How utilities are driving carbon removal for a net-zero future

November 11, 2024

Chasing a zero-emission future is not a bare concept anymore, but a necessary step forward. With utilities being the subject of two different causes—global climate goals and innovation—at hand, this forces utilities to be at the crossroads of sustainability and innovation. But how exactly are utilities stepping up to drive carbon removal at scale, and what challenges lie ahead?

This article will answer that question and explore the groundbreaking strategies and initiatives utilities are implementing to reduce emissions and remove carbon from the atmosphere, paving the way for a cleaner, greener future.

Why carbon removal matters

Even though relying on renewable energy has been the primary approach to reducing emissions, equally important is the fact that achieving net-zero is more than just cutting the carbon output; it’s about actively removing existing carbon dioxide (CO₂) from the atmosphere. According to the IPCC, achieving the 1.5 °C global warming limit requires carbon removal solutions capable of sequestering billions of tons of CO₂ annually by mid-century.

Here lies the question: Can utilities scale solutions that meet this daunting target?

Utilities, long seen as the backbone of energy production and distribution, are uniquely positioned to spearhead this effort. The widespread issues of energy and infrastructure access, as well as the lack of public trust, leave them few other sectors to resource; thus, their newer technological deployments are on a very large scale.

Carbon capture and storage (CCS): The rising star

Carbon capture and storage (CCS) has become a fundamental means a utility company offers. This technology is responsible for the direct removal of CO₂ emissions from power plants and industrial facilities before they are about to enter the atmosphere, storing them underground in rock reservoirs.

Notable examples:

  • Norway’s longship project: This remarkable project, with Equinor as the executive along with Shell and TotalEnergies as partners, is an initiative that targets a complete CCS value chain in Europe. The plan involves capturing CO₂ from industries and storing it under the North Sea.

  • Petra Nova (U.S): Although paused due to financial hurdles, this Texas-based project demonstrated the potential of capturing over 1 million tons of CO₂ annually from a coal power plant.

Nevertheless, carbon capture and storage are not without problems:

  • High costs: The current CCS projects’ required investment has been quite substantial, sometimes even reaching the level of half a billion dollars per place.

  • Energy requirements: Procurement of CO₂ capture and sequestration technology needs energy, which may negate some of its environmental benefits.

Direct air capture (DAC)

The next frontier…

In contrast to CCS, which deals with emissions mainly at the source, direct air capture (DAC) is designed to absorb CO₂ from the air. Utilities regard DAC as a revolutionary approach to the objective of gigaton-level carbon removal. 

A standout player:

  • Partnering with energy companies, Climeworks operates the world’s largest DAC facility, capturing over 4,000 tons of CO₂ annually in Iceland and permanently storing it underground.

But, is DAC a scalable solution offering substantial results? The current range for sequestered CO₂ is $100-$600 per ton of CO₂, thereby making it economically non-viable without regulatory incentives or technological improvements.

Nature-based solutions

A complementary approach…

Corporations are also putting money into nature-based projects like reforestation, carbon farming, and wetland restoration, which is also called green infrastructure. Not that these techniques are very technologically sophisticated, but techno-savvy construction they are cost-effective, and they also provide other benefits like biodiversity and flood control. 

Examples of utility-led NBS:

  • Duke Energy: This U.S. company has committed to investing heavily in reforesting projects to neutralize its carbon footprint.

  • National Grid (UK): By connecting with farmers to start up soil carbon projects, National Grid integrates carbon reduction into the bigger picture of land use.

Leveraging infrastructure for carbon removal

More progressively, utilities are employing a strategy of tapping into existing infrastructure for carbon removal. The types of transformations are retrofitting coal and gas plants with CCS technologies or reusing the unused assets such as the abandoned oil wells for carbon storage sites.

Case Study:

Southern Company: One power producer from the U.S. ended the life cycle of several natural gas plants to use them as carbon sequestration facilities.

The role of policy and funding

Without solid policy and regulation frameworks and monetary incentives, utility companies could not hope to ensure the successful removal of carbon. In the U.S., the Inflation Reduction Act [IRA], which includes Section 45Q, has become a driver of the rapid implementation of captured CO2 tax credits up to $85 per load tonne.

However, policy gaps remain:

  • Long-term certainty: Utilities looking for consistency and reliability in funding mechanisms to validate the large investments.

  • Permitting bottlenecks: Lengthy approval processes are delaying CCS and DAC deployment.

Could accelerated permitting and additional subsidies unlock the full potential of utility-driven carbon removal?

AI and digital technologies: Driving efficiency

As utilities adopt AI and advanced analytics, they can optimize carbon removal strategies. From predictive modeling of CO₂ storage sites to real-time monitoring of emissions, digital tools are revolutionizing the sector.

Innovation in action…

ExxonMobil and AI: Artificial intelligence (AI) makes it possible for ExxonMobil to select CO₂ storage places that are environmentally optimal, thus, exploratory costs have been reduced fundamentally.

Scaling up for the future

The question remains: How can utilities scale these solutions to meet the gigaton-level removal needed by 2050?

Here are the key steps forward:

  • Public-private partnerships: Cooperation between governments and enterprises can pool resources and split the risks.

  • Community engagement: Enlightening key players on the positive aspects of carbon capture prowess will engender society’s cooperation.

  • Global collaboration: Carbon removal is not a simple activity restricted to local geography; it is a global effort. The core of it will be sharing knowledge and resources borderlessly.

The path ahead

Utilities face a monumental task, but they also have an unprecedented opportunity to lead the charge toward a net-zero future. By embracing innovative technologies, leveraging existing infrastructure, and fostering collaboration, utilities can transform carbon removal from a daunting challenge into a transformative success. Is the world ready to let utilities redefine the energy landscape for generations to come? If so, the future of the planet might be in good hands.
