Helios Thermal Energy Storage System

能源储存以满足日益增长的需求对于发展低碳能源系统至关重要，可以为电网提供更多的灵活性和平衡性，并提供应对间歇性可再生能源使用增加的手段。在当地，它有可能大幅降低企业和家庭的能源成本。目前的商业规模的存储解决方案在其开发和存储成本方面还为时过早，因此商业市场的吸收非常有限。为了具有成本竞争力，每千瓦时成本必须低于非高峰电价（0.07英镑/千瓦时）。太阳神有限公司，一个微型中小企业，正在寻求测试开发一个综合的热和电力储能系统（TESS）的可行性。该设备将启用besmart-enabled，并将利用非高峰电力在高密度介质中以约0.02英镑/千瓦时的速度存储热能。该设备将使用斯特林电机在高峰时段发电，热损失将用于加热水矩阵用于加热或热水。如果需要，该设备还将能够将能量反馈到电网中，并存储来自太阳能光伏等可再生能源的能量。

Energy storage to meet increasing demand is vital to developing a low-carbon energy system, and can providemore flexibility and balancing to the grid, as well as providing a means of coping with increasing use ofintermittent renewable energy. Locally, it has the potential to drastically reduce energy costs for businessesand homes. Current commercial-scale storage solutions are too early in their development & storage costsoutweigh energy savings so commercial mkt uptake has been very limited. To be cost competitive, cost perkWh must be lower than off-peak electricity prices (£0.07/kWh). Helios Limited, a micro SME, are seeking totest the feasibility of developing a combined heat & power energy storage system (TESS). The device will besmart-enabled, and will utilise off-peak electricity to store heat energy at ~£0.02/kWh in a high densitymedium. The device will use a Sterling motor to generate electricity at peak hours, and heat losses will be usedto heat a water matrix for heating or hot water. The device will also have the ability to feed energy back intothe grid if needed, and store energy from renewable energy sources such as solar PV.
