
Developing a machine-learned relief analysis tool
Our client-inspired vision of creating a machine learned scanning tool and coastal pumped storage mechanism that can be rolled out over coastlines anywhere in the world, could be a significant contribution to combatting climate change.
Wind resource database and visualisation
Wind power is becoming one of the most important power sources in the power grid. At present, China’s accumulated wind power capacity is 188 GW, and the total installed capacity has leapt to first in the world.
Solar resource tools from landsat vs ground data
We have different models to calculate the direct solar radiation from ground and satellite data that can be used for solar radiation measurement. In this report we have compared the different tools from ground data and LandSat.
Investigating solutions to mitigate risk to animal life due to sea water ingress
Marine life can have a disastrous effect on pumped storage machinery. Specific issues which are identified include reduction in recreational fishing, swimming areas, noise and visual pollution.
The modelling pressure on concrete dam walls project
Concrete dam walls are made up of concrete and steel reinforcements. They face pressure and stresses of different types due to water pressure, weight of dam, waves and ice pressure and many other factors. This creates stability issues in the dam.
Comparison of Concrete Gravity Dams vs Earth Walls
Gravity dams are solid concrete structures that maintain their stability against design loads from the geometric shape, mass and strength of the concrete.
About
Wolmaransstad Survey Solutions (Pty) Ltd’s mission is to enable pumped hydroelectric storage to become the dominant form of utility-scale energy storage the world over.
In an innovative twist, we plan to incorporate large scale solar and wind energy to further capitalise on Southern Africa’s energy mix potential.
The key difference between our approach and traditional pumped storage is the use of sea water close to desert coastline when wind speeds are greatest and solar irradiation is at its highest.
PHES
It is often assumed that to mitigate the worst effects of climate change we need an energy revolution incorporating a raft of new ideas.
