How much carbon dioxide is produced when different fuels are burned?

Papers obtained by Panorama show Drax took timber from rare forests in Canada it had claimed were “no-go areas”. It comes as the government decides whether to give the firm’s Yorkshire site billions more in environmental subsidies funded by energy bill payers…

All of the 6.5 million tonnes of wood pellets burned by Drax each year are produced overseas. Many come from Drax’s 17 pellet plants in the US and Canada. In 2022, Panorama revealed the company had obtained logging licences in the Canadian province of British Columbia and filmed logs being taken from what the programme said was primary forest to a pellet plant owned by Drax…

Drax says that it decided in October 2023 to stop sourcing wood from old-growth priority deferral areas, and that “work to implement this decision through the supply chain is ongoing”…The burning of wood from old-growth forests contradicts the company’s previous claims. In a 2017 report about sustainability, Drax stated it would not take wood from what it called “no-go areas”. It said: “We do not take from protected forests, old growth or primary forest, sites that have been classified as having a high biodiversity value.”

What did they expect naming it Drax?

Wasn’t Drax also a villain in one of the Bond movies?

“Once more into the breach, dear friends, once more.”

Drax, which operates a tree-burning power station in the UK, has signed a deal with three Japanese shipping companies to develop a “bioship” fuelled by wood chips instead of marine diesel. It hopes to see the first wood-fuelled cargo ship set sail by 2029.

The vessel would itself be used to ferry woodchips* harvested by Drax from North American forests *to new markets in Japan…

However, the plan will infuriate many environmental groups who argue that cutting down forests for fuel is the wrong way to reach net zero.

Wood chips is only one form of biomass. It should be possible to pelletize weeds or corn stover for use as green fuel–recycling carbon dioxide.

Ideally you look at yield–i.e., sun energy fuel produced per acre. Ideally on land not suited to farming. The right crop is likely to be regional given rainfall, soil types, temperature range, growing season etc.

At the same time, there is a lot more to a tree than to a grass, a much higher energy density.

“Tree crops are the most grown. representing 70% of the global biomass market due to the high plant to heat (BTU) conversion rate. Simply stated, biomass tree crops require far less plant mass compared to grass and vegetable to achieve a consistent burn rate.”
