Challenges and Risks in Liquefying Hydrogen
According to an article posted in NRDC, liquefying hydrogen is challenging and costly. It portrays that
- It requires chilling it to a hyper-cold -253 degrees Celsius. That’s closer to temperatures found in outer space.
- The process requires significantly more energy than liquefying fossil gas
- Hydrogen has lower liquid energy density than LNG , meaning that for every LNG ship, approximately 2.4 LH2 ships would be needed to deliver the same amount of energy. This adds cost and energy intensity to the shipping process.
