Hydrogen's Role in Achieving Net Zero: A Journey to Decarbonization

This presentation commences with an introduction to Enertek International Ltd., a research and development consultancy based in the UK. It underscores the remarkable journey of the UK in embracing hydrogen as an energy source, commencing with the pivotal H21 Leeds City Gate Project, which explored the conversion of the gas grid to 100% hydrogen. The success of demonstrations involving hydrogen-fired appliances and commercial equipment paves the way for large-scale initiatives, including the pioneering world's first green hydrogen network, set to provide hydrogen infrastructure thousands in UK.
The presentation highlights the UK's commitment to clean energy, marked by legislative milestones and the UK's comprehensive hydrogen strategy. It emphasizes the vital role hydrogen plays in the ongoing energy transition.
The audience is then guided through the potential of hydrogen blending to expedite short-term decarbonization by harnessing existing gas infrastructure. The roadmap to ensuring safe utilization of appliances with up to 20% hydrogen-enriched natural gas is outlined, as well as the path to achieving full-scale adoption of 100% hydrogen.
The international perspective is explored, with insights into
North America's hydrogen strategies are explored and a comparison of energy consumption in the U.S. and the UK is addressed. The presentation underscores the significance of energy diversity in bolstering reliability, security, and the rapid mitigation of climate change impacts. Finally, the audience gains an overview of the diverse array of tools available for decarbonization in the global energy landscape.
