In a relatively short period of sixty-five years, aluminum has grown to the rank of fifth in total weight of met­als produced in the world. Throughout its short life, aluminum has been found to have excellent corrosion-resistant properties; yet only in recent years has aluminum been under consideration as a corrosion-resistant coating for iron and steel.

Three different oils: babassu, coconut and palm kernel have been transesterified with methanol. The fatty acid methyl esters (FAME) have been subjected to vacuum fractional distillation, and the low boiling point fractions have been blended with fossil kerosene at three different proportions: 5, 10 and 20% vol.

A new CEPS Task Force Report has identified possible pathways for achieving the EU’s ambitious climate change targets. It concludes that a GHG emissions reduction in line with EU climate change policy is possible, but it requires immediate action. This report argues that most of the reductions required of the transport sector in the EU could come from more energy-efficient vehicles, combined with the gradual introduction of low-carbon fuels and new engine technologies. The key policy for reducing GHG emissions in road transport is the steady tightening of emissions standards in line with technological progress. The report also identifies strategies for the transport system to become more energy and/or carbon efficient, arguing that leverage can be further enhanced by local and city governments’ incentives for efficient and low-carbon vehicles in line with local circumstances and choices. The Task Force on Low Carbon Transport brought together a diverse set of stakeholders from the car and oil industries, business associations, international organisations, member states, academic experts and NGOs. This authoritative report is the result of that unique collaboration.

This CEPS Task Force Report focuses on whether there is a need to adapt the EU’s electricity market design and if so, the options for doing so. In a first step, it analyses the current market trends by distinguishing between their causes and their consequences. Then, the current blueprint of EU power market design – the target model – is briefly introduced, followed by a discussion of the shortcomings of the current approach and the challenges in finding suitable solutions. The final chapter offers an inventory of solutions differentiating between recommendations shared among Task Force members and non-consensual options.

This Policy Brief describes the interaction between three approaches that are effective in driving innovation in low-carbon technologies. Based on that, the author provides four recommendations for making low-carbon technology support smarter. THE ISSUE Combating climate change on the global level will be much easier when abundant low-carbon technologies that are competitive in their cost and capabilities are available. But private companies underinvest in low-carbon innovation because they cannot capture the climate benefits. There are three policies to address this issue: pricing carbon, supporting deployment of as-yet uncompetitive technologies and supporting research and development.

Dynamic asset rating (DAR) is one of the number of techniques that could be used to facilitate low carbon electricity network operation. Previous work has looked at this technique from an asset perspective. This paper focuses, instead, from a network perspective by proposing a dynamic network rating (DNR) approach. The models available for use with DAR are discussed and compared using measured load and weather data from a trial network area within Milton Keynes in the central area of the U.K. This paper then uses the most appropriate model to investigate, through a network case study, the potential gains in dynamic rating compared to static rating for the different network assets - transformers, overhead lines, and cables. This will inform the network operator of the potential DNR gains on an 11-kV network with all assets present and highlight the limiting assets within each season.

Dynamic asset rating is one of a number of techniques that could be used to facilitate low carbon electricity network operation. This paper focusses on distribution level transformer dynamic rating under this context. The models available for use with dynamic asset rating are discussed and compared using measured load and weather conditions from a trial Network area within Milton Keynes. The paper then uses the most appropriate model to investigate, through simulation, the potential gains in dynamic rating compared to static rating under two transformer cooling methods to understand the potential gain to the Network Operator.

Brazil's Low Carbon Agriculture is one the initiatives that puts the climate in the agricultural agenda towards a more sustainable and adapted agriculture under global changes. Among the several practices listed and supported by the ABC Plan, zero tillage and integrated crop-livestock-forestry systems including the recovery of degraded pasture are the most relevant ones. The objective of this paper is to present the Geo-ABC Project, a procedure to monitor the implementation of the Brazil?s Low Carbon Agriculture (ABC Plan) and aiming at the development of remote sensing methods to monitor agricultural systems listed in the ABC Plan and adopted at local scale.
