Bitcoin (BTC) mining infrastructure firm Northern Bitcoin AG has announced the completion of tests for its new air-cooled mining container, which houses 144 ASIC miners.

A press release published on Sept. 9 outlined that the highly mobile container solution has been designed as a piece of flexible and efficient infrastructure that will enable the firm to establish mining pools in countries with year-round cool locations.

Setting up shop anywhere energy is cheap, sustainable

Headquartered in Frankfurt am Main, Northern AG develops and operates Bitcoin-focused mining hardware that uses renewable energy sources and aims to attain optimal efficiency and sustainability.

The press release notes that Northern AG has developed and operated a mining pool with 21 water-cooled 41-foot containers — housing 210 ASIC miners each — in Norway for over a year.

The new water-cooled container has reportedly been developed with partners in Germany and will allow the firm to extend its operations, flexibly and at short notice, to new locations across Scandinavia.

Its 20-foot design — with a capacity to house 144 ASIC miners — has a significantly higher miner density than the earlier water-cooled containers. The firm says it is focused on deploying its mobile mining solutions in permanently cool locations where sustainable energy sources such as hydropower are cheap and abundant.

As the press release notes, efficient temperature control is critical for compute-intensive Bitcoin mining operations, during which the hardware required typically generates significant heat.

Bitcoin mining getting more energy-efficient

As recently reported, fresh data from aggregator Statista has indicated that Bitcoin (BTC) energy consumption is becoming rapidly more efficient, even as the global network’s hash rate continues to hit record highs.

Energy consumption as of July 2019 was 69.79 terawatt hours per year. In July 2018, the figure was 71.12 terawatts, while hash rate was almost 60% lower than at present.

A study in June found that three-quarters of Bitcoin mining activity is powered by renewable energy sources.

Mining hardware manufacturers such as Bitmain are similarly seeking to develop new solutions with greater processing capabilities and lower energy demands.
