Low-carbon hybrid energy systems -- China's future energy solutions

11.02.2013
A low-carbon solution to high-carbon energy resources such as coal is proposed by their high efficient integration with either nuclear or renewable energy, which may figure out the strategic solution to China's future energy development. As a result, the research on "low-carbon hybrid energy system-- strategic solution and development patterns for China's future energy" has been published on SCIENTIC SINICA Chimica iin Chinesej, No.1, 2013.

Coal dominated energy resource and consumption structure in China. This leads to the great challenges for China's future energy development along with both growing demand for energy and high pressure for CO2 emission reduction. From the earlier viewpoint, the reduction of CO2 emission could be reached by replacing fossil fuel by low-carbon energy resources for electricity generation. However, it gave rise to the questions.


This shows the carbon flow for the hybrid energy system.

Is it possible to directly using low-carbon energy on the reduction of CO2 emission? Is there an efficient way to decrease the emission of CO2 by low-carbon energy, and utilize the C and O in CO2 to produce useful materials? Thus, a potential scheme is proposed to couple coal with the low-carbon energy via the high efficient integration, including nuclear, wind, solar, biomass and hydro power etc. Such a hybrid energy system may target both CO2 reduction and recycle on a large-scale.

The carbon flow for hybrid energy system is based on the utilization of carbon resources and the process of carbon recycling. High-carbon energy resources such as coal could be coupled with low-carbon energy resources such as nuclear energy and renewable energies by the effective integration between substances, energy and information. In principle, hear or electricity is generated by the low-carbon energy such as nuclear and renewable energy, then input to drive the high/low temperature electrolysis reaction and to provide H2 for high-carbon system. In this case, the water-gas shift reaction is replaced to suppress the CO2 emission. On the other hand, CO2 utilization could be carried out through CO2 hydrogenation. Consequently, both energy and carbon efficiency could be highly improved with a reduction of CO2 emission, and at the same time CO2 could be used as a resource.

Based on the above consideration, nuclear-assisted coal-based energy system and wind/solar-assisted coal (biomass)-based systems are analyzed as the case study for the preliminary techno-economic evaluations with detailed explanations provided. Such an integration is revealed to produce energy and chemicals with a simultaneous increase in both energy and carbon efficiency of fossil fuel. Hence, the low-carbon hybrid energy system can be considered as the potential solution to China's future energy development.

Obviously, the low-carbon hybrid energy system has the advantages of both high-carbon resources (such as coal) and low-carbon energy resources (such as nuclear or renewable energy) for the production of liquid fuel and chemicals on a large scale. It focuses on the current energy situation in China, fits the direction of energy development in China, and provides the strategic solution to China's future energy.

The research is supported by the "Strategic Priority Research Program" of the Chinese Academy of Sciences (Grant No.XDA02000000) and the project of "Techno-economic evaluation of integrated energy system" from Shell Global Solutions International B.V.

Im Focus: OU astrophysicist and collaborators find supermassive black holes in quasar nearest Earth

A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.

The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...

Im Focus: What would a tsunami in the Mediterranean look like?

A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).

Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...

Im Focus: Self-healing landscape: landslides after earthquake

In mountainous regions earthquakes often cause strong landslides, which can be exacerbated by heavy rain. However, after an initial increase, the frequency of these mass wasting events, often enormous and dangerous, declines, in fact independently of meteorological events and aftershocks.

These new findings are presented by a German-Franco-Japanese team of geoscientists in the current issue of the journal Geology, under the lead of the GFZ...

Im Focus: FIC Proteins Send Bacteria Into Hibernation

Bacteria do not cease to amaze us with their survival strategies. A research team from the University of Basel's Biozentrum has now discovered how bacteria enter a sleep mode using a so-called FIC toxin. In the current issue of “Cell Reports”, the scientists describe the mechanism of action and also explain why their discovery provides new insights into the evolution of pathogens.

For many poisons there are antidotes which neutralize their toxic effect. Toxin-antitoxin systems in bacteria work in a similar manner: As long as a cell...

Im Focus: Fraunhofer IPA develops prototype of intelligent care cart

It comes when called, bringing care utensils with it and recording how they are used: Fraunhofer IPA is developing an intelligent care cart that provides care staff with physical and informational support in their day-to-day work. The scientists at Fraunhofer IPA have now completed a first prototype. In doing so, they are continuing in their efforts to improve working conditions in the care sector and are developing solutions designed to address the challenges of demographic change.

Technical assistance systems can improve the difficult working conditions in residential nursing homes and hospitals by helping the staff in their work and...
