For the first time ever, India is putting out the call for energy storage developers.

The state-run Solar Energy Corporation of India (SECI) is seeking bids for a 750-megawatt solar park at Ananthapuramu in Andhra Pradesh. In order to supplement the massive series of projects, SECI is looking to procure 100 megawatts of storage capacity.

It’s a small step for solar storage in a country that currently has little capacity. But if batteries are regularly added to future tenders, it could add up to a large market, given India’s ambitious solar targets.

The government is planning 20 gigawatts of solar installations over the next few years and 100 gigawatts by 2020 or 2022 — amounting to a $100 billion opportunity for solar, according to Ernst & Young’s renewable energy attractiveness index.

Madhavan Nampoothiri, founder of RESolve Energy Consultants, thinks solar-plus-storage will benefit.

“The opportunity is huge in India, mainly in the rooftop/off-grid space,” he said. “Power outages are rampant in India, and energy storage can help reduce the outages. On the utility-scale projects side, grid balancing and grid integration become increasingly important in order to counter the [intermittent] nature of solar.”

Large companies are preparing to do business in the sector. General Electric recently announced that its energy consulting business was chosen by IL&FS, one of India’s leading infrastructure developers and financiers, to examine the feasibility of integrated wind, solar and energy storage projects at sites in Andhra Pradesh and Gujarat.

“Energy storage can be particularly helpful for integrating variable renewable generation in India since the technical infrastructure and market mechanisms available at the disposal of many other power grids are not yet available in the country,” said Sundar Venkataraman, GE Energy Consulting’s technical director. “As the costs start to come down, energy storage will become an integral part of India’s grid.”

IL&FS, also one of the biggest independent wind power producers in India, last year secured funding from the United States Trade and Development Agency (USTDA) to look into utility-scale integration of wind, solar and storage in India. The grant is part of $2 billion in trade investment that USTDA has earmarked for renewable energy projects in India.

GE’s contribution to the research will include designing a power plant combining wind, solar, energy storage and controls. The company will then look at the costs incurred and build a business plan in order to make the project commercially viable.

At this stage, it is unclear what battery chemistries will dominate in India’s market. It will likely be lithium-ion; however, according to Madhavan Nampoothiri, there will be a place for vanadium redox flow batteries in the longer term.

For example, SunEdison ordered 1,000 vanadium storage systems from Imergy last year for use in solar-powered microgrids in rural India.

Despite its bold plans, India doesn’t have much solar to speak of yet. At the moment, its 3 gigawatts of installed solar account for only 1 percent of the country’s total generating capacity. To put that into perspective, China and Germany already have roughly 40 gigawatts each.

India’s storage sector may depend on how quickly solar scales up in the country.

Energy from waste tech offers on-site scope

Testing is underway of a prototype pyrolysis technology that could extend the range of waste materials that may be used to generate energy.

The Pyrofab system is based on ‘Pyroformer’ technology, developed by the European Bioenergy Research Institute (EBRI) at Aston University in the UK. Using this intermediate pyrolysis process, the tests are determining the potential of different waste materials and residues to be processed into low carbon fuel. Previously hard to treat sources of waste now have the potential to be used as a feedstock to produce low carbon energy and feedstocks being tested include food waste, domestic waste, agricultural waste such as pig manure, industrial waste and even baby wipes.

The Pyrofab converts carbon from organic waste materials to produce carbon neutral fuel and biochar, a commodity that can be used to improve soil.

In addition, the Pyrofab is transportable and can work with existing generation technology meaning waste can be locally sourced.

Professor Tony Bridgwater, Director of the European Bioenergy Research Institute at Aston University, said: ‘The Pyrofab unlocks the potential of waste, producing sustainable carbon neutral bioenergy and biofuels. This has the potential to change a significant liability for businesses and local authorities across North West Europe into a home grown resource, to reduce waste management costs and generate new revenue streams through the derived products.’

Tropical Power has brought online a 2.4-MW biogas power plant in Kenya, reportedly the largest grid-connected biogas plant built in Africa to date.

Located at Gorge Farm, an 800-hectare vegetable farm owned by VP Group, the $6.5 million, two-stage George Farm AD plant will take in waste from the operations as feedstock, around 150 metric tons per day, according to Tropical Power. As a byproduct, the plant is estimated to produce over 35,000 metric tons of fertilizer for use on the farm, displacing an estimated 20 percent of synthetic fertilizer.

The plant was manufactured by German technology supplier Snow Leopard and utilizes a two GE ecomagination qualified Jenbacher J420 biogas engines. Other key component suppliers include IET Siemens for switchgear and transformers, SAR GMBH for instrumentation and control systems, BioG for material handling and Paulmichel for agitators and stirring equipment, according to Topical Power.

The plant took less than 12 months to construct, and Tropical Power estimates its payback period to be around 5 and a half years, on account of grid sales and higher-tariff energy supply to Gorge Farm.

Biojoule Kenya, an Independent Power Producer, will own and manage the facility.

In statements issued when the plant was being commissioned, Mike Nolan, operations director of Tropical Power, said the plant is 50 percent owned and has employed 50 Kenyans in its development. “It will provide a great shop front for other African project developers to view cutting-edge biogas technology and skills,” he said.

Soon to be added to the facility is 10-MW, grid-connected solar PV plant run by Solarjoule.

CAN BIOCHAR AMENDMENTS IMPROVE SOIL QUALITY AND REDUCE CO2? A Climate Change Mitigation Approach through Regenerative Agriculture

A Critical Review Research Paper on Biofuel and bio-energy in sustainable agriculture.

December 12, 2013

Abstract

Variations in rainfall, increased mean surface temperature, persistent drought, reduced soil moisture and nutrient, and crop failures have all been evidently linked to anthropogenic-induced climate change, which impacts food security. Agricultural soils can be used to reduce atmospheric CO2 by altering the physicochemical composition of soil organic matter through biochar soil amendments. This study draws on current literature published online, in peer review journal articles, books, and conference proceedings to assess the implications of biochar soil amendments to enhance soil quality, while reducing atmospheric CO2 concentration. Building on the critical analytical approach, biochar use as soil amendments have been tested to have promising environmental potential, which improves soil quality and quantity thereby enhancing soil moisture status and reduces atmospheric CO2. Analyses of biochar amended soils in terrestrial ecosystems reduces about 12% of the total Carbon (C) emitted through anthropogenic land use change. Biochar amended soil systems are dependable in tracing and quantifying sequestered C and can stay in the soil for thousands of years. The challenge with biochar as soil amendments is the type of biomass that can yield high quality biochar through the pyrolysis process.

Key words: Biochar, amendments, regenerative agriculture, food security, climate change, atmospheric CO2, pyrolysis, Carbon, soil moisture.

Abstract

This project explored the efficiency of the lighting systems at the Academic Commons (AC) at the Goddard Library at Clark University as part of an academic research paper for the Technology for Renewable Energy course taught by Dr. Charles Agosta, Chair of the Physics Department. The study builds on students’ responses to informal and open-ended surveys and electricity energy consumption data from the lighting systems. The data were analyzed using a 2010-MS Excel base calculator to provide descriptive statistics on demographic characteristics and statistical analysis of electricity used via lighting to determine energy cost, savings, CO2 emissions, and offsets by comparing the status quo (CFL lamps) against two hypothetical scenarios. The results indicate that, while the CFL lamps electricity consumption seems efficient in terms of CO2 emissions and cost compared to incandescent lamps, converting the lighting systems to LEDs would reduce CO2 emissions substantially and contribute to Clark University’s goal of zero emissions by 2020 thereby saving cost. The results suggest that Clark University would be saving about $3,687.00/year in lighting systems at the AC, while reducing 18,420 lbs. of CO2/year against the status quo of 147,355 lbs. of CO2/year.
