Long-term storage (annual or seasonal storage) of solar-collected thermal energy in native rock or sandstone appears to be both technically feasible and economically attractive. In this storage concept, a large bed of crushed or naturally formed porous rock is heated by hot air flowing from a ...
Long-term storage of spent nuclear fuel and high-level radioactive waste Storage of radioactive materials must be done in a safe and secure manner. The varied physical characteristics of these materials, coupled with unique chemical and radioactive attributes, require isolation and containment to ...
At the Fraunhofer Institute for Solar Energy Systems in Freiburg, Dr. Gunter Ebert says hydrogen and methane are the only options for large-scale “season storage.” A battery can provide some short-term storage capacity, maybe up to 50 gigawatt-hours, as can pumped hydro, but “we need a...
Reliability of electric power supply for all types of industrial, commercial, and institutional customers using computer and electronic loads requires energy-storage means and inverters to transition intervals of electric utility interruption. Requirements for energy storage are divided into short-term for ...
Long- term latent energy storage in Canada has involved the seasonal storage of winter's cold for use in cooling buildings. Some Canadian continental climates characterized by a long, cold winter with a brief hot summer are ideal for the seasonal storage of cold to offset summer cooling peaks....
Batteries are rapidly becoming less expensive and might soon offer a cheap, short-term solution to store energy for daily energy needs. However, the long-term storage capabilities of batteries, for example, in a yearly cycle, will not be economically viable. Although pumped-hydro storage (PHS)...

The invention relates to a long-term heat storage device for long-term storage of solar energy and other types of energy, in the heat storage material of which a rock bulk material (1), in particular of volcanic origin, such as diabase, ... V Petrovic - WO 被引量: 3发表: 0年 A ...
Thermal energy storage offers enormous potential for a wide range of energy technologies. Phase-change materials offer state-of-the-art thermal storage due to high latent heat. However, spontaneous heat loss from thermally charged phase-change materials
