In this episode of the Hydrogen Economist Podcast, Lee Nichols explores hydrogen's critical role in the global shift towards net-zero emissions. Over 70 countries aim to decarbonise sectors such as transport and power, with hydrogen at the forefront. With demand expected to hit 650 million tonnes by 2050, significant investment is needed in production and infrastructure. Nichols examines the surge in green and blue hydrogen projects, especially in Western Europe, Asia, and the US, and their impact on the shipping industry's move to lower emissions.
