Climate change is an undeniable reality, caused by the consumption of carbon-based energy sources such as oil and coal. In the effort to transition to an energy matrix that can replace these carbon-intensive fuels and significantly reduce CO2 emissions, hydrogen has emerged as a highly viable, eco-friendly, and promising solution.
