Green transition and geopolitics are putting pressure on the energy system – but a Danish solution can both stabilise the electricity grid and create new business opportunities.
The green transition has long been driven by our ambition to reduce CO2 emissions. At the same time, however, global geopolitical conflicts have placed increasing focus on energy independence and national security of supply.
So while the intentions are good, the reality is that energy supply is currently being challenged by a range of factors. We cannot always rely on solar and wind forecasts, meaning production can fluctuate and be difficult to predict. This places significant demands on the electricity grid, says Jens Seehusen Christensen, CEO of Danish company Inopower.
If you do not balance the electricity grid, you risk blackouts, says Jens Seehusen Christensen, CEO of Inopower.
It is precisely at this intersection between stable, green energy and security of supply that the company’s boilers can support the market.
When surplus electricity becomes a resource
Inopower develops high-voltage electrode boilers, also known as electric boilers, which can absorb surplus electricity and convert it into heat. When the wind blows more strongly than expected or the sun shines more intensely, the boilers can be connected to relieve pressure on the electricity grid.
You only switch them on when there is too much electricity in the grid. That is why they are a strong asset in the energy supply system, explains Jens Seehusen Christensen.
The technology has become increasingly relevant in a market where electricity prices fluctuate significantly. In 2025, the electricity price was lower than the gas price for more than 20 per cent of the year’s hours, and there were more than 500 hours with negative electricity prices.
In practical terms, this means that companies can not only use the electricity – they can also earn money by being flexible.
We have actually sold boilers to companies that end up earning more from their electric boiler than from their core business, he says.
With payback periods of less than one year, the investment has become attractive to both industry and energy companies.
From Danish niche to global potential
Today, Inopower has a solid foothold in Denmark and Germany, but demand is growing internationally. Projects in countries including South Korea and Chile point to a rapidly developing market.
I actually believe we are sitting on an uncut diamond, says Jens Seehusen Christensen, CEO of Inopower.
This development is being driven by several factors: increasing volumes of renewable energy, greater price fluctuations and a growing need for energy security. At the same time, industry is moving from reliance on a single energy source towards so-called multifuel strategies, where electricity plays an increasingly important role.
But there are also challenges. An undersized electricity grid in Europe means that green energy is currently being wasted because it cannot be transported or used efficiently.
Nevertheless, the direction is clear: the pan-European strategy is about creating a more electrified and flexible energy system.
And in this development, Danish technology that both balances the electricity grid and creates sustainable business opportunities may prove to be more valuable than most people have yet realised.
