Initially a mechanical engineer, Bruno Grunau now spends his days testifying earlier than Congress, assembly frequently with the Alaska governor’s workplace, and studying from Alaska’s utilities, communities, and Indigenous folks whose ancestors have lived right here for 1000’s of years.

Grunau is the regional director of Utilized Analysis for Communities in Excessive Environments on the Nationwide Renewable Vitality Laboratory’s (NREL’s) Alaska Campus. We caught up with him to debrief the current Alaska Sustainable Vitality Convention and discover out what’s in retailer for the nation’s solely Arctic state.

What was NREL’s position on the Alaska Sustainable Vitality Convention?

Alaska is harnessing renewable assets and vitality effectivity as a solution to financial empowerment and vitality independence. The governor hosts this convention to convene vitality sectors leaders, traders and innovators, state and federal businesses, and researchers like me to plan a long-term future for the state’s vitality safety.

NREL Director Martin Keller moderated a panel on the Could 2024 convention, and NREL was properly represented among the many attendees and displays. Do you know that when COVID-19 protocols softened, Alaska Governor Dunleavy was the primary customer knocking on NREL’s door for a gathering? We now meet with the governor’s workplace twice a month.

What can we learn about renewable vitality alternatives in Alaska?

Alaska has sturdy untapped potential. For instance, the offshore marine vitality potential within the Decrease 48 states totals about 1,700 gigawatts of electrical energy. Not unhealthy. However Alaska has greater than twice as a lot, in accordance with a current evaluation of wind, wave, and tidal vitality assets that NREL carried out for the U.S. Bureau of Ocean Vitality Administration. The Prepare dinner Inlet has a few of the strongest tides on the earth! In fact, we have to determine how one can transmit marine vitality to the folks, companies, and providers that want it, however that degree of energy would help all North America.

Wow, that’s so much. What else makes Alaska’s vitality system distinctive?

Moderately than a centralized grid, Alaska’s vitality system is extra like an extension twine operating by the primary inhabitants facilities. The Railbelt energy grid that runs from Fairbanks by Anchorage to the Kenai Peninsula represents 75% of Alaska’s electrical load. We’ll must make important transmission upgrades to help the projected development in direction of better electrification—reinforcing the infrastructure for elevated circulation of electrons from gadgets like electrical automobiles and warmth pumps.

Does integrating renewables make monetary sense?

The Governor’s Workplace requested NREL to discover the financial and reliability implications of powering the Railbelt on 80% renewable vitality. In our fashions, the bills in capital prices are outweighed by the estimated $100 million saved per 12 months in gas prices, and provide and demand may be managed reliably with the suitable system engineering. Related advantages embody job creation, improved air high quality, and stabilized charges decoupled from the risky gas market.

How do rural Alaskans get energy?

Aside from the Railbelt inhabitants, Alaska has about 225 rural, largely Indigenous communities, that are primarily diesel-powered microgrids. These cities are 225 alternatives to discover alternative ways to decarbonize, and it’s already taking place in thrilling methods. I feel there may be large potential to harness photo voltaic, wind, and hydropower, coupled with vitality storage, and thrilling choices for hydrogen.

How does NREL collaborate with Indigenous Peoples of Alaska?

We work with communities which have lived on this panorama for over 10,000 years so our method is at all times to work in partnership to know their wants, present acceptable help, and work with them to merge their conventional data with the most recent accessible and acceptable know-how. One instance is our collaboration with the Asa’carsarmiut Tribe in Mountain Village to handle housing insecurity whereas codeveloping modular, energy-efficient development designs.

The imaginative and prescient of NREL’s Alaska Campus is to combine scientific analysis and cultural data to unleash a sustainable and equitable vitality transition, with an emphasis on rural, distant, and islanded communities in essentially the most excessive environments on the earth. This will imply Arctic communities though the options are replicable in islanded communities and excessive environments all around the world.

What are some applied sciences you’re enthusiastic about?

In Alaska, 80% of our vitality use goes towards house heating. We’ve some warmth pumps within the lab that work in minus 30 levels Fahrenheit—know-how that didn’t exist 10 years in the past. However the most cost-effective kilowatt-hour is the one you by no means used, so the researchers right here concentrate on constructing envelopes, optimized well being, sturdiness, and vitality effectivity that may nonetheless deal with Arctic situations.

By constructing a net-zero house, you’re a nice ambassador for vitality effectivity.

Sure, we have been one of many first primarily net-zero-rated homes in Alaska. It’s a way of life our values, however every thing we put in has paid for itself. My spouse is an architect, and I had an engineering background to attract on. Certainly one of my first tasks on the lab in Fairbanks was to judge a cellulose-based insulation materials, which is primarily created from recycled paper that preserves warmth but permits vapor to maneuver by the wall. That is vital as a result of a variety of housing points up right here stem from condensation and mildew. We persuaded the builder to put in this experimental wall system in our house and it grew to become his go-to materials since it’s straightforward to make regionally

Has the distinctive house impacted your loved ones life?

I’ve two children who grew up steeped within the values of sustainability, they usually now champion it themselves. Russell, our 8-year-old, is ready on constructing robots to avoid wasting the world from local weather change, and Annabelle, age 11, was just lately chosen to take part in a local weather science competitors hosted by NASA. I used to be fortunate sufficient to be her chaperone to the Jet Propulsion Lab for the award. I’m privileged to be round so many individuals doing wonderful work each at house and at NREL.
