FLYWHEEL ENERGY STORAGE SYSTEM ARUBA

Porsche flywheel energy storage system
In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywh. [pdf]FAQS about Porsche flywheel energy storage system
How does Flywheel energy storage work?
Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy.
What is a flywheel & how does it work?
Flywheels with the main attributes of high energy efficiency, and high power and energy density, compete with other storage technologies in electrical energy storage applications, as well as in transportation, military services, and space satellites .
How efficient is a 500 kw/100 kWh flywheel energy storage system?
The charging and discharging efficiency of a 500 kW/100 kW·h flywheel energy storage system was measured using the electric energy measurement method. The charging and discharging cycle of the flywheel energy storage system ranged from 4000 to 6000 to 4000 r/min. In the experiment, the system's charge-discharge cycle efficiency was 83.23%.
How much power does a Porsche flywheel have?
The flywheel motor in Porsche's racer had a capacity of 0.2kWh. It could deliver 163hp (122kW) for up to six seconds, offering boost for acceleration—out of corners or for passing, depending on how/when the driver decided to apply the extra power via a steering wheel-mounted button.
Does Porsche have a flywheel?
However, Porsche eventually licensed the concept from Williams Hybrid Power and set about adapting it to endurance racing in the 911 GT3 R Hybrid. Audi, too, had a go with a flywheel in its all-conquering R18 e-tron Quattro diesel-electric prototype.
How does a Porsche flywheel motor work?
Mounted in a carbon fiber box where the passenger seat would be in a road-going 911, the flywheel motor received power from, and sent power to, an 80hp (60kW) electric motor/generator at each front wheel. The configuration allowed Porsche to incorporate torque vectoring to improve handling/traction when accelerating from corner apex out.

Aruba energy storage cooling
The island is introducing a new cooling system that uses ice storage to keep air conditioning running smoothly if there is a sudden drop in wind power, the island’s main source of renewable energy. [pdf]FAQS about Aruba energy storage cooling
Does Aruba use ice for building cooling?
Aruba's utility installed a pilot ice storage cooling system that makes ice at night when electricity costs are lower. Ice is then used the following day to cool buildings instead of traditional air conditioning. Currently, Aruba gets 15.4% of its electricity from renewable sources.
Where does Aruba get its electricity from?
Aruba currently gets 15.4% of its electricity from renewable sources. The island has sufficient renewable energy resource potential, with excellent technical potential for ocean, wind, and solar renewable energy generation.
What is the cost of electricity in Aruba?
The energy landscape of Aruba, an autonomous member of the Kingdom of the Netherlands located off the coast of Venezuela, is outlined in this profile. Aruba’s utility rates are approximately $0.28 per kilowatt-hour (kWh)\* \(below the Caribbean regional average of $0.33/kWh\).
How much energy does Aruba consume annually?
Aruba has an annual consumption of 990 gigawatt-hours (GWh). Currently, about 13% of its generation comes from a 30-MW wind project and 0.9% comes from waste-to-energy (WTE) biogas. An additional renewable capacity of 34 MW is planned or in progress. Aruba's installed generation capacity is 230 megawatts (MW) with an average load of 100 MW.
How much wind capacity does Aruba need?
Aruba's 30-MW wind project at Vader Piet currently produces 13% of Aruba's load requirements, with an additional 26.4 MW slated to come online in late 2015. WEB Aruba aims to add 3 MW to 6 MW to the biogas plant, with a goal of using 70% of household waste. Therefore, Aruba needs more wind capacity to meet its energy demands.
Does Aruba aim for sustainable development?
Aruba has announced its commitment to sustainable development, as stated in the 2011 document titled "The Green Gateway". During the Rio +20 United Nations Conference on Sustainable Development in 2012, the country declared its goal to achieve 100% renewable energy use by 2020.
