Abstract

Hydrogen technology has advanced significantly in recent years, making it a promising future energy source. It is, in fact, a clean, safe, and valuable fuel, offering a solution to renewable energy intermittency and redirecting energy for various applications. Since hydrogen technologies can potentially represent the energy of the future, understanding the determinants facilitating innovation is of paramount relevance. This study aims at understanding the determinants of hydrogen technology innovation across EU member states. Three sets of determinants are considered: human capital (Stock of graduates), institutional quality (Size of Government, Legal System and Property Rights, Sound Money, Freedom to Trade Internationally, Regulation), and sustainability endorsement (Hydrogen public R&D, Sustainable competiveness index). From a methodological perspective, a panel model comprising 27 EU member states is used. The final dataset consists of 540 observations from 1998 to 2019. Of the three sets of determinants, our results show that investment in human capital, the legal system, property rights protection, and investment in R&D activities could support the development of hydrogen technologies.

氢创新：探索其在欧洲的决定因素

近年来，氢能技术取得了显著的进步，使其成为一种有前景的未来能源。事实上，它是一种清洁、安全、有价值的燃料，为可再生能源的间歇性提供了解决方案，并为各种应用重新定向能源。由于氢技术可能代表未来的能源，因此了解促进创新的决定因素至关重要。本研究旨在了解欧盟成员国氢技术创新的决定因素。考虑了三组决定因素：人力资本（毕业生存量）、制度质量（政府规模、法律制度和产权、健全货币、国际贸易自由、监管）和可持续性认可（氢公共研发、可持续竞争力指数）。从方法论的角度来看，使用了一个由27个欧盟成员国组成的面板模型。最终的数据集包括1998年至2019年的540次观测。在三组决定因素中，我们的研究结果表明，人力资本投资、法律制度投资、产权保护投资和研发活动投资可以支持氢技术的发展。

期刊介绍： Energy policy is the manner in which a given entity (often governmental) has decided to address issues of energy development including energy conversion, distribution and use as well as reduction of greenhouse gas emissions in order to contribute to climate change mitigation. The attributes of energy policy may include legislation, international treaties, incentives to investment, guidelines for energy conservation, taxation and other public policy techniques. Energy policy is closely related to climate change policy because totalled worldwide the energy sector emits more greenhouse gas than other sectors.
