IFC says green recovery could drive $2.5tn renewables market this decade

The private-sector arm of the World Bank, which claims to leverage $3 of its own capital and $8 from third parties for every dollar invested in its blended finance funds, has attempted to quantify what devoting Covid recovery funds to green investment would mean for emerging economies.

New method to build microgrids based on solar, hydrogen

The use of polymer electrolyte membrane fuel cells as backup power generation in solar microgrids could drive down costs and improve efficiency, according to an international group of researchers. They have proposed a new energy management system that could be ideal for hybrid solar-hydrogen microgrids in remote locations.

The case for distributed solar with storage

Gopal Lal Somani, a former director at the Jaipur-based Rajasthan Renewable Energy Corporation Ltd (RRECL), says distributed solar systems with storage are the key to achieving India’s mission of supplying clean energy at an affordable cost to all. In this article, he dwells on the benefits and techno-commercial feasibility of these systems for the nation.

India re-elected as President of the International Solar Alliance

Launched in November 2015, the alliance aims to collectively address key challenges to the scaling up of solar energy in member countries that fall between Tropic of Cancer and Tropic of Capricorn. The Alliance is now supported by 68 member countries, and a further 20 countries are in the process of becoming members.

The long read: Packing light

Tens of thousands of health facilities in low- and middle-income countries lack reliable electricity, contributing to high rates of maternal mortality. Health workers struggling in near darkness use candles, kerosene lanterns, or cellphones to provide illumination for critical procedures. They ask patients to pay for candles, batteries for flashlights, or kerosene for lanterns – a barrier to health care for women living in extreme poverty. We Care Solar designs and delivers pre-wired compact Solar Suitcases for maternal health care facilities in the developing world. This all-in-one solar+storage solution for childbirth evolved from a doctoral student’s research project, and is being scaled worldwide to ensure that no woman gives birth in the dark.

UK’s Power Roll trials low-cost, flexible solar-and-storage system in Himalayan villages

The system will use an innovative solar film developed by Power Roll that can be manufactured for just $0.03/Watt and deployed on a wide range of non-load bearing buildings, including agricultural and warehouse roofs.

The long read: Advanced lead batteries for microgrids

With demand for cleaner forms of energy and a greater need for flexibility and reliability in the power supply, the role of battery energy storage is critical. Innovation in battery technology is essential to match demand growth and the shift in technical requirements. Predictions of 400,000 MWh of battery storage required by 2025 means that all battery technologies will play a role in contributing to a clean energy future.

The long read: Solar vs. salty drinking water

A solar array – complete with battery storage and remote monitoring and control capabilities – has been transforming brackish groundwater into fresh drinking water in the village of Beyo Gulan in the Somaliland desert since 2018. The installation was developed by Germany’s Phaesun. Its unique combination of low-maintenance electrodialysis desalination with PV saw it pick up an Outstanding Projects award from The smarter E. Phaesun’s Géraldine Quelle and Florian Martini say they are honored by the plaudits, and are readying the system for series production.

IESA proposes a policy framework for energy storage in Electricity Act

Defining energy storage under the Electricity Act could help start ancillary services and frequency regulation through energy storage as a flexible asset. It will also help to enable electric vehicle charging infrastructure, vehicle-to-grid (V2G) concepts and microgrids integration with expanded grid connectivity in the long run, according to the industry body.

Solar will turn vicious water-energy-climate cycle into virtuous loop

The International Water Management Institute is promoting the Solar Irrigation for Agricultural Resilience (SoLAR) initiative to expand the use of solar irrigation systems throughout Bangladesh, India, Nepal, and Pakistan. Proponents of solar irrigation pumps say that they can have a strong positive impact on groundwater.
