MA H3230

Establishes a Renewable Heating Standard requiring natural gas sellers to reduce carbon intensity of delivered gas by 2% starting in 2027, 7.5% by 2030, and 20% by 2035, with compliance options including renewable fuel sales, environmental attribute procurement, or alternative compliance payments

Creates the Renewable Heating Solutions Development Fund administered by the Department of Energy Resources, funded by alternative compliance payments, with administrative costs capped at 10% of fund income

Provides 30% refundable tax credits for businesses and individuals purchasing/installing qualified renewable heating equipment (air source heat pumps, ground source heat pumps, renewable hydrogen/propane systems), geothermal district heating infrastructure, and renewable heating fuel production equipment

Defines qualified renewable heating fuels as renewable natural gas (from biogas, biomass, or hydrogen methanation), renewable hydrogen (produced with renewable electricity), and renewable propane (from biogases, plant materials, or anaerobic digestion)

Requires the Department of Energy Resources to promulgate implementation regulations by July 1, 2025, conduct an inventory of renewable heating fuel sources, and establish gas quality standards for pipeline injection by July 1, 2027
