Vortex Power Systems

An innovative technology to turn wasted heat into electricity.

Power from waste

Thermal processes are an inefficient process, but they are a part of our everyday life, from power generation to concrete manufacturing. Most of these processes are only 30 - 40% thermally efficient - which means 60 - 70% of the energy used in them is wasted.

Vortex Power Systems Limited is developing a proprietary system to convert any source of waste heat into a zero-carbon powerplant and generate electricity from the wasted energy.

Our first application is existing thermal power plants to enable them to produce the same amount of power whilst using less fuel and reducing their carbon emissions.

Globally, over 13 000 TwH of potential energy lost as wasted heat per annum. Enough to power over 3 billion households

How it works

Wasted heat from thermal processes are normally captured in their cooling circuits, that traditionally use water.

Our technology utilises this to create a controllable vortex akin to a waterspout that will be created from a difference in temperature and water vapour. The waste heat then acts as the energy source for the system.

This energy source, when combined with a source of horizontal air circulation or swirl, creates a rotating, rising column of buoyant air that produces concentrated rotating winds at the ground, like a controlled tornado. By placing a wind-turbine at the base of the vortex, we can convert the wind from the vortex into power; capturing a portion of the waste heat energy as electricity.

STEP 1.

Low-level waste heat from power generation

STEP 2.

Heated water sprayed into system

STEP 3.

Initial rotation of turbine

STEP 4.

Rising heat and rotation of air draws in air at an angle

STEP 5.

Creation of self-sustaining vortex

STEP 6.

Vortex drives power generation turbine at base

STEP 7.

Additional 7.5% electricity generation

STEP 8.

Remove heated water to halt operation

Electricity demand continues to rise and will double by 2040.

Advantages

Vortex’s system functions to create and control a vortex in the atmosphere, which creates winds to drive a power generation turbine at its base. Since the wind power in the vortex is manmade, the power generation capabilities are expected to be more consistent and not as susceptible to the unpredictability of the weather compared to a conventional wind turbine or solar facility. Waste heat from thermal power stations tends to be of “low quality” which means the temperature is too low to be useful, however Vortex believes its technology will be able to function using this low-quality heat.

  • Functions with low energy density waste heat
  • 60% of the capital cost of wind - no requirement for ‘tower’
  • Unlike solar and wind, not weather dependent
  • Replaces need for cooling tower
  • Highly scalable
