AEG Power Solutions has commissioned a DC-3 power supply and a 230 kVA transformer. It operates a PEM electrolyser from the company H2B2, which produces 65 kg of green hydrogen per day for a filling station in Bogotá on behalf of the Colombian group Ecopetrol.
The Spanish engineering company H2B2 is a partner of the Colombian oil and coal group Ecopetrol, which is pursuing its own hydrogen strategy. Ecopetrol has contracted H2B2 to install the hydrogen production and refuelling system, worth US$3.5 million. This electrolytic hydrogen production plant is connected to a filling station for buses and light vehicles.
According to AEG Power Solutions, the power supply solution fits into a 40-foot container along with the H2B2 PEM EL30N electrolyser.
The DC-3 rectifier was chosen for its high efficiency in partial load scenarios. This is particularly the case when intermittent renewable energy sources feed the electrolysis process. AEG Power Solutions' hybrid approach combines the advantages of IBT and diode technology.
Power for hydrogen production in Colombia
Thanks to a low total harmonic distortion (THDi) and a very high power factor of up to 1, grid compliance can usually be achieved without additional compensation or filters, it says. According to AEG, the system has low DC ripple over the entire load range, which is required by many electrolyser manufacturers.
The system was delivered and commissioned by H2B2 earlier this year. Ecopetrol's entire hydrogen production facility was inaugurated in early March. H2B2's EL30N electrolyser produces almost 3 kg/h of green hydrogen for a bus in Bogotá's public transport system.
