...simultaneously fostering a highly competitive environment within the EU to drive innovation and reduce costs. Energy efficiency and renewable energy will be key to ensuring a more competitive Europe.

In these sectors, globalization has often been limited or inconsistently implemented worldwide—likely due to concerns about security of supply, geopolitics, and an "oil state" mentality.
The challenge in Europe now is to navigate the coming months of uncertainty while ...

Protectionism, tariffs, technical barriers have always existed. Many outside EU will likely view the Carbon Border Adjustment Mechanism (C-BAM) as another such measure.
The conference focused on utilities within heating, water, and energy more broadly.

• A stronger focus on supply security with flexible power plants (~5 GW) to cover 10–20% of production
The real solution lies in using proven tech + smart policy measures to phase out fossil fuels+ ensuring a secure, balanced energy supply

• Enhanced energy savings in buildings
• Expanded district heating systems and large-scale/mega heat pumps + individual heat pumps
• Increased electrification of industry and electric vehicles
• Sufficient renewable capacity to match these demands (around 5-7 GW solar PV and 11-12 GW wind power)

Key takeaways:
• The original target was always meant to be met on market terms—not at any cost.
• Policy initiatives continue: removing barriers, increasing neighbor compensation, and fast-tracking EU measures.
In my opinion, achieving the 2030 targets relies on:

E.g. the 3 GW offshore tender recently would have increased the capacity in West Denmark by about 60% in one go. Clearly that is overreaching the immediate need. There is a need to have smaller tenders and to plan for longer 2045 onshore renewables - which likely still not will be a quadrupling. 👇

Actually - even if it grew as expected, the quadroubling was still far too much. Some energy developers and municipalities express frustration - but it's better to plan locally for goals on renewables which is needed. Remember - we already have ~65% renewable electricity in the mix. 👇

Toyota’s shift to hydrogen trucks/buses could make sense in niche markets. Even here electricity dominate. Battery technology improves faster than hydrogen adoption. What City would buy a hydrogen bus and not an EV bus? What construction company wouldnt simply buy electric machinery?

In Denmark they also disappear.
❌ Better Alternatives Exist – EVs w cheap batteries dominate the market. With falling costs and rapid expansion of charging networks, they’re outpacing hydrogen every turn.

Hydrogen FCVs remain far far less efficient than battery-electric vehicles (BEVs). You cannot innovate the laws of physics away!
❌ Lack of infrastructure. Hydrogen refueling stations are rare + costly. Even Shell shut down hydrogen stations in California, leading to lawsuits from Mirai owners

While Toyota is pivoting to hydrogen trucks and buses, its bet on hydrogen for passenger vehicles has been a costly mistake. Here's why:
❌ Expensive & inefficient – A Toyota Crown hydrogen model costs $6,500 more than a hybrid due to high production costs.

For deep decarbonization, negative emissions will be necessary—not as a first solution.
The focus should remain on rapid deployment of renewables, but we can’t ignore the long-term need for carbon removal. Whether we have the right techniques yet is questionable—costs remain extremely high.

🔹 Aviation contrails create warming beyond CO₂ emissions.
🔹 Agriculture produces methane and nitrous oxide emissions that can’t simply be "electrified." Agriculture, forestry, and land use changes account for up to 20% of global emissions.

The logic? Instead of removing CO₂ from smokestacks, just shut down the power plants altogether. This is hard to argue against.
🚀 But is it really this simple? This holds for a large share of emissions—likely 60-70%—but some emissions are much harder to eliminate:

Mega heat pumps—like those from MAN Energy Solutions—enable flexible electricity consumption, especially when combined with large-scale heat storage.
But to truly decarbonize, we need diverse energy sources to avoid reliance on expensive or fossil-based electricity. 🚀

This isn’t just about one city. Across Europe, district heating networks are evolving, with pioneers like Wien Energie, Aalborg Forsyning, and DIN Forsyning (Esbjerg/Varde) leading the way.

It isn’t just a record. It’s a sign of things to come. With grid flexibility—better interconnection, storage, and market reforms—we can fully embrace the solar revolution. Let’s not fear curtailment! Higher curtailment levels are simply part of a system where cheap, abundant solar dominates.

With global competition intensifying, particularly from China’s rapid advancements, this turbine signals a strong European response. 🇪🇺🏆
If successful, it could set new efficiency and capacity benchmarks, further driving down offshore wind costs. ♻️🔋

The SG DD-276 turbine, which has been shrouded in secrecy, now stands with its tower, nacelle, and rotor hub in place. 🏗️
This marks a major milestone for Siemens Gamesa as they push to stay ahead in offshore wind innovation.

Instead of focusing on what isn’t working, we should recognize the strong momentum behind Denmark’s green transformation.
In the coming half year it will be important with 1) more district heating role out, 2) more small and large heat pumps, 3) more waste heat recovery and geothermal successes,

We do have 65% wind power & PV in the mix. And many projects are ready to jump on board with higher electricification.
✅ Despite setbacks, the heat sector is steadily phasing out fossil fuels. EV adoption is surpassing expectations.
Yes, challenges exist, but not everything is failing-far from it

I do not think necessarily it is a crisis, more a "reality check". We can move faster on certain issues. But the technology push needs to be realistic. Remember that:
✅ Political targets on renewable electricity were initially too high, and now they are being adjusted to align with market conditions

Today's piece brings together insights by Lena Kitzing, @brianvad.bsky.social and myself on how to improve the design of the offshore wind auctions.
I argued that Denmark should de-risk wind by auctioning 2-way Contracts for Differences, based on my recent & ongoing work. www.dr.dk/nyheder/vide...

By adjusting state guarantees, the government hopes to improve the business model for both hydrogen and offshore wind, ensuring they can develop in parallel. These changes could unlock new opportunities and reinforce Denmark’s role in the European energy transition.

After setbacks, including failed offshore wind tenders and delays in hydrogen infrastructure, the government aims to make investments in green energy more attractive. A central focus will be DKs planned pipeline to Germany, which is expected to begin with a shorter route from Esbjerg to reduce costs
