Electric Bus Could Charge Itself At Every Stop

Electric Bus Could Charge Itself At Every Stop | Sustain Our Earth | Scoop.it

Utah State University has demonstrated a first-of-its-kind electric bus and inductive charging system. This technology could be very useful for bus stops, as the vehicles stick to planned routes and could recharge every time they pass through a stop via a pad in the ground.

 

The Aggie Bus benefits from a high-power, high-efficiency wireless power transfer system capable of transferring enough energy to quickly charge an electric vehicle. It has demonstrated 90% electrical transfer efficiency of five kilowatts over an air gap of 10 inches.

How can microgrids enable us to optimize the deployment of distributed energy resources

How can microgrids enable us to optimize the deployment of distributed energy resources | Sustain Our Earth | Scoop.it

There are a number of benefits that can be derived from a well planned, implemented, and operated microgrid. Some of the key benefits we see in the US today include:

- Improved energy reliability and security of supply: This is especially so where energy is mission critical to the services being provided (i.e., health care, military bases, etc.).
- Net excess energy revenues and efficiencies: Such benefits support funding of new grid investments; this becomes a sustainable master energy plan, and in some cases is self-funded.
- Ability to self optimize assets with full self control of energy operations: This exists in cases where the microgrid operator has both the supply and demand control and responsibility.
- Deferral of infrastructure investments to better match a visible and controllable load profile: The ability to shift the peak and lower the grid imported power through savings and self generation can avoid the need for larger contracts and/or delay the building of new supply side assets.
- Enabled emissions reductions supporting sustainability targets: Where reducing emissions and overall carbon footprint is a key strategy, effective deployment of renewable energy can be achieved with the real-time control with other assets in the microgrid.
- The support of a net zero strategy; and the Microgrid Optimization Model: This allows you to systematically plan and implement steps to achieve such a goal.
- Increased reliability and backup capability: This is supported by optimally sized storage technology.
- Management of generation variability in renewable energy sources.
