Power and Emission To X (PETX)

For power plant managers, these two things are a big problem. The first problem is the mismatch between energy demand and supply, and the second is related to emission control.

Mismatch of energy supply with demand will always occur for various reasons, one of which is that the installed electrical power provides a relatively stable electricity supply while demand is high and low at times. There can also be a mismatch because what society needs is energy in a form that is different from the existing supply. Even when the electricity supply is adequate, people will still need fuel and vice versa.

The second problem is related to emissions, all large world companies - especially energy companies, are obliged to control their emissions so that they can finally reach net zero in 2050. Currently, it is still far from 2050, but financial authorities around the world have required sustainable financial reporting, so that they can participate in monitoring and controlling efforts to reduce emissions.

The good news is, we at the Advanced Renewable Organization (ARO) have finished our study and can share comprehensive solutions to these two problems. With a product we call PETX (Power and Emission to X) reactor, the problem of energy mismatch and emissions will be resolved at once.

In short, when the electricity load is low, the excess capacity can be used to electrolyze water into Hydrogen (H2). It's just that H2 is very difficult to store or transport because it requires a very high pressure of 700 Bar or a very low temperature of minus 253 degrees Celsius. To overcome this logistical problem, H2 can be further processed into fuels such as diesel, gasoline, LPG etc.

For this we need element C in the form of CO gas, so this is our opportunity to capture CO2 from emissions and convert it into the CO gas we need. CO gas can be produced from the reaction between CO2 and C (reaction 1 in the picture), while C or Carbon can be obtained by empowering local communities to process their waste into charcoal.

The right ratio is needed between H2 resulting from electrolysis and CO resulting from carbon capture, so that both can provide maximum results when processed into the fuel mentioned above, through a reaction called Fischer-Tropsch Synthesis (FTS, reaction 3). To regulate the right H2/CO ratio, a reversible reaction is needed which is called Water Gas Shift (reaction 2). If there is a lack of H2, the reaction is directed to the right and vice versa, if there is a lack of CO it is directed to the left.

For the entire series of reactions mentioned above, of course appropriate technology is needed, so this is where the PETX reactor play it's role, with this compact reactor we should be able to overcome the energy mismatch and emissions mentioned above at once.
