The past term has witnessed impressive worldwide dynamic growth of CSP plants led by Spain and the US, and rapid parallel growth in SolarPACES membership, from 12 to 20 member countries. This increased strength helped reinforce our worldwide dissemination activities, most visibly in this year’s 17th SolarPACES Symposium, which is expected to have an attendance of nearly 1000. We are very pleased to see how this traditional event has grown in response to the increasing need for an independent platform where experts from R&D, industry, policy and financing can meet. Maintaining and increasing the impact and quality of the SolarPACES Symposium will be one of the high priority tasks in the upcoming five-year term starting in 2012. Global power supply has risen significantly in the political agenda of many countries as a consequence of the tragic Fukushima accident last March. Renewable Energies in general had already achieved a significant share in the overall energy mix in many countries, and this trend seems to have received stronger political support since then. As the shares of fluctuating renewable sources increase, the ability of each technology to match demand is of growing importance, and concentrating solar technologies, with their specific potential to provide short- term (thermal/power) and long-term chemical storage, have a lot to contribute to the optimal integration of the largest renewable source of clean, sustainable and affordable energy still to be tapped, the sun. Against this background in the coming term, an even stronger SolarPACES will focus on the internationally coordinated development and deployment of concentrating solar technologies to further reduce cost, increase dispatchability, and reinforce awareness of the benefits of CST. While we are still heading in the same direction, personal changes are sometimes unavoidable. We want to express our most heartfelt gratitude to our former Chairman, Dr. Thomas Mancini of Sandia National Laboratories, who resigned as Chairman in April 2011, after serving SolarPACES for seven years in this capacity (and many more years as Operating Agent). We are all indebted to Tom Mancini’s dedicated effort to the progress and development of the SolarPACES Implementing Agreement. The growing SolarPACES community will stay in close touch and wishes him a sunny retirement. As we are now looking forward to the election of a new Chairman in the autumn ExCo Meeting, we would also like to express our gratitude to the continuing Operating Agents and ExCo Members of SolarPACES for their dedication to our common goals, and hope to keep on working with this great team in the future. , Robert Pitz-Paal Christoph Richter Acting Chair Executive Secretary iv ANNUAL REPORT 2010 SOLARPACES SOLARPACES TABLE OF CONTENTS v Table of Contents Page FOREWORD R.

The Annex I Expert Group oversees development of analytical papers for the purpose of providing useful and timely input to the climate change negotiations. These papers may also be useful to national policy makers and other decision- makers. In a collaborative effort, authors work with the Annex I Expert Group to develop these papers. However, the papers do not necessarily represent the views of the OECD or the IEA, nor are they intended to prejudge the views of countries participating in the Annex I Expert Group.

The paper does not constitute advice on any specific issue or situation.

Comments are welcome, directed to [email protected]. INTERNATIONAL ENERGY AGENCY The International Energy Agency (IEA), an autonomous agency, was established in November 1974. Its primary mandate was – and is – two-fold: to promote energy security amongst its member countries through collective response to physical disruptions in oil supply, and provide authoritative research and analysis on ways to ensure reliable, affordable and clean energy for its 29 member countries and beyond. The IEA carries out a comprehensive programme of energy co-operation among its member countries, each of which is obliged to hold oil stocks equivalent to 90 days of its net imports. The Agency’s aims include the following objectives: n Secure member countries’ access to reliable and ample supplies of all forms of energy; in particular, through maintaining effective emergency response capabilities in case of oil supply disruptions. n Promote sustainable energy policies that spur economic growth and environmental protection in a global context – particularly in terms of reducing greenhouse-gas emissions that contribute to climate change. n Improve transparency of international markets through collection and analysis of energy data.

It has been accepted for inclusion in Land & Water Law Review by an authorized editor of Law Archive of Wyoming Scholarship. Tiedeken: Access Rights for the Solar User: In Search of the Best Statutory COMMENTS ACCESS RIGHTS FOR THE SOLAR USER: IN SEARCH OF THE BEST STATUTORY APPROACH "In the final analysis, almost all the energy avail- able to man is solar: fossil fuels are simply the stored legacy of past photosynthesis, the fissionable elements are formed in a solar furnace; and a ther- monuclear,1 fusion reaction is essentially a miniature sun." The above statement contains a profound fact that was long overlooked in our energy consumptive society. Not until the oil embargo of 1973 did the United States begin to consider solar energy as a viable, efficient replacement for the energy needs of the country. Clearly the substitu- tion of solar for fossil fuels or nuclear energy would re- quire enormous capital expenditure, however, solar power is extremely attractive as a source of energy at the local level.2 Moreover, with the onslaught of the need to develop new energy sources it was soon discovered that the legal system did not encourage the wide-scale development of solar power.

High thermodynamic efficiencies achieved by collecting and storing heat at Thermal energy storage (TES) higher temperatures, and recent maturing of the technology, are making molten-salt central receiver plants the Molten salt preferred option for CSP. To explore potential further improvements in CSP efficiency and cost the world’s first Direct absorption receiver (DAR) direct absorption molten salt volumetric receiver/storage system was built at pilot scale, commissioned and Volumetric solar receiver Beam down tower monitored. In this demonstration a 100 kWth beam-down tower directs solar radiation through a final concen­ Secondary concentrator trator into the open aperture of a 1.94 m high and 1.25 m internal diameter tank receiver situated near the ground.
