Accelerating U.S. Clean Energy Deployment: Investor Policy Priorities [PDF]
, 2015 International investment to mitigate climate change is far below levels needed to reach the two-degree target. The International Energy Agency estimates that an average of an additional $1 trillion in incremental financing for clean energy is needed to ...

, 2021 Hydrogen (H2) was identified as a potential solution to have a clean fuel in the future. Hydrogen has characteristics that give it Properties to be a renewable element capable of providing safe energy, economically competitive and free of carbon dioxide (CO2) emissions. In this work we study how to obtain energy from hydrogen.

Residual Stress States in Microstructurally Graded PBF–LB/M Austenitic Steel Components
Advanced Engineering Materials, EarlyView.This study examines microstructurally graded 316L rectangular tube profiles fabricated via PBF–LB/M using a dual‐laser system. A 1 kW top‐hat and a 400 W Gaussian laser create distinct grain sizes and crystallographic texture. Mechanical properties are linked to microstructural evolution driven by processing conditions.
