This work assesses the feasibility of using energy storage to make a step-change improvement in control for off-grid and on-grid wave energy arrays. This has been brought about by a need for arrays of smaller wave energy devices to utilise the less-energetic wave resource off the coast of China. For a lower energy resource, control of arrays is even more important in order to optimise performance and to improve survivability. As the focus is on future deployment of arrays in China, the step-change is only possible with the expertise in wave climate, off-grid connection of devices and power systems in China; hence this contribution is provided by project partners in China.

This collaborative UK-China project proposes will establish a suite of Decision Support Tools (DSTs) that incorporate knowledge advances from the ongoing Phase 1 UK-China Critical Zone science research programme. With these advances, DSTs currently used in the UK and China will be adapted, expanded, tested and applied. The DSTs, data sets and decision outcomes will guide and evaluate site-specific innovation in soil and water management, and create roadmaps to scale up impact outcomes and plans to regional and national scale in China. The project will integrate the teams and research results of the 5 projects funded in Phase 1. Phase 2 will deliver immediate innovation in decision support methods and their application, and pathways to long-term impact and ODA outcomes: to restore ecosystems, improve soil fertility and water quality, improve farming livelihoods and improve food and water security. Impact delivery will focus on 5 critical zone observatories (CZOs) in China, established in Phase 1, which are located in regions with large-scale environmental and economic challenges related to degraded soil and water resources. 1. Hydro Karst CZO in SW China - land use and water quality linked to nutrient contamination of aquifers and surface waters in transmissive carbonate terrain 2. Peri-Urban CZO in the Yangtze delta - soil contamination from urban atmospheric deposition and intensification of agricultural chemical use 3. SPECTRA Karst CZO in SW China - Ecosystem degradation and karstic desertification linked with soil erosion and loss of soil fertility 4. Red Soils CZO - loss of soil fertility from intensification of agricultural production 5. Loess CZO - ecosystem degradation under intensification of rural land use Participatory research with stakeholders in China will identify the land, water and food demand conflicts that need be addressed in the regions of the CZOs. This KE is designed to avoid a recognised mismatch between the way DSTs are conceptualised by scientists and how DSTs may be most effectively used by stakeholders. Recent reviews of DSTs for land, water and food sustainability provide a platform for assessing the suitability of different DSTs to the challenges of China. The UK and China teams and stakeholders will identify the most promising DST approaches and test these using the data sets of the 5 CZOs. The outputs will be tested with a wider set of DST users and potential users. The outcomes will allow mapping DSTs and their suitability to address soil and water management challenges at the 5 CZO sites. This work will assess effectiveness of the DSTs across the scales of interest for stakeholder groups at the sites. This will include identifying sustainable practices, the scale at which the CZO and related measurements strengthen the evidence base and inform practices for management decisions, and how adaptations in a DST methodology would improve site-specific application. The project will apply national data sets on the geographic variability of soil and water resource demand and use patterns, and natural conditions of geology, soil, vegetation cover, climate and weather. Through engagement with regional planners, the project will design pathways to scale up the DST outcomes for application in regional-scale resource planning. The final stage will be synthesis of the adapted, applied and upscaled DST methods into practical guidance in how to deploy the DSTs in regionally specific contexts, the capabilities of different DSTs and applicability of DST outputs. The institutional partners in China will publish the guidance and organisations will be identified and trained as superusers to disseminate training. Superusers will conduct a series of regional workshops in China, led by Chinese partners, to create a network of users who are at the forefront of innovation in soil and water management planning and implementation.

The Earth's surface (soil and plants), and the rock underneath interact, linked by rainwater flowing through the soil into the rock. The soil imparts a chemical signature to the water, sometimes bad leading to loss of water quality. This signature is mediated by movement through the rock, and then, when underground water re-emerges, in streams and rivers by bacterial activity. As such, how this outer layer of planet Earth functions is 'critical' to key needs of mankind - how much water we have available and its quality; how well the soil functions as a result of water draining through it. The study of how these layers interact is thus called 'critical zone' research. Our research programme uses such 'critical zone' research in an environment where the local residents face significant environmental challenges - in rural China, an area of rapid growth and where many live under the poverty line. This is a joint research programme between UK and China. We will focus on two of these challenges: water availability and quality, and how movement of water in the critical zone influences surface vegetation. Crucial to this research is that the underlying rock is mostly limestone. Limestone is easily dissolved and water can move very quickly through the subsurface. So soils may dry sooner (as the subsurface beneath is freely-draining) and there is limited water storage on the surface and underground. Limestone is widely distributed world-wide, but particularly in China and so study here is relevant to many world-wide. The people living in the catchment generally live-off-the-land. It provides their water and food - a phenomenon known as the ecosystem providing services. Where the slopes are not too steep, the land surface is heavily-cultivated. This in turn presents problems e.g., the water quality is poor, with dangerously high-level of nitrate (a chemical that is found in fertiliser); clearance of vegetation exposes rock, limiting how land may be used. Further challenging to local residents is that the climate is changing. How rain is delivered to the catchment has been changing such that water is not available as before. Thus there have also been water shortages, and this led to crop failure and so loss of food. Land use change is important in shaping these ecosystem services, but climate change may be one of the most significant threats the residents will face; science must help them prepare for facing these threats with successful outcomes. Our research will generate models of how the critical zone functions currently and from these we can then investigate how the critical zone functioning may adapt to different environmental drivers. There is a large body of scientific modelling outside this project that has identified how the climate may change. Thus, we can draw on this to run the models we will develop of the critical zone functioning, not only under land use change, but also under future climate scenarios. All this research will contribute to understanding where this catchment critical zone is most sensitive to future threats. However, it is important that this understanding reaches the people who need to use it. So the final activity we will undertake comes under the umbrella of 'knowledge exchange' - sharing our findings with those who need this research, and adjusting our understanding based on knowledge they too have. Thus our last, but not least, activity is working with those who live in the landscape and those who manage it, to help them identify how their activities can cause the least harm and offer the most protection to their ecosystem services. Our collaboration with Chinese colleagues is therefore crucial. We bring new skills to the project (e.g. new hydrological modelling skills) that they will benefit from. Additionally as catchment management practices will be quite different across UK-China, they will learn about other good practice to help improve their environment and remove residents from poverty

The consortium submitting this proposal stems from the UK-China Network on Clean Energy Research that was setup by Prof. Haifeng Wang in January 2007 with 202k of financial support from EPSRC under its INTERACT 4 scheme. The goal of the Network is to disseminate and promote in China the research that the EPSRC SUPERGEN consortia have carried out in the UK. The proposed consortium thus extends the scope of the Network to the organisation of joint research between the UK SUPERGEN researchers and leading Chinese scientists of nationally funded research programmes. It is thus built on the basis of an existing link between members of the Network, Chinese universities and the Chinese Academy of Sciences. It also expands this collaboration to the two largest research institutes in power engineering in China: the China Electric Power Research Institute (EPRI) and the Nanjing Automatic Research Institute (NARI). All of the 9 UK investigators play a leading role in one or more of six SUPERGEN consortia that are sponsored by EPSRC to carry out focused collaborative programmes of research on various aspects of sustainable energy systems.Even though the power systems of the UK and China are at different stages of development, the issue of how to maintain security while accommodating an increasing amount of renewable generation capacity is an important concern in both countries. To achieve sustainable economic growth, these power systems will need to become more flexible and more robust. Engineers and scientists in the UK and China have complementary expertises in this area. Researchers in the UK have done a significant amount of work in recent years on renewable energy sources and their integration with the grid. On the other hand, security analysis and security enhancements techniques have been central R&D issues in China. Combining these expertises and facilitating a two-way transfer of knowledge would therefore clearly accelerate the pace of research on problems of common interest. We therefore propose to bring together the leading power system scientists from the UK SUPERGEN consortia and from the Chinese nationally funded projects to form a collaborative research team to study the sustainable security of power systems. Being able to assess and enhance the security of power systems is a key issue in the development of sustainable power systems. It is also a long-standing and complicated scientific and engineering problem with considerable breadth and depth. This proposal integrates 8 joint research projects that tackle the problem from the four most important perspectives, i.e., security analysis (JP1 and 2), renewable generation (JP7 and 8), protection (JP3 and 4) and control (JP4, 5 and 6). Two core projects, JP1 and 2, will develop new models and analytical methods for gaining a better understanding of power system sustainable security. They require input and support from JP7 and 8 on renewable generation and provide guidelines and tools to JP3, 4, 5 and 6 to enhance the sustainable security through power system protection and control. The contribution of the Chinese collaborators will be very significant as they have a strong experience with engineering practice and they have access to advanced experimental facilities that are not available in the UK. They have committed 4 post-doctoral researchers and 13 PhD students to work on the joint projects . These researchers are fully funded from sources in China. The Chinese collaborators have also pledged to seek further financial support in China to contribute to the Consortium if this application is successful. The proposed consortium has designed 3 schemes to ensure a two-way UK-China knowledge transfer through this collaboration. They are major dissemination events, UK-China training exchange and project meetings. The project will start on the 1st Oct. 2008 and run for 4 years.
