The company at the center of a controversial green energy project connecting New Mexico and Arizona has changed plans for a key component: A much-debated pipeline that would have carried climate-friendly hydrogen will instead carry natural gas, and possibly a natural gas-hydrogen blend at a future date. Unlike hydrogen, natural gas, blended or not, contributes to climate warming both in its production and when it is burned for energy.
The pipeline is part of a much larger project by Tallgrass Energy Partners LP that would create a hydrogen economy centered in Farmington in the northwest corner of New Mexico. Plans include hydrogen production, a massive hub to inject carbon deep underground, repurposing a mothballed coal-fired power plant as a hydrogen-fired power plant, and pipelines connecting the various parts. The plans also included one pipeline to carry hydrogen across the Navajo Nation to markets in Arizona and farther afield.Tallgrass decided to change what would be delivered in the pipeline earlier this year, and the news surprised many. Starting in 2021, the company, working through its subsidiary GreenView, carried out a public relations campaign along the proposed pipeline route through the Navajo Nation, hyping the green benefits of hydrogen. Switching to natural gas or a gas-hydrogen blend would dramatically reduce or eliminate those benefits.
