Summary: To achieve low-carbon electricity transition, carbon capture, utilization, and storage (CCUS) and battery energy storage system (BESS) are promising tools for overcoming high carbon intensity and fluctuating output. The potential of these technologies in carbon trading was analyzed and compared using real option approach. The study found that the positive effect of carbon trading on CCUS adoption was more significant than that of BESS. Electricity marketization can promote the utilization of CCUS and BESS by increasing potential revenue from selling electricity and emission quotas.

Summary: The study shows that the Central Western Europe power system can achieve decarbonization targets at both 2 degrees C and 1.5 degrees C, while providing reliable low-carbon electricity. However, the system costs for the 1.5 degrees C scenario are found to be twice as high as those for the 2 degrees C scenario, primarily due to the high cost of negative emission technologies such as direct air carbon capture (DAC).

Summary: Biomass use for energy and materials is a key mitigation option to reach the 1.5 degrees C global temperature target set in the Paris Agreement. However, negative connotations have emerged in certain parts of the EU, particularly regarding displacement effects in markets and land use. Despite this, strong evidence supports the use of sustainable biomass, and there are insights on how to avoid displacement issues. By utilizing better agricultural methods, restoring marginal and degraded lands, and adapting to climate change, biomass can contribute significantly to the future energy and material supply, with potential benefits for overall mitigation and the removal of CO2 from the atmosphere. It is recommended that future policies prioritize the synergy between biomass, energy transition, climate adaptation, agriculture, and land use, as this offers an opportunity to contribute to the European Green Deal and improve energy security.

Summary: In power system studies, the unit commitment problem is solved to support market decisions and assess system adequacy. The impacts of simplifications on solution quality and computation time were thoroughly investigated, revealing that some simplifications led to significant quality loss without reducing computation time. However, the linear relaxation approach resulted in less quality loss with a significant speed-up, and no difference when unserved energy was minimized. Both the average and maximum capacity factor difference were found to be large for all model variants.
