Marcelo Miguel, a former electrical engineer at Itaipu, embarked on a new journey in Foz do Iguaçu by delving into hydrogen energy generation after his retirement. His career transition into this field not only kept him engaged but also highlighted the growing importance of hydrogen as a sustainable energy source domestically and globally. With a focus on clean energy solutions amid concerns of global warming, hydrogen stands out as a carbon-free fuel, positioning it as a crucial element for a sustainable future. Foz do Iguaçu, notably through the PTI, has been actively involved in hydrogen production since 2014, utilizing a combination of solar panels and energy from Itaipu to drive this initiative. Marcelo envisions Brazil playing a significant role in hydrogen production and distribution, citing its potential as a cleaner energy alternative for various sectors, including transportation. Furthermore, Marcelo points out the international shift towards hydrogen, especially in Europe following concerns over gas supply disruptions due to the conflict in Ukraine. He emphasizes the versatility of hydrogen production, noting its independence from traditional transportation limitations like oil, as observed in the United States where solar-powered hydrogen stations are already operational. As Marcelo advances in his studies on Energy and Sustainability, particularly focusing on hydrogen, his expertise as an advisor to the Brazilian Hydrogen Association and consultant for key energy organizations showcases the growing interest and investment in hydrogen as a key component of the future energy landscape. Through his insights and involvement, Marcelo underscores the transformative potential of hydrogen in advancing sustainability goals and driving clean energy innovation.
