Renewable energy, low reliability + Electrolysis Fossil/Renewable, high reliability Cap. COST/MW Cap. COST/MW $1.3 million -  $2.2 million $1.11 million (plant cost) $2 million - $5 million SOFC/MCFC $5.56 million (nevada) CoalSNG/ bioSNG Gas Turbine Coal -> CO2 Bio -> Almost 0 CO2 $1.20/kg hydrogen $5.40/kg hydrogen Hosseini, S.

7 Hydrogen production method, comparison
Electrolysis of Hydrogen vs. Gasification Coal gasification With current state of technology and worldwide coal reserves, coal is an economical and technically practical option to produce hydrogen in large scale plants. Compared to the existing methods (i.e. electrolysis), gasification is more suitable for converting coal to hydrogen. This method causes higher CO2 emissions compared to other available hydrogen production technologies CCS -> Clean Energy Dincer, I. and C. Acar (2015).

8 Hydrogen production utilizing coal gasification
Gasification reactions: WGS conversion is favoured at low temperatures, while reaction kinetics are favoured at high temperatures Water-gas shift (WGS) reactions: The WGS reaction is often conducted in at least two stages: first a high temperature step (HT WGS) at oC and bar where fast reaction is favoured, then a low temperature step (LT WGS) at oC and bar where a high conversion is favoured. GE gasification system, the gasification pressures up to 100bar and temperatures are in the range oC Shell gasifiers typically operates at pressures of bar and temperatures of oC Voldsund, M., et al.

11 Conclusions Hydrogen production using gasoline is the cheaper way (US$0.93/kg), the second cheap method is using coal gasification (US$1.03/kg) 2. Coal gasification for hydrogen production capital cost is the lowest available. 3. Coal gasification + CCS for hydrogen production is one of the solution to reduce GHG with a cheap manner in hydrogen production. 4. Coal gasification is a solution for the transition changing from carbon energy cycle into hydrogen energy cycle. The technology is mature enough and ready to use.
