[en] An assortment of governmental, technological, environmental, and economic factors has combined to spur renewed interest in alternatives to petroleum, and especially in hydrogen. While there is no clear consensus on the viability of the technology, governments and corporations alike have vigorous hydrogen research programs. The result is that hydrogen may stand on the verge of becoming a true successor to oil. A transition from oil to hydrogen would alter familiar global economic and political structures in profound ways. The ramifications will influence developed and developing nations, oil importers, and exporters alike. New alliances among governments, corporations, and other groups may challenge existing notions of governance. Although a hydrogen-based economy may be decades away, the vision for it requires near- and mid-term thinking to manage the transition smoothly. Further, hydrogen is only a metaphor; any change from the current oil economy will entail dramatic changes to the global status quo that must be planned for now

[en] Highlights: • We present a novel method to assess the exposure to physical asset stranding risks. • We capture the propagation of stranding risks via international production networks. • We calculate supply-side fossil ‘stranding multipliers’ for 43 countries and 56 sectors. • Fossil-triggered stranding risks are significant and affect also downstream sectors. • USA and China are the most exposed economies to global fossil stranding risk. A timely low-carbon transition will require a significant decline in fossil fuel production and consumption. This in turn exposes the rest of economic sectors to the risk of reduced usability of physical capital stocks via international production network linkages. We propose and apply a simple measure to assess the extent to which fossil shocks might trigger underutilisation of capital stocks across countries and productive sectors (‘stranding multipliers’). Our results highlight the relevance of supply-side transition risks. First, among all productive activities, the global fossil sector exhibits the highest stranding multiplier on the rest of the economic system. Second, some of the most exposed sectors are downstream activities, mainly affected by second-round effects. Third, we rank countries according to their external stranding potential, finding France, Australia and Slovakia at the top, and the USA, Italy and China at its bottom. Finally, we rank countries according to their exposure to stranding risk and analyse more in depth the origins and transmission channels of the stranding links affecting some of the most exposed countries (USA, China and Germany).

[en] As far as innovative energy systems go, hydrogen raises very high expectations. Using Google(R) as a yardstick for interest, one finds out that the phrase 'hydrogen economy' generates around 212,000 references. This is less than nuclear fusion (330,000) but much more than 'clean coal' (less than 44,000). This very abundance of information does not help communicators to shape their own opinion with respect to the role of hydrogen in future energy systems. This paper attempts to provide a summary of the most important facts to be borne into mind

[en] In this work we have developed a technical and economical study for the stablishment of a industrial gamma irradiation facility in Ecuador. This facility would have a multiple use, it could be used in two principal fields: sterilization of disposable medical supplies and food preservation. The technical study is related with the desing of the irradiator source and the calculation of shielding walls and the selection of same important equipments. The economical study foresees a useful life of ten years in ral values and actual values related to the year of installation wich is considered the initial year

[en] Green Building Councils (GBCs) have been established in many different countries in recent years. This paper discusses the role such organizations can play in the respective construction and real estate industry and under what circumstances a GBC can contribute positively to the development of a “greener” or “more sustainable” stock of buildings. The paper investigates the main informational problem of the industry by looking at the relation between a developer and an investor from an economic point of view. We argue that the investor's uncertainty about the true quality of a building and the corresponding incentive for the developer to cheat may lock them into a prisoners' dilemma trap. The corresponding barriers for a transition toward a “greener” buildings market are analyzed. GBCs are described as institutions of economic governance that can assist the economy in overcoming these problems. They can act as third party institutions in transactions between developers and investors. By certifying the quality of a building, they can reduce the risk for the investor to be cheated by the developer and also increase the incentive to develop good quality buildings for the developer. This task, however, raises some severe management challenges for the GBCs. - Highlights: ► We focus on Green Building Councils and their economic role. ► The paper investigates the informational problem of the sustainable building market. ► Developers and investors are locked in a prisoner's dilemma. ► Can the councils act as third party institutions to certify quality of buildings? ► Credibility and reliability are key features for third party certification.

[en] Highlights: • Frequency spillovers among oil, gold and foreign exchange markets are investigated. • Total spillovers are higher in the short-run compared to the long-run. • Higher spillovers during the European debt crisis and the COVID-19 pandemic. • Gold and oil are net risk receivers with strong “short-term vulnerability”. • Foreign exchange markets of advanced economies are dominant risk transmitters. Utilising the time-frequency spillover framework constructed by Baruník and Křehlík (2018), this study explores the time-frequency risk spillovers among the oil, gold and foreign exchange (FX) markets using implied volatility indices. The results indicate that total spillovers are higher in the short term than in the long term. The impact of FX markets on oil and gold markets is greater than the reverse impact, and the FX markets of advanced economies are the main drivers. The results for the spillover network show that the short-term risk spillover effects are stronger during the European debt crisis and the COVID-19 pandemic. The euro, Australian dollar, and Canadian dollar are dominant risk transmitters during the crisis, and gold and oil are net risk receivers with high short-term vulnerability. Our results have significant implications for risk managers and portfolio managers at different investment horizons.

[en] This presentation outlines the steps in integrating of hydrogen into Canada's energy future. Canada's hydrogen and fuel cell investment is primarily driven by two government commitments - climate change commitments and innovation leadership commitments. Canada's leading hydrogen and fuel cell industry is viewed as a long-term player in meeting the above commitments. A hydrogen and fuel cell national strategy is being jointly developed to create 'Win-Wins' with industry
