“…Gasifiers convert biomass into so-called producer gas, which has a higher energy density and is easier to handle than traditional biomass. The gas can be used to deliver heat or electrical power efficiently (Larson and Kartha, 2000). India produces an estimated 600 million tonnes of agricultural residues per annum.…”

This article argues the need for strategic reorientation with regard to the technological advancement of developing countries. The continued relevance of incremental capability‐building strategies in manufacturing is questioned by: (i) the emergence of new knowledge areas, some of which require closer links with science; (ii) recognition that past strategies have not solved the poverty problem; and (iii) unprecedented environmental problems that cannot be solved by existing Western technologies alone. A more pluralist approach is recommended, with increased attention to creative innovation capabilities. Cases of innovations in information communication technology, health and energy show potentially large economic and social impacts, but also highlight systemic obstacles to their realisation.

“…Some argue that degraded lands could be targeted with these plantations, others are concerned about social and environmental conflicts that may arise if/when dedicated plantations come to compete with food production for agricultural lands. For various perspectives on these issues, see Hall et al (1993); Carrere and Lohman (1996); Azar and Larson (2000); Larson and Kartha (2000); Victor and Ausubel (2000) and Azar (2004).…”

Carbon Capture and Storage From Fossil Fuels and Biomass – Costs and Potential Role in Stabilizing the Atmosphere

The capture and storage of CO 2 from combustion of fossil fuels is gaining attraction as a means to deal with climate change. CO 2 emissions from biomass conversion processes can also be captured. If that is done, biomass energy with CO 2 capture and storage (BECS) would become a technology that removes CO 2 from the atmosphere and at the same time deliver CO 2 -neutral energy carriers (heat, electricity or hydrogen) to society. Here we present estimates of the costs and conversion efficiency of electricity, hydrogen and heat generation from fossil fuels and biomass with CO 2 capture and storage. We then insert these technology characteristics into a global energy and transportation model (GET 5.0), and calculate costs of stabilizing atmospheric CO 2 concentration at 350 and 450 ppm. We find that carbon capture and storage technologies applied to fossil fuels have the potential to reduce the cost of meeting the 350 ppm stabilisation targets by 50% compared to a case where these technologies are not available and by 80% when BECS is allowed. For the 450 ppm scenario, the reduction in costs is 40 and 42%, respectively. Thus, the difference in costs between cases where BECS technologies are allowed and where they are not is marginal for the 450 ppm stabilization target. It is for very low stabilization targets that negative emissions become warranted, and this makes BECS more valuable than in cases with higher stabilization targets. Systematic and stochastic sensitivity analysis is performed. Finally, BECS opens up the possibility to remove CO 2 from the atmosphere. But this option should not be seen as an argument in favour of doing nothing about the climate problem now and then switching on this technology if climate change turns out to be a significant problem. It is not likely that BECS can be initiated sufficiently rapidly at a sufficient scale to follow this path to avoiding abrupt and serious climate changes if that would happen.

“…This is possible through the increased participation of sustainable energy in relation to the total electricity consumption in Brazil, substituting, the construction of power plants using fossil fuels. Studies show that long-term use of biomass energy is more advantageous than employing the land for carbon sink forests [16].…”

Abstract. Brazil has historical concerns about renewable sources of energy, mainly because it is the largest tropical country in the world, receiving intense solar radiation, which is the basis of biomass production. In addition, the country has exceptional soil and climate conditions and great biodiversity. Agriculture and livestock activities are very representative in the Brazilian economy and produce usable biomass, which entail renewable sources of energy and the need for residue management. In this context, biogas represents a basic energy source; it is generated via planned treatment of animal, human and industrial wastes. This has two main results: a) the generation of electric, thermal, and vehicular (biomethane) energy; and b) the reduction of greenhouse gas emissions and resultant mitigation of global warming. This paper assesses agricultural biogas projects being developed by Itaipu Binational, the second largest hydroelectric power generation company in the world, which has diversified its energy production from hydropower into other renewable sources such as biogas. In addition to promoting environmental and economic benefits, it promotes local social development, since the process for biogas production constitutes and sustains a relatively complex supply chain, requiring local skilled labor, technical and scientific support, and environmental awareness in the population. We conclude with implications of the Itaipu biogas case example for a range of other contexts.
