H2 ZERO PARKLET

The H2 ZERØ Parklet is an innovative solution that unites intelligent design to a hydrogen system in a business model that can enable smart cities to fight back against cars for city space. H2 ZERØ occupies one or two regular parking spots adding value to people’s quality of life by providing a space where people can interact with each other, relax, and get information about the city, instead of using valuable space with idle cars.So why a parklet? These are relatively cheap ways to provide more open space for the public in urban areas where this has become rare. In a parklet, parking spots which are exclusive spaces dedicated to polluting cars, are transformed in quality of life for citizens. Research has proved that parklets help increase economic activity in their areas by fomenting foot traffic, especially in commercial spaces. The additional movement helps reduce car travel speeds, increasing safety for both pedestrians and drivers. The micro-mobility trend seen in modern cities can be incorporated into parklets, providing parking and charging to service providers. Parklets offer an attractive solution for encouraging orderly parking of e-scooters, bikes, and other modes. H2 ZERØ is also a canvas for the public and private sector to reach their public creatively. By enabling a few tailored features in a pre-assembled and pre-designed structure, companies can share the installation and advertising costs while reducing local emissions by using renewable energy and fomenting clean energy vehicles.By crafting partnerships between local companies and municipalities, H2 ZERØ is a way for brands to get closer to customers while reducing their environmental footprint. Limitless possibilities of additional interactive features can be implemented in the parklet using the parklet’s interactive screen and hotspot network. H2 ZERØ achieves close contact with the public that can boost marketing campaigns, result in lower costs of customer acquisition and outreach for partner brands. Technical descriptionThe system’s energy management follows the availability of renewable energy supply, most notably solar photovoltaic. When solar energy is available, clean electricity directly powers the devices in the parklet. Excess electrical energy can be stored in a small battery for short-term storage, turned into clean hydrogen for long-term storage, and supply hydrogen fuel for fuel cell cars, motorcycles, and bikes as an additional feature. For hydrogen-optimized parklets aiming to monetize hydrogen fuel sales, energy can also be supplied from the grid, targeting periods when the renewable energy share is maximum. H2 ZERØ acts both as distributed generation and as a “load sink” to help regional governments avoid curtailment in peak wind and solar generating regions. As this approach may lead to stricter legislation, ideal partners would be companies already invested in the market of hydrogen refuelling stations.When electricity demand is higher than the panels’ generation, hydrogen is consumed on a PEM fuel cell to generate green electricity, with water as the only emission. The system can also be connected to local commerce as a way to “expand” their area for clean energy generation, reduce emissions and electricity costs over seasons.System ArchitectureThe system can be managed by Enapter’s Energy Management System (EMS) to achieve a smart integration of the following components:• Solar panels for renewable energy generation (possible to expand to other technologies if conditions allow),• Enapter’s electrolyzer for the conversion of green electricity to green hydrogen,• A battery pack for short-term electricity demand,• Hydrogen tanks, sizeable according to available energy generation and desired storage,• A compressor for hydrogen pressure regulation• Power electronicsAdditional features for the parklet:• Interactive screen• Wi-fi hotspot• Electrical plugs• Electrical bike dock (optional)• Hydrogen fuel filling outlet (optional)• Additional features can be added according to the client’s needs.H2 ZERO PARKLET Team:Eduardo Babo - Industrial DesignerGabriel Marinho - Chemical and Renewable Energy Engineer
