World : Energy Web Foundation: Blockchain essential for EV growth, community solar

Distributed energy solutions such as solar PV, batteries, and smart controls are getting cheaper by the day and will soon outperform traditional energy sources such as coal, gas, and nuclear power, says Hervé Touati. In any case, Blockchain-type solutions will be needed for the mass deployment of electric vehicles, he warns.

Hervé Touati was recently appointed CEO of the Energy Web Foundation (EWF), an energy Blockchain non-profit based in Zug, Switzerland, with a hub in Berlin.

Touati joined the EWF from Shell, where he led the company’s Connected Energy business, focused on distributed energy resources. Touati also held senior roles at cleantech think tank Rocky Mountain Institute, E.ON Connected Energies, E.ON Climate & Renewables, and McKinsey & Co. He holds a PhD in computer science from the University of California, Berkeley.

He spoke to EURACTIV’s energy and environment editor, Frédéric Simon.


  • Blockchain can make green power certificates cheap, fast and tamper-proof, allowing peer-to-peer energy transactions.
  • Cost of tracing solar PV production can be reduced by a factor of 5 to 10.
  • Blockchain will force digital identities on electronic equipment, making cyber-attacks less likely.
  • As electric cars become mainstream, Blockchain can optimise battery charging and ease pressure on power grids.
  • Technology is operational, more work needed to scale it up.
  • On the regulatory side, it is essential that the EU opens the distributed energy market.
