“…Involvement in such a market promises a myriad of potential benefits: from reduced global CO2 emissions, in particular, from several sectors that have otherwise proven difficult to decarbonise (e.g. industrial heat, steel and cement production, heavy transport and large-scale machinery: Bataille et al, 2018;Kato and Kurosawa, 2019;National Hydrogen Strategy Taskforce, 2019a;Friedmann et al, 2019); to helping to stabilize electricity grids reliant on intermittent renewable-energy sources (Gutiérrez-Martín and Guerrero-Hernández, 2012;Bennoua et al, 2015;National Hydrogen Strategy Taskforce, 2019a); to increasing diversification and energy independence through the addition of a new fuel into the energy supply (US DOE, 2002;Ball and Wietschel, 2009;Ren et al, 2014;Scita et al, 2020). However, the unprecedented scale and complexity of this new industry calls for careful planning -requiring the creation of economic models and datasets capable of assisting policy makers and industry members to implement new hydrogen projects and supporting regional infrastructure (e.g.…”

Assessments of hydrogen project viability typically focus on evaluating specific sites for development, or providing generic cost-estimates that are independent of location. In reality, the success of hydrogen projects will be intimately linked to the availability of local energy resources, access to key infrastructure and water supplies, and the distance to export ports and energy markets. In this paper, we present an economic model that incorporates assessments of these regional factors to identify areas of high economic potential for hydrogen production -the so-called "Economic Fairways" for such projects. In doing so, the model provides a tool that can be used to inform investors and policy makers on the available opportunities for hydrogen development and their infrastructure requirements. The model includes analysis of the regional economic potential for both blue and green hydrogen projects. It accounts for hydrogen production from renewable (wind and solar) sources, as well as non-renewable sources (steam-methane reformation and coal gasification) combined with carbon capture and storage. Results from case studies conducted with the tool are presented, illustrating the potential for hydrogen production across Australia.

“…We note a range of results when utilizing flexible electrolysis, coupled with hydrogen storage, as a support mechanism for the electric power system. Bennoua et al (2015) model the introduction of flexible electrolysis and hydrogen storage in the French power system, examining its potential use for load following (in the context of France's large baseload nuclear capacity), as well as for use as a balancing mechanism for variability in generation (Bennoua et al, 2015). Guinot et al (2015) take an economic view and focus on the profitability of electrolysis-based hydrogen production for grid balancing in France.…”

Role of Hydrogen in a Low-Carbon Electric Power System: A Case Study

The European Union set a 2050 decarbonization target in the Paris Agreement to reduce carbon emissions by 90–95% relative to 1990 emission levels. The path toward achieving those deep decarbonization targets can take various shapes but will surely include a portfolio of economy-wide low-carbon energy technologies/options. The growth of the intermittent renewable power sources in the grid mix has helped reduce the carbon footprint of the electric power sector. Under the need for decarbonizing the electric power sector, we simulated a low-carbon power system. We investigated the role of hydrogen for future electric power systems under current cost projections. The model optimizes the power generation mix economically for a given carbon constraint. The generation mix consists of intermittent renewable power sources (solar and wind) and dispatchable gas turbine and combined cycle units fueled by natural gas with carbon capture and sequestration, as well as hydrogen. We created several scenarios with battery storage options, pumped hydro, hydrogen storage, and demand-side response (DSR). The results show that energy storage replaces power generation, and pumped hydro entirely replaces battery storage under given conditions. The availability of pumped hydro storage and demand-side response reduced the total cost as well as the combination of solar photovoltaic and pumped hydro storage. Demand-side response reduces relatively costly dispatchable power generation, reduces annual power generation, halves the shadow carbon price, and is a viable alternative to energy storage. The carbon constrain defines the generation mix and initializes the integration of hydrogen (H2). Although the model rates power to gas with hydrogen as not economically viable in this power system under the given conditions and assumptions, hydrogen is important for hard-to-abate sectors and enables sector coupling in a real energy system. This study discusses the potential for hydrogen beyond this model approach and shows the differences between cost optimization models and real-world feasibility.

“…Then, at a peak demand, a fuel cell uses the hydrogen to quickly respond to loads and thus providing short-term energy deficit. In addition to being used in fuel cells, hydrogen production can be used for other purposes, such as fueling vehicles or it can be distributed through the gas grid [6].…”
