Swiss professor: “We still haven’t come up with the perfect energy storage solution.”

They’ve had coal, gas and oil filling that requirement for many decades. But now they scratch their heads and look for viable alternatives, with nothing of note to show for their effort. Climate obsessions like the ‘net zero’ illusion can do strange things to people’s ability to think rationally. Throwing away something vital without a suitable replacement is asking for trouble.

If the transition to renewables is to succeed, we will need a viable means of storing surplus heat and electricity, says TechXplore.

Globe spoke to experts from ETH Zurich about the promising technologies that could help us reach net zero.

Switzerland aims to transition to a net-zero energy system by 2050. To meet this goal, it will need to replace fossil fuels with renewables.

The Swiss government has also taken the decision to phase out nuclear power. As a result, its plans for carbon neutrality will require not only the electrification of transport and heating by means of electric vehicles and heat pumps, but also measures to compensate for the loss of nuclear generating capacity.

To meet increased energy demand, Switzerland will primarily rely on hydro and photovoltaic energy sources and, to a lesser extent, wind power.

But what about the times when the sun doesn’t shine and the wind doesn’t blow? “The grid has to constantly smooth out fluctuations in renewable generation and match supply to demand,” says Gabriela Hug, a professor at the Power Systems Laboratory at ETH Zurich. Hug also heads up the ETH Energy Science Center (ESC), which recently released modeling showing that a renewable energy system is both technically feasible and economically viable.

“Obviously, it won’t be simple,” Hug acknowledges. “And without effective energy storage, the transition to renewables won’t even be possible.”

Energy storage systems stabilize the grid, providing the necessary capacity to offset the volatility of generation from renewable sources such as solar, wind and hydro. This requires technologies that are able to efficiently convert electricity and heat into a form that can be stored and then released back into the grid when needed—whether on a seasonal or minute-by-minute basis.

If Switzerland starts investing more in photovoltaics, it will end up generating more power than it needs at noon on a summer’s day. To make that midday solar power available both day and night, it needs short-term storage solutions. “But Switzerland’s biggest challenge is actually long-term storage,” says Hug.

The country already produces too little electricity in the winter and relies on imports to cover increased demand—and this seasonal imbalance will only intensify as the transition to renewables gathers pace.

“Photovoltaic plants in particular generate surplus electricity in the summer,” says Gianfranco Guidati, an expert in energy system modeling at the ESC. “But in winter the sun is weaker and heat pumps are keeping people’s homes warm—that’s when we see a gap between energy supply and demand.”

The key question for Switzerland is how to store this excess solar power from the summer to the winter. With demand for storage systems clearly growing, Hug argues that the safest approach is to invest both in established and emerging technologies: “We still haven’t come up with the perfect energy storage solution.”

  1. If we came up with the perfect energy storage solution, the WEF and the Greens would reject it because it would not be useful to scare and control and tax people.

    Actually, the perfect energy storage solutions were done for us millions and/or billions of years ago.

    One perfect class of energy storage is various named Fossil Fuels, Coal, Oil, Natural Gas, etc.

    Another perfect energy storage class is different named Nuclear Energies, Fission, Fusion, Nuclear Decay, Transmutation, etc.

    The WEF and the Greens did reject all of these because they are abundant and reliable and people have gotten over much of their fear of them.

  2. As the “so called scientists”, I call them “consensus people”, scratch their heads and think of frightening ways to store energy to help those they have succeeded in brainwashing, “some others” need to look at the non western countries we must compete with and maybe even defend ourselves from, China, India, Russia, and many others who are going to continue to use more and more more perfect Fossil and Nuclear Fuels and figure out how “green countries” can hope to not be controlled by those who will have unlimited energy powering their economies and militarizes.

  3. What kind of perfect energy storage can we protect from nature, earthquakes, tornadoes, solar storms, lightning, etc.?

    What kinds of perfect energy storage can we protect from our domestic and foreign enemies?

    What kinds of weapons, what can power weapons that can defend us against our domestic and foreign enemies, who will use fossil fuels and nuclear energy against us, in the weapons and in the delivery systems for these weapons used against us?

  4. Russia and Ukraine are not using “green weapons” in their current conflict. If one of them had used “green weapons” that war would have been over in a few days.

  6. The “greens” have not discussed the emissions from wars, they have not discussed how “green” countries defend themselves, considering that their windmills and solar panels and batteries depend on potential enemies. They cannot be “green” countries and mine and process materials and manufacture much of anything needed for defense or waging war.

    Surplus? People will be dying from scarcity.

    US military: “I don’t know how we’re going to do battlefield charging yet. Nobody knows that”.

    Got fireproof batteries yet?

    Net zero…perfect storage solution…’nobody knows’…cloud cuckoo land 🙄

  9. Brian R Catt says:

    Physics and engineering know the energy density and intermittency of renewables simply mean there is not enough to gather to store, if they even could. And that makes it a lot more expensive, although they have a lot more places tofollood for pumped storage lower lakes, but that’s where people live and the roads and railways are….. It is simply nuts. What are the qualifications of the people planning this, Physics and engineering? Anyone care to explain where they are going to get the 60TWh of electrical energy from? Will do the David MacKay watts per square metre assessment maths later, I know its bonkers before I start.

    we have moved from comically stupid to dangerously psychotic. Yet, the masses of sheeple keep voting for these hucksters and grifters and the power mad types.

    What’s wrong with a big pile of anthracite?

  12. Phoenix44 says:

    If renewables have a capacity of below 50%, you are just buggered. That means you need huge overcapacity to charge huge storage. The economics will always be horrible.

  13. Gamecock says:

    ‘Storage’ is a head fake. They speak of ‘storage’ as a cure for intermittency, which it obviously isn’t. ‘Storage’ is a tool to get people to give up their power supply and accept renewables, when those pushing it KNOW IT WILL FAIL.

    A crime against humanity.

    Prepare the gallows.

  14. JB says:

    “***Experts*** discuss future surplus power storage technologies”

    Building hi-tech monuments to stupidity.

    “We still haven’t come up with the perfect energy storage solution.”

    It must be up there in cloud cuckoo land somewhere. Keep looking 🙄
