The international inhabitants is rising quickly. It is estimated that by 2050, we’ll cowl practically 10 billion folks. The development of the inhabitants additionally signifies that the demand for energy is rising to present energy for our homes, companies, transportation, and so forth.

As a society, certainly one of the greatest challenges we face is how to meet this demand whereas lowering international carbon dioxide emissions.2 pcs emission.

answer? It is no surprise that we want to quickly increase the use of renewable energy. What is commonly unclear are the obstacles we nonetheless want to overcome. Some of the greatest challenges we face are:


While we’re accelerating the assortment of renewable energy by large-scale wind farms and photo voltaic farms, certainly one of the long-term modifications we want to concentrate to is the institution of infrastructure to truly use this energy.One of the most well-known examples is the growth of charging factors for electrical vehicles, however let’s Don’t overlook energy transmission and distribution strains, energy storage and administration services.

sustainable improvement

In order to actually cut back emissions, we want to examine all elements of the energy system, from how energy is produced to how energy is used and distributed. Just like the Shift sub-brand we launched, Electric automobiles are extra appropriate for the total surroundings, however solely Electric cars are charged with green electricity No emissions in any respect.


Many renewable energy options are nonetheless way more costly. E.g, The cost of green hydrogen is about $3-$6/kg, And the value of hydrogen manufacturing from fossil fuels is between 1 and 1.8 US {dollars} per kilogram.To incentivize customers and companies to make modifications, the authorities has been utilizing The type of subsidies and carbon taxes. But what we actually want is a brand new answer so that everybody could make the transition clearly and simply.

Per 12 months, New energy challenge We are searching for start-ups and scale-up corporations with cutting-edge concepts that may assist corporations cut back greenhouse fuel emissions in an reasonably priced and sustainable means. This 12 months, they’re searching for options that match the following themes: new journey, energy storage, energy administration and hydrogen energy.

If you’re a start-up or massive enterprise in Europe or Israel, and have a superb answer, Register before June 1, 2021.

We caught up with final 12 months’s winners and scaled up H2Pro And begin Finno ExergyTo perceive how their know-how will help speed up the transition to inexperienced hydrogen, and the way successful the New Energy Challenge will help them additional develop options.

Are we transferring in the direction of a “green hydrogen economy”?

For a very long time, inexperienced hydrogen has been hailed as the “fuel of the future”, an alternate energy that may utterly change our energy system. In order to grow to be the future chief of inexperienced hydrogen manufacturing, authorities businesses from Chile to Australia to the European Commission have introduced formidable new energy methods centered on inexperienced hydrogen in the previous few years.

In truth, so as to grow to be a world chief in the hydrogen transition, the EU is working onerous to make Euro Global Standard Conduct worldwide hydrogen commerce.

In truth, on paper, hydrogen meets all necessities. Unlike fossil fuels, it occurs to be the most considerable ingredient in the universe. Like fossil fuels, it may possibly be burned to produce energy or transformed into electrical energy, however when it’s produced utilizing renewable energy, it doesn’t produce greenhouse fuel emissions.

It has been utilized in petroleum refining and fertilizer manufacturing, however it has a variety of potential functions. Imagine having the ability to fly on a inexperienced hydrogen-powered flight throughout the world with out worrying about rising your carbon footprint. From powering massive factories to heating our homes, inexperienced hydrogen may be firmly rooted in our future energy system.

This is nothing new. Since the Nineteen Seventies, the concept of ​​establishing a “hydrogen economy” has been round.

So why can we not make full use of this multifunctional ingredient?

The difficulty is:

  • Production could be very costly.Bank of America estimates that present prices can have to Down 85% So that it may possibly compete with hydrogen derived from fossil fuels.
  • Depending on the quantity of inexperienced energy out there, it may possibly simply change. No wind or sunshine? There isn’t any energy to serve you.
  • The explosive mixing potential of working with hydrogen and oxygen poses a significant security hazard.
  • Finally, new infrastructure will want to be established to distribute inexperienced hydrogen on a bigger scale.

Does this imply that the design of the “green hydrogen economy” is only a pipe dream?

Make inexperienced hydrogen manufacturing reasonably priced and secure

Hydrogen is the most considerable ingredient on earth, however it may possibly solely be present in compound type, comparable to H2 pcsAnswer: This signifies that it needs to be extracted and used individually from different particles.

Just like electrical vehicles, the diploma of carbon neutrality of hydrogen is the similar as the kind of energy utilized in its manufacturing course of and gas.

Although hydrogen is broadly used in the present day, most of it’s produced from coal or pure fuel.This so-called “gray hydrogen” emits carbon monoxide2 pcs Emissions at the time of manufacture. On the different hand, inexperienced hydrogen produced by various energy sources comparable to wind and photo voltaic energy is carbon impartial.

However, as talked about earlier, certainly one of the greatest obstacles to the transition to inexperienced hydrogen is the enormous manufacturing prices concerned.A report by the International Renewable Energy Agency discovered that inexperienced hydrogen is Two to three times more expensive Instead of utilizing fossil fuels and blue hydrogen from carbon seize and storage.To recap, the value of hydrogen manufacturing from fossil fuels is between $1-$1.8/kg, and The cost of green hydrogen is about $3-$6/kg.

Before inexperienced hydrogen and grey hydrogen are cost-competitive, it can be troublesome to increase their makes use of on a broader foundation.

But scale up H2Pro We have proposed a technique to develop a brand new course of, which cannot solely assist cut back the value of hydrogen manufacturing, but in addition make hydrogen manufacturing extra environment friendly and safer.

Green hydrogen is normally produced by a course of referred to as electrolysis, which makes use of electrical energy to separate water into hydrogen and oxygen.

H2Pro’s E-TAC (Electrochemistry, Thermal Activated Chemistry) additionally performs this operation, the distinction is that it makes use of two totally different steps: an electrochemical (E) step and a thermally activated chemistry (TAC) step to separate hydrogen And oxygen.

By separating the two, they will remove the want for the costliest a part of an electrolysis-based system: the membrane. Use firepower to produce oxygen In this course of, effectivity also can be improved to be certain that no energy is misplaced throughout the manufacturing course of (not like the electrolysis course of, the place up to 25% of the energy is misplaced throughout the electrolysis course of).

Finally, the incontrovertible fact that oxygen and hydrogen are produced in two totally different steps (relatively than at the similar time) reduces the danger of blending the two components and makes them safer.

Their purpose is to increase the use of hydrogen by lowering the value to $1 per kilogram.

Solve the gas hole

Even if we resolve the drawback of manufacturing affordability, inexperienced hydrogen nonetheless is determined by the availability of renewable energy.

One factor it’s best to find out about hydrogen is that it’s not an energy supply, however an energy provider. Green hydrogen can be used to transport and retailer energy produced by various fossil fuels comparable to wind and photo voltaic energy. This signifies that on sure sunny days, the energy produced by the photo voltaic panels can be saved and used later. It also can be transported and traded abroad.

Despite the vital development in the use of renewable energy, we nonetheless don’t have sufficient infrastructure to meet present energy needs. As the inhabitants grows, the demand for energy will solely enhance. Therefore, we want to discover new options to extra effectively use our energy and stability the provide.

This is the place Finno Exergy, Is the winner of the New Energy Challenge (New Energy Challenge) entrepreneurial competitors.

For many years, engineers have been rising the temperature of the fuel turbine by enhancing the effectivity of the fuel turbine or by creating new supplies, for instance, rising the temperature inside the fuel turbine. However, the progress caused by the combustion course of, particularly the strain acquire combustion (PGC), is sort of untouched.

Example of how PGC works in a gas turbine

Finno Exergy developed the first answer that may generate the strain acquire required to considerably enhance the effectivity of fuel generators. With its know-how, the turbine can cut back gas by 20%.

Comparison of traditional gas turbine and PGC-based gas turbine

Although this may assist us use inexperienced hydrogen extra successfully, Another side of its answer will assist the transition to extra widespread use of renewable energy, that’s, when the former is in brief provide, both inexperienced hydrogen or a combination of hydrogen and pure fuel can be used.

Tero Ijäs, product improvement supervisor at Finno Exergy, defined:

The quantity of hydrogen will change throughout the transition interval and in the coming many years. This means you want a very versatile system that may use inexperienced hydrogen when it’s out there and easily substitute the system in order that pure fuel or some artificial gas can be used when not in use. Therefore, on this sense, we will see that this innovation will play a giant function in the transition section and past.

Finno Exergy’s first product will be a small micro-turbine unit that may generate electrical energy and medium-pressure steam. However, as Ijäs shared, the better impression and the cause why he believes they’ve gained the new energy problem is that their programs can be tailored to massive fuel generators, comparable to massive energy vegetation, ships and offshore fuel generators. Gas turbine. aviation trade.

For us, this can be a nice studying, as a result of we’re extra technical workers, relatively than skilled folks in enterprise. During the intense three-week problem, we obtained quite a lot of good recommendation and coaching. They actually challenged our enterprise mannequin and considered it, and helped us create the cornerstone of success. We are actually a part of the GameChanger program, which supplies us extra credibility and proves that our answer actually works.

And Ijäs has each cause to consider that their merchandise will be in a position to attain this new degree.

It has been wanting shiny for the previous six months. Many massive corporations have launched their hydrogen energy technique. The EU has signed a inexperienced settlement, however as a result of hydrogen is a highly regarded matter at the second, there are extra upcoming financing alternatives.

As Ijäs stated, though these progressive applied sciences will help us get nearer to the new period of inexperienced hydrogen, it nonetheless takes time and funding to obtain this purpose.

Small improvements can be made, however if you would like to have an even bigger impression, then you definitely actually want a bigger infrastructure to actually understand it.

Although inexperienced hydrogen will assist us cut back carbon dioxide2 pcs In the long term, carbon dioxide emissions have elevated considerably, which isn’t a panacea for fixing the local weather drawback. It would require a patchwork of latest applied sciences and breakthroughs in wind energy, geothermal energy, biomass energy and different fields so as to rework our energy system in time to obtain emission discount targets.

Are you prepared for options that have an effect on the improvement of renewable energy?This New energy challenge It will come again once more in October 2021 and is now open to start-ups and large-scale enterprises from Europe and Israel. Register before June 1, 2021.
