Headquartered in France, Nexedi is an innovative Enterprise solution provider focused on delivering open source software and hardware to solve complex business applications issues (such as ERP, CRM and cloud operation) in a very short time and with maximum flexibility. Customers include Airbus, Kyorin, Woelfel, PSA, Teralab and SANEF amongst many others.

Jean-Paul Smets, CEO Nexedi, stated, “We have been strong advocates of OCP for several years now and we are delighted to begin working with a new member of the community. Hydro66 are a perfect partner for us as they reflect our core values of delivering environmentally friendly solutions at a fraction of the “Big 5” market price. Further, our customers see a lot of value in a cloud solution deployed in the EU with an EU partner. Delivering our Rapid.Space racks pre-built by ITRenew to Hydro66 and having them available to our customers in a matter of minutes is exactly the benefit we expected from an OCP colocation facility.”

The cloud Infrastructure-as-a-Service (IaaS) market is accelerating at 27% year on year and poised to drive the US$45.6 billion market toward US$150.7 billion by 2023, according to independent research published by Frost & Sullivan.

Ali Fenn, Chief Innovation Officer at ITRenew, explains "With progress happening in the shift to renewables, as much as 75% of the CO2e impact of data center compute equipment is tied to the manufacturing of servers, rather than their usage. Circular economy through recertification more than doubles the life of OCP hardware used by very large companies, and can reduce net CO2e of data center equipment by 25% while also delivering significant TCO gains."

Patrick Smidts, Commercial Director of Benelux for Hydro66 commented,”With a world record PUE of 1.07 and power entirely provided by hydroelectric facilities, Hydro66 cuts by more than 99% the average CO2 footprint of cloud. Overall, by colocating Rapid.Space at Hydro66, Rapid.Space slashes CO2 emissions by up to 87% with a public price 5 to 10 times lower than competition."

Life Cycle Assessment

Based on Environmental Impact Using Lifecycle Assessment by Beth Whitehead, the ratio of CO2 emissions due to operation of the data centre can be four times higher than embodied emissions in the case of coal based energy (Case 1) or half of energy emissions in countries such as Sweden with a high shared of renewable energies (Case 2).

CO2 emission savings due to recertification range from 8% to 25% depending on the case. They are a consequence of an industrial process which doubles the lifetime of servers.

CO2 emission savings due to renewable energies from 55% to 87% depending on the case.

Rapid.Space Life Cycle Assessment
  Case 1 : Coal Case 2 : Sweden
Operational CO2 emissions 80% 33%
Embodied CO2 emissions 20% 67%
CO2 savings through recertification 8% 25%
CO2 savings through renewable and 1.07 PUE 79% 32%
Total CO2 savings 87% 55%

Hydro66 Assessment

The EU average CO2 per kWH of generation is 295.8g. Germany is 440g. Hydro66 is 0.04g. This is 7395x saving in CO2.

But now add PUE. EU Average is 1.7. Hydro66 is 1.07 therefore 90% difference. 7395 x 1.9 = 14050x saving in CO2 by hosting with Hydro66.

This means hosting a single 10 kW rack in Germany contributes over 66 tonnes of CO2 every year. This is the same emissions as flying in a passenger jet for over 300,000 km. Hosting with Hydro66 almost completely eliminates this source of CO2 from your carbon footprint

In terms of difference, this is the same as 66 flights Stockholm to Karachi (66,400 kg CO​2 ) / compared to a single 40 km taxi to the airport (4 kg CO​2).

  • Jean-Paul Smets is the founder and CEO of Nexedi. After graduating in mathematics and computer science at ENS (Paris), he started his career as a civil servant at the French Ministry of Economy. He then left government to start a small company called “Nexedi” where he developed his first Free Software, an Enterprise Resource Planning (ERP) designed to manage the production of swimsuits in the not-so-warm but friendly north of France. ERP5 was born. In parallel, he led with Hartmut Pilch (FFII) the successful campaign to protect software innovation against the dangers of software patents. The campaign eventually succeeeded by rallying more than 100.000 supporters and thousands of CEOs of European software companies (both open source and proprietary). The Proposed directive on the patentability of computer-implemented inventions was rejected on 6 July 2005 by the European Parliament by an overwhelming majority of 648 to 14 votes, showing how small companies can together in Europe defeat the powerful lobbying of large corporations. Since then, he has helped Nexedi to grow either organically or by investing in new ventures led by bright entrepreneurs.
