Canaan's Case for Bitcoin Mining as a Flexible Load
At Mining Disrupt Miami 2022, Canaan's Edward Lu argued that miners earn their place by soaking up surplus wind and solar, and launched the AvalonMiner 1266.
Imagine a power plant that doesn't just consume electricity, but actively stabilizes the entire grid by soaking up surplus wind and solar energy before it is wasted. This is the vision Edward Lu, President of Canaan Creative, brought to the stage at Mining Disrupt Miami 2022, held from July 26 to 28, 2022. This session was recorded 1538 days ago, a time when Bitcoin traded at $21,268, compared to its current price of 97,300 dollars. Lu’s argument has aged remarkably well, as the industry’s push for grid flexibility has only intensified in the years since.
Lu argued that the long-term survival of the industry hinges on its ability to integrate with renewable energy sectors. He stated that the sustainability of the bitcoin mine industry is closely related to our future humanity. This is not just a moral stance, but a technical one. As the world shifts toward intermittent power sources like wind and solar, the grid needs loads that can scale up and down quickly. Lu posited that Bitcoin mining has also become a flexible load which encourages and promotes the use of sustainable energy. By acting as a demand-side resource, miners can help prevent curtailment, where excess renewable energy is simply lost because it cannot be stored or transmitted.
To demonstrate this capability, Lu highlighted the latest advancements in hardware efficiency. Canaan Creative has developed machines that achieve a hashrate over 100 terahash per second and has energy efficiency ratio below 35 gel. This level of efficiency is critical because it allows miners to remain profitable even when electricity prices fluctuate. When renewable energy is abundant, it is cheap, and efficient miners can turn on. When energy is scarce, they can throttle back or shut down, providing the grid with a predictable, dispatchable load.
Lu also addressed the environmental constraints that have historically limited mining locations. He noted that immersion oil cooling bitcoin mining can break free of environment limitations. Traditional air-cooled facilities struggle in hot or humid climates, but immersion cooling offers a robust solution that can operate in a wider variety of geographic locations. This flexibility allows mining operations to co-locate with renewable energy projects, regardless of local weather patterns. Furthermore, Lu emphasized that bitcoin mining can turn this exceed capacity into a storable value. By converting surplus renewable energy into Bitcoin, miners effectively create a digital storage medium for energy, solving one of the biggest challenges in the clean energy transition.
Looking ahead, Lu predicted that moving forward the wind and solar energy will make will mark up a large proportion of green energy. In this landscape, Bitcoin miners are not just consumers of power, but essential partners in the energy transition. The industry has moved beyond the initial debate of whether mining is sustainable to a practical discussion of how it can make the grid more resilient.
