Explore heavy equipment electrification technologies

Big machines take different paths to electric vehicles

Much current electric vehicle (EV) work is focused on passenger vehicles. While these are the largest contributors to transport-related emissions, sustainability initiatives should also make room for heavy industrial equipment.

Proportion of construction machinery and other off-road vehicles Accounts for 10% of all transport greenhouse gas emissions– The rail and maritime sectors combined doubled. Thankfully, electric alternatives to traditional machines are starting to hit the market. This shift stems from a few key technological improvements.

next generation battery

As in consumer vehicles, battery-electric alternatives are the most important electrification solution in heavy equipment. However, traditional electric vehicle batteries are difficult to meet the needs of industrial machines working for long periods of time under harsh working conditions.

Modular batteries offer some key improvements. These components are Interchangeable between machines of various sizesallowing teams to swap modules between vehicles without stopping to recharge. This setup also means that the backup battery can be charged off-site to maintain its quality before work requires it.

Batteries with higher power density, better operating temperature ranges and faster charging times are also making electrification increasingly feasible. Falling prices also make electric vehicles a better choice for projects on a tight budget.

hydrogen fuel cell

Hydrogen energy is another growing solution. Fuel cells are ideal for heavy machinery that cannot sit idle for long periods of time charging, as refueling only takes a few minutes. Hydrogen too The world’s most energy dense fuel (for its quality), allowing the equipment to run longer between refueling stops.

Historically, fuel cells have been too expensive to implement in most applications, but that is changing as research makes fuel cells cheaper and more efficient. The global energy industry has Emissions reduced by 30% Due to the widespread adoption of hydrogen energy.

Heavy machinery (which businesses often lease and require extra power) is also better suited to hydrogen than road vehicles. Therefore, it may enter industrial use cases before commercial vehicles.

Mixing equipment

Hybrids are also worth considering. While combining an internal combustion engine with an electric motor still produces some emissions, it allows companies to reduce their carbon footprint without having to invest a lot of money or make significant changes to work processes. The technology is therefore a useful stepping stone towards an all-electric future.

Businesses also recognize this opportunity. Hybrid cars are Fastest growing electrical construction equipment segmentprobably due to people’s familiarity with them and the fact that many manufacturers make them. Lowering emissions from these machines could help heavy industry move closer to environmental targets, and then improvements in batteries and fuel cells make these options more commercially viable.

Equipment electrification still faces challenges

Innovations in battery, fuel cell and hybrid technologies are making the dream of efficient power equipment a reality. However, the industry has not yet overcome all challenges. While cost may be the biggest barrier in consumer applications, accessibility is a bigger issue for industrial-grade machinery.

The lack of charging infrastructure near the site makes it difficult to justify a fleet of electric motors. Most needed Fully charged in eight hours Large EV batteries used in heavy equipment (240V Level 2 charging), some heavy equipment batteries may require more time. There’s just no time for most construction projects. Faster-charging batteries or portable fast chargers may be needed to overcome this hurdle.

Hydrogen offers a potential solution, but its applications are smaller. There are also relatively few manufacturers producing fuel cell-powered equipment. The market needs to mature before companies can make significant changes to their fleets.

The future of heavy equipment is electric

Despite these challenges, electric heavy equipment has made impressive progress. Further research, advancements and market growth will ultimately pave the way for low-emission industrial jobs. When this shift will occur remains uncertain, but organizations already have the option to reduce their carbon footprint while maintaining productivity.
