“…In a modelling study of an off-grid hybrid diesel/PV/battery system in rural India, Sandwell et al find that, at current diesel prices (~$0.8/ litre) and a battery cost below around $250/kWh (or $532/kWh usable capacity owing to an assumed maximum DoD of 47%), it is cost optimal to meet the majority of electricity demand with PV and storage rather than diesel generation (Sandwell et al, 2016). This is associated with a significant reduction in specific emissions from 1056 g CO2/kWh to 373-540 gCO2/kWh (depending on location).…”

A B S T R A C TThis paper presents probabilistic estimates of the 2020 and 2030 cost and cycle life of lithium-ion battery (LiB) packs for off-grid stationary electricity storage made by leading battery experts from academia and industry, and insights on the role of public research and development (R&D) funding and other drivers in determining these. By 2020, experts expect developments to arise chiefly through engineering, manufacturing and incremental chemistry changes, and expect additional R&D funding to have little impact on cost. By 2030, experts indicate that more fundamental chemistry changes are possible, particularly under higher R&D funding scenarios, but are not inevitable. Experts suggest that significant improvements in cycle life (eg. doubling or greater) are more achievable than in cost, particularly by 2020, and that R&D could play a greater role in driving these. Experts expressed some concern, but had relatively little knowledge, of the environmental impact of LiBs. Analysis is conducted of the implications of prospective LiB improvements for the competitiveness of solar photovoltaic + LiB systems for off-grid electrification.

Abstract:The lack of access to electricity of more than 1.1 billion people around the world remains a major developmental challenge and Goal 7 of the Sustainable Development Goals (SDG) as well as Sustainable Energy for All (SE4ALL) have set a target of universal electrification by 2030. Various studies have identified mini-grid-based electrification as a possible solution. There is a growing body of literature available now that has explored the feasibility, practical application and policy interventions required to support mini-grids. Through a review of available literature, this paper explores whether mini-grids can be a solution for the base of the pyramid (BoP) market and the challenges faced in deploying mini-grids in such markets. Interventions to support the mini-grid deployment are also discussed. The paper finds that the mini-grids are targeting the BoP market but the business is not attractive in profitability terms and requires financial support. Lack of regulatory clarity and non-coordinated policies affect the financial viability of projects, which requires careful support. Mini-grid electrification has hardly been embedded in rural development agenda and hence they have not contributed significantly to livelihood generation. Careful realignment of policies, regulatory frameworks and support systems can better support mini-grid deployment in developing countries.

“…Although there are various new types of battery, the only options that are currently cost-effective are lead-acid batteries. 64 Used batteries must be appropriately recycled; the improper disposal of lead-acid batteries has significant environmental impacts and can contaminate local water supplies. Unfortunately, more often than not there is no recycling or safe battery disposal process in place for small communities in South and Southeast Asia.…”

A Road Map for Small-Scale Desalination: An overview of existing and emerging technology solutions for cost-efficient and low-energy desalination in South and Southeast Asia

Asia is one of the hardest hit areas in the world in terms of intrusion of saline groundwater. In the near future, sea-level rise will cause further saltwater intrusion into water resources, while an increasing number of water control structures will increase river salinitythreatening fresh water supplies for drinking and livelihoods, irreversibly impacting people's lives and livelihoods. Desalination technologies typically require high energy inputs, as well as specialized maintenance procedures, to function sustainablyrendering them inappropriate for water production in low-income areas. The focus of this paper is the development of a 'Road Map' for scalable, low energy-input solutions for small-scale desalination.
