Increasing in Telecommunications Demand Indicators of Brasil Telecom (Acces-million) Mobile phone: 157,5 Fixed: 41,7 Broadband: 10,4 Cable TV: 6,6
Projeto Data Center - Affordable Internet Services Online Inc.
Technology Pros and Cons Clean Energy Silent Free and Infinite Modular Well suitable for stand alone applications Low maintenance costs Long lifetime Simple operations High cost Low efficiency Efficiency Degradation Storage systems Operating conditions (poor light conditions) Temperature sensibility Low power density
Technology Pros and Cons Clean Energy Easy to manufacture Suitable for Large applications Stand alone systems Connected with the grid Competitive Price Huge unexplored potential Noise and visual pollution Competitive Price Low capacity factor Operating conditions (seasons and wind speed dependence) Heavy Infrastructure to install
Available Technologies Fuel Cell Technology Temperature range (ºC) FuelMarket Availability AFC50 - 200H 2 (pure) O 2 (pure) Commercial (??) PEMFC60 - 80H 2 (99,95%) O 2 (from air) Commercial (Stationary) PAFC100 - 200H 2 NG Commercial MCFC600 - 750NG H 2 Pre - commercial SOFC800 - 1000NG H 2 Pre - commercial DMFC60 - 80MethanolUnder development
Stationary application - Telecom Electrochemical device – DC supplier; It is a suitable solutions in extreme conditions; It helps in a low carbon footprint; It is a interesting solution more, not is the BEST solution. It is better when used combined with other energy sources (batteries, PV and wind)
Technologies Pros and Cons Run time Environment temperature resistance range (- 25 º to 45 º C) Silent Clean Energy Life time Low Maintenance No recharge time Remote control Start up High cost Poor field database Hydrogen cost Refueling Standards and codes
Hybrid System PV - Wind - Diesel - São Tomé - Brazil
Average Prices (U$/Kw) Fuel cell – U$ 3,000/Kw Solar Photovoltaic – U$ 400 – 1,000/Kw Wind Energy – U$ 0,11 – 0,22 /Kwh * * Last prices in Brazil
Conclusions Today the people are more consciences about the environments In Brazil the using the renewable energy in telecommunications companies is small This type the energy is expensive, it is necessary the incentive programs *
