Professor Dominique Mouette from USP discusses various sustainable technologies beyond electric vehicles for decarbonizing the automotive sector. Despite the advantages of electric vehicles, challenges like high costs and infrastructure limitations exist. Hybrid cars with self-recharging batteries offer a solution by utilizing energy from braking. Other technologies like biomethane, biodiesel, synthetic fuels, and green hydrogen are being researched for their potential in sustainability. Biomethane, derived from sugarcane and waste, is highlighted for its decentralized production and environmental benefits. However, green hydrogen, though promising, requires further development due to energy-intensive production. Dominique emphasizes the importance of government incentives like RenovaBio to spur the production of renewable fuels. Diversification of energy sources, including electricity, biomethane, and hydrogen, is crucial for energy security and reducing dependence on external markets.
