From industry to the transport sector, hydrogen can address a wide range of needs. This chapter paints a global picture of hydrogen's current and future applications. For each of these applications, we discuss the potential for economic competitiveness by highlighting the main drivers and variables: hydrogen's competitors, and price and cost goals for hydrogen. But beyond the possible markets for hydrogen, hydrogen systems could offer broader services. Thanks to the characteristics of hydrogen production, hydrogen systems could enable a more environment-friendly, smart energy system. We examine this in the last part of the chapter, with a special focus on services that hydrogen systems could potentially provide to the electric system.

The economic benefits in terms of Total Cost of Ownership (TCO) are based on forecasts for the major TCOinfluencing parameters up to 2030: electric driving distances, energy (fuel, electricity, hydrogen) prices, batteries and fuel cell costs. The model takes into account functional parameters such as the battery range as well as daily trip segmentation statistics. The TCOs of all the vehicles become similar in 2030, given a 200 km battery range for BEVs. BEVs are profitable for yearly mileages of 30,000 km and over, and for higher battery ranges. The competitiveness of FCEVs is examined through the H 2 target price at the pump. There is a very significant effect of the fuel cell cost on the TCO. A FCEV with a fuel cell cost of 40 V/kW will be competitive with a similar ICE car for a 1.75 V/l fuel cost and ca. 7 V/kg hydrogen cost. This depends too to a great extent on possible ICE cars' CO 2 taxes. As regard the FC-RE electric car, the hydrogen target price at the pump is noticeably higher (ca 10 V/ Kg). FC-RE cars TCOs are strongly affected by the FC power, the discount rate chosen and the yearly mileage. Moreover, it therefore seems reasonable to confine FC-RE battery ranges in the region of 60 km.

Five hydrogen delivery pathways, going up to the refuelling stations, are compared. Three scenarios are investigated for the hydrogen demand in passenger mobility. GIS modelling allowed to visualize a potential infrastructure deployment. The economies of scale have significant impact on lowering the hydrogen cost.

However, the economic performances of such systems generally remain unclear because of unspecified or favourable assumptions and operating conditions. The aim of this paper is to clarify these conditions by examining how the hydrogen produced is used. The analysis which has been conducted in the framework of the HyFrance 3 project concerns hydrogen for transport applications. Different technical systems are considered such as motorway hydrogen filling stations, Hythane®-fueled buses or second-generation biofuels production which present contrasted hydrogen use characteristics. This analysis reveals considerable variations in hydrogen production costs depending on the demand profiles concerned, with the most favourable configurations being those in which storage systems are kept to a minimum.

L'objet de ce papier est d'expliciter ces conditions en précisant les conditions d'utilisation de l'hydrogène produit. Les analyses présentées ici pour les usages transport font apparaître une grande variabilité des coûts de production de l'hydrogène selon les profils de demande considérés avec un net avantage pour les configurations limitant au maximum le recours à des dispositifs de stockage.

The main topics are as follows: (1) behavior of the different grades of zirconium, (2) influence of metallurgical state, environment characteristics and some practical uses, and (3) resistance to stress corrosion cracking. In most cases, the results were satisfactory and zirconium showed an outstanding behavior in comparison with stainless steels.

HyFrance3 is a new project that focuses on the economic competitiveness of different steps of the hydrogen chain, from the production to end usage, at the time horizon of 2030 in France. The project is coordinated by CEA with the other partners being: ADEME (co-funding), AFH2, CNRS, IFP, Air Liquide, EdF, GdF Suez, TOTAL, ALPHEA. The project is divided into 4 sub-projects, that address present and future French hydrogen industrial markets for chemical & refinery uses, the analysis of the interplay between wind energy production and storage of hydrogen for different automotive requirements (refuelling stations, BtL plants, H 2 /NG mix), massive hydrogen storage to balance various offer and demand characteristics, and the supply network (pipeline option competitiveness vs. trucked in supply) to distribute hydrogen in a French region for automotive applications. Technical and economical issues, as well as GHG emissions, are addressed.

However, such a market is not expected in the short term. In the meantime, hydrogen may also contribute to reduce carbon emissions in diverse sectors: oil refining, low carbon mobility through the industrial deployment of advanced biofuels, natural gas consumption, and methanol production. According to the targeted market, objective costs are rather different; and so is the reachable mitigated CO 2 amount. This paper assesses the dynamics of these markets' attractiveness, in order to provide target costs for CO 2-free hydrogen production. The potential of the markets of hydrogen as a fuel and hydrogen for the biomass-to-liquid production is highlighted, as they could represent significant volumes by 2050, as well as interesting perspectives for CO 2 emission reduction. However the targets are very sensitive to the CO 2 price, thus highlighting the requirement for economic instruments in order to facilitate the penetration of such technologies. Hydrogen is then highlighted as a key player of the energy system in the years to come, as the connection of the energy and mobility sectors.
