What are the candidate carbon sources should we pursue synthesis of hydrocarbon replacement fuels from renewable hydrogen?

by admin | Mar 29, 2021 | Potential Applications

Carbon dioxide is an unwanted effluent from many industrial processes, including all that combust carbon-based fuels. It is also a naturally occurring effluent in biological decomposition and can be found in all biological materials such as agricultural waste. Carbon...

Does electrolyzer manufacture entail use of materials likely to become scarce, expensive, and constraining, thereby constraining growth of the renewable hydrogen industry?

by admin | Mar 27, 2021 | Production

Some expensive or limited materials are used in today’s electrolyzers such as platinum, but work continues on finding substitutes with more commonly available materials (e.g., nickel) that can lower the cost with little or no reduction in efficiency. Progress is being...

Are there inherent or potential releases of toxic materials to the environment that are associated with the electrolyzer lifecycle—manufacture, operations, and decommissioning?

by admin | Mar 27, 2021 | Production

For operations utilizing PEM, there are no toxic materials released to the environment. The materials are recyclable. For liquid potassium hydroxide electrolyzers, post treatment of waste electrolyte is needed. Oregon electrolyzer start-up manufacturer HydroStar USA...

What substances are produced when hydrogen is consumed? Are there conditions under which harmful pollutants are emitted?

by admin | Mar 27, 2021 | Physical Properties

Today, most hydrogen is used as a feedstock in petroleum refining and fertilizer manufacture. These industries have a number of harmful emissions. Many of the envisioned new uses of hydrogen for transportation involve consuming hydrogen in fuel cells to produce...

Is water always consumed in envisioned uses of renewable hydrogen, or are there applications where the water can be recycled and reused in a closed system?

by admin | Mar 26, 2021 | Physical Properties

Is water always consumed in envisioned uses of renewable hydrogen, or are there applications where the water can be recycled and reused in a closed system? The electrolyzers used to produce hydrogen from electricity and water need very pure water and typically start...
