Climate change and CCS increase the water vulnerability of China's thermoelectric power fleet

Large numbers of China's thermal power plants are in water-stressed regions. Changes in the availability of water resources due to climate change may impact the vulnerability of regional and national electricity generation. Here we explore this vulnerability for coal-fired power units (CPUs) as the generation-type most exposed to climate risk....

Biodiversity Loss from Freshwater Use for China’s Electricity Generation

A Quantum Approach for Tactical Capacity Management of Distributed Electricity Generation

Matching electricity demand and supply by decentralised generators will be very important in the near future, where more and more electricity has to be produced sustainably. Optimisation problems that address this problem often have quadratic objective functions or constraints, due to the quadratic nature of energy loss. Where classical solvers...

Future European shale gas life-cycle GHG emissions for electric power generation in comparison to other fossil fuels

The carbon footprint of shale gas combusted in Europe was estimated from nine European shale gas plays as potential production regions. Greenhouse gas emission sources during shale gas production, such as fugitives from hydraulic fracturing or combustion emissions from horizontal drilling, were added to emissions occurring for conventional gas...

Job creation and economic impact of renewable energy in the Netherlands

This study evaluates the economic impact of a shift towards renewable electricity mix in the Netherlands using the neo-Keynesian CGEM ThreeME (Multi-sector Macroeconomic Model for the Evaluation of Environmental and Energy policy). This scenario has been inspired by the Urgenda's report ‘Energy 100% Sustainable in the Netherlands by 2030’, which...

Simultaneous production of high-quality water and electrical power from aqueous feedstock’s and waste heat by high-pressure membrane distillation

A new membrane distillation (MD) concept (MemPower) has been developed for the simultaneous production of high-quality water from various aqueous feedstocks with cogeneration of mechanical power (electricity). Driven by low-grade heat (waste, solar, geothermal, etc.) a pressurized distillate can be produced by operating TNO’s Memstill® process...

A hot plate solar cooker with electricity generation-Combining a parabolic trough mirror with a sidney tube and heat pipe

Solar cookers supply clean and sustainable energy for cooking and so limit the use of wood or charcoal. A new type of solar cooker is developed with a hot plate. The hot plate offers comfortable access to the food under preparation. The hot plate opens up the opportunity to generate small amounts of electricity with the help of a thermo electric...

The role of CO2-enhanced coalbed methane production in the global CCS strategy

Subsurface coal seams are generally considered as important potential geological media for underground storage of carbon dioxide, but this is a more complex option than other storage options. The required number of wells and the uncertainties due to the complexity were generally considered as main barriers and large-scale projects are hence...

Optimized power generation in offshore wind parks

Electricity generation on offshore wind parks has an increasing economic importance - the European Commission foresees that 12% of the wind energy will be produced on offshore installations by 2020, and this share is likely to increase further in the following years. However, the continuously varying offshore environment and the interaction...

New process concepts for CO2 post-combustion capture process integrated with co-production of hydrogen

This work describes a study in advanced post-combustion based on CO2-capture technologies to be integrated within the Hypogyny concept (electricity generation with co-hydrogen production). Two different Hypogen concepts based on integrating IGCC (Integrated Gasification Combined Cycle) and post-combusting CO2 capture are proposed and...

Wetting a rail tanker behind a noise shield

In the Netherlands, the Betuweline is a dedicated freight railway. It will, among other things, be used for transportation of all kinds of hazardous materials from the Port of Rotterdam to the German Hinterland and vice versa. The line is approximately 150km long. Alongside the line, over more than 100 km noise shields are apparent. The question...

A basic analysis of cogeneration economics

The economics of small scale gas turbine based cogeneration systems are analyzed on the basis of avoided costs for an electric utility exploiting such systems. This concerns a theoretical study in which the cogeneration system as a means for electricity generation is assumed to supplant the building of new central electricity generating plant....
