Energyplexes for the 21st century: Coal gasification for co-producing hydrogen, electricity and liquid fuels

Abstract

This paper illustrates the role that integrated energy systems, also known as ‘energyplexes’, could play in supplying energy demands in the long term. These systems could enable a multi-fuel, multi-product strategy with both economic and environmental benefits. They could increase the adaptability and robustness of energy-services companies in the marketplace, providing them with flexibility in meeting demands in different market segments while achieving lower production costs and, reducing the risks of reliance on a single feedstock. In addition, with the possibility of achieving high conversion efficiencies and low polluting emissions and facilitating carbon capture, they could deliver high-quality energy services in a cost-effective way while meeting stringent
environmental requirements. Their potential is highlighted here using the case of coal-fired, synthesis-gas-based gasification systems that allow co-producing hydrogen, electricity and liquid fuels, i.e. Fischer–Tropsch liquids and methanol, and could be a key building block in a clean-coal technology strategy. Co-production, also known as poly-generation, strategies may contribute to improve the economics of the system and exploit potential synergies between the constituent processes. However, the technical feasibility and economic viability of poly-generation schemes have to be examined carefully on a case-by-case basis.

  1. I rarely leave a response, however i did some searching and wound up here Energyplexes for the 21st century:
    Coal gasification for co-producing hydrogen, electricity and
    liquid fuels | Energy Conservasion. And I do have
    some questions for you if you usually do not mind. Is it only me or does it seem
    like some of these responses come across like they are written by brain dead
    visitors? 😛 And, if you are writing at other social
    sites, I’d like to keep up with everything fresh you have to post. Would you make a list of every one of all your communal pages like your twitter feed, Facebook page or linkedin profile?

  2. What’s up to every one, as I am genuinely eager of reading this webpage’s post to be updated daily.
    It consists of fastidious material.

  3. “Energyplexes for the 21st century: Coal gasification for co-producing hydrogen, electricity and liquid fuels
    | Energy Conservasion” was a fantastic article.
    If it included even more pix it would probably be
    perhaps even even better. Thank u -Jamal

  4. If you desire to increase your know-how simply keep visiting this web site
    and be updated with the latest news posted here.

  5. “Energyplexes for the 21st century: Coal gasification for co-producing hydrogen, electricity and
    liquid fuels | Energy Conservasion” seriously got me personally addicted with ur web site!
    I actuallywill probably be back again far more often.
    Thanks a lot ,Alphonse
