The Case for Bioenergy

The Promise of Bioenergy

Bioenergy offers a reliable, dispatchable energy source, crucial for balancing the intermittent nature of solar and wind power. It is essential to emphasize that the scenarios we discuss in the report do not hinge on cultivating energy crops, which can often lead to deforestation or water overuse. Instead, our focus is on technological advancements that enhance the conversion efficiency of existing waste and residual biomass.

This strategic shift not only mitigates potential environmental repercussions but also leverages waste streams to generate energy, thereby promoting a circular economy. Germany, for instance, is poised to see a substantial increase in electricity demand, expected to rise from 590 TWh today to over 1000 TWh by 2045 due to increased electrification across sectors. To meet this burgeoning demand, while curtailing carbon emissions, a robust expansion of renewable energy, complemented by bioenergy solutions, is indispensable.

Technological Innovations Driving Change

The core of our argument in the report is anchored in the technological enhancements within the bioenergy sector, particularly through improved anaerobic digestion processes. These innovations promise to increase the yield and efficiency of biogas production, making bioenergy not only a sustainable choice but also a cost-effective one.

In the German context, the incorporation of at least 10 GW of hydrogen-ready gas power plant capacity underscores the country’s commitment to flexible power solutions, with biomethane playing a pivotal role. The dual benefit of this approach is the utilization of existing gas grid infrastructure, which can be adapted to distribute biomethane, thereby avoiding the high costs and extended timelines associated with building new infrastructure suited for hydrogen.

Economic and Environmental Implications

The transition to bioenergy can significantly reduce Germany’s dependency on energy imports, a vulnerability starkly highlighted during the European energy crisis following geopolitical upheavals. By enhancing domestic bioenergy production, not only is energy security bolstered, but also the resilience of the energy supply against price fluctuations and external shocks.

Moreover, the transition to bioenergy is estimated to reduce the overall investment needed to meet Germany’s renewable energy targets. With bioenergies added to the energy mix, projected investments could decrease significantly, providing economic relief while achieving environmental goals.

Key Figures and Future Outlook

• Energy Demand Growth: Electricity demand in Germany is expected to rise from 590 TWh to 750–1200 TWh by 2045.
• Efficiency Gains: Biomethane prices will come down from today’s €170-€190 Mw/h to €75-€85 MW/h.
• Investment Reduction: Transitioning to bioenergy can reduce the required investments from approximately 700–850 billion Euros to 550–700 billion Euros by 2035, saving up to 300 billion Euros. This results in 70.000 windmills less required.
• Production Potential: By improving the efficiency of anaerobic digestion processes, the potential bioenergy production could reach 130 TWh by 2030 and 195 TWh by 2050.

In conclusion, bioenergy, powered by technological innovations and not reliant on energy crop cultivation, offers a viable and strategic complement to other renewable sources in Europe’s energy transition. It promises enhanced energy security, economic savings, and a sustainable pathway to achieving net-zero emissions by 2050. As Europe continues to navigate its energy transition, bioenergy stands out as a key player in the diversified energy portfolio required to meet future demands sustainably and reliably.
