Résumé

In 2018, global energy consumption increased by 2.3%, almost twice the average growth rate since 2010. More than half of the increase in energy needs was due to an increase in electricity demand. As a result, CO2 emissions rose by 1.7% and hit a new record (IEA, 2019). In order to reduce CO2 emissions, renewable energy sources are being increasingly integrated into the production mix. Given that these sources are intermittent and variable, their integration creates supply and demand balance issues in the energy market. A possible solution is to store the produced energy as hydrogen. When renewable energy sources are in plentiful supply, the energy produced can be converted into and stored as hydrogengas. The hydrogen canthen be reconverted into electricity using a fuel cell for households’electricity needs, or can it can be blended with natural gas and distributed to households for gas heating. This hydrogen conversion and storage can take place at different levelsof decentralisation and can be controlled by different actors (local energy communities, private, or public actors). Currently, consumer knowledge of hydrogen as an energy carrier is limited,includingin areas with existing demonstration projects and hydrogen distribution networks (Flynn et al. 2012; Zaunbrecher et al., 2016). Despite a low level of knowledge, focus groups find that support for hydrogen energy technologies is positive (Ricci et al., 2008; Achterberg et al., 2010). Support for hydrogen energy technologies is particularly affected by monetary and environmental costs, safety and risk of the technology, consumer trust in the actors behind the technology, and who benefits from the technology (Roche et al., 2010; Flynn et al., 2012; Ambrosio-Albara et al., 2019). We use adiscretechoice experiment (Train, 2009) to analyse consumer preferences for differentdelivery methods of hydrogen energy (converted into electricity, delivered via gas pipelines), the proximityof storage systems, whether community, public or private actors control the system, the level of energy self-sufficiency provided by the system, and the monetary cost to the consumer.In order to determine how the framing of hydrogen energy storage benefits influence consumer preferences for such systems, we run 3 treatments in which the principal benefits of a hydrogen energy storage system are presented as either for the household, for the grid, or for the environment. The results of each of these treatments are compared to a control group in which no specific benefits of hydrogen energy storage systems are presented. In addition, we control for other factors affecting preferences for hydrogen technologies, and new technologies in general, through a psychological questionnaire including questions on trust, perceived risk,and pro-environmental behaviour.
