The fossil fuel economy at present has led to climate change that threatens the very existence of humankind. The hydrogen economy that is based on renewable energy is expected to enable a sustainable, de-carbonized, and circular economy. In this webinar, the technical and economic background on the generation, storage, transportation, and use of hydrogen is presented. The potential impact on power generation, chemical production, transportation, and heating for buildings is highlighted. However, there are numerous hurdles in realizing the hydrogen economy. Some of the innovations and technical developments in progress, and thus the related business opportunities and growth, are discussed. The webinar is followed by a panel discussion of selected technologies/issues in more detail.
