BeFC raises €3M of VC seed funding.

Published on
June 30, 2020

Bioenzymatic Fuel Cells (BeFC) raises €3M to develop a paper-based sustainable energy source using enzymes.

Emerging from several years of academic research, BeFC is the inventor of bioenzymatic fuel cells based on papers and enzymes. The biofuel cells developed by BeFC naturally fit within the renewable energy sector and demonstrate a low environmental impact. This exciting startup has showcased its ambition to become a global key player in sustainable development by moving towards the industrialised production of its portfolio of bioenzymatic fuel cells. Thanks to its business model and its disruptive technology, BeFC has convinced Demeter, BNP Paribas Développement and Supernova Invest to invest in the technology’s development.

“We are excited to have raised this round of seed funding with investors that share our vision of a sustainable energy source. The entire team at BeFC are looking forward to bringing this innovative technology to the public, via our partners and our forward-thinking clients.“ Dr. Jules HAMMOND, CEO.

Bioenzymatic fuel cells: a thin, flexible, miniature energy source

This enthusiasm has also allowed the startup to win many international awards, including the first prize of the MIT GSW - GEM challenge (Global Startup Workshop of Massachusetts Institute of Technology – Grenoble École de Management) and the inaugural Nature ResearchSpinoff prize « One to Watch », awarded in 2020.

“We were immediately impressed by the range of possible applications for the enzymatic paper bio-batteries developed by BeFC. This disruptive innovation brings real environmental benefits in markets as diverse as IoT, smart-packaging or disposable electronic devices, replacing button (or coin) cell batteries. As such, the BeFC team has, in a very short time, formed great industrial partnerships with major players from the targeted sectors to deploy its bio-batteries in different applications. We are therefore delighted to support BeFC with its smart-city/smart-energy seed-fund in this very promising growth phase of the company.” explains Olivier BORDELANNE, Partner at Demeter.

An innovative alternative to miniature batteries:

BeFC has invented miniature ecological biofuel cells that are paper-based, ultra-thin and flexible. The technology uses biocatalysts to convert natural substrates like glucose and oxygen into electricity. The fuel cells can be activated with any fluid, such as environmental or biological fluids. In addition, BeFC fuel cells do not contain chemicals that are hazardous or polutant to the environment, and they do not disrupt existing recycling processes.

“We were impressed by the level of rupture that these glucose biofuel cells bring to the fuel cell industry. The technology is already mature and meets the growing energy needs of many markets such as disposable medical devices and connected logistics. With its composition in paper, enzymes and glucose, this bio-battery does not use toxic products and does not disrupt the recycling process. This innovation perfectly matches the deeptech target of our Supernova 2 seed fund. “ stated Marine GLON, Investment Director at Supernova Invest.

Potential applications:

BeFC technology is suited to low-power applications; where sensor data is collected and processed quasi-continuously, and then intermittently transmitted via wireless protocols. BeFC products can power many electronic devices, from microprocessors to low-energy wireless communications (LoRa, Bluetooth, WiFi, etc.). Therefore, BeFC products offer a strong platform for the development of technology in emerging markets, such as disposable medical devices or connected logistics. Indeed, electronics integration in disposable and wearable devices have become increasingly important. The button or coin cell power sources typically used today are difficult to recycle, toxic or dangerous to the environment. The development of safe and ecological devices is often a barrier to the progression of single-use and single-patient devices. BeFC believes this approach will not only allow the replacement of batteries for existing applications, but also open new opportunities for low-power ultra-thin health monitoring, logistics / transportation monitoring, and Internet of Things (IoT) applications.

Bioenzymatic fuel cells sustainable energy source low power electronics. From laboratory testing to industrial-scale production: BeFC is the result of the collaboration of a team of multidisciplinary experts. This seed investment will allow the development of the production line in  Grenoble region, helping the company to fulfill its client manufacturing requirements. BeFC’s ever-growing team is simultaneously focused on R&D and the acquisition of joint development contracts with major industrial customers.
