Energie : papiers de recherche moissonnés (9/11/2017)

Renewable Energy for Industry / Cédric Philibert. Paris : IEA, Nov. 2017, 72 p. (IEA energy insight) https://www.iea.org/publications/insights/insightpublications/renewable-energy-for-industry.html

The rapid fall in cost of solar and wind power technologies opens a new range of possibilities to decarbonise the global economy and cut carbon emissions from industry. Besides direct renewable heat and electrification, hydrogen-rich chemicals that are easy to store and transport could serve as feedstock, process agents and fuels. They could be produced in areas with abundant and cheap resources, and shipped to consuming centers, opening the prospects to a new kind of international energy trade. This Insights Paper examines emerging technology options, and reviews national and international policies that could foster their development and their deployment.

The Future of Coal in India, Down To Earth, 2017 http://www.downtoearth.org.in/coverage/the-end-of-coal-58909

The article explains how the world is undergoing a massive energy transformation. We can appreciate and understand this transformation by reflecting on some of the trends emerging in various sectors.
• In the last five years, all the major energy-related institutions have completely reversed their forecast on coal consumption. From a 20-33% growth in world’s coal consumption till 2040, they now forecast stagnation and even reduction in consumption of coal. In India, the forecast on coal consumption has been revised downwards significantly.
• Energy efficiency improvements have helped restrain the growth in final energy demand in the world to just one-third of the level it would otherwise have been. The momentum towards energy efficiency is such that despite significant reduction in energy prices in 2016, investments in energy efficiency have increased. India has moved from incandescent bulbs to LEDs in 3 years.
• In 2016, for the first time, the electricity sector edged ahead of the oil and gas sector to become the largest recipient of energy investment. More than half of these investments went to the solar and wind sectors.
• Solar is now the cheapest source of energy during day-time in India. In the next 10 years, the price of solar is projected to reduce further by 50%.
• Smart grid, especially smart metering, is becoming mainstream. In 2016, about US $47 billion was spent on infrastructure and software to facilitate more flexible grid operation, demand management and integration of renewable resources. Large-scale smart meters are being installed at consumer and distribution transformer level in India.
• The price of Lithium-ion battery has declined by more than 50% since 2010. It is projected to decline further by 70-80% in the next 10 years.
• Induction cooking is now the most efficient, cleanest and the cheapest mode of cooking.
• From about 2 million currently, the number of electric vehicles on the road could reach 50-70 million by 2025. In fact, one in every three cars sold by 2030 could be electric.

Bilan prévisionnel de l’équilibre offre-demande d’électricité en France : synthèse. RTE, novembre 2017, 44 p. http://www.rte-france.com/fr/article/bilan-previsionnel

En vertu de ses missions légales, RTE a établi cinq scénarios pour la réussite de la transition énergétique, de l’hiver prochain à 2035.
Réalisé en concertation avec l’ensemble des acteurs (producteurs, fournisseurs, distributeurs d’électricité et de gaz, ONG, organisations professionnelles, universitaires et think-tanks, institutions) et élaboré à partir de 50 000 simulations, le Bilan prévisionnel établit des scénarios robustes et exhaustifs, conformément à la mission confiée par la loi à RTE…

Completion Design Changes and the Impact on US Shale Well Productivity / Trisha Curtis and Benjamin Montalbano. Oxford Institute for Energy Studies, Nov. 2017, 16 p. (Energy Insight: 21) https://www.oxfordenergy.org/publications/completion-design-changes-impact-us-shale-well-productivity/

The 2014 oil price downturn caused the US unconventional oil and gas industry to undertake an array of cost-cutting measures affecting both capital and operational expenditures. Focus shifted towards operational efficiency, well design, and the maximization of each dollar spent, and away from the gold rush mentality that had characterized the former $100/bl price environment. Perhaps counterintuitively, the emphasis on efficiency has helped to propel consecutive years of well productivity gains across several shale plays. These gains have continued into 2017, even as the industry still grasps at profitability. This Insight seeks to build on the 2016 paper Unravelling the US Shale Productivity Gains on well productivity gains. Specifically, it examines the continued productivity growth across multiple US shale plays and attempts to identify the factors contributing to this growth, as well as addressing some of the potential economic…

Southeast Asia Energy Outlook 2017 / IEA. Paris : OCDE, Oct. 2017, 146 p. http://www.iea.org/southeastasia/

The ten Association of Southeast Asian Nations (ASEAN) countries are among the most dynamic parts of the global energy system and a rising force in international energy affairs. Thanks to its growing partnership with Southeast Asia, the International Energy Agency (IEA) has conducted regular in-depth studies of the energy challenges facing this region. This new report, which was prepared as part of the IEA’s flagship World Energy Outlook series, provides insights for policy makers, industry and other energy stakeholders to help address the energy sector challenges facing Southeast Asia today.

The report highlights:

• The state of play across the Southeast Asia’s energy sector, based on the latest data and announcements.
• How today’s policies shape this region’s energy demand and supply outlook to 2040, and the implications for energy security, the environment and development.
• The opportunities that broader changes in global markets and low-carbon technologies open up for Southeast Asia.
• The investment required to improve efficiency and expand energy supply infrastructure, especially in the electricity sector.
• The mix of fuels and technologies that can help Southeast Asia achieve universal electricity access.
• An alternative pathway, the Sustainable Development Scenario, to meet energy security and environmental goals.
