SBIR Phase II: Pneumatic Energy Storage with Staged Hydraulic Conversion for Low Specific Cost Renewables Support

该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。这个小型企业创新研究第二阶段项目将开发和评估50千瓦300千瓦小时新型储能系统的Beta原型。目前还没有一种储能技术能够在中等容量范围内(100kWh-10MWh)提供低比成本、高能量密度和长寿命运行。可再生能源供应商(如风能和太阳能)、商业和工业消费者以及公用事业公司存在着特别的机会，提供能力巩固、消费平滑、能源套利和电力监管等服务。可持续性X打算开发、制造和营销一种颠覆性、成本效益高和可扩展的能量存储设备，该设备将成为风能和太阳能等替代能源激增的使能技术。在通过第一阶段和第一阶段B工作证明了技术可行性后，该公司的第二阶段工作将致力于提高系统往返效率，扩展技术，并最终在客户现场部署Beta系统。低成本、长寿命的能量存储具有广泛影响电网稳定性和可靠性、商业和工业消费能源成本、可再生能源发电机价值和整体市场渗透率的潜力。由于可再生能源组合标准、化石燃料成本上升、公众对气候变化的情绪和其他市场压力，风能的普及率增加，该行业面临许多挑战。这些问题包括但不限于供应的间歇性、发电量预测的误差、监管要求的提高以及输电阻塞。随着风能在能源组合中所占比例越来越大，这些挑战变得更加复杂。能源储存有可能缓解这些整合问题，从而使风电能够以更经济可行的方式得到更大规模的利用。具体地说，风力发电机将能够利用可持续发展公司的储能技术来稳定产能、增加高峰销售并增强辅助服务能力。因此，存储能力不仅对当前的风能生产具有重要价值，而且还应被视为一项使世界能够实现其近期和长期能源管理目标的技术。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Small Business Innovation Research Phase II project will develop and evaluate a Beta prototype 50 kW 300 kW-hr novel energy storage system. No current energy storage technology can provide low specific cost, high energy density, and long lifetime operation in the mid-capacity range (100kWh - 10 MWh). Particular opportunities exist with renewable energy providers (e.g., wind and solar), commercial & industrial consumers, as well as utilities for services such as capacity firming, consumption smoothing, energy arbitrage, and power regulation. SustainX intends to develop, manufacture and market a disruptive, cost-effective and scalable energy storage device that will serve as an enabling technology for the proliferation of alternative energy generation sources, such as wind and solar power. Having demonstrated technical feasibility through the Phase 1 & 1B effort, the company's Phase II effort will be dedicated to improving system round-trip efficiency, scaling the technology, and ultimately deploying a Beta system at a customer site.Low cost, long lifetime energy storage has the potential to broadly impact grid stability and reliability, commercial and industrial consumer energy costs, and renewable energy generator value and overall market penetration. As the penetration of wind increases due to renewable portfolio standards, rising fossil fuel costs, public sentiment surrounding climate change and other market pressures, the industry faces a number of challenges. These include, but are not limited to, intermittency of supply, errors in forecasting power production, increased regulation requirements, and transmission congestion. As wind becomes a larger percentage of the energy portfolio, these challenges are compounded. Energy storage has the potential to mitigate these integration issues, thereby allowing wind power to be utilized on a larger scale in a more economically-viable fashion. Specifically, wind generators will be able to use SustainX's energy storage technology to firm capacity, increase peak sales, and enhance ancillary service capabilities. Storage capacity therefore not only represents a significant value to current wind production, but should also be seen as an enabling technology that will allow the world to reach its near- and long-term energy management goals.
