Our Projects
Together with our sister organization atmosfair gGmbH, we develop climate protection projects around the world. Our focus lies on countries of the Global South, combining climate action with improvements in the living conditions of people who are most affected by climate change. Solarbelt focuses on projects for the production of sustainable fuels for the aviation and maritime sectors. We carefully assess which technology is best suited for each region. If a country already has sufficient access to renewable electricity - such as Kenya, Ethiopia, or Brazil - a Power-to-Liquid technology pathway may be appropriate, as it does not compromise the sustainable electricity supply for the local population. In countries with sufficient amounts of sustainable residual biomass - such as Indonesia - but where electricity generation still relies heavily on fossil fuels, we instead focus on biomass-based Biomass-to-Liquid technologies.
Together with our local partners, we develop business models that are not only climate-friendly, but also generate additional income opportunities for local communities and businesses.

Power-to-Liquid
Power-to-Liquid (PtL) technology produces nearly climate-neutral liquid fuels such as synthetic kerosene from renewable electricity and CO₂. Despite high costs and energy-intensive processes, PtL is considered one of the most promising solutions for replacing fossil fuels and significantly reducing emissions, particularly in the aviation sector. As a pioneer in the field, Solarbelt was involved in the development of one of the world’s first plants for the production of PtL fuels and is currently working intensively on projects focused on the production of e-methanol.
Biomass-to-Liquid
Biomass-to-Liquid (BtL) technology converts solid residual biomass such as wood residues, cashew shells, or coconut shells into sustainable liquid fuels - with little to no additional electricity demand. Despite currently high production costs, we have successfully demonstrated the technical feasibility of producing synthetic kerosene from real residual feedstocks. We believe BtL holds great potential to create new local value chains in the Global South while supporting the sustainable decarbonization of the transport sector.
Power- and Biogas-to-Liquid
The Power- and Biogas-to-Liquid (PBtL) pathway converts biogas derived from residual and waste biomass into synthesis gas through reforming or plasmalysis, and subsequently into sustainable fuels - with significantly lower electricity demand than conventional PtL processes. PBtL can also utilize wet biomass feedstocks and creates additional value through the use of waste materials. However, since biogas is already a valuable resource, the implementation of PBtL requires careful consideration of local biogas utilization options.
