In 2024, hydrogen emerged as a climate-friendly alternative to fuel as well as electricity. Promising projects sparked to life on both the production and consumption fronts. Despite Trump’s pro-oil stance, analysts are optimistic about hydrogen’s future in this new year- 2025.
According to BNEF, clean H2 supply is projected to increase 30X and could reach 16.4 million metric tons annually by 2030. This surge is mostly attributed to supportive policies and a flourishing project pipeline.
As we step into 2025, several crucial moments await the low-carbon, clean hydrogen sector. This year, a wave of innovative startups is pushing the boundaries of hydrogen production, storage, and application, capable of transforming the clean energy landscape.
Here are the top 4 hydrogen startups of 2025 that are leading this revolution:
1. Hydrogenious LOHC Technologies (Germany): Revolutionizing Hydrogen Transport
Germany-based Hydrogenious LOHC Technologies is addressing one of the toughest challenges in the hydrogen value chain—safe and efficient storage and transport.
Founded in 2013, the company’s Liquid Organic Hydrogen Carrier (LOHC) system uses benzyl toluene, a reusable heat transfer oil, to chemically bind hydrogen. This approach enables hydrogen to be stored and transported just like traditional fuels using existing infrastructure—cutting down both cost and risk.
Hydrogen System Targets 40% Emissions Cut
Hydrogenious, Bosch, and partners are installing a hydrogen power system at Hermann Josef Hospital in Erkelenz, Germany. Funded by Germany’s Education and Research Ministry, the Multi-SOFC (Solid Oxide Fuel Cells) project combines LOHC and SOFC technologies to deliver clean heat and power.
The project aims to reduce HJK’s carbon emissions by up to 40%. Initially, Bosch’s SOFC units run on natural gas while still achieving up to 60% electrical efficiency. Even in this early phase, the system cuts emissions by roughly 150 metric tons annually.
By 2026, Hydrogenious will integrate its LOHC technology, enabling the system to run primarily on hydrogen. Waste heat from the SOFC will power a dehydrogenation unit that releases hydrogen from the LOHC on-site, boosting overall system efficiency and lowering the hospital’s carbon footprint even further.
Thus, the Multi-SOFC project aims to deliver a reliable, low-emission energy solution. It shows how hydrogen can cleanly and affordably power large facilities. Once complete, it will serve as a global model for decarbonizing critical infrastructure.
Why The Company Stands Out?
- Backed by Big Names: Secured investments from JERA Americas, Temasek, Chevron, and Royal Vopak.
- Industrial Projects: Operating a large-scale hydrogenation facility at Chempark Dormagen and contributing to the ‘Green Hydrogen @ Blue Danube’ initiative.
- Global Expansion: Through a joint venture with Vopak, Hydrogenious is laying the groundwork for a global hydrogen supply chain.
- Commercial Success: Deployed the first full LOHC-based hydrogen mobility chain, including pilot refueling stations in Germany.
With additional funding of €17 million raised in early 2025, the company is now accelerating its next phase of project deployment. Hydrogenious LOHC isn’t just innovating—it’s commercializing at scale.

2. HiiROC (U.K.): Clean Hydrogen without CO₂
UK-based HiiROC is tackling the cost and emissions problem of hydrogen head-on with its Thermal Plasma Electrolysis (TPE) technology. Instead of relying on electricity-heavy electrolysis or carbon-intensive steam methane reforming, HiiROC produces zero-emission hydrogen by breaking down hydrocarbons into hydrogen and solid carbon black, a useful by-product.
What Makes It Game-Changing?
- Ultra-Efficient: Uses 80% less power than water electrolysis.
- Emission-Free: Produces no CO₂—a major leap in clean hydrogen production.
- Modular Design: Can scale from small on-site generators to industrial-sized plants.
- By-Product Value: Generates carbon black, widely used in tyres, plastics, and inks, offering dual revenue streams.
Zero-emission Carbon Black
HiiROC’s clean tech not only produces hydrogen but also generates solid, zero-emission carbon black as a by-product. It replaces traditional oil furnace methods that emit heavy pollution by creating a stable, pure form of carbon black with no emissions.
Thus, it offers a cleaner alternative for industries that rely on carbon black, including tyres, rubbers, plastics, inks, and toners.
Unlocking New Potential Uses
HiiROC is also exploring innovative ways to put this clean carbon to work. Potential future applications include:
- Environmental filters
- Soil enhancers
- Animal feed additives
- High-performance and construction materials
In short, what was once a polluting material now has the potential to support decarbonization across multiple sectors.
Moving on, the company has raised over $35 million from major investors like Centrica and Kia Motors, reflecting strong market confidence. It’s partnering with Associated British Ports to build a production facility at Saltend Chemicals Park, set to produce 10 tonnes of hydrogen per day.
The company’s recognition under the UK’s Low Carbon Hydrogen Standard further boosts its regulatory credibility. With scalable tech, strategic projects, and government support, HiiROC is targeting to decarbonize hard-to-abate sectors while keeping costs low.
3. Electric Hydrogen (U.S.): Scaling Clean Hydrogen for Heavy Industry
Founded in 2020, Electric Hydrogen, headquartered in Massachusetts, is on a mission to make green hydrogen cost-effective at an industrial scale. It focuses on building next-gen electrolyzer systems to decarbonize hard-to-electrify sectors such as:
- Steel and metals production
- Chemicals and ammonia
- Cement manufacturing
- Sustainable aviation fuels (SAF) and e-methanol
In 2023, Electric Hydrogen raised $380 million in a funding round led by heavyweights including BP, Microsoft, and United Airlines. The raise pushed the company’s valuation past $1 billion, making it the first electrolyzer startup to reach unicorn status.
What Makes It Unique?
Electric Hydrogen’s standout innovation is its HYPRPlant—a fully integrated, modular electrolyzer platform designed for speed, scale, and cost savings.
- Built around high-output PEM stacks
- Pre-engineered for rapid site assembly
- Cuts total installed costs by up to 60%
- Backed by a 1.2 GW/year gigafactory in Massachusetts
This approach simplifies deployment, reduces risk, and accelerates timelines compared to traditional electrolysis systems.
Powering Cleaner Industries
Their 100MW plant uses advanced PEM technology and a smart “plant-as-a-product” design. This setup lowers costs by using fewer materials, saving space, and reducing installation time.
Their special electrolyzers produce much more hydrogen from the same stack size, making it easier to scale up and support big industrial projects.
Achieved Net Zero Emissions in 2023
In 2023, Electric Hydrogen’s Scope 1 and 2 emissions totaled around 600 metric tons of CO₂-equivalent, while Scope 3 emissions from their supply chain reached 17,725 metric tons.
However, the company offset all Scope 1 emissions by purchasing certified carbon credits from Sterling Planet and covered Scope 2 emissions with renewable energy certificates (RECs) from Terrapass.
- This resulted in net-zero Scope 1 and 2 emissions in 2023.
Most of their energy use came from electricity for manufacturing and R&D, along with natural gas for heating. A small amount of diesel was used to run a generator at the 1 MW protoplant in San Carlos, CA. It plans to use electricity to power larger test facilities in San Jose, CA, and Devens, MA.
4. Hystar (Norway): High-Efficiency Answer to Green Hydrogen Scaling
Founded in 2020 and based just outside Oslo, Hystar is a rising star in the clean hydrogen space. The company is reengineering how electrolyzers work—leveraging proprietary proton exchange membrane (PEM) technology to make green hydrogen production both cheaper and more scalable.
What Sets It Apart?
What sets Hystar apart is its ultra-thin membrane design—90% thinner than standard PEM systems. This breakthrough allows its systems to run at much higher current densities, which means:
- Lower energy consumption
- More hydrogen output per unit of power
- Reduced use of critical raw materials
The result is a serious step-change in how economically green hydrogen can be produced at an industrial scale.
Smart Design, Scalable Tech
Hystar’s electrolysers are fully containerized and modular, making them easy to deploy. Its flagship Vega 1000 system delivers 5 MW of clean hydrogen production, designed for sectors like:
- Heavy industry
- Clean transport
- Renewable energy storage
- Industrial decarbonization
Better yet, the technology is built with automation and mass manufacturing in mind, future-proofing it for global scale.
Sustainable Production: From Megawatts to Gigawatts
Currently operating at 100 MW annual capacity, Hystar is scaling rapidly. Through Project Sagitta, the company is launching a gigawatt-scale, automated production facility in Høvik.
- Starting with 1.5 GW/year by 2027
- Expanding to 4.5 GW/year by 2031
- Expected to produce 6 million tonnes of green hydrogen over 10 years
- Avoiding over 11 million tonnes of CO₂ emissions
This bold scale-up reflects Hystar’s long-term vision: to help shift the market away from fossil-based “grey” hydrogen toward truly sustainable, zero-emission fuel.
The company secured $36 million in funding, drawing interest from strategic investors committed to decarbonization. Most notably, it has partnered with Nippon Steel Trading to accelerate the adoption of its tech across global markets.
With cutting-edge PEM innovation, a scalable business model, and the infrastructure to back it, Hystar is building more than electrolyzers—it’s building the backbone of the future hydrogen economy.

The post Top 4 Hydrogen Startups of 2025 Powering the Net Zero Future appeared first on Carbon Credits.
Most businesses that decide to act on their net-zero targets reach the same point of friction. Buying carbon credits has meant tracking down brokers, sitting through sales calls, and requesting a quote just to learn a price, sometimes with limited proof of what you are buying.
The earnings calls that quietly reframed climate from sustainability question to operating risk.
Three earnings calls in the last 18 months tell the story without any help from a press release.
Hershey, May 2024: cocoa price exposure compresses margin, and the company attributes part of the cost shock to West African weather. Olam, July 2024: coffee climate exposure quantified in the annual report. JBS, January 2025: supply chain climate disclosures expanded materially in response to investor pressure and regulatory expectation. None of these companies issued the announcement as climate news. They issued it as financial news. The climate-linked supply chain risk did not arrive with a sustainability framing; it arrived as a P&L line.
You are probably reading this article because you suspect the same thing is happening to your business. This piece walks through what is showing up on which earnings calls, how procurement and finance leaders are quantifying the exposure, and what serious corporates are doing about it before the regulator asks.
Where climate risk has already appeared in earnings
The pattern is consistent across resource-intensive sectors. A weather event compresses supply, the price spikes, the cost flows through the income statement, and the analyst on the call asks whether the event is anomalous or structural. Increasingly, the honest answer is the second one.
Cocoa is the cleanest example. The 2023 to 2024 West African harvest fell sharply on the back of erratic rainfall and disease. Cocoa futures more than tripled. Companies with concentrated West African sourcing absorbed the cost; companies with diversified sourcing absorbed less. The exposure was not climate as ESG topic. It was climate as cost of goods.
Coffee follows the same pattern. Brazilian and Vietnamese harvests have moved on weather more sharply across the last several seasons. Roasters with long-tenor supplier relationships and origin diversification have managed the volatility; roasters with spot-market exposure have not. Wheat, sugar, palm oil, beef: the same dynamic in different commodities, a pattern the IPCC AR6 Working Group II report projects will intensify across agricultural systems through mid-century.
What this means: climate risk is no longer a footnote in the 10-K. It is a line item the CFO has to explain on the call.
The three commodity exposures that hit margin first
For most companies with material Scope 3 exposure, three exposures dominate the near-term P&L risk.
- Concentrated single-origin sourcing in a climate-vulnerable region. If your tier-one supply for any material commodity sits in one geography, you have a concentration risk that climate amplifies. Diversification across origins is the obvious hedge, but it takes years to build and requires relationships you cannot acquire by tender.
- Supplier financial fragility under climate stress. Smallholder farmers, who supply a large share of the global cocoa, coffee, and palm oil market, do not carry the balance sheets to absorb yield shocks. When yields collapse, they exit. When they exit, your supply base shrinks, and the surviving suppliers raise prices. The risk is structural, not cyclical.
- Logistics and storage exposure to extreme weather. Hurricane disruptions to Gulf shipping, drought-driven Panama Canal restrictions, flooding in European inland waterways: each of these has moved input costs in the last three years, a pattern documented in Munich Re’s natural catastrophe data. The exposure shows up as a one-quarter event in the financial press but accumulates over time on the cost line.
TCFD and ISSB disclosure changes
The disclosure architecture has now caught up with the risk. The Task Force on Climate-related Financial Disclosures, whose recommendations are now embedded in the ISSB’s IFRS S2 climate standard, requires companies to disclose climate-related risks across physical and transition categories, with quantification where possible.
For physical risk specifically (the climate-linked supply chain risk you are reading about), the disclosure must address both acute exposures (extreme weather events) and chronic exposures (gradual changes in temperature, precipitation, and growing seasons). The disclosure must address the time horizon over which the risk is material, the parts of the value chain exposed, and the financial impact under different scenarios.
The CSRD imposes similar requirements under European law, with double materiality (both financial and impact materiality) embedded in the assessment. The practical effect: your auditors and your investor relations team now need a defensible answer to the climate-linked supply chain risk question, and the answer needs to be quantified.
What procurement and finance can do now
Three actions matter near-term.
Map your exposure. Most companies do not have a clear view of which tier-one and tier-two suppliers sit in which climate-vulnerable geographies. Without the map, you cannot quantify the risk, and without the quantification, you cannot disclose it credibly. The map is the foundation, and World Resources Institute climate risk research provides useful public tooling to start.
Diversify and deepen, in that order. Diversification across origins reduces concentration risk, but the deeper move is to invest in the resilience of the suppliers you already have. Regenerative practices, agroforestry, soil health interventions: these reduce yield volatility under climate stress and protect your input cost trajectory.
Embed the climate spend inside procurement, not outside it. Treating climate risk as a sustainability cost line subordinates it to the ESG budget. Treating it as a procurement and resilience investment puts it in the budget that matters, which is the cost-of-goods budget that the CFO defends quarterly.
Nature-based supply chain investments are the asset class designed for exactly this purpose. They sit inside the value chain, they reduce climate-linked supply risk, they generate verifiable Scope 3 reductions, and they produce the documentation an auditor and a regulator can both test.
If you are quantifying climate-linked supply chain risk in advance of the next earnings cycle or the next disclosure period, the carbon and sustainability experts at Carbon Credit Capital can help you map your exposure and structure a Dual-Value Model response that addresses reduction, resilience, and disclosure-readiness in a single program. Schedule a consultation.
More and more small and medium-sized businesses are hearing the same question from their larger customers: What is your carbon footprint? That question now travels down entire supply chains, and it arrives next to tender requirements, certification criteria, and rising customer expectations.
