The main priority for the strategy was to maintain the metal hydride temperature at room temperature, while increasing the FC temperature to the specified operating temperature. The preferred strategy for this system was to increase the fuel cell temperature to at least 40 degrees C before starting to heat the metal hydride storage unit to 30 C.
Without thermal integration, it was not possible to utilize the full hydrogen storage capacity of the metal hydride storage unit due to cooling of the tank.

After the workshop, it was concluded that EASAC should focus on the biggest challenge, namely road transport.
This report therefore examines decarbonisation of road transport, with only brief comments on rail, maritime and aviation transport.
It has separate chapters on demand and supply perspectives, and adopts a framework for tackling these challenges using sustainable solutions for the long term and transitional solutions for the short term. The literature study identified that in average kton goods where transported between the cities. The methodology used in the study is based on cost curves for both truck and infrastructure, and a case study with various scenarios is evaluated to find a profitable business case for both an FCET fleet and its infrastructure.
The cost curves for trucks are based on total cost of ownership TCO as a function of hydrogen price, while the levelized cost of hydrogen LCOH is Orbiting (Part I) - Ulises Labaronnie / Øystein Jørgensen - Saturn (File) to present the cost of infrastructure. The results show that an FCET purchased in can be competitive with biodiesel with a hydrogen price of While the hydrogen price can increase to To identify the most suitable infrastructure, four different designs of hydrogen refueling stations HRS were compared.
The analysis in this study showed that the most cost competitive option was a bar HRS without cooling, which only can serve type III onboard storage tanks. A HPU with alkaline electrolyzer was the most price competitive alternative.
When the TCO of the fuel cell truck and LCOH of the hydrogen infrastructure were compared for a scenario, no feasible solution was identified. The cost of installing three HRS Orbiting (Part I) - Ulises Labaronnie / Øystein Jørgensen - Saturn (File)serving a fleet of trucks, would cost In a future scenario, where both the FCET and infrastructure costs decrease due to expected learning curves, a business case can be found if at least 5 FCETs were refueling at each HRS on daily basis, which corresponds to a total fleet of approx.
Finally, a set of clear recommendations on how to improve the techno-economic analysis in future studies are provided. Both by identifying areas lacking sufficient documentation and by providing steps how the tecno-economic model could be enhanced. This thesis is devoted to the topic of energy storage system modelling, and to the integration of such systems to increase the utilisation of renewable energy. In particular, the use of a nickel-metal hydride battery storage system is considered in combination with energy produced by solar and wind to power an electric vehicle fast-charging station situated in Norway.
The thesis aims to develop a flexible model for the battery energy storage system that can accurately describe battery performance and performance-reducing effects.
The motivation of which is to be able to evaluate the feasibility of the charging topology in mention. A semi-empirical, battery model based on real data is designed and implemented in the Simulink modelling environment.
Further, a system model is developed in the same modelling environment which uses actual data from Norwegian renewable energy producers and charging station operators. We report on the influence of renewable energy mixture, capacity Orbiting (Part I) - Ulises Labaronnie / Øystein Jørgensen - Saturn (File), production sizing and vehicle charging behaviour on the feasibility of the topology. The topic is in line with an ongoing effort in the energy storage system research group to promote, design, model and validate the feasibility of energy systems powered by renewable energy sources.
The supply of hydrogen for zero emission transport is challenging, especially if the hydrogen is to be produced locally based on renewable energy sources. In order to claim zero emission in the full value chain from production to utilizationit is necessary to avoid CO2-emissions from the production and distribution of hydrogen. Reforming of natural gas with CO2-capture and storage is also an option, but this can only be realized in large centralized plants designed to capture and store several million tonnes of CO2 per year.
Hence, our options today are limited to reforming of biogas and renewable energy based water electrolysis. The focus in Norway is today on the development of water electrolysis based hydrogen supply systems. In Norway there is currently a national discussion on how and where to build up hydrogen refueling infrastructure. Some argue that a national network of bar hydrogen refueling stations must be established as soon as possible so that the market for fuel cell passenger cars can be allowed to grow faster, while others argue that we should focus on establishing bar stations for fleet vehicles such as trucks and buses.
On-site small water electrolyzer systems are modular, and can be developed for many different sizes and capacities. Hydrogen can also be trucked in from a centralized hydrogen production plant to the hydrogen refueling stations. A combination with some local hydrogen supply via water electrolysis and some trucked in hydrogen may also be an option. The focus in this presentation is on bar systems for fleets of heavy duty fuel cell vehicles trucks.
A techno-economic modelling tool which can be used to estimate the costs of different designs of water electrolysis based hydrogen refueling stations has been developed at IFE. This tool has been applied to different case studies over the past few years.
The program developed can be adjusted and used to access the techno-economics of a wide range of renewable power based water electrolyzers systems, including hydrogen compression, storage and dispensing systems.
The models are based on up-to-date technical performance data obtained from leading PEM and alkaline water electrolyzer and other hydrogen technology suppliers around the world, and cost data collected in various projects conducted at IFE over the past few years.
Results from techno-economic analyses of bar hydrogen refueling stations based on water electrolysis show how it is possible to find cost-effective system designs for small fleets of heavy duty vehicles.

Nullutslipp i transport. There is a growing interest for using renewable power to run water electrolyzers for on-site production of hydrogen for supply to various energy, industrial, Orbiting (Part I) - Ulises Labaronnie / Øystein Jørgensen - Saturn (File), and transport applications.
How can such systems become cost-efficient? A techno-economic modelling tool has been developed in order to try to answer this question, Orbiting (Part I) - Ulises Labaronnie / Øystein Jørgensen - Saturn (File). Several international companies supply on-site hydrogen production system, and the technology readiness level is high TRL However, on a system level it is still necessary to develop more energy and cost-efficient solutions.
In order to achieve this it will be necessary to both reduce the amount of materials used in the key components e. A simplified equation based techno-economic modelling tool has been developed in EES Engineering Equation Solver program.
