AM Drilldown: Canadian Carbon Credits Could Fuel 3D Printing and More


Share this Article

Canadian Finance Minister Chrystia Freeland unveiled the country’s latest budget, which offers $16.4 billion in tax credits for clean tech manufacturing, clean electricity and hydrogen over the next five years, alongside $500 million in support  carbon capture and storage (CCS). Canada is in the process of using its new national budget to introduce a system to lock in future carbon prices. This, in turn, will be used as a means of increasing investment into low-carbon technologies, which could include additive manufacturing (AM).

Canada’s Carbon Credit Contracts for Difference

Contracts for difference” set a future price on tradable carbon credits, awarded to heavy emitters for cutting their pollution output. The Canadian government will make up the difference if the market price for these credits fall below the contract minimum. A growth fund established in last year’s budget that will be up and running “in the coming months” will be used to drive large projects.

The country’s largest polluters, such as those in oil and gas, have claimed that the lack of any certainty related carbon credit pricing has limited their willingness to invest in emission reduction projects, such as carbon capture and hydrogen, that could earn them these points. Moreover, if a credit pricing system were to be dismantled in the future, such projects would be financially wasteful from their perspectives.

Existing rules see polluters pay per tonne of carbon emitted above a sector-specific level. They can also create credits through emissions reduction and sell the credits. However, such a carbon credit market is seen as unstable due to the fact that cheap credits could flood the markets as large-scale projects begin operating. Through contracts for difference, the Canadian government can guarantee pricing stability, incentivizing more businesses from participating in the carbon credit market.

“They’ve got some discretion to tailor those contracts based on whatever is needed to get these projects over the hurdle,” said Dale Beugin with the Canadian Climate Institute. “So that works pretty well for first-of-a-kind, unique projects that are new and will have big benefits for Canada because they’re innovative.”

The plan is meant to target large-scale decarbonization projects, but the scheme is being discussed as a means of potentially targeting smaller programs as well.

Carbon Credit Projects

When most people think about emission reduction technologies, the first thoughts that come to mind are wind and solar. However, these forms of renewable energy have their own limitations, particularly for industrial operations that require large amounts of energy storage. Others may consider less developed climate solutions, such as carbon capture and storage (CCS) or hydrogen power, both of which still require substantial technological or infrastructure advances.

Before further-out technological solutions to the climate crises can be rolled out at scale, nearer-term tools, such as 3D printing and other forms of advanced production, now represent the best low-hanging fruit in the world of energy efficiency. For this reason, at least a portion of these investments will surely be directed into AM.

AM is especially relevant to the oil and gas industry, to which the global economy is still intricately dependent. Those players, who wish to manage the energy transition as much as possible in order to ensure their survival, are aiming to first improve the efficiency of their own operations before they are willing and/or able to fully commit to renewables. For this reason, they will turn more and more to AM to optimize fossil fuel use in order to make every last drop of fuel last that much longer. Of all the world’s oil and gas sectors, Canada may be one of the best-positioned to secure its existence with AM.

Then, as other technologies move in to replace fossil fuel infrastructure, their developers will also rely on AM in order to increase the energy efficiency of their own technologies. This means that AM will also become the go-to manufacturing process wherever and whenever it fits for wind, solar, and nuclear. For less-developed replacements, like CCS and hydrogen, 3D printing will obviously be key for the early design and testing phases before it is utilized for reasons of energy efficiency.

Global Trend

What’s crucial to note about this development from Canada is that it is being in part attributed to moves already being made by the United States. Specifically, the Inflation Reduction Act (IRA) will lead to over $1 trillion in investment into such areas as renewable energy. This, along with related bills like Bipartisan Infrastructure and CHIPS Acts, will also fuel an AM boom for the same reasons stated above. Metal 3D printing startup Seurat and materials firm 6K both believe that to be the case, while GE is already priming IRA funds to be directed toward 3D printing.

As national governments seek to keep pace with the U.S., we will continue to see moves like those made by Canada. In addition to the contracts for differences, Canada aims to implement a 30% investment tax credit to boost clean-tech manufacturing, especially in the electric vehicle supply chain. We can rightly assume that these funds will also make their way into AM and other advanced manufacturing technologies. In fact, we’ve already seen Canada’s Project Arrow apply AM to vehicle production. This should just be a foreshadowing of what’s to come.
