“…Combustion air is fed to the turbine at a stoichiometric ratio of 3.7. The high airflow provides cooling, which reduces nitrogen oxides (NO x ) emissions (Dennis 2008a, Dennis 2008b, Juste 2006. NO x emissions could be reduced further using a catalytic process.…”

One of the primary strategies proposed for integrating large amounts of renewable energy is using energy storage to absorb excess electricity-generating capacity during times of low demand and/or high rates of generation by renewable sources and then reconverting this stored energy into electricity during periods of high demand and/or low renewable generation.Various energy storage technologies have been developed or proposed. The goal of this analysis was to develop a cost survey of the most-promising and/or mature energy storage technologies and compare them with several configurations employing hydrogen as the energy carrier. A simple energy arbitrage scenario was developed for a mid-sized energy storage system consisting of a 300-MWh nominal storage capacity that is charged during off-peak hours (18 hours per day on weekdays and all day on weekends) and discharged at a rate of 50 MW for 6 peak hours on weekdays.For all the hydrogen cases, off-peak and/or excess renewable electricity is used to electrolyze water to produce hydrogen, which is stored in compressed gas tanks or underground geologic formations. The hydrogen is reconverted into electricity using a polymer electrolyte membrane (PEM) fuel cell or hydrogen expansion combustion turbine. The hydrogen storage scenarios are compared with the use of several battery systems (nickel cadmium, sodium sulfur, and vanadium redox), pumped hydro, and compressed air energy storage (CAES).All the energy storage systems are evaluated for the same energy arbitrage scenario using consistent financial and operational assumptions. Costs and performance parameters for the technologies were gathered from literature sources and, in the case of the hydrogen expansion combustion turbine, Aspen Plus modeling. Producing excess hydrogen for use in vehicles or backup power is also evaluated. Two production levels are analyzed: 1,400 kg/day (roughly equivalent to the U.S. Department of Energy's standard model for smallscale distributed hydrogen production) and 12,000 kg/day. As for the purely energy arbitrage scenarios, it is assumed that hydrogen would be produced with offpeak/renewable electricity. Cost results for the analysis are presented in terms of the annualized ("levelized" 1 Figure ES -1 ) cost for producing the energy output from the storage system: electricity fed back onto the grid during peak hours ($/kWh) and, in the case of producing excess hydrogen for vehicles, hydrogen ($/kg).summarizes the comparison of levelized cost of delivered electricity for hydrogen (green bars) and competing technologies (blue bars). For each technology, high-cost, mid-range, and low-cost cases were analyzed, and sensitivity analyses were 1 The leve...

“…To sequester and store the CO2 of fossil fuel, some new research projects aim to assess the combustion performances of alternative fuels for clean and efficient energy production by gas turbines. Another objective is to ex-tend the capability of dry low emission gas turbine technologies to low heat value fuels produced by gasification of biomass and H2 enriched fuels [8][9][10]. Significant quantity of hydrogen in fuel has the benefit of high calorific value, but the disadvantage of high flame speed and very fast chemical times.…”

“…Most of these previous works have focused on non-premixed combustion systems (Conrad and Corrington 1957;Nomura, Tamaki et al 1981;Sampath and Shum 1985;Tomczak, Benelli et al 2002;Juste 2006;Cocchi, Provenzale et al 2008;Cocchi and Sigali 2010). Some work with regard to the operation of premixed systems on high hydrogen content fuels has also been carried out (Minakawa, Miyajima et al 1997;Farina, Perry et al 2009;Perry, Farina et al 2009;Therkelsen, Werts et al 2009).…”

“…However, the fact that the NOx emissions do not increase as hydrogen is added does not agree with those trends from the PSR simulations. It should also be noted here that several publications contain experimental data showing an increase in NOx as hydrogen is added to natural gas (or another baseline fuel) (Tomczak, Benelli et al 2002;Juste 2006;Cocchi, Provenzale et al 2008) or substituted for the original fuel (Nomura, Tamaki et al 1981;Sampath and Shum 1985;Therkelsen, Werts et al 2009). However, other publications show experimental data with sub 1 ppm NOx measurements after several design modifications (Minakawa, Miyajima et al 1997;Farina, Perry et al 2009).…”
