1 Introduction of two HFC projects: realised: PEM fuel cells as UPS in the telecom sector plan: hydrogen powered buses and railway engine Zoltán Mayer, secretary, HHFCA Budapest, május 7.

2 1. PEM fuel cells, as uninterruptible power supply (UPS) at the Hungarian Telecom Plc. (realized, operating project) The presentation is based on results obtained by György Bucsy,, Dr. PálGéza Nagy, Csaba Várfalvai (Hungarian Telekom Plc.)

3 -function of fuel cells: UPS uninterruptible power supply -one of the most important application at this time in Hungary (pcs, kw) -did not require any public founding (R&D or from other sources) -realized by a profit-oriented company (return is expected; no charity ) -background: base station(bs)electricity demand: 5-6 kw > 30% of energy used for air conditioning > Hungarian grid: 1,5 powerbreak/year; 40 min. without power/bs > previous UPS technology: lead acid batteries (weight: 2 t 1,5 t Pb) > batteries lifetime: 5-8 years; temperature control betw o C > thermal shock can reduce lifetime considerably (halved) info@hfc-hungary.org +

4 Energy saving Air conditioning of the base stations is used to control the working temperature. It can be replaced by fresh air ventilation and geocooling The substitution of batteries with other backups allows to increase the temperature up to C kw Sizing of cooling capacity with fresh air ventilation at BTS. temperature diff. between inside and outside dt 6 C dt 8 C dt 10 C Ventilation in Vm 3 /h

5 -facts: 13 fuel cells (at 13 BS locations); all of them are PEM FC capacity: 5 kw e each (48 V, max 105 A DC) fuel: 11 hydrogen, 2 methanol (reforming H2) partners: Altergy(FC, Linde Hungary (H2) timing: 2008: 1 PEM FC 2009: 5 PEM FC 2010-: 7 db PEM FC back-up time: 0,8 kg/h 2 bottle: 2 h 42 min (x 2 bottles; 200 bar) Arrangement EExbox, electric adapter Arrangement of PEM Fuel Cell Outdoor mounting. H2 bottles in protected cabinets with extraction generator pictures: Hungarian Telekom

7 Signals (alarm signals if necessary) to be watched through the remote control: Gas pressure in bottles Gas pressure in the cell H 2 leakage Operation (Offline, Stand-by, Running) Power level (54 V DC) Electric current level (max. 100A) Receiving fault codes Signals to be watched and treated on site: Level of battery power: decreasing (mains blackout), increasing Detection of outside and inside temperature (moving the shutter) Software expectations: SNMP communication protocol Possibility of remote operation to set the parameters and to download the firmwares

8 -locations: Pest county (Rétság, Göd, Gyál, Györmő, Kispest, Pestlőrinc, Mogyoród, Ócsa, Alsónémedi, Pomáz, Seregélyes, Rákoscsaba, Sződliget) - optimization, evaluation ongoing: H 2 supply: rechargeable vs. replacable bottles vs. on-site production of H2? - H2 purchasing and logistic is solved -good news: technology proven; H2 logistic; environmental benefits Budapest -bad news: too long payback time (7-9 years); no more FC installation temporarily. Hungarian grid is too good + BSs are densely located. (Telecom Italia: 250+ db PEM FC) we are here

10 2. Hydrogen powered (ICE) buses in Miskolc, and hydrogen powered narrow-gauge railway in Lillafüred (planed project) The presentation is based on results obtained by Lajos Szalontai (Linde Hungary)

11 Background: Miskolc former industrial city, with ratherold bus fleet; air quality problems(~ inhabitants) - Bükk National Park area -famous (two) narrow-gauge railway line: 2 x 14 km (built: 1922) tourist attraction: with highest attendance among forest railways in Hun. -LindeHungary Co.: HyCO Plants in Kazincbarcika (~ 25 km) -HyCOlocated within a chemical giant (BorsodChem) 25 km -hydrogen production: SMR method, with relatively low environmental loading source: Bükk Natinal Park

12 Some pictures about the surroundings

13 Developments till now: a 40 years old locomotive was rebuilt (2010) with hybrid (diesel-electric) drivetrain (seeonthepicture) Project idea: - 2 hydrogen fuelled ICE(!)-BEV busses for public transport - 1 hydrogen fuelled ICE(!)-BEV(hybrid) locomotive - 1 hydrogen refuelling station (HRS), with 350 bar dispenser Why ICE instead of FC? (in the first phase) Because of much lower -costs. Fuel cell (FC) drive train is too expensive. One have to wait some years until FC prices will fall (new R&D results, mass production ) H-ICE: Ford Duratec 110 kw(?) picture: L. Szalontai Hydrogen refuelling infrastructure can be demonstrated even in this way In a later phase FC buses can be procured (using the same HRS)

14 Why are the two endusers(bus, forest rail) connected in this project? One infrastructurecan serve both endusers: one hydrogen storage one compressor onecgh2 unloading station from H2-trailer two dispensers ~50 m H2-pipline. In later stage HRS can be suitable for H2 refuelling of FC cars, as a public station?!? (triple advantage) Miskolc, Majláth bus terminal- forest rail station(~40 m) Hegyalja str.
