Green hydrogen potential as a clean energy carrier presents promising prospects in the fight against climate change. The most efficient method of producing decarbonized hydrogen is through electrolysis, which involves splitting water molecules using renewable sources of electricity. Morocco boasts various advantages that enable it to play a pivotal role in bringing this vision to fruition. Lately, the nation has devised an ambitious strategy for green hydrogen and implemented significant changes related to industry and water resource management. This document presents a thorough examination of Morocco's energy sector, with a special focus on the substantial hurdles that must be surmounted to establish an economy centered on green hydrogen, with the capacity to generate employment opportunities and achieve carbon neutrality. Numerous impediments require cooperation with Europe and other international allies to establish a green hydrogen industry in Morocco. These challenges encompass bolstering the competitiveness of green hydrogen, scaling up production, and cultivating the requisite expertise. • Morocco is identified as one of the countries with the highest potential for green hydrogen export. • Green hydrogen roadmap for Morocco is presented and analyzed. • Technological, economical, environmental and societal challenges for green hydrogen development in Morocco are outlined.

In order to achieve the goal of a carbon neutral EU by 2050 and meet the climate targets of the Paris Agreement, a sustainable, efficient, competitive and secure energy system needs to be developed. This paper presents the synthesis of sustainable renewable energy supply networks within the EU-27, proposing a stepwise energy transition in the transport and power sectors, achieving a carbon net neutral target by 2050. A multi-period mixed-integer programming model is developed, with the objective of maximizing sustainability net present value, considering different biomass and waste resources for the production of biofuels, renewable electricity, hydrogen, food and bioproducts, employing different types of technologies. The results show that, with further development of existing technologies, the goal of a carbon-neutral EU can be achieved without compromising food production. Wind farms have proven to be the most promising solution at present for the rapid expansion of electricity generation from renewable energy sources, while the importance of solar photovoltaics is increasing over the years, reaching the 43% share of electricity generation from RES in 2050. Moreover, the energy transition within the EU could have a significant positive impact on the economic, environmental and also social aspects of sustainability, with more than 1.5 million new job opportunities created across the EU over the next 30 years.
