360-degree solutions for renewable energy


Our THINK business unit develops innovative and integrated concepts for renewable energy projects powered by solar and wind energy as well as biogas plants.
GP JOULE focuses on local and district heating as well as the production, use and distribution of green hydrogen. We support companies, municipalities – mostly with between 500 and 10,000 residents – and investors in the preparation, realisation and ongoing support of their projects. After all: everyone has the energy to make a difference. 

Expertise for all sub-sectors of renewable energy

Our aim is join forces with you to drive forward the energy turnaround. Our experts provide you with their know-how in all areas of renewable energy: project planning, design, construction of your plant – under EPC contracts also as a general contractor – and the subsequent processing and marketing of the hydrogen produced.

Innovative pioneering project eFarm

As a driving force and an expert in the field of cross-sector linkage, we have successfully put this into practice with our innovative hydrogen mobility project eFarm. The latter covers the entire value chain of renewable energy – and our full range of services, too. Green hydrogen is at the heart of the eFarm project: it is the link between sustainable energy production from solar and wind power on the one hand and other sectors on the other such as heat supply and mobility, including hydrogen distribution at two specially installed H2 filling stations.

With our practical knowledge, we support companies and local authorities in taking the future of local energy supply into their own hands and providing important stimuli for the regional economy. The aim is to introduce a sustainable, collective system to society at large based on renewable energy.
