In this study, we hypothesized that planting spacing in forest plantations affects the carbon storage above-belowground, soil carbon, and elemental composition
Therefore, preparing thermal energy storage wood (TESW) is important for developing energy-efficient buildings. Few single phase-change materials can meet the temperature regulation requirements of interior areas, while eutectic mixtures can be adjusted to the appropriate temperature interval by changing the ratio of different components.
Wood energy has been a regular topic at the annual Timber Committee Market Discussions since 2002. It featured as the major topic of the Policy Forum in 2003, the same year that it entered the agenda of the annual meeting of the Joint Working Party on Forest Economics and Statistics.
There are two principal differences between the way a supply of biomass must be handled compared with mains gas: A sufficient reserve of biomass fuel must be stored at the point of usage. Delivery must be arranged and scheduled. Compared with heating oil, there is the fact that biomass is of significantly lower energy density and so a larger
The energy storage terms for a mixed forest environment at the Petawawa National Forestry Institute, Chalk River, Ontario, have been examined for the 1985 summer months (May–August). The soil heat flux is the largest contributor to the total storage. Sensible heat storage in the canopy is of greatest significance during dry, clear
In addition, self-luminous wood can absorb ultraviolet and visible light from lighting source and natural light, and emit green light in the dark for 11 h, which can be used for light energy storage to reduce energy consumption. More interesting, the addition of LAL particles can improve the thermal conductivity of self-luminous wood composites.
Transparent wood enhanced with phase change heat storage function could effectively utilize sunlight and thermal energy to further improve energy efficiency. In this study, epoxy resin compound with phase change materials polyethylene glycol (PEG) were impregnated into the delignified wood to prepare novel transmittance energy
There are now four ways to release the energy stored in biomass: burning, bacterial decay, fermentation, and conversion to gas/liquid fuel. Burning: Burning of the biomass will
OFFICIAL Native Forest Wood Waste in the Renewable Energy Target DCCEEW.gov 5 OFFICIAL d. sawmill residue e. biomass from a native forest that meets all of the requirements in subregulation (2). Native forest biomass as referred to in this paper is the
A biological carbon sequestration strategy, hereafter termed Wood Harvest and Storage (WHS) has recently been proposed in which forest is actively
Wood is very versatile and easy to store. It can therefore play an important role in the energy transition. Compared to today, up to a third more energy could be
Energy required to deliver biomass to final consumers represents between 0.4% and 1.8% of the primary energy contained in the forest wood, and less than 5% in the case of manure. Some forest wood chains attain the maximum break-even transport distances after 36 km only, whereas others could reach over 400 km.
Besides forest carbon sequestration and storage, wood-based products can provide significant carbon storage. Wood products may also be used to substitute for fossil-fuel-intensive materials, products and energy (Nabuurs et al.
The Activity Group on Sustainable modern wood energy development, led by FAO, promotes the adoption of sustainable management practices and efficient technologies for the production and use of modern wood energy and improved solid biofuels that can replace traditional energy forms, while reducing greenhouse gas
1. Introduction The use of biomass as sustainable energy source has been subject of debate over the last years, both in the public (Van Hilst et al., 2017) and scientific domains (Agostini et al., 2019).Main criticisms are related to the denominated "carbon debt", 1 the increase in prices for wood-based materials, and the potential displacement or
We thus examined how climate change impacts forest C storage across 24 independent ''forest type groups'' defined in the US FIA via a RF-based tree species niche model. We found that around 71%
Publications Recent publications Sustainable management of Miombo woodlands – Food security, nutrition and wood energy The Miombo woodland is a vast African dryland forest ecosystem covering close to 2.7 million km2 across southern Africa.The woodlands
Bits of trees can make and store energy for us to use. This cellulose and lignin could lead to greener electronics. Within these trees'' wood are materials that could lead to cleaner, greener electronics. Santiago Urquijo/Moment/Getty Images Plus. By Katie Grace Carpenter.
Concerning the tropical condition, the gains and losses of MC were more pronounced than reported by Sikanen et al. [18] studying energy wood forest storages in Finland who obtained the maximum and
Carbon dioxide (CO 2) is the main greenhouse gas causing global warming. The combustion of fossil fuels produces around 21.3 billion tonnes of CO 2 per year. It has been estimated that natural processes can only absorb about half of that amount, so there is a net increase of 10.65 billion tons of atmospheric CO 2 per year.
3) Historical data reveals that China''s forest carbon storage stood at 5.89Pg in 1949, dipped to a nadir of 4.90Pg by the late 1970s, and subsequently rose to 8.69Pg by the time of the 9th NFI

Storage is an important component in securing the supply chain for forest fuels, but can result in substantial dry matter and energy losses that reduce the economic value of the material. This study examined fuel quality and amount of recovered energy during storage of forest-residue chips stored in a full-scale pile and the effect of covering
According to our model, wood production for energy results in a significant reduction of carbon storage levels in forests (by 46% to 77% in 2050 from the

Technical drying of wood chips by active ventilation is often applied, i. a. to reduce dry matter and energy losses due to decomposition during storage. However, wood chips are often dried to very low moisture contents (MC) of below 10–15 % (moisture mass fraction on wet basis), that might lead to a waste of drying energy.
Cell walls in plants, particularly forest trees, are the major carbon sink of the terrestrial ecosystem. Chemical and biosynthetic features of plant cell walls were revealed early on, focusing mostly on herbaceous model species. Recent developments in genomics, transcriptomics, epigenomics, transgenesis, and associated analytical techniques are
Wood is widely used in human life as a natural renewable material. Improving the temperature regulation function of wood is of great significance to reduce the consumption of fossil energy and promote the construction of a low-carbon society. In this study, a phase
First, CO2 sequestration in forests and subsequently in harvested wood products, is an effective strategy to offset a part of national CO2 emissions, resulting
Energy wood refers to wood harvested from forests and used for energy generation in power plants and households. Using wood-based material in energy production is an important element of the renewable energy sources portfolio. Energy wood can be used as a substitute for fossil fuels. When sustainably sourced, energy wood has a significant
Using wood for power generation necessitates a more efficient production chain in the various steps: harvesting, forwarding, storage, chipping, transport, and conversion systems. In this context, the moisture content (MC) of wood can impact the harvesting operation, the volume to be chipped, the transportation of raw materials, the
Huge amounts of carbon being sequestered in forest ecosystems make them an important land carbon sink at the global scale. Their ability to withdraw carbon dioxide (CO2) from the atmosphere, whose concentration is gradually increasing due to anthropogenic emissions, renders them important natural climate-mitigation solutions.
By harvesting trees, the carbon balance of forest ecosystems seems unchanged; thus, the energy represented by the emissions from harvested wood is
