Exploring New Solutions for Wind Turbine Blades

Wind farms began popping up in the 1990s and many turbines are reaching the end of their 20-30-year useful lives now. The challenge of wind turbine blade disposal has captured attention around the world, and a team at the EERC led by Joshua Strege, Principal Process Engineer, has received State Energy Research Center funding to address the need for further research into the recycling or repurposing potential of blades in North Dakota.

Difficulties for disposal include transportation, destruction, and landfilling of decommissioned blades. Strege is hoping to fill the growing demand for novel technologies to avoid landfill disposal of retired blades by finding ways each section could be repurposed to create new, high-value products. There is added public relations pressure to find a solution for keeping a renewable energy source as green as possible.

Currently, the most common method for dealing with used wind blades in the United States is landfill disposal. In Europe, blades are crushed, then burned in cement kilns. Neither of these options is ideal: Landfill disposal is not sustainable due to the size of the blades, and much of the blade structure is poorly combustible. Blades can be resold if they are still in good working order, but this is not always an option. Because blades vary so much from section to section, the ideal solution to reusing blades will likely involve separating blades into different product streams.

“I’m interested in seeing what the different components could be repurposed as—I’m not set on one specific product at this point,” said Strege. “There’s potential for reuse in something that could use the retained strength of fiberglass, instead of trying to break it down or sending whole blades to landfills.”

North Dakota has more than 1,500 turbines, with a typical turbine able to produce up to 1.5 megawatts of energy. A single blade from one of these towers can be more than 110 ft long and weigh over 6 tons. Upgrades will soon be reaching North Dakota’s turbines, and a better solution to one of the wind industry’s biggest challenges could be coming as well. As public pressure grows to find new uses for aged blades, a recycling industry will inevitably develop at some point. Finding secondary values from blades would help offset costs for decommissioning and disposing of blades in North Dakota and could set the state ahead of the curve in developing a blade recycling infrastructure.

She helped with several projects, including CarbonSAFE and the rare-earth elements project. She said the exposure to such broad areas of work allowed her to better establish her professional path. 

Zahra grew up in Zimbabwe. She said her childhood had a deep impact on her goals and is the reason she feels so strongly about making a difference and being part of innovative research that advances future energy opportunities around the world. Zahra also had the goal of playing American college sports and was recruited from Zimbabwe to play for the University of North Dakota women’s tennis team. She played her full eligibility and is now a volunteer assistant coach for the team.

PCOR: Paving the Way for CCUS

The Plains CO2 Reduction (PCOR) Partnership began in 2003 as one of seven Regional Carbon Sequestration Partnerships (RCSPs) awarded by the U.S. Department of Energy (DOE). The PCOR Partnership was led by a team of experts at the Energy & Environmental Research Center (EERC) in Grand Forks, North Dakota, and eventually boasted more than 120 public and private sector stakeholders.

Throughout its duration, the PCOR Partnership uncovered new possibilities in carbon capture, utilization, and storage (CCUS). Social acceptance, policy creation and reform—especially Class VI Primacy, and commercialization of CCUS technologies are a few of the many monumental achievements from this period. “PCOR set the stage as a world leader in that space,” said EERC CEO Charles Gorecki. “After seeing the progress made in regard to tax credits, primacy, and outreach, technical viability almost seems like the easiest thing we’ve done.”

The focus on wide-scale deployment of CCUS technologies, and the supported projects stemming from PCOR research have proven CCUS to be a valuable part of protecting our environment into the future. North Dakota CarbonSAFE, Wyoming CarbonSAFE, Project Tundra, and Red Trail Energy’s CCS Project are examples of what has been made possible with the advanced research and development techniques led by PCOR. 

“It goes beyond PCOR. It started as a DOE-funded program with the goal of reducing carbon intensity, and it has blossomed into so much more,” said Ed Steadman, EERC Vice President for Research. “It’s gone from needing to understand, ‘Is CCUS possible in this region,’ to small-scale demonstrations, then large-scale demonstrations, and now commercial efforts. The original DOE vision is being realized right now.” 

December 31, 2019, marked the end of a decade and the end of the 16-year program known as the Plains CO2 Reduction Partnership. However, the program will continue in a new way as the PCOR Initiative. In September 2019, DOE announced a $5 million grant for the PCOR Initiative to accelerate the development and commercialization of CCUS technologies. “PCOR isn’t just ending. There’s more to come,” said Gorecki.
