What is Green Hydrogen?

Before diving into the specifics of Southeast Asia, let's clarify what exactly we mean by green hydrogen. Hydrogen, the most abundant element in the universe, can be a clean energy carrier. However, not all hydrogen is created equal. The color assigned to hydrogen indicates its production method and associated environmental impact.

• Gray Hydrogen: Produced from natural gas through steam methane reforming (SMR), releasing significant amounts of carbon dioxide (CO2) into the atmosphere.
• Blue Hydrogen: Similar to gray hydrogen but with carbon capture and storage (CCS) technologies to reduce CO2 emissions.
• Green Hydrogen: Produced through the electrolysis of water, using renewable energy sources like solar or wind power. This process splits water (H2O) into hydrogen and oxygen, with minimal to no greenhouse gas emissions.

Green hydrogen stands out as the most environmentally friendly option, offering a pathway to decarbonize various sectors and achieve climate goals. It's the holy grail of hydrogen production, paving the way for a truly sustainable energy economy. Southeast Asia, with its abundant renewable energy resources, is well-positioned to capitalize on the potential of green hydrogen.
