Site-X.

Item #: SCP-X

Object Class: Safe

Special Containment Procedures: SCP-X is contained at its place of discovery, now designated Site-X. As Site-X is able to function as an ordinary power generation facility, its continued operation serves the dual purpose of providing cover for Foundation activity at the Site and supplying power to SCP-X and Foundation facilities in the region. 25 auxiliary staff have been assigned to routine operation of the facility, under the guise of local energy authority employees.

The lower basement level of Site-X housing SCP-X itself is restricted to the immediate research team and security personnel. Staff in this area require training in basic chemical and hazardous gas safety protocols and emergency procedures (see Foundation Safety Manual, Vol. 4/Non-Anomalous Procedures, 2014 edition). Entry into the main SCP-X chamber requires the use of Level A hazmat gear. SCP-X is to be monitored at all times, with both automated and manual systems in place for the safe venting of hazardous gases.

Use of SCP-X requires a formal proposal signed by two senior members of the research team and Level 4 staff approval. No items or persons with causality or temporality-affecting properties are to be brought into the vicinity under any circumstances.

UPDATE: As a result of Incident X-1, safety standards for the Site-X basement level and SCP-X have been significantly revised. The maintenance airlock system has been redesigned to incorporate a shielded access airlock with 5-ton blast doors and the main tank walls reinforced. In addition, the basement ventilation system now incorporates emergency sealants capable of isolating the level from the remainder of the facility. Chemical and hazardous gas emergency procedures and rapid access to breathing apparatus are now required for all levels of Site-X.

Description: SCP-X is a machine in the basement level of Site-X, formerly the Lomberg Power Station in Ohio, USA. It fills the majority of the underground space and consists of the following key components:

  • a central gas storage tank with capacity of approximately 500,000 L, accessible by a maintenance airlock system
  • piping to the above-ground exhaust chimneys of Site-X, feeding exhaust gases into the tank
  • a controlled venting system leading to a secondary above-ground exhaust system
  • secondary internal gas injection systems for the purposes of testing and experimentation
  • 30 linear particle accelerators of 20 m length each, arranged in circular formation around the tank walls
  • switchable cold-cathode and ECR ion source particle emitters, designed to allow for the uniform bombardment of the tank contents with either electrons or protons
  • 30 tachyon field emitters similar to those found in SCP-3091, alternating with the particle accelerators
  • a 10,000 ton solenoid magnet encircling the tank, with field strength of up to 3 teslas
  • associated control, power and thermoregulation systems

Sustained particle bombardment of substances within the tank while the tachyon fields are active temporally displaces substances within the tank into the past or future. Use of electrons in the linear accelerators causes past displacement, while use of protons causes future displacement. The solenoid field strength determines the magnitude of the displacement; at maximum power, the tank contents are displaced approximately 800 years into the past or future.

SCP-X only affects substances in a gaseous state. The mechanism behind this is poorly understood, but is hypothesised to be due to the stability and stronger intermolecular forces of liquids and solids temporally 'anchoring' substances. Experimentation and modelling suggests displacement of liquids and solids is theoretically possible using SCP-X or a similar device, but would require over 100,000 times its current power consumption, and the apparatus used in SCP-X is not rated to withstand the excess heat that would be generated during this process.

While SCP-X was primarily a proof-of-concept, it is effective in its intended function as a means of carbon emission disposal for the power station. Carbon dioxide scrubbers (modified, but consistent with non-anomalous technology available in the 1990s) have been installed in the exhaust chimneys of Site-X, and carbon dioxide is piped directly from the chimneys into the central tank. Gases are theoretically vented through the secondary exhaust system. This is rarely observed directly given the properties of SCP-X, but elevated local carbon dioxide concentrations in the vicinity of the secondary exhausts are likely a result of past SCP-X use. Past-direction displacement of SCP-X's contents results in their reappearance in the main tank at a past date until the venting system is engaged. Given the potential for accidents as a result of unforeseen gases materialising in the tank, past-direction displacement of industrial quantities of gases was halted in 1999.

SCP-X was developed by Prometheus Labs, in the course of their activities relating to SCP-2308, and was considered one of their most promising temporal projects. Although it was initially conceived as a general-purpose temporal displacement device, Prometheus were unable to overcome the limitations in displacement of solids and were forced to consider more restricted applications. They purchased the Lomberg plant from American Electric Power in 1985 and continued development on SCP-X from that time until 1991. SCP-X meets net zero emissions standards (albeit in the present day only) for the plant at competitive running costs; SCP-X's energy requirements of 150 to 300 MW are covered by the power plant's capacity of 1200 MW and its operational costs are outweighed by eliminating requirements for carbon transport and storage. However, the significant capital investment and improvements in non-anomalous carbon capture and storage technology made SCP-X impractical for widespread commercial use, and further development was paused. Reinvestment in the SCP-X project recommenced in 1996, as a joint initiative between Prometheus and the ECSI1, but was abruptly halted by the collapse of the Prometheus conglomerate in 1998, after which SCP-X came under Foundation control.

Addendum X-1: Additional uses proposed for SCP-X are outlined in the below table.

Proposal Notes Status
General-purpose temporal displacement SCP-X can be used to transport simple materials through boiling or sublimation, with the substances returning to their original state at the destination time point depending on internal tank temperature. The additional power requirements and limits to proofing the internal SCP-X mechanisms against a wide range of temperatures are the obstacles to progress in this area. The cost-benefit ratio for previous matter transport proposals has been low, but continued submissions by interested researchers are welcome. Active
Extraterrestrial terraforming Displacement of terraforming gases such as ammonia and hydrocarbons into the past using a SCP-X-derived device may accelerate (or instantaneously produce) beneficial atmospheric change of Mars or other extraterrestrial bodies. Extraterrestrial transport of the relevant gases and materials for the construction of a sufficiently powerful device remains a problem, and public exposure from terraforming within the solar system renders the concept impractical at present. A proposal for terraforming an extrasolar planetoid or asteroid to establish a secure Foundation facility has been submitted, with transport using SCP-████. 14 candidates have been identified and O5 approval is pending. Pending
Retroactive agriculture The use of SCP-X for small-scale local climate alteration favourable to agriculture, combined with the introduction of aerosol pesticides to pre-emptively destroy insect populations before crop planting, was briefly explored by Prometheus, but the cost and inflexibility of on-site SCP-X construction was prohibitive. Exploration of this line of research has been halted due to the low convergence with Foundation goals. Withdrawn
Chemical warfare Retroactive use of chemical weapons or military atmospheric engineering is possible, but as with other uses, the need for an SCP-X device to be constructed in the target location is prohibitive. Development of a miniaturised version of SCP-X for various purposes is in progress; testing approval for retroactive targeted assassinations is on hold until the causality hazards associated with targeting sapient individuals can be resolved.2 Active
Communication A method for bi-directional temporal communication using SCP-X was developed by the Foundation in 2005, involving a letter and phrase coding system based on helium, neon and argon concentration ratios. This was designated Protocol X-Sigma and its efficacy validated by the Novikov-Scranton process.3 Guidelines have been provided to key personnel regarding the use of Protocol X-Sigma for pre-emptive measures against K-class scenarios and other catastrophic events. However, no future-to-present communications have been received at this time. It is unclear whether this is a result of a lack of relevant messages, future protocol alterations, future disabling of SCP-X or an unidentified property of SCP-X or temporal anomalies in general. Staff assigned to SCP-X should continue to monitor X-Sigma-encoded communications. Completed

Addendum X-2:

On 04/11/2016, SCP-X was severely damaged by an explosion, later determined to be the result of the sudden introduction of an unidentified flammable gas into the main tank. This resulted in the partial collapse of the basement level and 3 personnel casualties. While firefighting and rescue operations were in progress, a large quantity of VX nerve gas materialised in the damaged tank, which spread through the rest of the Site and caused an additional 33 personnel casualties and 4 civilian casualties in the surrounding area.

No recent activity of SCP-X or within Site-X was linked to this event. However, a joint Foundation-ECSI working group had recently completed a feasibility study on using an upscaled SCP-X as a last-resort measure of keeping global temperatures below [REDACTED] degrees of warming, as the ECSI had expressed interest in resuming research on SCP-X in partnership with the Foundation following the signing of the Paris Agreement in April 2016. This would have involved production of an initial 12 additional SCP-X-derived devices with components derived from commercially available and GOC technology. It was estimated that a modernised variant of SCP-X would be able to process 1 Mt of carbon dioxide per annum, but with an effectively unlimited storage capacity, and the power for temporal displacement up to 4,000 years in the past or future. No further action on the proposal has been taken at present.
