Green hydrogen will be an essential part of the future 100% sustainable energy and industry system. Up to one-third of the required solar and wind electricity would eventually be used for water electrolysis to produce hydrogen, increasing the cumulative electrolyzer capacity to about 17 TWel by 2050. The key method applied in this research is a learning curve approach for the key technologies, i.e., solar photovoltaics (PV) and water electrolyzers, and levelized cost of hydrogen (LCOH). Sensitivities for the hydrogen demand and various input parameters are considered. Electrolyzer capital expenditure (CAPEX) for a large utility-scale system is expected to decrease from the current 400 €/kWel to 240 €/kWel by 2030 and to 80 €/kWel by 2050. With the continuing solar PV cost decrease, this will lead to an LCOH decrease from the current 31–81 €/MWhH2,LHV (1.0–2.7 €/kgH2) to 20–54 €/MWhH2,LHV (0.7–1.8 €/kgH2) by 2030 and 10–27 €/MWhH2,LHV (0.3–0.9 €/kgH2) by 2050, depending on the location. The share of PV electricity cost in the LCOH will increase from the current 63% to 74% by 2050. ; This study was made under the framework of the European Technology and Innovation Platform for Photovoltaics (ETIP PV).

"This book analyzes the constraints on press freedom and the ways in which independent reporting and reporters are at risk in contemporary Asia to provide a barometer of democratic development in the region. Based on in-depth country case studies written by academics and journalists, and some who straddle both professions, from across the region, this book explores the roles of mainstream and online media, and how they are subject to abuse by the state and vested interests. Specific country chapters provide up-to-date information on Bangladesh, Kashmir, Malaysia, Myanmar, Nepal, Pakistan, Sri Lanka, Taiwan, Thailand and Vietnam, as well as on growing populist and nationalist challenges to media freedom in the Philippines, India, Indonesia and Japan. The book includes a theoretical chapter pulling together trends and common constraints facing newsrooms across Asia and a regional overview on the impact of social media. Three chapters on China provide insights into the country's tightening information environment under President Xi Jinping. Moreover, the legal environment of the media, political and external pressures, economic considerations, audience support and journalists' standards and ethics are explored. As an international and interdisciplinary study, this book will appeal to undergraduates, graduates and scholars engaged in human rights, media studies, democratization, authoritarianism and Asian Studies, as well as Asia specialists, journalists, legal scholars, historians and political scientists"--
