Problems solved by technology

And in the coastal areas and other places in low-latitude areas, there will be many ports for transporting and storing LNG. These ports generally use seawater to heat up LNG and convert it into NG (natural gas) for outward transportation. The cold energy is wasted, and the discharge of cold energy It will have a great impact on the surrounding seawater ecological environment
