Article Synopsis
- The European Union is working towards climate neutrality by 2050, highlighting the need to explore greenhouse gas reduction and carbon dioxide removal strategies from a comprehensive life cycle perspective of buildings.
- This study identifies and categorizes 35 measures under 11 carbon removal strategies, analyzing their impact and feasibility across various EU Member States.
- Short-term gains in reducing greenhouse gas emissions can be achieved by improving energy use, using low-carbon materials, and managing space efficiently, while long-term strategies like promoting circularity and renovation are expected to gain traction as supply chains and skill sets evolve.
The challenging problem of ultra-high-energy-density, high-efficiency, and small-scale portable power generation is addressed here using a distinctive thermophotovoltaic energy conversion mechanism and chip-based system design, which we name the microthermophotovoltaic (μTPV) generator. The approach is predicted to be capable of up to 32% efficient heat-to-electricity conversion within a millimeter-scale form factor. Although considerable technological barriers need to be overcome to reach full performance, we have performed a robust experimental demonstration that validates the theoretical framework and the key system components.

Photonic crystals (PhC) have the potential to strongly suppress such losses. However, PhC-based designs present a set of non-convex optimization problems requiring efficient objective function evaluation and global optimization algorithms.
