The Bulgarian Natural Gas Association (BAPG) is embarking on an innovative project to produce green hydrogen and mix it into the gas grid, positioning hydrogen as a solution to utilize excess renewable electricity. The plan involves decentralized production and distribution, with traders purchasing cheap renewable electricity for electrolysis. While challenges exist in the competitiveness of green hydrogen as a heating fuel or transportation energy source, its role in managing surplus renewable power is crucial. Countries like Germany and the Netherlands are leading this transition by repurposing their gas networks to support 100% hydrogen infrastructure. BAPG's initiative focuses on leveraging existing distribution networks and polyethylene pipes to introduce hydrogen blends, with successful tests showing household appliances can operate with up to 35% hydrogen.
