Our Energy-to-Food Future

By Christopher Marquis

As climate change seeps into every aspect of our food chain, including our oceans, there is an imperative to pivot to alternative sources for nutrition to keep up with the needs of our population. One example is the use of algae in omega-3 supplements instead of fish or krill oil because it prevents overfishing and also goes straight to the source of the nutrition (fish get their omega-3’s through what they eat!).


New technology surpasses long-sought solar energy milestone

Engineers at Princeton University, supported by a grant from the U.S. National Science Foundation, have developed a new class of renewable solar energy technology. The team successfully manufactured a perovskite solar cell that can operate above industry standards for close to 30 years, a significant increase over the prior threshold of 20 years. The new technology is efficient and performs at the same level as silicon-based cells.


Maine’s First RNG Dairy Digester Now Under Construction

Peaks Renewables, a subsidiary of Summit Utilities focused on investing in technologies to decarbonize thermal energy, broke ground on Maine’s first renewable natural gas (RNG) dairy digester on July 6, 2022, in Clinton, Maine.


Climate tech firm to launch scaled-up plant sucking CO2 from air

By Kate Abnett

Construction is due to begin on Wednesday on what could become the world’s biggest plant to capture carbon dioxide from the air and deposit it underground, the company behind the nascent green technology said. Swiss start-up Climeworks AG said its second large-scale direct air capture (DAC) plant will be built in Iceland in 18-24 months, and have capacity to suck 36,000 tonnes of CO2 per year from the air.


Climeworks is building a bigger carbon removal plant — and getting some new competition

By Emily Pontecorvo

Last fall, an emerging climate solution hit a milestone when the Swiss company Climeworks switched on its “Orca” plant, an array of fans and filters that capture carbon dioxide directly from the air. Built in Iceland, it is the largest plant of its kind in the world, designed to filter 4,000 metric tons of carbon dioxide from the air each year so it can be permanently stored underground.


Will carbon capture help clean New Mexico’s power, or delay its transition?

As New Mexico lawmakers were putting the finishing touches on landmark legislation to help workers and communities transition from the closure of the state’s largest coal plant, the city of Farmington had other plans.

In the world of green tech, few sectors are hotter than direct air capture—or DAC. Think giant fans that draw planet-warming carbon dioxide out of the atmosphere, and then store the polluting material away for good, usually deep underground or on the bottom of the ocean.


There’s a carbon-capture gold rush. Some warn better solutions exist.

In recent months, the Biden administration, Elon Musk and companies such as Alphabet and Meta have poured millions — in some cases, billions — into investment funds, research proposals, grant opportunities and competitions to develop the method. Scientists argue carbon capture, which takes carbon dioxide from the air and stores it deep underground, has the potential to quickly slow Earth’s rapidly warming climate.

“Creative, interactive communication tools like virtual reality experiences offer a powerful way to spark conversations and action around climate change by helping show how a global-scale issue shows up in a very real way in our own communities,” said project leader Heidi Roop, who began the effort at the UW Climate Impacts Group and is now at the University of Minnesota.


DOE Announces $39 Million for Research and Development to Turn Buildings into Carbon Storage Structures

The U.S. Department of Energy (DOE) today announced $39 million in awards for 18 projects seeking to develop technologies that can transform buildings into net carbon storage structures. Led by DOE’s Advanced Research Projects Agency-Energy (ARPA-E), selectees for the Harnessing Emissions into Structures Taking Inputs from the Atmosphere (HESTIA) program will prioritize overcoming barriers associated with carbon-storing buildings, including scarce, expensive and geographically limited building materials. Decarbonization goals for the HESTIA program mirror President Biden’s plan to reach zero emissions by 2050 and aim to increase the total amount of carbon stored in buildings to create carbon sinks, which absorb more carbon from the atmosphere than released during the construction process.
