Objective
The objectives of this project is to demonstrate the feasibility of a PEM Fuel Cell for generating electricity from waste gases from an industrial process. The power unit is targeting to produce a 200kW net power and is based upon a 240 kW PEM stacks. The consumption of auxiliaries for operating the power unit have an estimated power of 40 kW. Reliability, safety and economics of the system and more peculiarly of the air compression system and hydrogen feeder are emphasised in order to provide the complete system with low maintenance operation and costs.
The industrial process is the AIR LIQUIDE liquefied hydrogen production plant located in Wazier, North of France, which, in normal operation is venting some gaseous hydrogen to the atmosphere without recovery. The idea is to fed the PEMFC with some of this wasted hydrogen. The D.C. current is converted to standard A.C.current (250KVA, 50Hz, 400 Volts Tri.) used to supply some equipment of the plant.
Technical results :
- achievement of a european technology prototype of a 200 kW stationary power plant using PEM fuel cell, connected to an industrial process
- use of waste hydrogen as the fuel for a PEMFC
- use of a high efficiency (50% converter (fuel cell) incorporated in a maintenance free system (maintenance lower than 1 day/year)
Commercial and markets results :
-Diffusion of the results to the first market : chlore alcali industry (which produce waste hydrogen at a energy level of 13 Nm, corresponding to a potential production of 13000 MW of electric power) after that first step, we will target the second
market : Petroleum refineries, ammonia plants, hydrotreaters and hydrocrackers,...
The innovating aspects are :
- implementing of an european PEM fuel cell at a power level of 200kW for a stationary application - use of that demonstration prototype as an energy saving system within an industrial existing process and possibility of back experience.
- coupling of an original D.C generator (PEMFC) to a standard AC network.
- implementation of a numerical simulation tool describing a stationary PEMFC power plant
-demonstration of a maintenance free system (fuel cell and no maintenance gas bearing air compressor)
AIR LIQUIDE is operating in Wazier, a 10 tpd hydrogen plant. The hydrogen is coming from a chemical amonia plant as a by-product mixture of 90% hydrogen and 10% nitrogen. After purification, the hydrogen is liquefied and stored in four 250 m³ liquefied hydrogen superinsulated cryogenic storage tanks which boil-off are returned to the cold box of the process cycle reliquefaction. The liquefied hydrogen is trucked out of the plant to the customers sites by rail, road and sea dedicated cryogenic transportation trailers or containers. When coming back to the plant for refilling,
the gas phase of the trailers is vented to the atmosphere and wasted. This gas phase of the trailers is not returned to the process cycle for reliquefaction because pollution is suspected and its recovery would require a costly purification. This wasted hydrogen yields roughly 2 Million Nm³ per year, equivalent to 10% of the total plant production capacity.
The PEMFC stationary project consists in a power generating unit recovering this wasted hydrogen and contributing to the energy savings of the plant. An hydrogen feeder recovers the cold hydrogen from the trailers, and peakshave it from an erratic maximum 2400 Nm³/h flow to a steady low pressure 150 Nm³/h flow required for feeding the 200 KW PEMFC. Then, the converter and used to supplied some selected equipments of the plant. The connection of the unit to the grid will be investigated during this project but not implemented. The unit is operated automatically by a computer and remotely controlled via a modem link.
