Sweden's bio-energy success story

This is a very interesting read.

While people still argue and many are prepared to debate long into Sweden's success in managing its forest resources for  bio-energy, other nations with good biomass resources can learn from Sweden's policies. Malaysia is still rich with forest resources and it doesn't do any harm at all to learn a thing or two from their success.

Today, forest residue is the leading bio-energy source in Sweden, and compared to 3 years ago, bio-energy is now the nation’s biggest energy source.

Growth catalysts

The reasons for the Swedish bio-energy sector’s phenomenal growth include:

  • broad political support 
  • incentives such as the CO2 tax introduced in 1991
  • green electricity certificates introduced in 2003, 
  • tax exemptions for transport bio-fuels
  • Sweden's long-standing tradition of using its natural forest resources
  • good protection and development of forest resources


Contributing factors to biomass development:
  • the rising prices for imported oil, and 
  • the Sweden's debate over nuclear power.

Since late 1970s, Sweden has been seeking new and safe energy sources, evidenced with the initiation of national research into renewable energy. Heating plants had largely switched to biomass, which made up 70% of district heating fuel in 2010.

Biofuels: Swedish cars use high-blend bio-fuels such as E85, which can contain up to 85% ethanol, and biogas, and at the end of 2011 Sweden had more than 200,000 flexi-fuel cars on its roads.

Biomass: Biomass for heating accounts for more than 50% of all space heating in Sweden's housing and service sectors. It is no wonder that there are around 100,000 small-scale pellet heating systems operating in Sweden.

Note: The book that talks about the Swedish bio-energy success story (priced about $12.50) can be found at Svebio.


TheGreenMechanics: Swedish car buyers receive a rebate of SEK10,000 (US$1560 or approximately RM4,850) for buying a green car. We don't have similar cash incentive in Malaysia. But we can surely learn from their environmentally-friendly policies.

Malaysia going the Bio-oil way

During the Palm and Lauric Oils Conference and Exhibition in Kuala Lumpur last week, an exhibitor told that bio-oil, which is derived from biomass, it is a cheaper alternative to depleting fossil fuels. Compared to fuel oil, currently priced at around US$750 (RM2,325) per tonne, bio-oil can be be sold for US$375 (RM1,170) per tonne.


What is bio-oil

Bio-oil is a renewable diesel fuel converted from biomass through process called fast or flash pyrolysis. The fast pyrolysis occurs by heating compact solid fuels in the absence of air (oxygen) at temperatures between 350°C and 550°C for a very short period of time (less than 2 seconds) and then condensing the resulting vapors within 2 seconds.

Big potential for domestic use and export of bio-oil

Malaysia's ambition to produce and use more second-generation biofuel is fast picking up as process engineers embark on converting biomass to liquid fuel via fast pyrolysis.

“Second-generation biofuel, like bio-oil, is more environmentally friendly than biodiesel or bio-ethanol. This is because bio-oil is derived from biomass and this circumvents the food versus fuel dilemma,” said Lipochem Sdn Bhd managing director Koh Pak Meng.

Second-generation biofuels are a realistic alternative to the costlier fossil fuels. This is because bio-oil can be used to heat up water to produce steam to push turbines that generate electricity. This is a valuable means of replacing depleting fossil fuels like petroleum, coal and natural gas.

One can turn a wide range of biomass, for example agricultural waste like oil palm waste, into stable, concentrated bio-crude. This is then refined into bio-oil to replace fuel oil burnt in boilers.

Unlike the current burning of empty fruit bunches in oil mill boilers, Koh said bio-oil plants adopt the fast pyrolysis process, where biomass is heated rapidly to temperatures between 300° Celsius and 550°C at high pressure without any oxygen.

The gases released by the burnt biomass enter a quench tower, where they are quickly cooled and recycled back to the reactor as fuel.

“Bio-oil plants are the way forward as ithey are far more energy efficient and make the industry more carbon neutral,” he told Business Times at the sidelines of the Palm and Lauric Oils Conference and Exhibition, here, yesterday.

Currently, Lipochem’s demo plant in Klang is able to process fiveonnes of dry biomass a day. Koh said this plant, when scaled up 20 times to a commercial size of 100 tonnes a day, will cost around RM30 million.

“The return on investment for a typical 100-tonne-a-day bio-oil plant is around three years. It is a worthwhile investment.”

Koh said bio-oil has many of the advantages of petroleum fuels since it can be stored, pumped and transported. It is currently being combusted directly in boilers, gas turbines, and slow and medium speed diesels for steam and power plants.

“Fuel oil is priced at around US$750 (RM2,325) per tonne while bio-oil can be sold for US$375 per tonne. The price difference itself poses big potential for domestic use of bio-oil as well as for the export market.”
