The technology diffusion literature has extensively analysed drivers for and barriers to the adoption of renewable energy technologies. However, there are relatively few studies that analyse drivers and barriers from the perspective of renewable energy technology suppliers. An analysis of the supplier-side is complementary to demand-side studies as policy makers seek to stimulate the international diffusion of renewable energy technologies. The international diffusion of renewable energy technologies is necessary for countries to reach their often-ambitious targets regarding independence from fossil-based energy sources. Thus, the aim of this article is to analyse the drivers for and barriers to the international diffusion of renewable energy technologies from the perspective of technology suppliers. In doing so, a survey was conducted amongst 85 biogas technology suppliers in Sweden, with a 34% response rate. Using a one-way analysis of variance (ANOVA), we analysed differences between their perceived barriers and drivers in the international diffusion of biogas technologies through export. Our findings suggest the need for technology and market-specific export promotion initiatives to complement the generic initiatives available for all exporters and make them more effective.

技术传播文献已广泛分析了采用可再生能源技术的动因和障碍。但是，从可再生能源技术供应商的角度分析驱动因素和障碍的研究相对较少。当决策者寻求刺激可再生能源技术的国际传播时，对供应商方面的分析是对需求方研究的补充。可再生能源技术的国际传播对于各国实现独立于化石能源的雄心勃勃的目标是必不可少的。因此，本文的目的是从技术供应商的角度分析可再生能源技术国际传播的动因和障碍。在这样做，在瑞典的85家沼气技术供应商中进行了一项调查，答复率为34％。使用单向方差分析（ANOVA），我们分析了它们在出口沼气技术的国际传播中的感知障碍与驱动因素之间的差异。我们的发现表明，需要技术和针对特定市场的出口促进计划，以补充所有出口商可以使用的通用计划，并使它们更加有效。
