Abstract
To combat global climate change caused by CO₂ emissions, achieving net-zero emissions through sustainable energy solutions is a global priority. Among alternative energy carriers, hydrogen is a promising renewable energy source due to its efficiency in production, transportation, and storage. Liquefied hydrogen (LH₂) transportation is gaining attention as it significantly..... More

Abstract
Generally, molds are fabricated by the machining of massive billets of tool steels, such as AISI4140 or H13, but it has drawbacks, such as a large material loss and long-delivery time. The Wire-Arc Additive Manufacturing (WAAM) process could be an alternative fabrication method. It has the advantages of less material..... More
