Hydrogen hubs may help switch from Diesel

President Joe Biden’s $65 billion infrastructure bill contains $8 billion for regional hubs to develop ways to produce and distribute hydrogen fuel. One is planned for the Pacific Northwest and should help haulers and truck manufacturers in Renton and Portland in their efforts to reduce greenhouse gas emissions.

Specifically, long-distance haulers need a network of hydrogen fueling stations (like today’s truck stops) along with affordable trucks and fuel. Hub researchers’ added challenge is 95 percent of the hydrogen used in commercial vehicles comes from high temperature steamed methane where CO2 is released.

Green hydrogen, absent of CO2, uses lots of electricity to break water into hydrogen and oxygen (electrolysis), but it is expensive. In 2021, the International Energy Agency (IEA) calculated green hydrogen production costs are more than three times higher when compared to manufacturing methane derived hydrogen.

A northwest hub makes sense. Our state has an abundance of low-cost hydropower generated primarily by Columbia and Snake rivers dams. Surplus electricity from renewable sources could be directed to electrolysis plants.

For example, Douglas County PUD is constructing a pilot electrolysis plant near East Wenatchee which will use surplus power from Wells Dam located north of Chelan on the Columbia River.

According to 2021 Environmental Protection Agency (EPA) data, transportation was responsible for 30 percent of greenhouse gases in our country of which 80 percent comes from cars and trucks. Nearly a quarter of the CO2 is emitted in the transportation sector comes from medium and heavy-duty trucks.

Replacing diesel engines in long-haul trucks (Class 8) is expensive and a mammoth task. The Bureau of Transportation estimates there are roughly 4.5 million big rigs operating in the U.S. They are the trucks and trailers we commonly see on our highways carrying cargo hundreds of miles and needing short refueling times—15 minutes compared to an hour.

Hydrogen and battery powered trucks are expensive to purchase even with Washington state’s commercial vehicle tax credit covering up to $100,000 of the incremental cost for new alternative fuel vehicles.

According to the International Council on Clean Transportation, the purchase price of a Class 8 hydrogen was $359,500, compared to $474,900 for a battery operated and $143,500 for diesels. The added research should benefit truck manufactures as well.

Nikola Motors, a U.S. maker of hydrogen trucks, claims its vehicles can get 12-15 mph, well above the average 6.4 mpg for a diesel truck.

Developing hydrogen into a commercially viable fuel takes money — lots of it. Hopefully, now that hydrogen technology is growing in acceptance, there will be greater attention to accelerating research and development, scaling up production, and finding ways to reduce costs.

That’s welcome news.
