风能和太阳能等多种可再生能源的发电量不断增加，导致人们要求增加储能能力。本文的核心目标是调查长期电力存储的市场前景，如水力泵存储、氢和甲烷从电力到天然气（PtG）转换技术。我们分析的主要结论是，就所有集中式长期存储技术而言，未来的前景远不如目前几篇论文和讨论中所指出的那样光明。尽管PtG技术具有很高的技术学习潜力，但它也将很难在电力市场上竞争。然而，氢和甲烷在交通运输领域仍有应用前景。与电力现货市场价格的停滞或下降相比，近年来运输业的燃料价格有所上涨。因此，此外，由于缺乏环保的移动燃料，可再生电力中的氢和甲烷可能成为一种经济的替代燃料，用于为乘用车提供燃料。 引文:2016年3月14日至16日在科威特召开的第六届国际能源研究与开发会议

Increasing Electricity generation from variable renewable energy sources like wind and solar has led to calls for additional storage capacities. The core objective of this paper is to investigate the market prospects of such long-term electricity storages as hydro pump storages, hydrogen and methane from power-to-gas (PtG) conversion technologies. The major conclusion of our analysis is that with respect to all centralized long-term storage technologies the future perspectives are much less promising than currently indicated in several papers and discussions. It will also become very hard for PtG-technologies to compete in the electricity markets despite a high technological learning potential. Yet, for hydrogen and methane there are prospects for use in the transport sector. Fuel prices in transport in recent years have rather increased compared to stagnation or decreases in electricity spot market prices. Consequently, and given in addition the lack of environmentally benign fuels for mobility hydrogen and methane from renewable electricity might become an economically alternative for fueling passenger cars.
