As the offshore energy sector shifts from fossil fuels to renewable sources, repurposing aging oil and gas platforms offers a sustainable alternative to decommissioning. In a new study published in Applied Ocean Research, we assess the structural performance of such repurposed platforms for offshore wind energy generation. Using OpenFAST time-domain simulations, we estimate fatigue damage under nine representative sea states and identify critical stress points on the platform. Results show that lower-leg components are most vulnerable, particularly under high wind conditions that induce resonant responses. These findings inform future strategies for structural retrofitting and reuse planning in offshore wind deployment. https://doi.org/10.1016/j.apor.2025.104696

Grid-interactive energy systems with multiple co-products offer promising pathways for decarbonization, but their operational complexity poses significant modeling challenges. In a new study published in Computers and Chemical Engineering, we introduce a scalable computational framework for optimizing the integrated design and scheduling of such systems over 8,760 hours of annual operation. Applying the framework to a nuclear power plant coupled with high-temperature steam electrolysis (HTSE), we show that co-production can be economically competitive with standalone HTSE. Sensitivity analyses further highlight that early R&D efforts should focus on increasing current density to 3–4 A/cm² to improve economic feasibility. https://doi.org/10.1016/j.compchemeng.2025.109213
