“…The research on the economic dimensions of business models along the value chain for using hydrogen in transport is growing. Earlier studies have focused on techno-economic factors and how to achieve a profitable renewable hydrogen investment business case [2][3][4][5][6][7][8][9][10][11][12][13][14]. There are case studies using European settings, e.g., [3,8,10,14] set on German market conditions, [4,12] in an Austrian context, [7] in Ireland, [9] in France and [2] in a Danish setting.…”

An improved understanding of the emerging business models for hydrogen applied in the transport sector is crucial to remove barriers for hydrogen uptake. The aim of this study is to create a characterisation of the current landscape for hydrogen road mobility in Sweden by mapping out the business model for hydrogen producers, hydrogen filling station owners and hydrogen vehicle manufacturers. This has been achieved by interviewing hydrogen market actors in the Swedish transport sector and through validation of the results in an expert elicitation. The main finding of the study is that the business model is still emerging and contains large uncertainties also about the viability of the business case. This is noticeable for example in the key partner section in the business model. Actors seek out partnerships and collaboration both horizontally and vertically along the hydrogen value chain, even with future competitors, to create a critical mass of supply and demand to enable the hydrogen market to take off. Additional value propositions and revenue streams, such as support services to the electrical grid and utilisation of residual products (excess heat and oxygen), are secondary in the business model today.

“…The aforementioned studies have all contributed to understanding the design and planning of integrated systems based on Power-to-Gas and Gas-to-Power. However, further research is required to put their evaluations in the context of various scenarios and case studies [14], [15]. Papers that combine both a techno-economic and environmental assessment are also less common.…”

This work aims at sizing a power supply system composed of a wind plant, an electrolysis plant, a compressor, a storage tank, and a hydrogen-fueled gas turbine power plant to deliver low-carbon electricity. This system offers the benefit to be a dispatchable power supply system, needed to deliver flexibility on the grid. For this Power-to-Power system, the sizing objective is to find the minimal functional sizes for all the components of the system. The sizing is done for the case of Germany in 2021. Two system plannings are considered: one in which demand is supplied solely by the gas turbine and the wind plant is dedicated to green hydrogen production, and a second one in which wind plant produces hydrogen and supplies demand while gas turbine completes balance. We also evaluate the capital and operational costs of the system, as well as its water usage and land footprint. Sizing results computed show that using an integrated approach in which planning is done to exploit the synergies between the wind plant and the gas turbine not only generates gains in costs, space and water usage, but also avoids over-sizing the system.

Multi-stage reverse electrodialysis (MSRED) offers a promising way for efficient salinity gradient energy harvesting. Here, an improved model of the MSRED system under serial control strategy is proposed. The technical–economic analysis is conducted with considering discount, depreciation and different regional tax and electricity price levels under the maximum net power output conditions. Results reveal that net power output and energy efficiency both increase first with increasing stage numbers, reach their maximum values, and then decrease. For 5 M/0.05 M solutions, the optimal net power output of 4.98 kW is obtained at the stage number n = 12. The optimal stage number corresponding to the maximum net power increases with increasing feed solution concentrations. Due to the compromise between net power generation and capital cost, there exist optimal stage numbers leading to the lowest LCOE and largest NPV, respectively. Higher feed solution concentration can significantly decrease the system LCOE and increase the NPV. The optimal stage number corresponding to the maximum NPV increases with increasing feed solution concentrations. In Germany, for 5 M/0.05 M solutions, the lowest LCOE of 0.061 €·kWh−1 is achieved at n = 3 while the highest NPV over the system lifecycle of 52,005 € is obtained at n = 8. Lower tax, higher electricity price, appropriate membrane price and stage numbers, and high salinity gradient sources can significantly accelerate the commercial completeness of the MSRED systems.
