Helios Thermal Energy Storage System

储能以满足日益增长的需求对于开发低碳能源系统至关重要，它可以为电网提供更大的灵活性和平衡性，并提供一种应对日益增长的间歇性可再生能源使用的手段。在当地，它有可能大幅降低企业和家庭的能源成本。目前商业规模的存储解决方案开发还为时过早，存储成本超过了能源节约，因此商业Mkt的应用一直非常有限。为了具有成本竞争力，每千瓦时的成本必须低于非高峰电价(GB 0.07/千瓦时)。微型中小企业Helios Limited正在测试开发热电联产储能系统(TESS)的可行性。该设备将支持定制，并将利用非高峰电力在高密度介质中以0.02 GB/kWh的速度储存热能。该设备将在高峰时段使用斯特林电机发电，热损失将用于加热用于取暖或热水的水基质。如果需要，该装置还将具有将能量反馈到电网的能力，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.
