Port-Adjacent Hydrogen Hub – Coming Q1 2026
Supplying hydrogen gas to fuel cells or internal combustion engines for power generation in vehicles and machinery. An environmentally-friendly option, Hydrogen is a clean energy source that produces only water vapor when burned or used in fuel cells. Even better, it has a high energy density, which makes it an efficient and powerful fuel option.
More efficient at removing heat than air, due to it’s exceptional heat transfer properties, leading to smaller and more efficient generator designs.
Hydrogen acts as a clean energy carrier, primarily used in fuel cells to produce electricity by combining hydrogen with oxygen, creating only water as a byproduct; it can be particularly valuable for storing renewable energy like solar and wind power when production exceeds demand, allowing for flexible grid management by storing excess electricity as hydrogen and releasing it when needed.
