The case is made with oodles of footnotes and sources.
CHAPTER 4
Solar Hydrogen Utilization
4.4 Hydrogen Fueled Power Plants
Hydrogen can be used efficiently as fuel for thermoelectric power
plants. In 2010, Italys largest electricity utility (Enel) opened the worlds first hydrogen power combined cycle plant near Venice (Figure 4.15). Hydrogen is supplied using specially built pipelines from the nearby Polimeri Europa petrochemical plant, where ethylene-cracking is carried out.
The 12MW power plant comprises a hydrogen-fueled combined cycle plant and burns hydrogen gas in a turbine capable of resisting hydrogen embrittlement, which was developed in partnership with General Electric and generates both electricity and heat. The plant uses 1.3 tonnes of hydrogen per hour, has an overall efficiency of about 42%, and is essentially free of emissions. The efficiency of the process is increased by using the heat from the emissions to generate high-temperature steam, which is sent to the nearby coal-fired plant to generate an additional 4MW of power capacity. Overall, the electricity generated, equal to about 60 million kWh per year, will be sufficient to meet the needs of
20 000 households, avoiding more than 17 000 tonnes of CO2 emissions a
year...

Trivia: Did you know there are ~22 LITRES of Hydrogen Gas in ~1 Tablespoon of water? (1.2 tablespoons (one mole of water) makes 22.42 litres of H2 gas and 11.21 litres of O2 gas)
