“…Kasai [4] discussed the hydrogen energy storage with two different energy mix scenarios: one with large scale renewable energy penetration corresponding to highly fluctuating energy supply and one with nuclear power plants with highly fluctuating energy demand. In 2013, Gahleitner [5] wrote a comprehensive review about the power to gas solutions which could cope with intermittent power generation from renewable energy sources highlighting the need for further research to improve the efficiency, reliability, lifetime and costs of electrolyzers and fuel cells as well as to develop codes and standards for the use and storage of hydrogen.…”

Electrical energy storage (EES) systems allow shifting the time of electric power generation from that of consumption, and they are expected to play a major role in future electric grids where the share of intermittent renewable energy systems (RES), and especially solar and wind power plants, is planned to increase. No commercially available technology complies with all the required specifications for an efficient and reliable EES system. Reversible solid oxide cells (ReSOC) working in both fuel cell and electrolysis modes could be a cost effective and highly efficient EES, but are not yet ready for the market. In fact, using the system in fuel cell mode produces high temperature heat that can be recovered during electrolysis, when a heat source is necessary. Before ReSOCs can be used as EES systems, many problems have to be solved. This paper presents a new ReSOC concept, where the thermal energy produced during fuel cell mode is stored as sensible or latent heat, respectively, in a high density and high specific heat material and in a phase change material (PCM) and used during electrolysis operation. The study of two different storage concepts is performed using a lumped parameters ReSOC stack model coupled with a suitable balance of plant. The optimal roundtrip efficiency calculated for both of the configurations studied is not far from 70% and results from a trade-off between the stack roundtrip efficiency and the energy consumed by the auxiliary power systems.

“…Electrolytic hydrogen production from water (Kasai, 2014;Kelly, 2014) consuming around 48 kWh electricity per kg hydrogen in today's electrolysers (Gardner, 2009) is an established technology, however, it is energy intensive. Fermentative bio-hydrogen, overcomes this issue but suffers from low yields.…”

The aim of this study is to develop an industrial ecosystem whereby wastes/products from a Postcombustion CO 2 Capture (PCC) plant are utilised in a hydrogen biorefinery. Subsequently, five hydrogen biorefinery models are developed that use PCC's model amine i.e. monoethanolamine (MEA) as a nitrogen source during microbial hydrogen production and CO 2 as a process chemical. Technical evaluations of the five case models are carried out to identify the ones that maximise value by multiproduct generation from biomass and fulfil total/partial parasitic energy demand. The case meeting these criteria, produces 3.1t of succinylated lignin adhesive, 4.9t of dry compost and 2744kWh of electricity from 10t (dry) of sawdust feedstock, daily. Its daily power and heat duties stand at 3906kWh and 52.1GJ respectively. Simulations also demonstrate biohydrogen's potential as an energy storage vector for peak/backup power with an annual 1001.4MWh of power storage capacity from 10t/d feedstock.

We have developed high-performance double-layer (DL) hydrogen electrodes for reversible solid oxide cells. The DL hydrogen electrode consisted of mixed conductor, samaria-doped ceria (SDC), with highly dispersed Ni or Ni-Co nanocatalysts as the catalyst layer (CL) and, on top of it, a thin Ni−SDC cermet as the current collecting layer (CCL). The performance of the DL hydrogen electrode was appreciably improved by controlling the microstructure. The use of a thin, porous CCL increased the electronic conducting path to and from the CL, while maintaining sufficient gas-diffusion rates of H 2 and H 2 O, and enlarging the effective reaction zone at the CL. The optimum CCL thickness was found to be 5 μm. The IR-free overpotentials η at the optimized DL hydrogen electrode in humidified hydrogen (p[H 2 O] = 0.4 atm) and T cell = 800 • C were 0.20 and −0.20 V at j = 0.5 and −0.5 A cm −2 , respectively, indicating a highly reversible operation. The use of a full cell with the configuration of Ni 0.9 Co 0.1 /SDC DL hydrogen electrode|YSZ electrolyte|SDC interlayer|LSCF−SDC O 2 electrode led to very promising results for the SOEC operation in which an IR-free electrolytic cell potential of 1.21 V at j = −0.5 A cm −2 and 800 • C was achieved. Nowadays, hydrogen is attracting much attention as an energy carrier suitable for long-term and large-scale storage. Electrolysis of water is one of the effective technologies to produce pure hydrogen in a single step. Among the various types of electrolysis cells, solid oxide electrolysis cells (SOECs) operating at high temperature (800-1000• C) present the highest conversion efficiency due to favorable thermodynamic and kinetic conditions. 1-7 An SOEC can be operated in reverse mode as a solid oxide fuel cell (SOFC) that directly converts the chemical energy in hydrogen gas into electrical energy with a high energy conversion efficiency. Thus, a reversible solid oxide cell (R-SOC) is regarded as an efficient reciprocal energy converter between hydrogen and electricity.
