Since the 1970s, during the oil crises, the primary focus was on increasing self-sufficiency with respect to energy sources. Current carbon economy becomes impractical due to increasing demand and resources reduction. Environmental concerns had taken the forefront, leading to a new phase in the field of energy development. That is why development of hydrogen technologies are getting perhaps more relevant than ever before. For our corporate client who is developing solutions in the field of alternative energy, hydrogen production and storage in particular, we identified technologies state-of-art, main technological trends, promising technologies in their field of interest, key opportunities and risks for development. In addition, we provided examples of existing market solutions, patents and technological focus of companies that offer these solutions. The resulting information allows comparing and assessing strategic changes in the technological environment, assessing the direction of inventive effort and the patent situation in selected technological areas.
