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.

How Climate Change Is Raising the Cost of Living
Americans are paying more for insurance, electricity, taxes, and home repairs every year. What many people may not realize is that climate change is already one of the drivers behind those rising costs.
For many households, climate change is no longer just an environmental issue. It is becoming a cost-of-living issue. While climate impacts like melting glaciers and shrinking polar ice can feel distant from everyday life, the financial effects are already showing up in monthly budgets across the country.
Today, a larger share of household income is consumed by fixed costs such as housing, insurance, utilities, and healthcare. (3) Climate change and climate inaction are adding pressure to many of those expenses through higher disaster recovery costs, rising energy demand, infrastructure repairs, and increased insurance risk.
The goal of this article is to help connect climate change to the everyday financial realities people already experience. Regardless of where someone stands on climate policy, it is important to recognize that climate change is already increasing costs for households, businesses, and taxpayers across the United States.
More conservative estimates indicate that the average household has experienced an increase of about $400 per year from observed climate change, while less conservative estimates suggest an increase of $900.(1) Those in more disaster-prone regions of the country face disproportionate costs, with some households experiencing climate-related costs averaging $1,300 per year.(1) Another study found that climate adaptation costs driven by climate change have already consumed over 3% of personal income in the U.S. since 2015.(9) By the end of the century, housing units could spend an additional $5,600 on adaptation costs.(1)
Whether we realize it or not, Americans are already paying for climate change through higher insurance premiums, energy costs, taxes, and infrastructure repairs. These growing expenses are often referred to as climate adaptation costs.
Without meaningful climate action, these costs are expected to continue rising. Choosing not to invest in climate action is also choosing to spend more on climate adaptation.
Here are a few ways climate change is already increasing the cost of living:
- Higher insurance costs from more frequent and severe storms
- Higher energy use during longer and hotter summers
- Higher electricity rates tied to storm recovery and grid upgrades
- Higher government spending and taxpayer-funded disaster recovery costs
The real debate is not whether climate change costs money. Americans are already paying for it. The question is where we want those costs to go. Should we invest more in climate action to help reduce future climate adaptation costs, or continue paying growing recovery and adaptation expenses in everyday life?
How Climate Change Is Increasing Insurance Costs
There is one industry that closely tracks the financial impact of natural disasters: insurance. Insurance companies are focused on assessing risk, estimating damages, and collecting enough revenue to cover losses and remain financially stable.
Comparing the 20-year periods 1980–1999 and 2000–2019, climate-related disasters increased 83% globally from 3,656 events to 6,681 events. The average time between billion-dollar disasters dropped from 82 days during the 1980s to 16 days during the last 10 years, and in 2025 the average time between disasters fell to just 10 days. (6)
According to the reinsurance firm Munich Re, total economic losses from natural disasters in 2024 exceeded $320 billion globally, nearly 40% higher than the decade-long annual average. Average annual inflation-adjusted costs more than quadrupled from $22.6 billion per year in the 1980s to $102 billion per year in the 2010s. Costs increased further to an average of $153.2 billion annually during 2020–2024, representing another 50% increase over the 2010s. (6)
In the United States, billion-dollar weather and climate disasters have also increased significantly. The average number of billion-dollar disasters per year has grown from roughly three annually during the 1980s to 19 annually over the last decade. In 2023 and 2024, the U.S. recorded 28 and 27 billion-dollar disasters respectively, both setting new records. (6)
The growing impact of climate change is one reason insurance costs continue to rise. “There are two things that drive insurance loss costs, which is the frequency of events and how much they cost,” said Robert Passmore, assistant vice president of personal lines at the Property Casualty Insurers Association of America. “So, as these events become more frequent, that’s definitely going to have an impact.” (8)
After adjusting for inflation, insurance costs have steadily increased over time. From 2000 to 2020, insurance costs consistently grew faster than the Consumer Price Index due to rising rebuilding costs and weather-related losses.(3) Between 2020 and 2023 alone, the average home insurance premium increased from $75 to $360 due to climate change impacts, with disaster-prone regions experiencing especially steep increases.(1) Since 2015, homeowners in some regions affected by more extreme weather have seen home insurance costs increased by nearly 57%.(1) Some insurers have also limited or stopped offering coverage in high-risk areas.(7)
For many families, rising insurance costs are no longer occasional financial burdens. They are becoming recurring monthly expenses tied directly to growing climate risk.
How Rising Temperatures Increase Household Energy Costs

The financial impacts of climate change extend beyond insurance. Rising temperatures are also changing how much energy Americans use and how utilities plan for future electricity demand.
Between 1950 and 2010, per capita electricity use increased 10-fold, though usage has flattened or slightly declined since 2012 due to more efficient appliances and LED lighting. (3) A significant share of increased energy demand comes from cooling needs associated with higher temperatures.
Over the last 20 years, the United States has experienced increasing Cooling Degree Days (CDD) and decreasing Heating Degree Days (HDD). Nearly all counties have become warmer over the past three decades, with some areas experiencing several hundred additional cooling degree days, equivalent to roughly one additional degree of warmth on most days. (1) This trend reflects a warming climate where air conditioning demand is increasing while heating demand generally declines. (4)
As temperatures continue rising, households are expected to spend more on cooling than they save on heating. The U.S. Energy Information Administration (EIA) projects that by 2050, national Heating Degree Days will be 11% lower while Cooling Degree Days will be 28% higher than 2021 levels. Cooling demand is projected to rise 2.5 times faster than heating demand declines. (5)
These projections come from energy and infrastructure experts planning for future electricity demand and grid capacity needs. Utilities and grid operators are already preparing for higher peak summer electricity loads caused by rising temperatures. (5)
Longer and hotter summers also affect how homes and buildings are designed. Buildings constructed for past climate conditions may require upgrades such as larger air conditioning systems, stronger insulation, and improved ventilation to remain comfortable and energy efficient in the future. (10)
For many households, this means higher monthly utility bills and potentially higher long-term home improvement costs as temperatures continue to rise.
How Climate Change Affects Electricity Rates
On an inflation-adjusted basis, average U.S. residential electricity rates are slightly lower today than they were 50 years ago. (2) However, climate-related damage to utility infrastructure is creating new upward pressure on electricity costs.
Electric utilities rely heavily on above-ground poles, wires, transformers, and substations that can be damaged by hurricanes, storms, floods, and wildfires. Repairing and upgrading this infrastructure often requires substantial investment.
As a result, utilities are increasing electricity rates in response to wildfire and hurricane events to fund infrastructure repairs and future mitigation efforts. (1) The average cumulative increase in per-household electricity expenditures due to climate-related price changes is approximately $30. (1)
While this increase may appear modest today, utility costs are expected to rise further as climate-related infrastructure damage becomes more frequent and severe.
How Climate Disasters Increase Government Spending and Taxes
Extreme weather events also damage public infrastructure, including roads, schools, bridges, airports, water systems, and emergency services infrastructure. Recovery and rebuilding costs are often funded through taxpayer dollars at the federal, state, and local levels.
The average annual government cost tied to climate-related disaster recovery is estimated at nearly $142 per household. (1) States that frequently experience hurricanes, wildfires, tornadoes, or flooding can face even higher public recovery costs.
These expenses affect taxpayers whether they personally experience a disaster or not. Climate-related recovery spending can increase pressure on public budgets, emergency management systems, and infrastructure funding nationwide.
Reducing Climate Costs Through Climate Action
While this article focuses on the growing financial costs associated with climate change, the issue is not only about money for many people. It is also about recognizing our environmental impact and taking responsibility for reducing it in order to help preserve a healthy planet for future generations.
While individuals alone cannot solve climate change, collective action can help reduce future climate adaptation costs over time.
For those interested in taking action, there are three important steps:
- Estimate your carbon footprint to better understand the emissions connected to your lifestyle and activities.
- Create a plan to gradually reduce emissions through energy efficiency, cleaner technologies, and more sustainable choices.
- Address remaining emissions by supporting verified carbon reduction projects through carbon credits.
Carbon credits are one of the most cost-effective tools available for climate action because they help fund projects that generate verified emission reductions at scale. Supporting global emission reduction efforts can help reduce the long-term impacts and costs associated with climate change.

Carbon credit project stewardship: what happens after credit issuance
A carbon credit purchase is not a transaction that closes at issuance. The credit may be retired, the certificate filed, and the reporting box ticked. But on the ground, in the forest, in the field, and in the community, the work continues. It endures for years. In many cases, for decades.
