“…In addition, compared to commercialized syngas storage and syngas combustion turbines, hydrogen storage and the hydrogen combustion GTCC are still in development. Technical difficulties must still be overcome, especially for hydrogen combustion turbines, such as flame stability and hydrogen embrittlement [26,27]. Therefore, no pure-hydrogen gas turbine system can currently be applied in large-scale commercial operation.…”

Regarding the carbon neutrality target, the proportion of renewable energy in global energy sources is predicted to increase to 50% by 2050, and the increment in penetration requires fossil fuel power plants to play a key role in grid peak regulation. The integrated gasification combined cycle (IGCC) is a promising peak-regulating method for power grids. However, due to the strong coupling between units, the flexibility of gas turbines cannot be fully utilized in response to power demand. This paper proposed a novel polygeneration system integrating syngas storage, hydrogen production, and gas turbines for power. Through syngas storage, the dynamic characteristic of each unit can be decoupled to take advantage of the flexibility of the gas turbine. Compared to the general IGCC system, the load change rate of the new system could be increased from 0.5%/min to 3-5%/min without altering the dynamic characteristics of the original equipment. The design capacity of the syngas storage tank could be reduced by decreasing the ramp rate of the power generation unit or increasing the load change rate of the gasification and hydrogen production units. For the new 300-MW system, the required syngas storage tank capacity reached only approximately 1872 m3 under storage conditions of 35 bar and 25 °C. Furthermore, the investment in the syngas storage tank only accounted for approximately 6.6% of the total investment cost. In general, the novel system can be more flexibly operated under variable loads with low carbon emissions, which can help to increase the penetration of renewable energy in the power grid.

“…However, hydrogen combustion could provide high-temperature heat in decarbonizing industrial applications currently powered by natural gas combustion that cannot be electrified directly. Like direct heating, hydrogen-based heat can be deployed for existing chemical production facilities, though some material changes and retrofits are likely required to enable hydrogen combustion 38 . One impediment to using hydrogen for high-temperature heat applications has been the low average costs of fossil-derived heat.…”

The chemical industry is a major source of economic productivity and employment globally and among the top 3 industrial sources of greenhouse gas (GHG) emissions, along with steel and cement. As global demand for chemical products continues to grow, there is an urgency to develop and deploy sustainable chemical production pathways and re-consider continued investment in current emissionintensive production technologies. This Perspective describes the challenges and opportunities to decarbonize the chemical industry via electrification powered by the low-emission electric power sector, both in the near-term and long-term, and discusses four technological pathways ranging from the more mature direct substitution of heat with electricity and use of hydrogen to technologically less mature, yet potentially more selective approaches based on electrochemistry and plasma. Finally, we highlight the key elements of integrating an electrified industrial process with the power sector to leverage process flexibility to reduce energy costs of chemical production and provide valuable power grid support services. Unlocking such plant-to-grid coordination and the four electrification pathways has significant potential to facilitate rapid and deep decarbonization of the chemical industry sector.

“…20 In the materials compatibility for a hydrogenfired gas turbine, the most important is the smaller flame-wall quenching distance, due to which temperature gradients across air-cooled components rise. 21 In order to provide full insight to the different applications of hydrogen in the mechanical and electrical power, a special issue focusing on the hydrogen utilization in engines has also been published recently. 22 This study reviews and presents the material considerations and compatibility of metals and their alloys in H 2 -ICEs, following the one from the same Authors on Rubbers and Elastomers.…”

Hydrogen internal combustion engines (H2-ICEs) are being examined primarily owing to their low criteria pollutants and zero carbon dioxide emissions. However, there are many components and systems of a H2-ICE (including, i.e., gaskets, fuel injection system, piston, cylinder head, exhaust manifolds,…) that are exposed to direct or indirect high-pressure and temperature hydrogen that can lead to deterioration and degradation of the materials, in particular rubbers, metals and their alloys. In the present article, the implications on the characteristics of metals and their alloys exposed to a hydrogen atmosphere are examined with reference to the typical materials and respective operating conditions found in H2-ICEs. The effects of direct or indirect exposure of high pressure and low/high-temperature hydrogen on the properties including mechanical properties of metals and their alloys have been explored. Finally, based on the previous review, a critical assessment of their suitability for a safe and reliable operation on H2-ICEs is provided.
