Decarbonizing the economy and achieving the transition from fossil fuels to renewable energies is one of the most urgent global challenges of the 21st century. Hydrogen can play a key role in this process as a promising climate-neutral energy vehicle. Yet, the so-called green hydrogen economy requires that hydrogen production be based exclusively on renewable energy. In addition, it should ideally not use expensive and rare metal catalysts, whose production has severe environmental consequences. To address this challenge, ITQB NOVA researchers Inês Cardoso Pereira and Mónica Martins are working on an innovative technology to produce hydrogen from light using non-photosynthetic microorganisms.
