About GREAT ENRG Inc.

Great ENRG is a technology company looking to reshape the electric vehicle (EV) market and the automotive industry. Great ENRG’s initial product, the Grayson Range Extender (GRE), addresses one of the challenges to rapid EV adoption.

The EV market is experiencing enormous growth driven by such factors as technological advances and government policies to address climate change. The global market is projected to grow to $2.5 Trillion by 2027. One of the challenges facing increased EV adoption is “Range Anxiety”, a driver’s fear of having enough charge to cover a long distance.

Many companies are working to address Range Anxiety with a Range Extender, a small auxiliary unit (typically a small internal combustion engine or fuel cell) that charges an EV’s battery. The GRE offers advantages over other range extenders currently in the market. It will double the range of any EV; it doesn’t rely on fossil fuels as it’s energy source, but rather the vehicle’s motion making it a clean technology; and it is manufactured from readily available materials, so it doesn’t require critical materials where access and availability are a concern.

Electric Vehicle Market

  • Electric Vehicle (EV) market has grown rapidly over the past decade driven by an increase in demand for fuel-efficient, high-performance, and low-emission vehicles along with stringent government rules and regulations to reduce transportation’s impact on climate change.

  • Global automakers are planning to spend more than half a trillion dollars on electric vehicles and batteries through 2030.

  • The global EV market is projected to grow to $2.5 Trillion by 2027

  • The International Energy Agency (IEA) projects the total number of EV’s on the road to be over 143 Million by 2030.

  • Despite the enormous growth there are still some challenges to EV adoption:

    • Lack of fast-charging infrastructure

    • High cost

    • “Range Anxiety” is the driver’s fear of having enough charge to cover a long distance.

  • To address “Range Anxiety” one of the solutions is add a Range Extender

EV Range Extender

  • An EV range extender is an auxiliary power unit equipped in EVs that extends the vehicle’s range by driving an electric generator that charges the vehicle’s battery. Range Extenders generally fall into several categories:

    • Internal Combustion Engine (ICE) Range Extender

    • Fuel Cell Range Extender

    • Micro Gas Turbine Range Extender

    • All Others

  • There are various players in the range extender market including some of the major automobile manufacturers:

    • BMW for example sells the BMW i3, an EV with a battery range of 80-100 miles. Their Range Extender is a small 2-cylinder gasoline engine that is only used to charge the batteries. With the Range Extender you can travel 160 to 180 miles.

Grayson Range Extender (GRE)

  • The Grayson Range Extender (GRE) will be revolutionary compared to other range extenders in the market

  • The GRE will double the range of any EV

  • Unlike other range extenders which still rely on fossil fuels, the GRE doesn’t require fossil fuels

  • The GRE can be manufactured from readily available materials and isn’t dependent upon critical minerals where access and availability are concerns

  • The GRE is a kinetic energy recovery system that leverages the motion of the vehicle to recharge the battery

  • About the size of two car batteries and half the weight the GRE will have minimal impact on an EV platform
