Combined Heat and Power generation could be a smart solution to overcome the flexibility required to a modern power plant, this work investigates different layout possibilities allowing to increase the overall efficiency through the heat recover from the hot flue gasses after the heat recovery steam generator (HRSG) of a CCGT. The flue gas (FG) cooling aims to recover not only the sensible heat but also the latent heat by condensing the water content. One possible solution couples a heat pump to the flue gas condenser in order to increase the temperature at which the recovered heat is supplied, moreover the evaluated layout has to comply with the requirement of a minimum temperature before entering the stack.

It shows the main energy balance and the carbon footprint of a PtL plant for the production of 100,000 annual tonnes of methanol or 42,000 annual tonnes of gasoline in Norway. It discusses the ten year history of methanol and gasoline pricing and is giving the techno-economic discussion of the described plant in Norway.

Dies wird dadurch erreicht, dass in einer dritten Gaswascherstufe (III) eine zweite CO 2 -Wasche mittels einer Absorber- oder Einbautenkolonne (7) mit darin im Gegenstrom zur Waschflussigkeit gefuhrten Rauchgas- oder Abgasstrom durchgefuhrt wird.

Industry has developed several technologies for energy storage at MWh scale over short time-periods of hours. Energy storage, which takes advantage of resources from both the energy sector and industry, coupled with the production of fuels for transport, offers a unique chance to integrate more renewables in the electricity grid and enable sustainable, rapid decarbonisation of mobility. Fuels like methanol, gasoline, diesel or kerosene derived from hydrogen – produced from RES via water electrolysis – and CO2 – captured from industrial processes – have a lower CO2 footprint and do not compete with food production, unlike bioethanol or biodiesel. This technology offers a new business model to utilities, which today are restricted to heat and electricity produ...

Securing quality, competitiveness, and low environmental impact of final industrial products by changing conditions in the energy market requires extended efforts from the industry side. More specifically, the ongoing increase of RES' share in energy mix and the European targets on energy efficiency in industry have several implications, as well on technical aspects (additional requirements on flexibility, control reserve, dispatchable power generation, demand side management, energy storage), as also on economic aspects (decrease of whole sale electricity price, increase of taxes and surcharges, disruptive business models). In this changing landscape the task of matching energy supply with energy use following a continuous optimization process becomes of prime importance. Mitsubishi Heavy Industries has developed ENERGY CLOUD Service, an integrated toolbox of solution...

In this framework future trends in power plant design are presented towards: further increase of efficiency through thermal cycle optimization and fuel predrying retrofit options for faster load change and extension of load range integration of electricity storage concepts in power plants product diversification and cross-sectorial energy storage and utilization (Power to Heat, Power to Chemicals) as well as for maximizing the plant utilization. It is shown that these technologies can significantly improve the economics of power plant operation and also have much lower carbon footprints, when renewable energy is integrated in the operation.

European Union (EU) energy strategy includes the EU low-carbon roadmap milestone, which indicates for 2020, a 20% reduction in carbon emissions, and a 20% EU-wide share for renewables, and by 2030 a 40% reduction in carbon emissions and 30% EU-wide share for renewables. The increased renewable energy sources (RES) penetration and their intermittent energy production have led to the emerging need for energy storage technologies. Especially in the European energy market, large-scale energy balancing with sustainable technologies with product flexibility and cost-effective operation are being investigated. The carbon capture and utilization (CCU) concept, as a means for low-carbon sustainable industries, is integrated in the energy storage technologies. The present paper addresses the integration of power to fuel concept in the energy storage sector with simultaneous emission reduction. Grid m...
