HELE technologies are important because they are commercially available and a key steppingstone to meet energy needs as well as emissions goals. In fact, 24 countries have included coal-fueled power plants in their nationally determined contributions as part of the Paris Agreement.
Achieving near-zero emissions from coal also will require implementation of carbon capture, use and storage (CCUS) technologies. Plants, like Petra Nova in Texas, are showing that CCUS coal-fueled plants are technically viable and are the first step in the technology cost buydown curve based on the lessons learned that drive down costs for future projects. In the end, we need dozens more plants like Petra Nova.
In the United States, the passage of the FUTURE Act legislation has resulted in renewed momentum for CCUS and is expected to result in new CCUS projects. Additionally, a new type of power plant is under development that would be efficient, modular and flexible. Being advanced by the U.S. Department of Energy, these plants could offer considerable value not only in America but around the world.
Many other initiatives in the technology development pipeline have potential for carbon capture and reduced emissions. Examples include solutions from post-combustion concepts such as membranes, dry sorbents, non-aqueous liquid systems to transformational options like chemical looping and pressurized oxy-combustion. Several of these have advanced to the pilot and demonstration scale and with appropriate funding can be advanced to successful implementation.
But policy and practicality aren’t always on the same page. While the rest of the world is turning to coal, the U.S. hasn’t yet fully shifted its thinking or policies along those lines. We need to continue to encourage investments in coal-fueled plants and remove regulatory barriers such as New Source Review, which deters power plants from making upgrades that could improve efficiency and reduce emission as a result. New Source Review also discourages changes that would make power plants more flexible, allowing them to respond to the influx in intermittent renewables. The U.S. Environmental Protection Agency (EPA) is starting to address these concerns, along with a repeal and some form of replacement of the Clean Power Plan. The changes are welcome and can’t come soon enough.
Across the world, we need to make sure we are taking actions that support viable, healthy economies driven by affordable power. Mistakes learned by those who have turned away from coal should be well heeded by policymakers.
Take for instance, circumstances as recently seen in Australia where a country rich in natural resources and one that pays some of the highest electricity rates in the world has faced blackouts. Conditions in certain regions of the U.S. expose similar vulnerabilities. The bomb cyclone which struck much of the eastern U.S. late last year is an example. Temperatures plummeted and demand for heating power soared. During that period, coal-fueled power fortunately kept the lights on and homes comfortably warmed.
In addition, Texas has warned of increased risks of price spikes and reliability issues due to record summer demand amid early coal plant retirements.
These signals of threats to power supply and grid resiliency are a real risk, especially when viewed with the thought of evolving replacement of fuel-secure sources with fuel-insecure sources. We must work together to ensure we have the power generation to meet the world’s needs, both on a day-to-day basis and during high-impact, low-frequency events.
These are vital points to be made when we meet with policymakers, opinion leaders, friends and family as part of a common-ground approach to rational thought on energy and the environment.
Coal is not without its significant headwinds. But as I look at the state of the global coal industry, I see a cup – perhaps a haul truck – half full or more.
Coal has a significant role to play in the world and will for many decades to come. Coal helps the world achieve multiple UN sustainable development goals such as ensuring access to affordable, reliable, sustainable and modern energy; promoting inclusive and sustainable economic growth and employment; and building resilient infrastructure. And advanced coal technologies are a major part of the solution for environmental improvement.
