Second-Tier Energy Winners: Why dynaCERT, 2G Energy, and SFC Energy Are Poised for Strong Growth

dynaCERT: New Hydrogen Speculation

The great hydrogen euphoria on the stock markets has faded for now. Many former high-flyers have long since given back a large portion of their price gains. Yet in such phases, new and interesting entry opportunities often arise, fueled by hopes of a turnaround. This includes the shares of dynaCERT. The Canadian company has developed HydraGEN, a retrofit technology for diesel engines that uses electrolysis to convert distilled water into on-demand hydrogen and oxygen. These gases are injected into the air intake to reduce fuel consumption and lower emissions. The major advantage is that this allows dynaCERT to target a massive existing market rather than rely on replacing entire vehicle fleets. Millions of trucks, construction machines, generators, and mining vehicles are still in use worldwide and will continue to operate for many years to come. Especially in these times of high diesel prices, dynaCERT's technology is becoming increasingly attractive. For freight forwarders or operators of large fleets, every litre of fuel saved directly improves profitability. A major growth opportunity for the North American company lies in the raw materials sector. Mining companies, in particular, are under increasing pressure to improve their carbon footprints. dynaCERT's specially developed HG4C and HG6C systems are designed for massive diesel engines with displacements of up to 90 litres, such as those used in mining vehicles or stationary generators. The company could offer a comparatively cost-effective bridging technology in this sector. Systems have already been delivered to large open-pit mines in South America.

The growth story becomes even more exciting thanks to the CO₂ credit strategy. After years of development work, the company has made significant progress in gaining recognition for its emissions reduction methodology. In the future, customers could not only save on fuel costs but also generate CO₂ credits. This creates a potential second revenue stream that could significantly increase the technology's appeal. With its proprietary telematics platform HydraLytica, dynaCERT also has a digital ecosystem that collects consumption and emissions data. If broad commercialization succeeds, this could result in a high-margin platform business with recurring revenue.

Operationally, there are clear signs that the company could be entering a new growth phase. Management recently refined its strategic priorities for 2026 and is increasingly focusing on markets with a high probability of success. At the same time, production has been ramped up. This was driven by repeat orders from the energy and raw materials sectors, as well as growing interest from the mining industry.

Also of interest is the international expansion. Most recently, dynaCERT reported progress in entering the market in Vietnam. There, strategic partnerships have been established and pilot projects launched. The company is thus seeking to increasingly position its technology outside North America. At the same time, dynaCERT is strengthening its presence in Europe and targeting sectors such as logistics, port operations, construction, and heavy transport. Europe, in particular, is continuously tightening emissions standards for commercial vehicles. Solutions that can be deployed immediately without infrastructure investments costing billions are likely to become more attractive as a result.

Exciting Turnaround Story

Of course, the stock remains speculative. The major commercial breakthrough has yet to come. dynaCERT must now prove that the technology can be rolled out on a large scale and that the CO₂ certificate strategy will indeed become a significant driver of revenue and earnings. Acceptance among fleet operators and industrial companies also remains a decisive factor. This is precisely why the current situation could be of interest to risk-tolerant investors. While many market participants have long written off hydrogen stocks, dynaCERT is working behind the scenes on a potentially highly scalable combination of emissions reduction, fuel savings, and CO₂ monetization. Should the company provide operational proof that this model can be implemented on a large scale, the currently modest valuation could quickly appear in a different light. However, the stock has the potential for one of the most exciting turnaround stories in the hydrogen and cleantech sector.

2G Energy: Beneficiary of the AI Boom

What can happen when a stock takes off was demonstrated in recent months by 2G Energy. The share traded more or less sideways for several years within a range of EUR 20 to 40 before breaking out to the upside in the spring. Since then, the German small-cap has gained a solid 75% to over EUR 70. For a long time, 2G Energy was regarded as a specialist in biogas plants. In the meantime, the investment story has grown significantly. The company is benefiting from several structural trends simultaneously: energy transition, decentralization, security of supply, and, looking ahead, hydrogen as well. Many of the plants are already H₂-ready and thus prepared for future hydrogen applications. This fuels investor imagination. Growth prospects surrounding artificial intelligence were also a key driver of the stock price. For the new data-driven world to function at all, it needs electricity—a great deal of it. The global expansion of data centers is creating a veritable hunger for energy. This is exactly what 2G Energy benefits from. The Westphalian company is among the leading providers of combined heat and power plants and decentralized energy solutions. The plants generate electricity and heat directly where they are needed. This increases security of supply and reduces grid dependencies.

The largest single order in the company's history recently attracted attention. 2G Energy received a multi-million-euro order for a data center project in the US. At the same time, discussions are underway regarding additional projects in the low three-digit megawatt range. This opens up a completely new market for the Münster-based company. Data centers often cannot wait for the lengthy expansion of public power grids and are seeking their own energy supply solutions. This is where 2 G's systems come into play. The prospects in North America are particularly interesting. Management recently reported pre-orders totalling several hundred megawatts. Industry observers expect this to lead to further major contracts in the coming quarters. Should this trend materialize, the current forecast is likely to appear rather conservative.

With revenues of up to EUR 490 million in the current year and up to EUR 620 million in 2027, 2G is now growing into new dimensions. The stock is no longer a hidden gem, but it could still be poised for a revaluation amid momentum in the data center market. However, following the recent price surge, short-term pullbacks could also be on the horizon. Prices below EUR 60 would then be a good entry point for interested investors.

SFC Energy: Beneficiary of the Defence Boom

While dynaCERT aims to improve the efficiency of existing diesel engines and 2G Energy strengthens decentralized power supply, SFC Energy ensures that critical systems can operate independently of the power grid. The Bavarian company develops fuel cell solutions based on methanol and hydrogen. The systems are used wherever a secure, mobile, and grid-independent energy supply is required. This includes industrial facilities, government agencies, security organizations, and, increasingly, military applications.

However, the real catalyst for the share price came just a few weeks ago. SFC Energy won the largest order in the company's history. As part of a support initiative funded by the German government, the company is supplying fuel cell systems worth EUR 42.7 million to Ukraine. The order will contribute to revenue and earnings as early as this year. Management subsequently raised its 2026 forecast significantly. Revenue is now expected to range between EUR 163 million and EUR 175 million. Earnings before interest, taxes, depreciation, and amortization (EBITDA) are now projected to be between EUR 29 million and EUR 34 million. This means SFC is growing significantly faster and more profitably than previously anticipated. Even more important, however, is the strategic significance of the order. Defence and public safety are increasingly becoming a key growth market. According to management estimates, the share of these sectors in consolidated revenue could rise to around 30% in the medium term. This makes SFC Energy a beneficiary of rising global defence budgets.

Unlike many traditional hydrogen companies, SFC is already generating solid profits today. The company is growing profitably, has a solid balance sheet, and occupies attractive niche markets. This makes the stock a comparatively conservative way to benefit from the hydrogen and defence trends.

Not every exciting stock market story takes place among the big corporations. It is often worth looking at the second tier. That is exactly where investors can currently find three companies—dynaCERT, 2G Energy, and SFC Energy—that are benefiting in very different ways from more efficient energy use and thus from one of the most important megatrends of our time. dynaCERT is focusing on more efficient internal combustion engines, 2G Energy on decentralized power supply, and SFC Energy on off-grid fuel cell systems. Rising energy demand, the desire for security of supply, and decarbonization all play into the hands of these three companies. While the shares of 2G Energy and SFC Energy have already gained significantly recently, dynaCERT is still poised for an upward breakout. The stock is therefore the most speculative turnaround bet in this trio, holding the greatest upside potential.
