Hydrogen can be produced using fossil fuels, or from renewable energy sources such as nuclear energy, biomass, wind, solar, geothermal, and hydro-electric power—using a wide range of processes. Though currently, the vast majority of hydrogen is extracted using fossil fuels, falling renewable power costs and improving electrolysis technologies could make "green" hydrogen cost competitive by 2030.
Under one design/build contract, TIG/m can provide complete hydrogen-cycle equipment including:
On-site hydrogen generation.
Hydrogen compression and storage.
Hydrogen fuel dispensing.
On-board fuel cell generators that charge the batteries while the streetcar is in passenger service.
