项目摘要

This project will take rice straw, which is currently a waste material creating environmental problems in intensive rice systems across South and South-East Asia, and demonstrate the feasibility of converting it to a useful energy resource. The research will focus on addressing the very challenging physical and chemical properties of rice straw as an energy feedstock in a way that yields direct benefits for local communities. Barriers to be overcome include logistics, social integration, technological and economical challenges and institutional support. With such a multi-disciplinary suite of obstacles, a similarly multi-disciplinary team has been assembled to try to negotiate them. Wheat straw physiology and bioenergy technology experts from the SUPERGEN bioenergy hub have teamed up with rice straw experts, engineers, social scientists and extension staff from IRRI to form the core research team. This team will work together in partnership on 5 work packages that will effectively transfer knowledge between the partners to address the obstacles to sustainable development of energy from waste rice straw. These include:1. Understanding the rice straw and the specific challenges (technical, economic and social) associated with using it for energy purposes2a. Evaluating the technical and economic performance of different technology options for delivering energy from rice straw - carrying out conversion trials of rice straw in the Philippines using different conversion technologies (e.g. gasification, combustion and anaerobic digestion) to develop projections of how a whole system based on these different conversion options would perform at different scales across a range of technical and economic criteria e.g. capital cost installed, payback time, break even price of heat generated etc.2b. Using stakeholder engagement to identify the technical and non-technical barriers associated with energy conversion of rice straw, including issues such as viable business models for project development3. Quantifying the environmental impact of the most promising conversion options, including crucially the greenhouse gas benefits4. Understanding the energy needs and technology preferences of local communities via focus group discussions, that involve not just farmers (with a feedstock focus) but also their households (as end users with cooking needs, electricity, food storage etc) to account for whole community concerns in a gender-sensitive way. Rice millers, village leaders and policy makers will also be involved in discussions to gain a wider range of perspectives that will inform the study.5. Enabling development of the rice straw-energy technologies by engagement with a variety of local and international stakeholders and addressing the key issue of development risk by demonstrating technology viability at a facility to be built at IRRI's Experimental Station.This represents a co-ordinated programme of activities focused on better understanding the particular issues associated with rice straw conversion and addressing these to show what works and what does not. This is a critical step in solving the major environmental and health issue of rice straw burning across Asia, whilst bringing energy access benefits for local communities. The UK partners gain from stretching their understanding of plant performance with an unusually challenging feedstock, which may also have implications for other feedstocks, and by deepening understanding of the socio-political context in developing countries. IRRI benefits from improved understanding of the scientific and engineering challenges posed by conversion of rice straw and how to overcome them. Local communities benefit from reduced environmental hazard and clean energy access. The wider global population benefits from reduced greenhouse gas emissions from rice production and energy use.

该项目将采用稻草，这是目前在南亚和东南亚的密集稻系统中产生环境问题的废料，并证明将其转换为有用的能源的可行性。这项研究将着重于解决稻草作为能量原料的物理和化学特性，从而为当地社区带来直接利益的方式。要克服的障碍包括物流，社会融合，技术和经济挑战以及机构支持。凭借如此多学科的障碍套件，已经组装了一个类似的多学科团队来试图谈判他们。 SuperGen Bioenergy Hub的小麦稻草生理学和生物能源技术专家已与IRRI的稻草专家，工程师，社会科学家和推广人员合作，组成了核心研究团队。该团队将共同合作与5个工作套餐合作，这些工作包将有效地转移合作伙伴之间的知识，以解决从废米稻草中可持续发展能源的障碍。这些包括：1。了解稻草及其用于能源目的的特定挑战（技术，经济和社会）2a。使用不同的转换技术（例如气化，燃烧和厌氧消化）评估菲律宾在菲律宾进行稻草的转化试验的不同技术选项的技术和经济性能 - 开发基于这些不同转换选项的整个系统如何在技术和经济范围内的不同尺度上执行整个系统的预测。安装了资本成本，回报时间，产生的热量等于2B。利用利益相关者的参与来确定与稻草能量转化相关的技术和非技术障碍，包括诸如项目开发的可行业务模型等问题3。量化最有希望的转换选项的环境影响，包括至关重要的温室气体益处4。通过焦点小组讨论了解当地社区的能源需求和技术偏好，这些讨论不仅涉及农民（有原料焦点），还涉及他们的家庭（作为烹饪需求，电力，食物存储等的最终用户），以性别敏感的方式解决整个社区的关注。赖斯磨坊主，乡村领导人和政策制定者还将参与讨论，以获得更广泛的观点，这些观点将为这项研究提供信息。5。通过与各种本地和国际利益相关者进行交互，通过在Irri的实验站中展示技术可行性来实现稻草能源技术的开发，并通过在设施中展示技术的可行性来解决主要问题。这代表着一个协调的活动计划，该计划的重点是更好地理解与稻草的转换和解决这些可行的稻草对转换和解决方案的特定问题。这是解决整个亚洲稻草燃烧的主要环境和健康问题的关键一步，同时为当地社区带来了能源访问益处。英国的合作伙伴通过通过异常具有挑战性的原料来扩展对植物绩效的理解，这也可能对其他原料产生影响，并加深对发展中国家社会政治环境的理解。 IRRI受益于对稻草转换以及如何克服稻草构成的科学和工程挑战的了解。当地社区受益于减少环境危害和清洁能源通道。更广泛的全球人口受益于稻米生产和能源使用的温室气体排放量减少。
