Fighting climate change with bioenergy may do ‘more harm than good’

Mongabay.com

  • A new study finds land-use like grazing and managing forests for resource extraction may have released more carbon than previously thought. Its results indicate the world’s terrestrial vegetation is currently sequestering less than half its full carbon-storage potential.
  • Of that missing half, the researchers discovered 42 to 47 percent is attributed to land uses that don’t technically change the vegetation cover type. The researchers say that climate change mitigation strategies often focus on reducing intensive land-use like deforestation, with less-intensive uses that don’t change cover type largely overlooked and under-researched.
  • One of these less-intensive uses is managing forests for biomass energy production. Many countries are trying to replace fossil fuels with biomass energy in-line with international climate agreements like the Paris Accord.
  • The researchers warn that strategies developed under the assumption that producing biomass energy doesn’t come at a carbon cost could harm efforts to fight climate change. They urge that in addition to stopping deforestation, the protection of forest functions, like carbon stocks, should be moved more into focus when it comes to land-use and climate change planning.

As nations try to stem emissions to keep the world from warming more than 2 degrees Celsius in line with their commitments towards the Paris Accord, replacing fossil fuels with renewable alternatives is widely seen as a big step in the right direction. A major source of energy oft-extolled as renewable is biomass from trees, which are usually harvested from managed forests either established on land that has already been deforested or planted where forests didn’t naturally grow. But a new study finds land-use like managing forests for biomass production may come at a much higher carbon cost than previously thought.

PetroVietnam on September 6 stated the national oil and gas group has completed the assessment of solutions to deal with unprofitable PetroVietnam-invested projects as per the government’s request. 

He said this was a difficult task because the projects were ‘stuck’ for a long time, while the fiber and biofuel markets were unattractive to investors. Tiếp tục đọc “Unprofitable ethanol projects see light at end of tunnel”

Vietnam vows to revive biofuel plan

Deputy Prime Minister Trinh Dinh Dung has stated at a meeting discussing the implementation of the biofuel development plan that RON 92 petrol will only be available in the market until December 31, 2017.

After that, only E5 RON 92 (biofuel) and RON 95 will be allowed to be produced in Vietnam. Tiếp tục đọc “Vietnam vows to revive biofuel plan”

Những tranh cãi về nhiên liệu sinh học

Minh Đức – Chủ Nhật,  23/7/2017, 16:47 (GMT+7)

(TBKTSG) – Việc sử dụng nhiên liệu sinh học không những không mang lại những thành công như mong đợi mà còn gây ra những rủi ro tiềm ẩn.

Lợi hay hại?

“Chuyển đổi các nguyên liệu sinh khối sang nhiên liệu sinh học là một quá trình thân thiện với môi trường. Vì vậy, khi sử dụng xăng ethanol, chúng ta sẽ giúp làm giảm CO2 trong khí quyển”.

U.S. ethanol makers steer away from fuel, reach for booze

Last update 16:20 | 03/08/2017

A U.S. glut of fuel-grade ethanol has major producers, including Green Plains Inc (GPRE.O) and industry pioneer Archer Daniels Midland Co (ADM.N), pursuing other markets and idling excess capacity in an effort to rebuild sagging margins.

ADM and Green Plains both said on Tuesday they are converting fuel-ethanol capacity into beverage and industrial alcohol production, as well as idling some mills. The announcements follow Pacific Ethanol’s (PEIX.O) decision in June to buy a beverage-grade facility in Illinois, a diversification away from fuel ethanol.

HÀ NỘI — Việt Nam will replace RON 92 petrol with E5 bio-fuel from the beginning of next year.

Accordingly, the supply of RON 92 petrol will be halted in all localities across the country. This was announced by the Government Office following the latest decision passed by Deputy Prime Minister Trịnh Đình Dũng concerning the bio-fuel development project and the roadmap for shifting to bio-fuel mixed with fossil fuels.
