Ulf Bossel a une réflexion d'une pertinence et d'une lucidité vraiment époustouflantes. Docteur de l'Université de Berkeley en Californie et Président de l' European Fuel Cell Forum depuis 1994, il est à l'origine du concept d'Electron Economy.
Ulf Bossel:
“An electron economy can offer the shortest, most efficient and most economical way of transporting the sustainable ‘green’ energy to the consumer
(...) Electricity could provide power for cars, comfortable temperature in buildings, heat, light, communication, etc.
In a sustainable energy future, electricity will become the prime energy carrier. We now have to focus our research on electricity storage, electric cars and the
modernization of the existing electricity infrastructure.”

Interview:
Ben : Okay, so let us start talking about the sustainable energy path for us then. I know early in the discussion you were talking about the electron economy and I know
that you have written papers talking about how today about 80% of our energy is derived from chemical energy and 20% from physical sources and the future will be pretty much exactly the opposite,
so can you explain that a bit? What is chemical energy?
Ulf Bossel: Yes. What people need is physical energy. We need motion of vehicles, we need light, we need heat, and we need communication. These are all physical energy. People need
chemical energy only for eating and drinking. Okay, that is what the people's needs are. Now, to satisfy these needs, engineers of the 18th, 19th or 20th century have developed a fantastic
technology for the conversion of chemical energy of fossil origin into physical energy needed by people: steam engines, gas turbines, internal combustion engines and so on. All these inventions
are fantastic. It is a fantastic technology, but in the future this technology will run out of fuel because there is not enough of oil, gas and coal left to drive our economy. Also, we may have
political issues restricting access to fossil resources. The use of fossil fuels may further be restricted to stop global warming. Anyway, the renewable energy from wind, solar and so on is
mainly harvested as electricity. Therefore, as fossil resources become depleted, the chemical energy base vanishes. Electricity from wind, water, waves, solar and ground heat will become
the new energy base. Once electricity has become our source energy, we should not make the mistake to convert it into chemical energy like hydrogen in order to continue with energy
technologies which were developed to convert natural gas or fossil fuels to electricity or motion, but we should find the courage to say, "Goodbye steam
engines. Goodbye Carnot cycles. Here we are with electricity. We don't need you any longer."
