Bitmain rolled out its next-generation Antminer S21 and S21 Hydro ASIC miners on the World Digital Mining Summit (WDMS) in Hong Kong on Sept. 22, revealing the essential efficiency stats your complete business has been ready for. The S21 has a hash fee of 200 terahashes per second (TH/s) and an effectivity of 17.5 joules per terahash (J/T), whereas the S21 hydro hashes at 335 TH/s and 16 J/T, which is notable on condition that till lately, most Bitcoin ASICS had been working above the 20 J/T degree.
With electrical energy prices persevering with to rise year-over-year and the Bitcoin halving projected to happen in April 2024, ASIC effectivity is shortly turning into the paramount focus of miners, and plenty of are additionally pivoting towards folding in renewable vitality sources as a core element of their operations.
Bitcoin miners deal with effectivity and renewable vitality
Sustainable development in the mining industry was a core theme mentioned in a majority of the panels on the WDMS. Within the opening roundtable, staff members from Terrawulf, Core Scientific, CleanSpark and Iris Vitality shared their views on how additional integration of renewable vitality sources will turn into a essential technique to implement for a lot of miners after the April 2024 Bitcoin provide halving.
In accordance with Nazar Khan, Terrawulf’s chief working officer:
“There’s a big transition happening within the provide facet of the technology course of; there’s a concerted effort to decarbonize your complete provide stack, and so after we discuss Bitcoin miners consuming extra renewable vitality, that’s a part of a broader theme that’s occurring throughout the USA with out Bitcoin mining as nicely. The position that we play is finding our Bitcoin mining hundreds in locations the place that’s occurring and the way can we facilitate that decarbonization course of.“
One affect of the upcoming provide halving is that miners will preserve the identical capital and operational prices, plus the necessity to pay down any revolving money owed, whereas primarily seeing their block reward distribution reduce in half.
Because of this, miners will both want to extend the proportion of their hash fee derived from sustainable vitality sources or make effectivity changes to their ASIC fleet to take care of or improve their profitability.
Relating to the rollout of the Antminer S21 and its potential affect on the mining business, BMC founder Justin Kramer stated:
“The S21, if dependable, pretty priced and available — and sure, that’s a number of ifs with Bitmain’s historical past — might revolutionize the crypto mining panorama with its effectivity. It’s mainly packing the ability of two S19 100T miners into one unit. Regardless of this, the burgeoning aftermarket firmware market, coupled with hydro/immersion programs, give miners extra instruments to maintain older technology miners, such because the S19, worthwhile additionally. Thus, whereas the S21 represents a notable development, it could not render sub 110 TH/s miners fully out of date.”
When requested about what else caught this eye from the S21 launch, Kramer famous that:
“I like that Bitmain is rewarding environmentally pleasant mining farms with higher pricing and superior supply with their new Carbon Impartial Certificates. However, I’ll add that, it was a bit of shocking after I observed that each new S21 fashions supply 33% extra hash fee (S21 200T versus 151T on S19j XP; S21 hydro is 335T versus the S19 XP Hydro at 257T). Is that this a coincidence? I’m uncertain, and it seemingly alerts extra of the identical systematic mannequin releases from Bitmain the place a slight tweak to the firmware and possibly just a few different objects which might be adjusted leads to a average improve in hash fee and a brand-new miner.”
Bitcoin is en path to turning into an ESG asset
A theme of the previous few years has been a rise in Bitcoin miners and BTC advocates pushing again towards the assertion that Bitcoin mining is dangerous for the atmosphere, and that the business’s reliance on carbon-based vitality manufacturing accelerates emissions.
Countering this angle, Hong Kong Sustaintech Basis professor in accounting and finance, Haitian Lu, bluntly introduced that:
“Bitcoin mining is selling renewable vitality adoption in lots of areas.”
Lu defined that “through the years, Bitcoin mining has turn into extra environment friendly and can be utilizing cleaner vitality. Historical past tells us that human growth from an agricultural society to industrialization to the way forward for a digitalized financial system goes with each rising vitality consumption per capita. What makes the distinction is human’s capacity to make use of renewable vitality will increase, thus attaining sustainable growth.”
Just like the views shared by different panelists, Lu stated that Bitcoin miners’ participation in demand response agreements with energy producers and distributors results in vitality grid effectivity, and so they “present an financial incentive for the event of renewable vitality “promotion and growth of renewable vitality initiatives.”
Along with Bitcoin mining tapping into stranded vitality, encouraging the event of renewable vitality initiatives and serving to to steadiness electrical grids, the effectivity developments of next-generation ASICs just like the Antminer S21 scale back miners’ vitality consumption whereas additionally permitting them to spice up their earnings.
