Penspen, a UK-based company, has secured a hydrogen blending contract from Latvian natural gas operator Conexus Baltic Grid to evaluate the integration of hydrogen blends into Latvia's existing natural gas pipeline network. The project focuses on ensuring the structural integrity and safety of the network under blended conditions, aligning the infrastructure with global and national regulations. This initiative signifies a step towards a cleaner energy future in Latvia. The article also highlights the significance of hydrogen in the energy transition as a key focus of COP29. The Hydrogen Declaration, signed by global stakeholders, emphasizes the scaling up of renewable and low-carbon hydrogen production while moving away from fossil fuels. The COP29 Presidency has launched complementary energy initiatives such as the Global Energy Storage and Grids Pledge and the Green Energy Pledge to promote renewable energy accessibility and expansion of energy grids. Industry leaders have expressed strong support for these initiatives, with figures like Jorgo Chatzimarkakis, CEO of Hydrogen Europe, recognizing the historical importance of the Hydrogen Declaration. The urgency of energy storage and grid development was emphasized by IEA Director Fatih Birol, with IRENA Director-General Francesco La Camera advocating for these initiatives to maintain the path towards achieving climate goals.
