The eighth Trialog in cooperation with the academy project "Energy Systems of the Future" dealt with questions of a sustainable bioenergy strategy. Nearly 60 participants spent a day discussing the potential that the use of biomass for energy has for the energy transition and climate protection.

Bioenergy has many uses: as a biofuel in transport, for heating as well as for electricity generation. Another option is to capture carbon dioxide from biofuel production plants or biomass power plants and store it underground (BECCS). Since the stored carbon dioxide was previously absorbed from the atmosphere by plants, "negative emissions" result. Global climate change scenarios indicate that climate change targets are not achievable without such negative emissions. However, biomass cultivation can produce greenhouse gas emissions that reduce climate benefits. In addition, as a limited resource, biomass is used not only for energy supply, but also in the food and feed industries. If energy crops are not grown sustainably, they can also pollute the environment, soil and water.
