The researchers working in the project ZLE developed an “Open Science Declaration” committing their research activities to the standards of Open Science. Research within the ZLE will be built upon the idea of sharing scientific methods, data, and publications to improve research quality and make results accessible to the scientific and non-scientific communities. Members of the ZLE support the principles of Open Science as expressed by the Budapest Open Access Initiative, the Berlin Declaration, the Horizon 2020 Program, and the German Strategy for Open Access. Funded by the Ministry of Science and Culture of Lower Saxony, one of the major goals of the ZLE is to make energy research activities and its resources available for public use while preserving the intellectual property of all involved parties. This will strengthen the research in Lower Saxony by promotion and expansion of cooperation between science and industry on strategic sectors. Moreover, greater transparency in the use of public funds and in the development of research activities is enabled.
