The article highlights the importance of transforming existing infrastructure towards sustainable solutions to meet the global push for renewable energy sources like green hydrogen. With a focus on decarbonisation, the energy crisis due to geopolitical events underscores the need for energy security through investments in green technologies. Initiatives in the transport sector, such as battery-powered trains in Germany, demonstrate tangible emissions reductions. To achieve climate neutrality goals, countries need to invest in infrastructure for producing green gases and electricity, including green hydrogen. The growing global energy consumption necessitates significant grid investments to accommodate new forms of power generation, like solar and wind farms. Projects like the NeuConnect interconnector between Germany and the UK are examples of infrastructure developments supported by private capital sources. Overall, a comprehensive energy transition with a focus on modernizing infrastructure and investing in green technologies is essential for a resilient and sustainable future.
