There’s nice uncertainty in Massachusetts’ path to decarbonization, and two conflicting visions are rising for the way forward for the state’s fuel system. Central to the battle are questions over the function of other gases within the transition to wash power, in addition to the way forward for the fuel trade as a complete. And as invisible because the fuel is itself, among the trade’s affect on the power transition has been hidden from view, as underscored by emails launched this week by a watchdog group.
Whereas the state’s fuel utility corporations argue that fuels like hydrogen and biomethane are the state’s finest guess to quickly decarbonize its heating and different gas-dependent sectors, local weather advocates contend these corporations are pushing false options to guard their earnings, and that the fuel system ought to as an alternative finally be decommissioned.
“If we settle for the trade’s case that we must always use these applied sciences, that mainly prolongs our dependance on pure fuel,” mentioned Dr. Phil Landrigan, the director of the World Observatory on Planetary Well being at Boston Faculty. “It locks us into fuel exactly at a time once we ought to be ending our habit to fossil fuels and transferring to renewables.”
As fuel utilities and advocates debate the way forward for the fuel system, state regulators have deferred to the utilities to assemble the preliminary plans for decarbonization. In a wide range of avenues all through the state, utilities have used their affect to advertise their most popular decarbonization choices, typically out of the general public eye. Environmentalists argue that is placing the state’s local weather targets in jeopardy.
“Is a fuel utility going to plan in opposition to its finest pursuits for the sake of the Commonwealth’s decarbonization targets, or for the sake of ratepayers within the Commonwealth?” requested Kyle Murray, a senior coverage advocate on the Acadia Middle, a nonprofit that focuses on local weather and power coverage. “I’m undecided that’s even truthful to them, as they’ve shareholders that they should ship a revenue to. So there’s a elementary downside with who attracts up the plans.”
Inexperienced Gasoline or Greenwashing?
Hydrogen fuel, already utilized in some industrial processes, emits water vapor when combusted, and has garnered vital consideration for its potential to assist remove greenhouse fuel emissions from hard-to-decarbonize sectors like metal manufacturing and transport. The fuel trade has additionally proven a eager curiosity in utilizing hydrogen for residential and industrial heating.
Whereas utilities tout the fuel for its local weather advantages, practically all hydrogen gasoline is presently made by burning fossil fuels. Inexperienced hydrogen, the one kind produced by renewables, makes up lower than 1 % of hydrogen produced at present. Inexperienced hydrogen is made out of splitting water molecules and requires large quantities of unpolluted power. Latest research have forged doubt on its potential for dwelling heating—a current overview article printed in Joule discovered it unsuitable for this function.
One other current research, printed in Nature Power, discovered that inexperienced hydrogen is projected to comprise lower than one % of worldwide power by 2035, even assuming exponential development.
Dr. Gregory Nemet, one of many research’s co-authors, wrote in an e mail that for inexperienced hydrogen to have a measurable local weather impression, “it might want to develop just like the very quickest expertise growth instances of the previous, corresponding to shipbuilding in World Conflict II and growth of the Covid-19 vaccines in 2020.”
Contradicting utility proposals, Nemet doubts that inexperienced hydrogen will probably be a significant factor sooner or later heating sector, noting that “it could be competing immediately with electrical heating … that may possible have persistently decrease set up prices and working prices.”
Biomethane–typically known as renewable pure fuel–additionally faces main obstacles to extensive scale adoption. Biomethane is fuel captured from natural waste amenities corresponding to landfills, wastewater remedy facilities and agricultural operations. This captured fuel is then processed to have a chemical composition much like pure fuel. The main constraint, nonetheless, is that there’s a restricted quantity of decomposing natural waste from which to seize the fuel. As an example, if all of California’s out there waste emissions have been captured, this is able to solely cowl about 3 % of the state’s pure fuel demand.
Limits to manufacturing and a rising demand throughout a number of sectors might hold biomethane costs considerably larger than pure fuel. This may put a further pressure on shoppers, and threat making a perverse incentive for waste managers to truly enhance their methane emissions in an effort to meet a ravenous marketplace for the gasoline.
Whereas biomethane is mostly accepted to have a smaller warming impression than pure fuel, its combustion nonetheless produces CO2, and leaks in transportation methods for the fuel diminish its local weather advantages. Moreover, combusting biomethane in houses might perpetuate among the damaging well being results of pure fuel.
Combustion of hydrogen additionally poses well being and security dangers, and might produce even larger quantities of polluting byproducts than pure fuel when burned. Moreover, hydrogen fuel could cause transporting infrastructure, corresponding to pipes, to embrittle and turn out to be extra leak susceptible, and should pose a fair larger threat of in-home explosions than pure fuel. As a consequence of infrastructure constraints, utilities don’t anticipate mixing in additional than 20 % of hydrogen into the fuel provide for heating with out main upgrades to the system. A 20 % mix of inexperienced hydrogen with pure fuel would solely end in a few 7 % discount in emissions due to hydrogen’s decrease power density.
“One of many issues that basically alarmed us once we have been first doing this analysis is that hydrogen, when it’s combusted, has about six instances the NOx emissions as methane,” mentioned Abbe Ramanan, a venture director on the nonprofit Clear Power Group.
NOx is the title used broadly for various kinds of nitrogen oxides, greenhouse gases produced within the combustion of many forms of gasoline. NOx gases heat the environment at a degree akin to methane and are main contributors to each bronchial asthma and acid rain.
Within the coastal city of Peabody, Massachusetts, residents have been combating the development of a pure fuel “peaker” plant, supposed to supply electrical energy when spikes in demand overtax different electrical energy era amenities, which can finally substitute one 0f two current vegetation on the website. Within the one public assembly held in regards to the new plant, representatives of the municipal utility known as changing the plant to one hundred pc inexperienced hydrogen post-construction their “final purpose.”
Elevated NOx emissions within the space would put a further burden on a group that’s already going through the results of heavy air air pollution. A current evaluation commissioned by the Massachusetts Local weather Motion Community discovered residents close to current vegetation in Peabody already face elevated dangers of stroke, most cancers and different illnesses.
“The explanation peaker vegetation are so detrimental to the encircling communities is due to these NOx emissions,” Ramanan mentioned.
Controversy Over the Way forward for Fuel
Latest proceedings on the state’s Division of Public Utilities (DPU) trying into decarbonizing the fuel system have relied on the fuel utilities to draft their very own preliminary plans, regardless of objections from local weather advocates, whereas minimizing the function of environmental teams.
Massachusetts fuel utilities—together with power giants Nationwide Grid, Eversource and a subsidiary of Iberdrola—base their plans on a research carried out by consultants employed by the trade. The plans place a powerful emphasis on a “hybrid electrification” technique, wherein the fuel distribution community can be largely maintained to again up electrical warmth pumps.

“We plan to remove fossil fuels from our current fuel community no later than 2050 by delivering renewable pure fuel and inexperienced hydrogen to our prospects,” wrote Christine Milligan, a spokesperson for Nationwide Grid, in an e mail. “Continued use of the fuel community utilizing fossil free fuels will assist scale back electrical system infrastructure investments—and helps help an inexpensive pathway to internet zero.”
In response to Milligan, power effectivity measures are additionally key elements of the businesses’ plans, alongside networked geothermal and focused electrification choices the place it deems the applied sciences are possible. Networked geothermal is basically a system of linked ground-source warmth pumps that use electrical energy to warmth and funky houses, whereas focused electrification refers to completely electrifying heating in sure areas in an effort to decommission choose components of the fuel system.
Altogether, sustaining the state’s fuel system is not going to be low-cost. In response to one evaluation, a state pipeline substitute program will price prospects about $20 billion.
Moreover, local weather and environmental justice advocates argue the report commissioned by the utilities presents a distorted view of decarbonization; underestimating fuel leak charges, neglecting out-of-state emissions of gases which might be used within the state, assuming a net-zero impression of all various fuels and declining to quantify the well being impacts of air air pollution. In addition they argue the report ought to have thought of job creation and financial impacts previous 2050.
The trade consultants’ modeling depends on the Massachusetts Greenhouse Fuel Stock for a lot of of those inputs, however current analysis reveals that the state’s stock itself considerably undercounts emissions.
“Think about medical doctors not utilizing the innovative information to make choices for his or her sufferers,” mentioned Andee Kranser of Higher Boston Physicians for Social Accountability. “They’re utilizing these outdated inputs for his or her fashions to say that this is able to work.”
As strain for local weather motion has elevated over the previous decade, Massachusetts utility corporations have used their immense energy within the state to affect clear power and decarbonization coverage.
Within the state’s most up-to-date legislative session, utilities corporations used their costly lobbying operations to oppose sure clear power insurance policies, together with payments selling rooftop photo voltaic and a transition off of greenhouse gas-emitting fuels. Some Massachusetts utility corporations basically skirt the state’s lobbying disclosure necessities by registering practically all of their lobbying work as “impartial,” as an alternative of exposing help or opposition for particular insurance policies.
One failed invoice utility lobbyists supported—launched by state Rep. Tom Golden Jr., former co-chair of the Joint Committee on Telecommunications, Utilities and Power, the legislative committee tasked with overseeing the trade—would have incentivized hydrogen and biomethane within the heating sector, and created a state fund to spur funding within the applied sciences.
Just lately uncovered emails printed by the Boston Globe point out that this invoice was based mostly on suggestions from a College of Massachusetts Lowell research that was developed in shut coordination with and largely funded by pure fuel and pipeline utilities in a not utterly disclosed relationship. Some researchers have criticized the research for ignoring analysis that discovered dangers in transferring hydrogen by way of fuel pipelines, and the quantity of power required to make sufficient of the fuel to warmth houses. Golden, together with each the present state home and senate chairs of the identical committee—state Sen. Michael Barrett and state Rep. Jeffrey Roy—all participated in a UMass Lowell panel on the paper and its findings.
This invoice displays the fuel trade’s basic technique on biomethane. In a coverage panel targeted on combating fuel bans earlier this yr, Sheri Givens, Nationwide Grid vice chairman of U.S. coverage & regulatory technique, laid out the tactic, noting that renewable pure fuel, or RNG, is about 4 instances dearer than pure fuel, however that aggressive incentives, corresponding to an ordinary requiring elevated quantities of biofuels within the fuel system, might assist increase the useful resource.
“If we are able to begin valuing RNG for heating, and bringing these incentives to assist deliver the price down for the builders, that’s how we’re gonna get extra RNG into our system,” she mentioned.
In the meantime, pure fuel from non-renewable sources continues to make up basically all the state’s fuel provide, and fuel connections in Massachusetts are growing, a development which the trade expects to proceed within the close to future. The state’s fuel utilities make their cash not on the fuel they distribute, however on the prices related to distribution, so a discount in fuel quantity that retains the distribution community in place wouldn’t essentially harm their backside line.
As pure fuel costs skyrocket throughout New England, international emissions are additionally on the rise—projected to extend 10 % globally by 2030, even when international locations meet their local weather commitments—with devastating penalties.
“This greater than something speaks to the necessity of the clear power transition being taken out of the arms of the utility corporations,” mentioned Logan Malik, director of the Massachusetts Local weather Motion Community. “They’re profit-driven and this cuts into their revenue as a fuel firm. However the local weather disaster is right here, and we have to take swift motion to transition, and fuel corporations will not be going to guide us to the options that we’d like as a commonwealth and as a rustic.”
In the intervening time, approval of the utilities’ plans is now as much as the DPU. However with a brand new Democratic administration taking workplace this winter and two of the DPU’s three commissioners reaching the tip of their phrases, the way forward for fuel in Massachusetts stays unsure.
