Regenerated Energy

Project name : Development of single cycle convergent ESS applied with nano-carbons to save the energy of elevating devices
Participating organizations : VINATech, Leekun Industrial Systems , Sangoh Precision , Korea Electronics Technology Institute , Korea Institute of Carbon Convergence Technology , Chonbuk National University , Kunsan National University
Project period : May 1, 2015 ~ April 30, 2018 [36 months]
Project budget : 3.68 billion KRW (including 2.76 billion KRW in government contributions)

More than 500 elevators for facilities higher than 30 floors have been installed every year since 1996. Over 700 elevators were installed in 2014, and over 2,000 elevators were installed in the same year, if the elevators for facilities higher than 25 floors are included. As the number of high-rise elevators increase, increasing the capacity of super capacitors is required (At least in the case of Korea.).
The space of the elevator machine room becomes smaller to reduce construction costs, which also requires the ESS (Energy Storage System) and the reduction of the DC-DC converter size, and increases demand on high-capacity super capacitors.
The development goals of this project are to develop the world’s best energy saving ESS and enter new markets, based on “improved materials”, “cell, module and CMS”, “DC-DC converter” and “cooling system” technology.

The effects of power consumption reduction are expected to be 2,565GWh every year, by saving regenerated energy that is generated when the elevator goes down. In addition, it is expected to take about 4 years to recoup the investment.
Basis of estimation
-Number of elevators in facilities higher than 25 floors: 500,000 car/country

-Annual power saving per elevator: 5,130kWh/year·car (assuming 14 hours of daily operation)

-Electric power efficiency: 121 KRW/kWh

-Power consumption reduction = 500,000 car/country * 5,130kWh/year·car = 2,565GWh

-Reduced electrical bills = 2,565GWh * 121 KRW/kWh = 310 billion KRW
