![]() The conversion technologies developed in the research programme improve the efficiency and CO 2 balance of such applications, but not all are ready for the market.įurthermore, electricity can be generated from energy wood in combined heat and power plants, which would be the next best use, especially in winter, to bridge the winter electricity gap. This helps the CO 2 balance and compensates for other emissions, such as those from agriculture, which are unavoidable. The waste heat and CO 2 produced during conversion should be captured and used. Or it can be used to produce gaseous and liquid fuels - including for aircraft. ![]() In industry, wood can be used to generate high-temperature process heat, for example in the form of steam. This is not optimal, the authors warn.įor maximum energy production and CO 2 savings, wood should be used differently on a larger scale than it is today. ![]() At present, however, 95 per cent of the valuable energy wood is used to generate heat for heating rooms. Instead, it should first be used to make houses and furniture, chipboard or insulating materials before it is burned. The researchers suggest the following for more efficient use: From a climate protection perspective, wood should not go straight from the forest into the oven, if possible. "Wood as a valuable but limited source of energy requires efficient use," emphasises Oliver Thees from WSL, who played a leading role in the report. The most untapped potential (5 to 10 PJ) remains in forest wood. This share could - economically and ecologically sustainable - increase by a maximum of one third (14 petajoules), calculated the WSL bioenergy experts.Įnergy wood can originate directly from the forest and open land, but it can also be residual wood from carpentry and sawmills or wood that has already been used (referred to as waste wood). That is slightly more energy than the city of Zurich needs in a year. It summarises the results of the Federal Government's multi-year energy research programme "Biomass for Swiss Energy Future" (SCCER Biosweet), which involved up to 15 research groups and dozens of industry partners.Ĭurrently, wood energy accounts for about 5 per cent of the total final energy consumption in Switzerland, namely about 40 petajoules (PJ) per year. The authors of the "White Paper Wood" emphasise that "energy wood is of greater importance than its comparatively low potential would suggest". They also investigated how bioenergy should best be embedded in the Swiss energy system. ![]() Researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL, the Paul Scherrer Institute PSI and other institutions have calculated the energy potential of Swiss wood and further developed technologies for combustion and conversion into electricity and fuels. Last but not least, it can bridge gaps in solar and wind energy production, as it is available all year round. Wood can be produced CO 2 neutrally, used several times as a material, transported and stored in various forms, and used as heat, electricity and fuel.
