Aviation's environmental footprint extends beyond just CO2. Non-CO2 effects like nitrogen oxide emissions and contrails also significantly influence climate change. Although contrails may seem minor, their cumulative warming effect could notably contribute to global warming by 2050. Understanding and mitigating this impact is essential for a more sustainable aviation future. Collaborative Efforts to Reduce Contrail Impact Several airlines are testing flight rerouting strategies to

Reuniwatt, specialist in cloud-cover prediction and solar irradiance forecasting, is taking part in the SOLiS project. Leveraging its expertise in cloud prediction, the company contributes to advancing satellite-based optical communications — a key technology for achieving ultra-fast, secure data transfer between Earth and space. Our work was presented in a recent article by Bernard Grollier in Les Echos published on July 17, 2025. Here

Reuniwatt, a leader in cloud observation and solar irradiance estimation and forecasts, marks its 15th anniversary. The company's flagship product, the infrared all-sky imager Sky InSight™, continues to revolutionize renewable energy and atmospheric sciences alike. Reuniwatt, a pioneer in cloud observation and solar irradiance forecasting, proudly celebrates its 15th anniversary, marking a significant milestone in its journey towards empowering the renewable energy transition. Since

EO4ER (“Earth Observation for Energy Risks”) has been selected by ESA in the context of the Destination Earth (DestinE) flagship initiative, to develop a Digital Twin Component prototype for the energy sector. EO4ER’s consortium is composed of IT and cutting-edge software development specialist OHB Digital Services, THU’s application-orientated Smart Grids Research Group and cloud estimation and forecasting expert Reuniwatt. Reuniwatt, OHB Digital Services and

More and more mining companies are installing solar panels on their own sites to generate clean energy for their operations. If there is a grid connection, they can partner with solar energy providers to purchase solar energy from external sources and use it in their operations. Fekola Mine is one such flagship project of Reuniwatt, and in the mining industry in general. Solar energy

The images provided by Reuniwatt's sky imagers are an outstanding tool for cloud-related research. Forecasting the impact of condensation trails – so-called contrails – is one goal our sky imagers help to achieve.  Different research projects aim to provide tools to monitor the climate impact of contrails and forecast contrail formation. Learn more about contrails observation using sky imagers and the R&D projects featuring

Trust-PV is a four-year, EU-funded project featuring 21 PV value chain partners who aim to improve the performance of solar projects. French business Reuniwatt has published the ‘Forecasting for advanced operational stability’ study to improve stability at the point of grid connection. Marion Lafuma, business development manager for Reuniwatt, looks at its key findings. Improving the accuracy of energy yield forecasts will help PV
