The construction industry is notoriously carbon-intensive, but it doesn't have to be. As environmental concerns grow, it's increasingly crucial for companies to go green, and new technologies make that possible. One of the most promising of these technologies is hydrogen fuel cells.
Fuel cells generate electricity from a chemical reaction between hydrogen and oxygen. If they use sustainably obtained hydrogen, then they're entirely carbon-free, emitting only electricity, heat and water as byproducts. As these technologies become more affordable and efficient, their uses grow.
Construction companies can use fuel cells to become more eco-friendly. Here are five potential use cases for the technology.
ZERO-EMISSIONS GENERATORS
Construction sites use a considerable amount of energy to power lights, appliances and other electrical equipment. The industry standard has been to use diesel or gasoline generators to provide this electricity. If teams turned to fuel cell-powered generators instead, they could easily reduce their carbon footprint.
A major construction project in the United Kingdom adopted hydrogen generators in August in an attempt to go green.
The power source resides in a shipping container and can provide enough energy for the entire project. Portable solutions like this are readily available and won't disrupt regular work to use.
HYDROGEN VEHICLES
Most conversations about hydrogen power revolve around fuel cell-powered vehicles, which can also apply to construction. While most hydrogen vehicles today are for consumers, there have been developments in hydrogen-powered construction equipment. Most recently, Hyundai unveiled a mid-sized hydrogen forklift capable of lifting five tons.
Smaller fuel cell forklifts are already available for use, and more options will emerge in the future. With further advancement, construction companies could see fuel cell-powered excavators, cranes or bulldozers. Fuel cells can effectively power anything that uses a combustion engine.
ECO-FRIENDLY FACILITIES
The same U.K. project that adopted hydrogen generators also implemented fuel cell cabins on the worksite. These facilities provide kitchens, toilets and changing rooms to workers. Running all of those features on fossil fuels would generate considerable amounts of emissions, but they're carbon-free with fuel cells.
Construction companies could use fuel cell technology to provide more facilities for workers. Since they wouldn't increase their carbon footprint, construction teams could more comfortably install more amenities like this. Employee morale—and productivity—would rise, but carbon emissions wouldn't.
FUEL CELL-POWERED BUILDINGS
The potential for fuel cells in construction doesn't stop at the building process itself, either. Firms could start constructing buildings that rely on hydrogen power, and there's already precedent for this. The UC Irvine Medical Center has drawn 30% of its energy from a fuel cell pla
