Midwest looks to New England for biomass roadmap

Wood fuel represents just a sliver of the Midwest’s heating market. By BTUs, solid biomass supplied 3 percent of the region’s heat in 2010, according to the U.S. Energy Information Administration. The rest came primarily from non-renewable, fossil fuels — mostly natural gas.

A biomass advocacy group called Heating the Midwest thinks the region could and should significantly boost the share of heat it gets from wood-burning stoves and boilers, and it unveiled a vision at its annual conference in Minnesota last week for how to get to a 10 percent thermal biomass goal by 2025.

“If the Midwestern region is serious about achieving a cleaner, more sustainable energy future, it must focus new and significant attention on thermal energy,” the group said in its report, which claims there would be environmental and economic benefits from transitioning to use of more renewable biomass for heating.

The group’s vision also calls for generating 5 percent of heating energy from solar thermal and geothermal, bringing renewables’ share to 15 percent.

Thermal energy accounts for about 38 percent of all energy consumed in the Midwest. Yet most energy policy efforts in the region have focused on electricity and transportation. Nationally, thermal energy gets even less attention because it has little impact on warm-weather states.

The Northeast as an example

Heating the Midwest is looking to the Northeast as a successful example of where regional coordination and investment is helping to grow a wood-fuel industry. Its vision document was prepared by a Maine biomass research and consulting group, FutureMetrics, that did a similar roadmap for the Northeast in 2010.

Wood fuel provides about 4 percent of heating energy in the Northeast (six New England states and New York), where biomass supporters have announced a goal of providing 18 percent of thermal power by 2025.

In the Northeast, however, biomass has much less competition from natural gas. Only about 57 percent of homes and businesses there are heated by natural gas, compared to 72 percent in the Midwest. Low natural gas prices have hurt the financial case for biomass projects in much of the region.

Still, about 15 percent of Midwest homes and businesses use electric heat and another 11 percent use fuel oil or LPG (liquefied petroleum gases). In total, more than 12.6 million customers in the region are not connected to natural gas pipelines, including more than half of customers in North and South Dakota.

Number of Homes and Businesses NOT connected to Natural Gas

The Midwest biomass group sees potential to grab market share by converting these off-pipeline customers to wood pellet or chip fuels, which are less expensive than heating oil, propane and electric heat. (Two northern Minnesota towns, for example, are studying biomass options as an alternative to trucking in fossil fuels.)

‘It’s still a jump for some people’

When biomass is sustainably harvested, it can have significant environmental benefits. Modern biomass burners emit fewer particulates than those built decades ago, and they emit less sulfur dioxide and mercury than fossil fuels, the report says.

Also, the combustion of biomass doesn’t add any new carbon dioxide into the atmosphere — it only re-releases the carbon previously absorbed by the plants that serve as the fuel source. The overall climate impact of burning biomass is largely determined by the amount of energy that goes into harvesting, processing and shipping it.

The region has enough farms and forests to sustainably harvest enough biomass to heat 1,161,000 average-sized homes, according to the report. Ramping up the biomass industry to meet that demand would create hundreds of new logging, chipping and trucking jobs, it says.

Customers would save money on heating fuel costs, and the savings would likely grow as fossil fuel prices climb. But there would be upfront costs for converting or replacing existing equipment, and that’s one of the big barriers.

“It’s very hard to get people to invest in systems that are currently working,” said T.J. Morice, vice-chair of Heating the Midwest’s steering committee and also a vice president at a Wausau, Wisconsin, wood products company. “As good as it looks on paper, it’s still a jump for some people.”

Policy support

Another issue is fuel supply. While the Midwest has plenty of biomass, someone still has to harvest, process and deliver it. Bulk distribution of wood chips and pellets is still in its infancy and will require “broad market adoption” to attract the necessary capital investment in storage and transportation equipment, the report says.

In the Northeast, Maine, Vermont and New Hampshire have already bridged that gap, with more than a dozen modern pellet delivery trucks operating there.

Progress in those states has been driven in part by supportive policy. New Hampshire supports thermal renewables with revenue from its renewable electricity standard and greenhouse gas initiatives. Northeast states also used federal stimulus dollars to fund several biomass projects, including 23 pellet and wood chip heating plants in Maine and 125 pellet boiler systems in New Hampshire.

“They’ve been able to make a little more progress from the policy standpoint,” Morice said. “They’ve made some bigger strides, and that’s what we aspire to do here with this effort.”

The Heating the Midwest 2025 vision lists several “critical public policy elements” that are needed to achieve the target. They include:

  • Supporting research on the region’s biomass supply, along with sustainable forest management, biomass harvesting and procurement guidelines.
  • Developing a Renewable Thermal Standard, similar to existing Renewable Fuels Standard or state renewable electricity standards.
  • Create federal and state incentives, grants and loans to encourage installations of high-efficiency biomass thermal systems.

Morice said part of the problem is that wood-fuel systems don’t have “policy parity” with other technologies. In Wisconsin, he said, customers can get rebates to replace an old petroleum burner with a newer, more efficient petroleum burner, but they can’t get assistance with installing a pellet unit.

Heating the Midwest held its second annual conference last week in Carlton, Minnesota, about 20 miles south of Duluth. The volunteer group came together a few years ago to promote thermal biomass heating in the region. Its steering committee includes industry, government, nonprofit and academic representatives.

Steering committee chair Brian Brashaw, a program director at the University of Minnesota-Duluth’s Natural Resources Research Institute, said he’s “bullish” on biomass and pointed to notable biomass installations such as District Energy in St. Paul and another at Wolf Ridge Environmental Learning Center in Ely, Minnesota.

“We have success stories,” Brashaw said. “We just don’t have enough of them.”

This is great work. It is very surprising that Ohio has so many homes and businesses that do not have natural gas access, given that this state has much infrastructure across and through it. More detailed work may help to further focus the opportunity by considering businesses and manufacturers who do not have access to gas and the likelihood of future natural gas pipeline expansions. The recent example of Jack Links in Wisconsin (a beef jerky maker) shows that some large heat consumers in the Midwest do not have natural gas access, as well as the cost for bringing access (We Energies is extending a gas line at a cost of many millions).

I’m pretty sure North Dakota will soon be connecting more cities to natural gas pipelines. They are flaring it in western ND now because there is no market for it. They must add pipelines! Also, regarding North and South Dakota not being connected to natural gas… 650,000 people is not enough to ship wood biomass to either. Unless the wood is grown locally and sustainably harvested, it won’t be a profitable investment.

Frankly, I think utility scale wind turbine installations make more sense in ND, SD, NE, KS, OK & TX. Locally, those residents should have solar thermal and solar photovoltaic systems on their roofs to reduce peak demand on the grid. Ground source geothermal heating and cooling systems are pretty efficient also.
