In the race toward a sustainable future, hydrogen has emerged as a star player in the global clean energy transition. Among the companies embracing this transformative shift are NiSource Inc. and Sempra Energy, which are taking proactive steps to harness the potential of hydrogen as a key driver of a greener energy landscape.
NiSource just launched a multi-phase hydrogen blending project; it’s a pioneering project in the U.S. to use a blending skid in a controlled environment to combine natural gas and hydrogen at precise levels. The goal is to find out the best blend percentages and their benefits for consumers and the planet.
Taking the same direction, San Diego-based Sempra Energy, will also test electrolytic hydrogen blending into existing natural gas infrastructure. The energy giant is also working on what could be the nation’s largest green hydrogen energy infrastructure system.
NiSource Hydrogen and Natural Gas Blending
NiSource envisions the potential for substantial investments in hydrogen production, transportation, and storage. It comes following the conclusion of its current five-year $15 billion capital plan in 2027.
To make that vision a reality, NiSource is developing its capacity to handle hydrogen safely and efficiently. It also seeks to show to policymakers that low-carbon hydrogen can effectively decarbonize gas utility services.
Several hydrogen projects have been announced in the U.S., encompassing different areas of application.
NiSource pilot project, led by its subsidiary Columbia Gas of Pennsylvania Inc., will test a 20% hydrogen blend in natural gas distribution infrastructure. It facilitates the regulated blending of hydrogen into Safety Town’s natural gas system at varying concentrations.
The results of this project to be tested in Monaca, Pennsylvania will be key to demonstrate that hydrogen blending is feasible. The project is a collaboration between NiSource’s Columbia Gas and EN Engineering.
- Together, they’ll create a blending skid that will inject hydrogen into the gas stream at different percentages, from 2% – 20%.
The project will also assess the impact of various blending concentrations on different gas appliances through a model home. The goal is to ensure the proper functioning of equipment and to know if any adjustments on processes are necessary.
NiSource prioritizes safety and regulatory compliance in hydrogen blending. They will share data with the US Pipeline and Hazardous Materials Safety Administration for monitoring hydrogen-gas blends and their impact on pipeline materials.
Moreover, its other subsidiary, Northern Indiana Public Service Co. LLC (NIPSCO), plans to use a blend of gas and hydrogen to repower one of its turbines.
An Alternative to Electrification
In all these innovations, CEO Lloyd Yates emphasizes the importance of policies in incentivizing efforts driving the hydrogen transition.
He specified some federal tax credits and initiatives such as the Appalachian Regional Clean Hydrogen Hub (ARCH2). NiSource backed this application to secure a subsidy from the Energy Department’s funding program on setting up regional hydrogen hubs.
The Indiana-based utility aims to achieve net zero Scope 1 and 2 emissions by 2040. Hydrogen blending can further help the company tackle its elusive Scope 3 emissions, which are linked to customer’s gas use. Burning hydrogen as a fuel emits only water vapor, no greenhouse gasses given that it uses renewable sources.
NiSource said its hydrogen and natural gas blending strategy is part of their “Future of Energy” program. It particularly includes renewable energy and electrification strategies as well as renewable natural gas pathways.
Yates further noted that the project seeks to make hydrogen an alternative to electrification for customers facing financial challenges. It will allow them to reduce their carbon emissions without buying new appliances, thus making it a viable option.
Sempra’s Growing Sustainability & Hydrogen Innovation
Along with NiSource, other utilities like Sempra Energy are also exploring hydrogen projects to meet the nation’s clean energy goals.
With a strong focus on sustainability, Sempra pursues >20 hydrogen R&D projects to enhance grid resilience and promote decarbonization. It works with strategic research partners while providing funding worth $140 million in the last 2 years.
The funds are for research, development, and demonstration projects for cleaner fuels, hydrogen technology and infrastructure.
In particular, Sempra’s subsidiary Southern California Gas Co. (SoCalGas) partners with the University of California, Irvine on a demonstration project. They aim to show how electrolytic hydrogen can be safely mixed into the campus’ existing natural gas pipeline. Testing for this hydrogen-natural gas blending may start next year once approved.
The joint initiative aims to better understand how hydrogen could be delivered at scale through California’s existing natural gas system. It can either be for existing customers tapping at the grid or to produce clean electricity in zero-emissions fuel cells.
The testing project will use an electrolyzer to convert water into hydrogen for blending into the UCI campus gas grid. It will involve powering residential and light commercial equipment such as ovens, boilers, furnaces, and water heaters.
Initially, SoCalGas will use 5% hydrogen in the mix, aiming for up to 20%, the same as NiSource’s blending project. The ultimate goal is to also significantly reduce customer’s emissions from gas use.
The Missing Link in the Clean Energy Equation
SoCalGas announced its goal to reach net zero greenhouse gas emissions by 2045. That makes it the first large natural gas utility in the country to do so. Its parent company, Sempra, pledged to achieve net zero emissions 5 years later, by 2050.
The energy firm also proposed the Angeles Link, which could be the country’s largest green hydrogen energy infrastructure system. They refer to it as the missing link in the clean energy equation.
The initiative can potentially deliver cleaner energy to hard-to-electrify sectors such as heavy-duty transportation and industrial processes.
By replacing fossil fuel-powered trucks with hydrogen fuel cell trucks, Sempra Energy aims to eliminate up to 3 million gallons of diesel a day. This would result in displacing about 25,000 tons of carbon emissions each year.
First Hydrogen (TSXV: FHYD), a Vancouver and London-based company, specializes in zero-emission hydrogen fuel cell vehicles (FCEV) and green hydrogen production. Its innovation is a testament that FCEV works, with trial results beating test expectations.
NiSource and Sempra Energy’s initiatives in hydrogen blending exemplify their commitment to a sustainable energy future, reducing emissions while ensuring affordable and accessible solutions for consumers. If their efforts turn out successfully, they can show the significance of hydrogen in the clean energy transition.

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.
