The Punjab Energy Development Agency has released a draft green hydrogen policy aiming to achieve a green hydrogen and ammonia production capacity of 100 kilo tonnes per annum by 2030. The policy proposes extending incentives under the existing “Punjab Industrial and Business Development Policy 2022” to new green hydrogen and …
Biomass based power generation is one of the promising renewable options. This article reviews the status and potential of biomass based power for India.
After harsh contention the conservative and social democrats forming the fractious German government have agreed on a revision of the Renewable Energy Sources Act that regulates clean power promotion. Dispute was sharpest over provisions of photovoltaics.
Concerns for energy conservation, developing sustainable energy sources and interest towards national energy security benefits combined with growing environmental pollution is necessitating the search for renewable energy sources. Of the renewable energy sources, biomass is highly flexible and the least cost alternative. The use of biomass feed stocks in energy …
Nitrogen (N) is essential to the survival of all life forms and often limits productivity, decomposition and the long-term accumulation of carbon in terrestrial ecosystems. Soil and vegetation are the respective primary and secondary sinks for N in terrestrial ecosystems. Litter production determines the amount and quality of N returned …
Mine spoils consist of overburdened dumps of haphazardly, mixed consolidated and unconsolidated material. Mine spoils are nutritionally and microbiologically impoverished habitats. Natural restoration of mine spoil is a slow process. Afforestation of mine spoils with fast growing tree species accelerates the revegetation process and fulfils the restoration goal.
The role envisioned for liquid biofuels for transport has come under increased scrutiny in the past year or two, due to the potential social and environmental impacts associated with scaling up biofuels production and use from its low level
As the United States seeks to reduce greenhouse gas (GHG) emissions from motor vehicles and to lessen its dependence on imported oil, biofuels are gaining increasing attention as one possible solution. This paper offers an introduction to the current state of play for biofuels: the technologies used in their production, …
Litter production and decomposition are important in nutrient cycling and detritus based food chain. Litter production in mangrove varies widely with species, forest type, stand age, geographical location and environmental parameters.
Climate change will have a disproportionate impact on poor developing countries - compared to the expected net effects in developed regions - due to a combination of more severe climatic impacts in areas that are already vulnerable today, coupled with inadequate resources, technology and organizational capacity to adapt to them. …
With about 20 biomass-based power projects generating 183 MW at Sirsa, Panipat, Karnal, Hisar, Fatehabad, Bhiwani, Nilokheri, Jagadhari, Khanesar and Dabwali, the people of Haryana can be assured of lesser power cuts. As the projects are being set up at the sites of the load centres, the power supply is …
The Amazon Basin experiences severe droughts that may become more common in the future. Little is known of the effects of such droughts on Amazon forest productivity and carbon allocation. We tested the prediction that severe drought decreases litterfall and wood production but potentially has multiple cancelling effects on belowground …
Long-term monitoring of distributed, multiple plots is the key to quantify macroecological patterns and changes. Here we examine the evidence for concerted changes in the structure, dynamics and composition of old-growth Amazonian forests in the late twentieth century. In the 1980s and 1990s, mature forests gained biomass and underwent accelerated …
Pradip Sen Alternative and green energy resources like hydropower, wind power, biomass, fuel cell, solar PV, geothermal and other unconventional resources constitute a high potency growth segment. In India, green energy generation has been on the priority list for quite some time, but its potential is yet to be realised …
until now, it was believed that methane, from cattle dung and paddy cultivation, was the second biggest contributor to global warming after carbon dioxide. A recent review says soot is the second biggest contributor. Soot has 60 per cent of the effect of carbon dioxide on global warming, and China …
Tree leaves Corn stover Wood chips Poultry litter pellets Farmers can be trained to make biochar from agricultural waste depletion of organic matter in the soil and use of chemical fertilizers are increasingly becoming problems for farmers. Taking their cue from agricultural practices in the Amazon basin, scientists at Delaware …
Sustainability of biomass as an energy source will be vital if Ireland achieves its renewable energy targets, a conference in Dublin has heard. It is claimed that Ireland needs to gather together significant quantities of biomass in order to hit its targets for 2020 and an EU-wide scheme for determining …
In a recent paper in the journal Carbon Balance and Management (vol 3, p 1), Ning Zeng, an atmospheric scientist at the University of Maryland in College Park calculated that if we buried half of the wood that grows each year, in such a way that it didn't decay, enough …
