Energy Storage

The growing demand for power and the global interest in reducing CO2 emissions has stimulated an unprecedented implementation of renewable sources of energy. However, intermittent power disruptions are common when dealing with renewable resources. Energy storage eases intermittent power disruptions by storing excess power generated by renewable resources at times of low demand and distributing the power in periods of heightened demand. This helps to balance the load on the energy grid and reduce reliance on non-renewable resources. Combining grid intelligence with renewable resources and an energy storage solution, provides a dependable environmentally friendly and lower-cost supply of energy.

Renewable Energy Storage

As an energy carrier, hydrogen enables daily to seasonal storage, creating a reliable source of dispatchable green energy for society’s current and future needs. PEM electrolysis has the response time of a battery and the storage capacity of pumped hydro, providing an interface to turn excess energy generated at times of low demand into hydrogen, which can be converted back into electricity when needed, essentially improving grid stability and reducing reliance on non-renewable resources.

The global commitment to reduce carbon emissions is driving large-scale interest in employing green hydrogen for industrial applications. The standard method to produce hydrogen utilizes natural gas or coal. Depending on the method, anywhere from 10-17 tons of CO2, per ton of hydrogen, is produced. In contrast, utilizing a renewable energy source and electrolysis technology, hydrogen is generated with no CO2 emissions. Proton OnSite’s deployment of megawatt-scale PEM electrolysis helps to achieve the desired economics but also supply high-capacity hydrogen (green hydrogen) demanded by industrial applications.

Hydrogen for Power to Gas

As renewable sources of energy, such as wind and solar photovoltaics, become increasingly more vital to support global carbon footprint reduction goals, innovative energy solutions are required to match unpredictable supply and demand. Power-to-Gas (P2G) is the process of converting surplus renewable energy into hydrogen gas through PEM electrolysis technology. The hydrogen can then be injected into the natural gas grid. In doing so, the hydrogen can displace natural gas, reducing greenhouse gas emissions and reliance on high-carbon fuels. P2G is an effective means of transitioning to a ‘greener’ natural gas mix.

 

P2G also supports the anaerobic digestion processes, where microorganisms are broken-down to organic matter to produce fuels. With the addition of hydrogen, the process (otherwise referred to as methanation) greatly improves conversion rates of carbon dioxide (CO2)  to biomethane (from 60% to 95%). Hydrogen generated via PEM water electrolysis technology is key to transforming surplus electricity generated from renewables into storable methane that can be utilized within the traditional natural gas grid.

Frequently Asked Questions

Are on-site gas generators sustainable/green?

At Proton Onsite,  Yes.  In comparison to other hydrogen-generating electrolysis technology, there is no KOH required to operate Proton's generators. Also, there is no CO2 byproducts in the production of our hydrogen.  Our process consists of splitting hydrogen and oxygen via PEM electrolysis.  

What is PEM Electrolysis?

PEM (proton exchange membrane) water electrolysis simply splits pure deionized water (H2O) into its constituent parts, hydrogen (H2) and oxygen (O2), via an electrochemical reaction. When a DC voltage is applied to the electrolyzer, water fed to the anode (or oxygen electrode) is oxidized to oxygen and protons, while electrons are released. The protons (H+ ions) pass through the PEM to the cathode (or hydrogen electrode), where they meet electrons from the other side of the circuit, and are reduced to hydrogen gas.
