Environmental leader, Sweden hosts World Bio Energy conference.

World Bioenergy--Clean Vehicles & Fuels Conference 2009 is a special joint partnership between two leading international events and the Swedish Energy Agency. Set to coincide with the Swedish EU presidency, it will be held in Stockholm. The World Bioenergy international conference and exhibition on biomass for energy, is organized by the Swedish Bioenergy Association SVE-BIO and Elmia AB in Jonkoping.

Sweden's role as a pioneer in alternative fuels is reflected by the country's royal family which has long championed the causes of climate change and environmental issues. It is therefore not surprising that the World Bioenergy--Clean Vehicles & Fuels conference and exhibition held from 16-18 September 2009 will be inaugurated and patronized by His Majesty King Carl XVI Gustaf of Sweden.

Sweden is one of the leaders in the global race to find alternative and renewable energy sources. Its innovative strategies have been largely due to the country's lack of fossil fuel resources.

The European Union Renewable Energy and Climate Change package which was agreed upon in December 2008, proposes that each EU member increase its share of renewable energy by 2020. Sweden's self-imposed target is 49%--the highest in the EU.

After the oil crisis in the 1970's, Sweden decided to break the link between economic growth and increased greenhouse gas emissions by switching to renewable energy.

Sweden's GDP grew by 48% between 1990 and 2007. During this period greenhouse gas emissions decreased by 9% while the use of bioenergy increased by 79%, from 67 TWh to 120 TWh, accounting for just over 28% of the Swedish utilized energy demand.

The 2008 World Bioenergy conference hosted 200 exhibitors which attracted 5700 visitors. Last year's trade fair and conference differed from the previous World Bioenergy events because it emphasized the fact that bioenergy is not just a climate project but a necessity for global growth.

The Clean Vehicles and Fuels S European symposium and exhibition on sustainable transport systems is organized by the City of Stockholm, the Swedish Gas Association, the Swedish Biogas Association, Hydrogen Sweden, BioAlcohol Fuel Foundation BAFF and the Swedish Electric and Hybrid Vehicle Association SWEVA. The most recent Clean Vehicles & Fuels was held in 2007 and the event attracted 400 delegates from 28 countries.

"Climate change, security of supply and demonstration of ways to reach EU 2020 renewable energy and emissions reduction targets, are all issues likely to dominate the presidency agenda. In this respect Sweden serves as role model, being a world renowned leader in pioneering and implementing renewable energy system solutions," say the event's organizers. "Through hosting a top level EU energy round table meeting during the event, it is this leadership role that the Swedish Energy Agency intends to further develop."

Automotive Industries (AI) spoke with three of Sweden's leaders in environmental strategies; Gustav Melin, president of the Swedish Bioenergy Association, Svebio, Gustaf Landahl, Head of Department Environment and Health Administration City of Stockholm and Kent Nystrom, President of the World Bioenergy Association (WBA).

AI: What are the socio-economic drivers behind the implementation of bioenergy projects in Sweden?

Melin: The key drivers behind Swedish bioenergy development have mainly been political. After the first oil crisis in 1973, and even more after the second oil crisis in 1979, Swedish politicians decided to reduce the country's dependency on oil. At that time we had an oil dependency of 70%, and it was all imported. In the seventies and eighties, we had a raging public debate over nuclear energy, and a decision was made to decommission nuclear power by 2010. This lead to an active search for alternative energy sources. Bioenergy, including wood fuels, peat and waste was the first choice as Sweden has abundant bioenergy resources and a well developed forestry industry.

The first step was to convert use of fossil fuels, and particularly oil in district heating, and to expand district heating to more cities and towns. Today more than half of all space heating in Sweden is based on district heating, and two thirds of district heating is fired by biomass fuels. The next step was support for biopower production and introduction of green electricity certificates stimulating more combined heat and power (CHP) along with wind power.

The third step was biofuels for transport, supported by tax exemptions for renewable fuels and mandatory legislation for filling stations over a certain annual fuel sales volume to provide at least one alternative fuel for consumers. This has helped fast track the E85 distribution infrastructure.

Today 28% of the end-use of energy is bioenergy whereas the total share of renewable energy in the Swedish energy mix is 44%. The other big renewable source is hydropower.

The main political incentives used in this process are high carbon tax on fossil fuels (Polluter Pays Principle), green certificates to stimulate renewable electricity, tax exemptions for biofuels in transport and, at times, tax rebates for consumers to stimulate market adoption of renewable technologies such as wood pellet burners to replace oil fired domestic heating. Investment grants and support for research and development are available in some cases.

AI: Tell us about the integration of energy recovery into solid waste management regimes.

Melin: In the early nineties, Sweden adopted the waste hierarchy of first reusing, then recycling and finally using the remaining waste for energy (power and heat). The producers have a primary responsibility to recycle (glass, paper, metals, packaging, electronic equipment, etc).

Landfill has been prohibited for combustible waste since 2003. Household waste can either be sorted and the biodegradable fraction used for biological recycling (biogas or compost production), or household waste can be used for heat and power production. Incineration without recovery of energy is not done. Landfill sites are now only used for certain kinds of industrial wastes. Recycled wood, demolition wood, and wood waste from parks and gardens are important fuels for the district heating and CHP plants. Today there are around 30 large heating plants, most of them are combined heat and power plants (CHPs), using municipal waste for energy. We consider the emission problems with waste combustion as solved. The emissions of dioxins are only a fraction of what they used to be, due to improved combustion technology and flue gas cleaning.

AI: What is the impact of international trade in bio-fuels? How can countries secure a sustainable supply and demand of these fuels?

Melin: In our view the potential to produce bio-fuels is very large in both temperate climates and sub-tropical and tropical regions. There are vast areas of agricultural lands that are poorly used. In industrial countries we have large areas of set-aside land and fallow land. In many tropical areas we find land used for extensive grazing, or agricultural areas with very low productivity. Biomass for biofuels holds great potential for the development of agriculture, higher incomes for many countries, and substitution of fossil oil imports and reduced oil dependency. Trade in biofuels, both liquid and solid (such as wood pellets) will grow fast in the coming years. These fuels will become important commodities in international trade, and we need to develop standards for them.

Certification of sustainability should be done on a global scale, to be implemented by the market actors. Such an initiative has been taken in ISO--the International Standardization Organization. It is important that both consumers and producers are engaged in this process. Parallel to this process we have to work for better protection of rainforests and other areas of high natural conservation values. Sustainability criteria and environmental protection measures have to apply equally to bio mass used for different purposes--for food, feed, fiber and raw materials--as well as for all energy sources.

AI: Tell us about the emergence of bio-refineries--how will the co-production of fuels, chemicals, power and materials evolve?

Melin: It is important that excess heat from bio-refineries can also be used for district heating or other purposes to ensure good total economy and energy balance. We see a number of developments. Pulp and paper industries today can produce heat and electricity, plus solid fuels, and substitute all use of fossil fuels in their processes. They can, in fact, be "net exporters" of energy for electricity, heat, solid, liquid and gaseous biofuels. One of Sweden's largest pulp factories will reach this stage in the near future.

We also see the combined use of energy, raw materials and residues by combining heat and power plants with ethanol factories and biogas production. Such a combination already exists in Norrkoping, and there are plans for more. In northern Sweden, in Sveg, the basis for the combination is a wood pellet factory. Ethanol production, power production and district heating will be added. To enable the use of excess heat, greenhouses for vegetables and flowers are also planned. It is of course hard to foresee which solutions will dominate and most likely different combinations and applications to suit the specific locality and conditions.

AI: How do you see the development of the market for clean vehicles? How can developing nations be part of this growth?

Landahl: We have seen a development from flexi-fuel (petrol/ ethanol) and bi-fuel (petrol/gas/biogas) cars to biofuel hybrids or biofuel plug-in hybrids combining renewable fuels with high efficiency. We see higher levels of "low blend" both in petrol and diesel in the coming years, and developing markets for high-blends, both ethanol and biodiesel. In Sweden there is a renewed interest in biogas as a vehicle fuel with the simultaneous expansion of biogas production, capacity, expansion of refueling and distribution points and an increased range of both private and commercial vehicles in the marketplace.

An interesting development is ethanol for heavy trucks and using diesel technology and electric hybrid potential in plant machinery such as forest forwarders.

Pure battery electric vehicles are coming into the marketplace and, as a result, new strategic alliances or business models between vehicle manufacturers and utilities are developing. It is important to combine the energy efficiency of electric motors with the good climate gas efficiency of biofuels to reach maximum reductions of climate gas emissions. To reach this we also need more renewable electricity production.

One major problem is that many of these new technologies are expensive. The investment cost for the vehicles will go up, while the cost for the fuel will be reduced in the long run. This can be a major obstacle, particularly in developing nations. We need to pay more attention to reducing cost of the new technologies. From our experience, the power of public procurement is a very effective driving force towards sustainable transportation.

AI: What are the aims of the REN Alliance and what is the World Bioenergy Association's role within this alliance?

Nystrom: The overall goal of the International Renewable Energy Alliance (IREA) is to promote policies that enable the increased use of renewable energy through collaboration, removal of market barriers, identifying and promoting successful implementation strategies, developing markets and improving business conditions.

In 2008, the World Bioenergy Association (WBA) was formed in an effort to provide a wide range of participants in the bioenergy sector including national and international bioenergy associations.

It was formed to address a number of issues including certification, sustainability, standardization, bioenergy promotion, and the debates about bioenergy's impact on food, land-use, and water supplies. For a number of these issues working groups have since been set up.

The WBA strongly believes that we can achieve more together than we can individually and we are delighted to join the REN Alliance. We consider this an opportunity to further strengthen the important role of bioenergy as part of a worldwide renewable energy system. Not least, within the emerging areas of biofuels for transportation.

Having all global renewable energy associations working together helps ensure the security of supply as well as several general environmental benefits. When we act together in the REN Alliance we can demonstrate the powerful potential of renewable energy, correct false information and give a positive picture of renewable energy based on true facts.
