Growing economies want one useful resource above all else: electrical energy. Over current a long time the enlargement and growth {of electrical} infrastructure i.e., energy grids, has resulted within the elevated use and emissions of Sulphur Hexafluoride (SF6), the world’s strongest greenhouse fuel.
That is due to SF6’s frequent use in switchgear, grid-scale switches which can be key {hardware} elements discovered all through {the electrical} infrastructure. Nonetheless, quickly this might be a factor of the previous.
Electrical energy performs an important function in each growing economies and enhancing residing requirements. We’ve seen this to a terrific extent in China and India, notably lately.
Proper now, greater than half of world power consumption takes place within the Asia-Pacific area, the place round 85 per cent comes from fossil fuels. Nonetheless, 10 per cent of the inhabitants throughout the area nonetheless lacks entry to electrical energy, and plenty of extra depend on conventional biomass strategies, comparable to wooden combustion, for heating and cooking.
To handle these issues, in addition to these posed by speedy urbanisation and industrialisation, power demand is rising. Due to this, I consider appreciable alternatives exist to keep away from the long-term lock-in of power applied sciences and infrastructure which exacerbate the issue of local weather change.
It’s vitally vital that rising electrical energy demand is met by renewable and low-emission power sources. Nonetheless, we must always not overlook different elements such because the infrastructure used to move that power: transmission and distribution grids are two examples.
For power transition to be actually profitable, we have to be certain that the entire power system is ‘inexperienced’ and never solely deal with power era itself.
Enterprise not as ordinary
Younger local weather know-how firms have an important function to play as it’s more and more clear from a local weather perspective that the ‘enterprise as ordinary’ mannequin is not viable. We’d like contemporary pondering to develop progressive applied sciences that may assist us attain an power system freed from dangerous greenhouse gases.

The power sector is notoriously conservative. From my expertise, established gamers are typically sceptical of recent concepts and applied sciences. That is the place local weather tech firms can show that sustainable innovation isn’t solely vital from a sustainability perspective however also can have a optimistic impact on an organization’s backside line.
When my daughter Matilda was born in 2015, I developed a a lot clearer life perspective. I wished to see a future for her the place the power we use day-after-day doesn’t destroy our planet. This performed an vital function once I determined to affix my Co-Founders in beginning Nuventura 5 years in the past.
My first in-depth encounter with sustainable power era was once I studied nuclear engineering on the technical universities in Aachen, Germany, and Gothenburg, Sweden. Surprisingly, fission, fusion and renewable energies had been all bundled below ’various’ power era, whilst just lately because the early 2000s!
I realised that I didn’t consider fission to be a viable ‘bridging know-how’ for the power transition; renewable energies might be the one answer. I spent the following 5 years as a guide, advising firms about capital effectivity within the renewable power sector. I additionally consulted on power effectivity optimisation within the heavy industries sector.
In 2014, I began my first firm. It was not energy-related, but it surely wasn’t lengthy earlier than I missed working in that house. In 2017, I made a decision at hand over operations to a brand new administration group, and joined my Co-Founders Manjunath Ramesh and Nikolaus Thomale, after they confirmed me how a lot affect we might have, notably in serving to to cut back the power sector’s use of SF6 by growing switchgear applied sciences which substitute the extraordinarily potent greenhouse fuel with dry air, basically regular breathable air, with none moisture.
What’s SF6?
Greenhouse gases are synonymous with any dialog surrounding the power sector and local weather change. Regardless of it not being very well-known, Sulphur Hexafluoride (SF6) is the world’s strongest, with a world warming potential (GWP) of 25,200.
Which means one kg of SF6 is equal to 25,200 kg of CO2. The European Union banned SF6 for many functions in 2014, however this didn’t lengthen to the power sector attributable to a scarcity of other choices on the time.
Greater than 80 per cent of all SF6 produced is used within the power trade as an insulating medium for gas-insulated switchgear (GIS). Switchgear is a key element discovered inside all electrical infrastructure. They operate like a grid-scale mild swap – they flip completely different sections of the grid on and off.
SF6’s emissions are at present at an all-time excessive, with world annual emissions (shut to eight,000 tons) equating to the yearly CO2 emissions produced by round 100 million vehicles. To make issues worse, in a business-as-usual state of affairs, using SF6 is predicted to develop by greater than 75 per cent by 2030.
Moreover, although recycling of used SF6 is frequent, it’s usually not destroyed due to the issue and price related to this destruction. Subsequently, it could fairly be anticipated that every one SF6 that at present exist and that will probably be produced sooner or later will persist for 1000’s of years, whether or not in gas-insulated switchgear tools or, in the end, in our ambiance.
As a consequence of SF6’s environmental affect, regulators such because the European Fee and California Air Useful resource Board (CARB) are anticipated to section out its use within the power sector by 2031. The Chinese language authorities has additionally begun an analysis of SF6’s function within the power sector. It’s for these causes that sustainable options are urgently wanted.

Nuventura gives such another. We’ve developed the world’s first medium voltage (as much as 36 kV) GIS which replaces SF6 with dry air. We’ve executed this whereas sustaining the qualities which make SF6-GIS enticing all over the world, compact bodily dimensions, excessive reliability, and low upkeep necessities.
Innovation problem
Local weather change is arguably the largest innovation problem humanity has confronted. We’ve restricted time to vastly scale back greenhouse fuel emissions and attain internet zero by 2050. ESG (Environmental, Social, and Governance) industries and local weather tech will probably be very important within the growth of present and future applied sciences to make this transformation potential.
For instance, Indonesia plans to fabricate 600,000 electrical automobiles and a couple of.45 million electrical bikes by the 12 months 2030, in accordance with the ASEAN power outlook for 2022. In keeping with the identical report, Southeast Asia’s power necessities are anticipated to rise by 60 per cent by the 12 months 2040. So, it’s no shock that firms on this house are attracting rising curiosity from traders.
As nations all over the world proceed to expertise the unfavorable results of local weather change, that is solely more likely to speed up. The newest Intergovernmental Panel on Local weather Change (IPCC) report printed earlier this 12 months, repeated requires drastic motion. This was echoed in Glasgow’s COP26.
It cites a plan for nations and companies to work intently collectively to speed up the adoption of inexpensive local weather know-how all over the world.
This elevated deal with ESG in personal markets is main firms and traders to adapt their methods, together with rising rules such because the European Union’s ‘Match for 55’ plan, which targets decreasing greenhouse fuel emissions by 55 per cent by 2030.
Many firms have additionally made public commitments to net-zero and have set science-based targets. Furthermore, multibillion-dollar mega-funds are more and more being channelled into local weather tech.
Nonetheless, one alarming side we’ve skilled inside the enterprise capital house, that must be highlighted, is that VCs stay trapped in fund constructions and life cycles related to Tech (Software program) firms.
Local weather and deep tech, particularly {hardware}, can’t be assessed by the identical KPIs (Key Efficiency Indicators) as software program firms and consumer-oriented firms comparable to e-commerce.
VCs should be capable to make investments considering longer-term horizons. They need to not demonise CAPEX (Capital Expenditure) as they do at present and should settle for that software program alone won’t save our planet. Many VCs are very vocal about this and repeatedly spotlight it, however solely a fraction of them act accordingly.
I plan to dedicate the remainder of my skilled life to combating local weather change. A part of my motivation is that I simply love engineering! With the ability to invent new applied sciences that remedy actual bodily issues is a real privilege.
I additionally see local weather change as the only greatest downside for many species (people included) on our planet. So, if what I like to do can assist to unravel the numerous challenges posed by local weather change, why not do it?
