The mixing of freshwater and seawater where rivers flows into the salty ocean releases large amounts of energy. This energy can be harvested and made into electricity using pressure retarded osmosis (PRO). This is the concept of osmotic power, a new and yet unexploited source of renewable energy. The idea of exploiting the energy from mixing fresh water and sea water with PRO was first developed by Prof. Sidney Loeb in the early seventies. After some years in the eighties with limited progress in the field, the Norwegian power company Statkraft engaged in technology develop- ment in the mid nineties aiming at cost-effective osmotic power production. Today Statkraft is the world leader in development of osmotic power, and have made state of the art achievements during the last few years. The work has been focused on the design and production of a semi-permeable membrane optimized for osmotic power. During these years the power density of the membrane has increased from less than 0,1 W/m2 up to today's membranes producing close to 3 W/m2. The target of 5 W/m2 necessary to produce osmotic power on commercial basis seems within a few years time. The development has consisted of testing existing membranes, and improving these, as well as designing completely new membranes. An insight to this work will be given, and also give some results from the testing of existing and novel membranes operated in PRO. The world's first osmosis driven power plant will be put into operation during 2009 in the southeast of Norway. The main objectives of the prototype are twofold. Firstly, confirming that the designed system can produce power on a reliable 24-h/d production. Secondly the plant will be used for further testing of technology achieved from parallel research activities to substantially increase the efficiency. These activities will mainly be focused on membrane modules, pretreatment of water, pressure exchanger equipment and power generation (turbine and generator). The presentation will give a brief introduction to the prototype system, the expectations for operation and maintenance, and also some outline of the next steps in the development of osmotic power. The paper gives a general overview of the obstacles that needs to be addressed, and expectations of the results that should be achieved. With these assumptions handled, osmotic power can develop into a new, renewable source of energy well capable of competing on the energy market in the near future. Once again, Prof. Sidney Loeb contributes to solve one of the major challenges to establish a sustainable world for the next generations. © 2010 Desalination Publications. Source

The procedure of fitting rating curves in channels where the stage-discharge relationship is subject to changes driven by morphological processes remains one of the major unsolved problems in hydrometry. This paper addresses this issue by formulating the stage-discharge relationship as a steady flow, one-segmented power law model with parameters that are viewed as stochastic processes with characteristics associated with the temporal instabilities of the channel elements governing the stage-discharge relationship. A Bayesian analysis with informative priors and time-stage-discharge measurements as forcing data is used to determine the most plausible model and its posterior parameter distributions using Markov chain Monte Carlo simulation techniques and particle filtering. The proposed framework is applied to data from gauging stations in two unstable rivers and one stable river in Norway. Copyright 2011 by the American Geophysical Union. Source

I examine sustainability and benefit-sharing mechanisms in the context of the Theun-Hinboun Expansion Project (THXP) in central Laos. THXP has been planned and implemented in accordance with international good practice, and is now at the stage of preparing for closure on a number of key issues, in particular on livelihood restoration. With most of the infrastructure and service improvements completed, the long-term challenge relates to institutional development, environmental management and sustainability of the new livelihood systems. A strategy is being developed to ensure that local government, the private sector and the Theun-Hinboun Power Company (THPC) contribute in terms of budget, staff and expertise to ensure sustainability is achieved by 2017, or until targets are met and local communities can manage resources on their own. This approach to mitigating project impacts is an example of a new paradigm in which hydropower can achieve sustainable development for project affected communities. © 2014 Elsevier B.V. Source


Munich-based Tado, maker of smart thermostat and AC control products, has raised another $23 million for further international expansion. The new investment is led by Inven Capital, the venture capital arm of the Čez Group, a multinational energy conglomerate based in the Czech Republic. It’s the startup’s third funding round and brings the total raised to $57 million since being founded in 2011. Tado’s previous backers include the venture capital unit of Siemens AG, and Statkraft Venture Capital, the investment company of Europe’s largest producer of renewable energy. In addition, Target Partners, Shortcut Ventures and BayBG are also investors. Sharp-eyed readers will have noticed that, along with a number of traditional VCs, Tado’s investor list has a definite strategic bent to it, spanning the energy industry, including renewables, along with one of Germany’s largest engineering companies. That plays into the fact that the startup’s longer term mission is to not only make home climate control smarter for the benefit of each individual household but also the environment and national energy grid as whole. The company’s two current products are a smart thermostat — resulting in Tado sometimes being called the Nest of Europe — and a smart AC controller. Both enable a home’s heating/cooling to be controlled via the Tado smartphone app, with a flagship geo-location feature that means Tado is able to know when you have left home or are returning and adjusts your heating or air conditioning accordingly. This, co-founder and CEO Christian Deilmann argues, is better than a purely ‘self-learning’ approach, such as that utilised by Nest, or relying on schedules alone, however much easier they are to program using a modern smartphone app. In a call yesterday, he said that Tado’s location-based automation is still the main feature that provides differentiation from competitors at the point of sale in retail stores, such as Dixons Group in the U.K., where the Tado will often be sitting alongside products from Google-owned Nest or British Gas’ Hive. He also says 87 per cent of all Tado users take advantage of the geo-fencing functionality to automatically control their home’s climate. But actually Tado is a much deeper tech play than smartphone and location-based control of your home’s heating and cooling systems alone. The startup’s smart thermostat has been painstakingly engineered to be able to connect to a boiler’s digital serial interface, more typically found in heating systems in Germany and elsewhere in Europe and in newer systems in general, which enables the cloud service to be able to do all sorts of other clever things. This includes the ability to modulate heating, rather than simple switching the boiler on or off, as well as monitor the health of a house’s heating system remotely, sending diagnostics to a maintenance company or engineer. The former offers much greater energy efficiency, says Deilmann, while the latter can help prevent a boiler from failing outright because problems can be more easily caught in time. Tado currently offers its diagnostics portal to partner installers and services companies as a way to build long term value into those relationships. However, in future it could monetize that aspect of its offering via, for example, a marketplace for parts or by providing a library of technical information in the cloud. Then there’s the way Tado is planning to make its service smarter for the benefit of energy management overall, including at the national grid level. In practice this means partnerships with local utilities companies — and is perhaps where the startup’s strategic investors come even more into focus — to enable Tado and its customers to opt into ‘demand response’ schemes so that a home’s heating and cooling systems are utilised where possible outside of known peak energy times. This could be a simple as turning your heating down by a few points without it really being noticeable or heating your home up a little ahead of time. In aggregate, this can make a tangible difference to the national grid’s ability to stabilize energy consumption and production, and, says Deilmann, is where the bigger picture of smart home climate control really kicks in.
